At Allergy Doctor Dallas, we hear this question often. The answer depends on your symptoms, your schedule, and your goals. Let’s break it down in a simple, honest way so you can decide what feels right for you.

What Are Allergy Shots?

Allergy shots (also called immunotherapy) are a long-term option that may help your body respond differently to allergens like pollen, dust, or pet dander.

They work by giving you small, controlled doses of your triggers over time.

The goal is to:

• Help your body become less sensitive
• Reduce how strong your symptoms feel
• Support better day-to-day comfort

This is not a quick fix. It’s a gradual process that supports your immune system over time.

How Much Do Allergy Shots Cost?

Costs can vary based on your plan and how long you continue care.

Here’s a general overview:

Initial Testing

• A one-time cost
• Most insurance plans cover testing up to once per year
• Repeat skin testing is usually only needed every 3–5 years
• Rarely, more than the 80 tests allowed are needed in the first year
• In that case, patients may choose to purchase additional tests out of pocket

Allergy Extracts

Once testing is complete, Dr. Baxter will prescribe your immunotherapy.

• Multiple vial sets may be needed to treat all diagnosed allergies
• Each vial set contains 30–45 doses

Billing can vary by insurance company. In many cases:

• Some doses are billed right away
• Others may be billed 1–3 months later

This can feel confusing, since patients start all extracts at the same time. These rules are set by insurance companies, often with the goal of shifting costs if coverage changes.

Some carriers also use their own definitions of an allergy extract dose, instead of the standards set by the AMA (CPT code book). This has created challenges in recent years.

If this applies to your plan, you may need to pay for part of your treatment out of pocket to begin. Our team will explain this clearly if needed.

Shot Visits

• Billed per visit

Insurance Coverage

• Most plans cover allergy testing and immunotherapy as standard care
• Your cost depends on:
  • Deductible status
  • Coverage after deductible

For some patients, costs are fully covered. For others, total expenses may not reach the deductible.

Our staff will review your benefits and help you understand your responsibility before you start.

Uninsured Patients

• Cash options are available for testing and treatment
• Payment plans can be tailored to your budget
• Pricing is similar to insured rates (not inflated “retail” rates)

How Treatments Progress

You may start with weekly shots or choose a faster option called cluster treatments.

Standard Build-Up

• Weekly visits at the start

Cluster Option

• Three visits, each lasting about 3 hours
• Six treatments per visit (every 30 minutes)

Clusters allow you to complete about 4.5 months of progress in the first month.

Most patients notice some benefit by the end of the third cluster. After that:

• You continue weekly for about 5–10 visits
• Then begin spacing treatments out

Eventually, visits can be spaced every 2–4 weeks, based on how you feel. Some patients can even sense when they’re ready for their next dose.

How Much Time Do They Take?

This is one of the biggest factors to consider. Allergy shots happen in phases:

1. Build-Up Phase

• 1–2 visits per week
• Lasts about 3–6 months

Or (Cluster Option):

• Three longer visits upfront
• Can shorten build-up time to about 2 months

2. Maintenance Phase

• 1 visit every 2–4 weeks
• Continues for 3–5 years

3. Recheck

After 3–4 years:

• A follow-up skin test is recommended
• This helps track changes and identify any new allergies

Each visit is quick, but you’ll need to stay for a 30-minute observation period after your shot.

Good to know:

• Many patients schedule visits around work or errands
• Consistency matters for best results
• Shot hours include 12–1 (helpful for lunch visits)
• The office closes 1–2 and reopens at 2

When Will You See Results?

Results vary from person to person.

Some people notice changes within a few months. Others take longer.

You may experience:

• Fewer allergy flare-ups
• Less need for medications
• Milder symptoms during peak seasons
• Fewer sinus infections each year

Allergy shots are designed to support long-term symptom control, not instant relief.

Pros and Cons to Consider

Potential Benefits

• Long-term symptom support
• May reduce reliance on daily medications
• Targets the root cause of allergies

Things to Keep in Mind

• Time commitment
• Regular appointments required
• Gradual results

To help with timing:

• We offer cluster buildup to speed up progress
• We work with your schedule, especially if you travel frequently

Are Allergy Shots Worth It?

For many people in Dallas, allergies last most of the year. Between pollen, weather changes, and indoor triggers, symptoms can feel constant.

Allergy shots may be worth it if:

• Symptoms affect your daily life
• Medications are not enough
• You want a long-term approach with less medication

They may not be the best fit if:

• Your schedule is very busy or unpredictable
• You prefer short-term options
• Symptoms only last a few weeks each year

A helpful rule of thumb:

• If symptoms last about 3 months a year for 2 years in a row, it’s worth considering
• Or, if symptoms are severe for even one month, it may still be worth it

A Personalized Approach Matters

There is no one-size-fits-all answer.

At Allergy Doctor Dallas, we take time to understand your symptoms, lifestyle, and goals. From there, we help you decide if allergy shots are a good fit.

Final Thoughts

Allergy shots are a commitment—but they offer the possibility of long-lasting relief.

A large meta-analysis found:

• 85% of patients benefit from immunotherapy
• Average symptom relief is about 75%
• Medications alone provide about 30–40% relief
• After 3–5 years:
  • About 2/3 of patients can stop treatment long-term
  • About 1/3 may relapse within 6 months to 2 years and need additional care

If you’re tired of managing symptoms day after day, it may be worth talking with a specialist.

A Simple Guide for Dallas Patients

If you struggle with allergies year after year, you may have heard about allergy shots. Many patients ask us about them at Allergy Doctor Dallas. But how do allergy shots actually work? Let’s break it down in simple terms so you can understand what they do and how they may support allergy care over time.

What Are Allergy Shots?

Allergy shots are a type of allergy immunotherapy. They expose your immune system to very small amounts of an allergen. An allergen is a substance that triggers an allergic reaction. Common examples include:

• Tree pollen
• Grass pollen
• Weed pollen
• Dust mites
• Pet dander
• Mold

The goal is to help your immune system slowly become less sensitive to these triggers. Over time, some patients notice that their allergy symptoms become easier to manage.

How Allergy Shots Work in the Body

Allergy shots train your immune system in small steps.

Here is the simple idea:

1. A tiny amount of an allergen enters your body through an injection.
2. Your immune system recognizes it.
3. The dose slowly increases over time.
4. Your immune system may learn to react less strongly.

This process helps the body build tolerance to allergens. Because the change happens slowly, the treatment plan usually takes place over several months or longer.

FOR SCIENCE NERDS: 

Here are some of the science concepts used to describe what happens when we give allergy shots:

• TH2 cells are suppressed. 

• Inhibition of IgE dependent activation of mast cells and basophils

• Immune activation toward Th1 responses and B regulatory cells

• Production of allergen-neutralizing antibodies

• Induction of innate regulatory lymphoid cells, or Tregs

• Suppression of pro-inflammatory Th2 and T follicular helper cells

• Exhaustion of Th2A cells

• Exptression of nasal and systemic IgA antibodies

Allergen neutralizing antibodies: capture allergens in the mucosal surface, inhibit mast cell activation, and prevent  FcERII mediated allergen presentation

Early changes with SCIT or SLIT: 

• Reduction in Degradation of Mast cells and basophils 

• Decrease in histamine release

• Decreased production of IL4, IL5, IL13, IL9

• Decreased proliferation of eosinophils

Late changes with high-dose immunotherapy: 

• Increase in regulatory dendritic cell markers

• Expression of complement component 1

• Expression of stabilin-1

• Promotes dendritic cells to secrete IL12 , IL 27 and IL10 

• Down regulates CD86

• Modulates innate lymphoid cells or ILC2s. –suppresses them. 

• Induces a novel ILC that can produce IL10 

• ILC1s are increased and express CD25

So you see, it’s very complicated. Taking the shots is simple . Your body does the rest. 

Why Allergies Are So Common in Dallas

Living in Dallas means dealing with long allergy seasons.

North Texas often has high levels of:

• Tree pollens like oak, pecan and cedar 
• Weed pollens like ragweed, sagebrush, marshelder, carelessweed
• Grass pollens like bermuda, timothy, johnson, rye 
• Mold spores like alternaria, aspergillus, helminthosporium, penicillium ( the spores are not the same as the medication)

Many Dallas patients experience symptoms for much of the year. These symptoms may include:

• Sneezing
• Stuffy nose
• Runny nose
• Itchy eyes, nose, ears, skin and sometimes palate. 
• Sinus pressure
• Headaches
• Fatigue 
• Poor quality sleep 
• Mouth breathing
• Coughing 
• Secondary sinus infections

Supportive therapies like allergy immunotherapy may be discussed with Dr. Baxter when symptoms continue despite routine care.

Who Might Consider Allergy Shots?

Not everyone with allergies needs allergy shots. But some patients may discuss this option with Dr. Baxter.

She may talk about immunotherapy if you:

• Have moderate to severe allergy symptoms for three months of the year, 2 years in a row. 
• Need frequent allergy medications
• Find medications working less and less well  
• Experience long allergy seasons
• Want a long-term approach to allergy management with relief that lasts for years after treatment concludes. 

At Allergy Doctor Dallas, Dr. Baxter helps patients understand their allergy triggers and explore supportive care options.

What the Allergy Shot Process Looks Like

Allergy shots usually follow two phases.

1. Build-Up Phase

During this stage:

• Injections happen regularly
• The allergen dose slowly increases
• The goal is gradual immune exposure

2. Maintenance Phase

Once the target dose is reached:

• Shots occur less often
• The immune system continues to receive steady exposure

Each patient’s plan may look a little different. Dr. Baxter will guide the process and monitor your response.

Are Allergy Shots Safe?

Allergy shots have been used for many years under medical supervision.

Like many medical therapies, they may cause side effects for some people. These may include:

• Mild redness or swelling at the injection site
• Temporary allergy symptoms

Serious reactions are rare but possible. Because of this, allergy shots are given in a medical setting where staff can monitor patients after each injection. Note: We prescribe and require that patients carry epinephrine to reverse reactions in case symptoms start after the 30-minute observation period. If a reaction occurs while you are under our care, we will provide the medications to treat it, and we will observe you for a minimum of one hour after the reaction. Dr. Baxter will discuss potential risks and safety steps before starting therapy.

How Allergy Specialists Personalize Treatment

Every patient’s allergies are different.

At Allergy Doctor Dallas, Dr. Baxter often starts with allergy testing. This helps identify the substances that trigger your symptoms.

From there, your care team may discuss:

• Environmental changes that reduce allergen exposure
• Medication review
• Education about immunotherapy options

The goal is to help patients better understand their immune response and explore supportive care strategies.

When to Talk to an Allergy Specialist

You may benefit from an allergy evaluation if you experience:

• Allergy symptoms most of the year
• Poor sleep due to congestion
• Frequent sinus pressure
• Limited relief from over-the-counter medications

An allergy specialist like Dr. Baxter can help determine what triggers your symptoms and review options that may support long-term symptom control.

Supporting Allergy Care in Dallas

Allergies can disrupt sleep, work, and daily life. The good news is that several supportive care strategies exist. If you live in Dallas and want to learn more about allergy immunotherapy, the team at Allergy Doctor Dallas can help you better understand your options.

With the right information and guidance, many patients feel more confident managing their allergies.

The post How Do Allergy Shots Work? appeared first on Allergy Doctor Dallas.

Let’s talk about why this happens—and what you can do next.

First: Did Your Allergies Change?

Allergies aren’t static. They shift over time.

You may have:

• Moved to a new area (hello, Texas pollen) or an apartment or home where a prior occupant had a pet to which you’re allergic . 
• Developed a new sensitivity: allergies can change throughout your life 
• Had changes in your immune system!
• Increased exposure to dust, pets, or mold. Sometimes a home can have a hidden leak, for example. 

North Texas has long allergy seasons. Tree, grass, and weed pollens overlap. About the only time there is no pollen in the air in Texas is when we are frozen solid, like we were in late January 2026! Other than that, you can assume pollen is part of the air you breathe. That means your body is facing triggers daily. When sensitivity increases, symptoms can break through medications that once felt strong.

Your Body Can Adapt to Medication

Some people build tolerance to certain allergy medications. This doesn’t happen to everyone. But over time, your body may respond less to the same dose.

You might notice:

• Shorter relief time
• More breakthrough sneezing
• Nighttime congestion returning

If you’ve taken the same medication for years, it may be time to review your plan. 

You Might Be Treating the Wrong Problem

Not all “allergy symptoms” come from allergies.

Conditions that look similar:

• Non-allergic rhinitis
• Sinus infections
• Hormone-related congestion
• Irritant reactions (like smoke or strong scents)

If antihistamines aren’t helping at all, allergies may not be the only cause. Testing can clarify what your immune system actually reacts to.

The Dose or Timing May Be Off

Small details matter.

For example:

• Some medications work best daily—not as needed
• Nasal sprays require proper technique
• Missing doses reduces effectiveness
• Combining certain products can improve symptom control under medical guidance

Many people don’t get the full benefit simply because of how they use the medication. 

Dallas Pollen Is Intense

Living in Dallas means long seasons and high pollen counts. Cedar, oak, ragweed, various grasses—you name it.

Even if your medication hasn’t changed, the environment does. A higher allergen load can overpower mild treatment plans.

When to See an Allergy Specialist

If you notice:

• Symptoms lasting most of the year
• Poor sleep from congestion
• Frequent sinus pressure
• Ongoing medication changes with little relief

It may be time for a deeper evaluation.

At Allergy Doctor Dallas, we focus on identifying triggers and building a personalized, supportive care plan. The goal is to help you better understand your immune response and explore options that may support symptom control over time.

What Allergy Care Can Include

Depending on your needs, supportive care may involve:

• Updated allergy testing
• Reviewing your current medications
• Environmental control guidance
• Education about long-term options like allergy immunotherapy

Immunotherapy works by gradually exposing your immune system to specific allergens in controlled amounts. It is designed to support long-term immune tolerance. Results vary from person to person, and your provider will discuss whether it may be appropriate for you.

You’re Not “Immune” to Your Meds

If your allergy medication stopped working, it doesn’t mean you’re out of options.

It means your body—or your environment—may have changed.

And that’s something worth exploring.

If you live in Dallas, TX and struggle with ongoing allergy symptoms, the team at Allergy Doctor Dallas can help you better understand what’s happening and discuss supportive next steps.

The post Why Your Allergy Medications Stopped Working appeared first on Allergy Doctor Dallas.

Here’s a simple guide from Dr. Baxter.

What Is 12-Hour Sudafed?

12-hour Sudafed contains 120 mg of pseudoephedrine, a decongestant.

It works by:

• Shrinking swollen blood vessels in the nose
• Opening nasal passages
• Reducing sinus pressure
• Helping you breathe more easily

Each dose is designed to last about 12 hours, so it can be taken up to two times per day. However, decongestants can cause insomnia, so many patients prefer to take the 12 hour formulation only in the morning. Once a day is often preferable to twice when side effects are considered. 

There are 30 mg and 60 mg doses of pseudoephedrine available as well. Patients who are sensitive to stimulants may prefer the shorter-acting 30 mg dose, which helps for about 4 hours. 

Important: Sudafed does not treat the cause of allergies. It only helps ease symptoms for a short time.

When Patients Use It

Many people use 12-hour Sudafed for temporary relief from:

• Seasonal allergies (pollen, mold, ragweed)
• Indoor allergies (dust, pet dander)
• Sinus pressure or fullness
• Cold-related congestion
• Ear pressure during illness or travel

At Allergy Doctor Dallas, we often discuss Sudafed as a supportive option for short-term symptom relief.

How to Take It Safely

Pseudoephedrine is kept behind the pharmacy counter. You do not need a prescription, but you must show ID.

Safety tips:

• Follow the label directions
• Do not take more than recommended
• Avoid taking it late in the day (it may affect sleep)
• Do not crush or chew 12-hour tablets
• Limit use to short periods unless your doctor advises otherwise

If congestion lasts more than a week, it may be time for a medical evaluation.

Possible Side Effects

Most people tolerate Sudafed well, but some may notice:

• Trouble sleeping
• Feeling nervous or jittery
• Faster heart rate
• Headache
• Dry mouth

Stop use and contact a healthcare provider if you feel chest pain, severe dizziness, or unusual symptoms.

Who Should Talk to a Doctor First?

Sudafed may not be right for everyone. Check with your provider if you have:

• Uncontrolled High blood pressure
• Heart disease
• Thyroid disease
• Glaucoma
• Prostate problems
• Anxiety or sleep issues
• Pregnancy or breastfeeding

It can also interact with some medications, including certain antidepressants and blood pressure drugs.

The team at Allergy Doctor Dallas can help you decide what is safe for your health history.

What About Combination Products? 

Often, people like to choose combination products like Allegra D, Zyrtec D, or Claritin D. Some of the products offer a choice between 12-hour and 24-hour products. Patients choose a 12-hour product because the 240 mg dose of pseudoephedrine found in the 24-hour products is simply too much for them. 

Something few patients realize is that the 12-hour products contain only half of a usual dose of Claritin or Zyrtec ( 5 vs 10 mg in both cases ) and only 60 mg vs 180 mg of Allegra.

What this means is that patients taking combo products often need additional antihistamines, so in those cases, they would get more relief from taking separate doses of decongestant and antihistamine. 

This is not an error by the manufacturers. It’s a flaw in the FDA requirements for new formulations that combine 2 medications.

Fun fact: Since 120 mg of pseudoephedrine lasts 12 hours and Zyrtec and Claritin 10 mg doses are approved for 24-hour dosing, the companies are only allowed to include half of the 24-hour dose. In reality, these medications have half-lives of about 14 hours, so re-dosing is often needed, and the 5 mg allowed in the 12-hour combination is completely inadequate to control symptoms. 

Sudafed vs. Allergy Treatment

Sudafed helps with congestion, but it does not control the allergy response.

Long-term allergy care may include:

• Nasal steroid sprays
• Antihistamines
• Allergen avoidance strategies
• Allergy testing
• Allergy shots (immunotherapy)

If you need Sudafed often, your symptoms may not be well controlled.

When to See an Allergy Specialist

Schedule a visit if you have:

• Congestion that lasts weeks or months
• Frequent sinus pressure or infections
• Symptoms that affect sleep or daily life
• Ongoing need for decongestants
• Poor relief from over-the-counter products

At Allergy Doctor Dallas, we focus on identifying the cause of your symptoms and developing a care plan that meets your needs.

The Bottom Line

12-hour Sudafed can provide temporary relief from nasal congestion and sinus pressure. It works best as a short-term, supportive option—not a long-term solution.

If you rely on decongestants often, it may be time to look deeper at the cause of your symptoms.

At Allergy Doctor Dallas, Dr. Baxter helps patients find personalized, supportive care so they can feel more comfortable around pets and other animals.

Let’s break it down in simple terms.

What Are Animal Allergies?

Animal allergies happen when your immune system reacts to proteins from animals. These proteins are found in:

• Dander (tiny flakes of skin)
• Saliva
• Urine
• Fur or feathers

When these particles become airborne, you can breathe them in. Your immune system treats them like a threat, even though they are harmless.

Common Symptoms

Animal allergy symptoms often look like seasonal allergies. You might notice:

• Sneezing
• Stuffy or runny nose
• Itchy or watery eyes
• Coughing or wheezing
• Skin rash or hives
• Chest tightness or shortness of breath

Symptoms may start right away or build over time.

When you bring home a new pet, allergen levels start low and increase over several months. They often reach steady levels around six months. Because of this, symptoms may not appear right away.

You can also develop a pet allergy at any time. Even if you’ve had a pet for years, new symptoms can still happen.

Which Animals Cause Allergies?

Any animal with fur or feathers can trigger symptoms. Common sources include:

• Cats
• Dogs
• Rabbits
• Guinea pigs
• Hamsters
• Birds
• Horses and farm animals

Fun fact: Fur is not the problem. The real trigger is the protein on the animal’s skin and in its saliva.

This means there is no truly hypoallergenic dog or cat. Even breeds with hair instead of fur still produce skin proteins that can cause symptoms.

Dander in Your Home: Why It Sticks Around

Pet dander levels vary by animal.

• Larger dogs often produce more dander
• Female dogs may trigger fewer symptoms than males
• Cats can vary up to 500 times in how much allergen they produce

If you add a second cat and suddenly have symptoms, the new pet may produce more allergen.

Cat dander is especially persistent. It can stay in a home for months—or even years—after the cat is gone. It settles into carpets, furniture, and dust.

If you have cat allergies, try to ask whether a home or apartment previously had cats before moving in. Lingering allergens can trigger symptoms quickly, especially in small spaces.

New cat foods that reduce the Fel d 1 allergen are now available. They may help lower allergen levels, but existing dander in the home can still cause symptoms.

My favorite story about cat antigen persistence is this: a group of allergists heard that a small island off the coast had not had a living cat present in five years. They traveled to the island and took samples of dust from homes that had previously had cats. Cat dander was still detectable in every home. So if you’re cat allergic, before you rent an apartment or buy a home, do your best to find out if there was a cat there before and avoid it if the answer is yes. I had a patient move into a small building and have severe asthma almost immediately. Fortunately, the landlord had cat allergy asthma too, and he found another tenant to trade apartments so she could stay in the building! 

Why Do Animal Allergies Happen?

Your immune system protects you from harmful germs. With allergies, it becomes overprotective.

When you come into contact with animal proteins, your body releases chemicals like histamine. This leads to:

• Swelling
• Itching
• Mucus
• Airway irritation

Genetics, environment, and repeated exposure all play a role.

If symptoms keep coming back, allergy testing can help identify your specific triggers.

How Dr. Baxter Can Help

Dr. Baxter at Allergy Doctor Dallas is known for her caring, personalized approach. She takes time to understand your symptoms, lifestyle, and exposure to animals.

Your treatment plan may include:

Allergy Testing

• Skin or blood testing to identify animal triggers
• Clear results to guide your care

Medication Support

• Antihistamines
• Nasal sprays
• Eye drops
• Other options to help manage symptoms

Allergy Shots (Immunotherapy)

• A long-term treatment that helps your immune system become less sensitive over time
• Given on a regular schedule
• Designed to support symptom control and improve comfort

Each plan is tailored to your needs, with the goal of helping you live more comfortably around animals.

Tips to Reduce Exposure at Home

If you have a pet, these steps may help:

• Keep pets out of the bedroom
• Use HEPA air filters
• Wash hands after contact
• Bathe pets regularly (if appropriate)
• Vacuum often with a HEPA vacuum

These changes work best when combined with medical care.

When to See an Allergist

Consider a visit if:

• Symptoms occur around animals
• Over-the-counter medicines don’t help enough
• You avoid pets because of symptoms
• You want long-term management options

At Allergy Doctor Dallas in Dallas, TX, Dr. Baxter helps patients find practical, supportive solutions that fit real life.

The post Animal Allergies: Why Pets Can Make You Sneeze (and How We Can Help) appeared first on Allergy Doctor Dallas.

Right now, we are in the peak of mountain cedar, also called juniper, season. Texas is one of only three states with pollen in the air all 12 months. Aren’t we lucky?

Four species of juniper are found in North Texas. Red berry juniper pollinates in the fall. Mountain cedar (juniper mexicana), which is an invasive species, pollinates from November through February. Eastern red cedar and Western red cedar pollinate with the spring trees in March and April. Some very sensitive patients have symptoms from September through April if they react to all four types.

This guide explains common nasal allergy symptoms and how allergy shots can be a supportive option for some patients.

What Are Nasal Allergies?

Nasal allergies, also called allergic rhinitis, happen when your immune system reacts to things in the air. These triggers are harmless for most people, but your body treats them like a threat.

Common triggers include:

• Tree, grass, and weed pollen
• Dust mites
• Mold spores
• Pet dander

When you breathe these in, your nose releases chemicals like histamine. That response causes symptoms.

Common Nasal Allergy Symptoms

Symptoms can be mild or intense. They often come and go, which makes them frustrating.

You may notice:

• Sneezing fits
• A runny or stuffy nose
• Itchy nose, eyes, or throat
• Postnasal drip
• Sinus pressure or headaches

For many people, poor sleep and daytime fatigue follow.

Why Symptoms Can Stick Around

Avoiding triggers helps, but it is not always possible. In Dallas, outdoor allergens can stay in the air for long stretches. Indoor allergens, like dust mites, can linger year-round. Over time, your immune system may stay on high alert. That can make symptoms feel constant.

Another challenge this time of year is that viral infections are also circulating. The flu is very active, and the strain of Influenza A currently prevalent in Dallas is particularly severe. Because a newer strain became widespread after this season’s vaccines were produced, the flu shot is not quite as protective as we would like. It still helps, though, and it is not too late to receive one. There is also some COVID circulating.

If you have allergies and then develop a viral illness like influenza or COVID, the existing swelling in your nasal passages can make recovery more difficult. You are at a higher risk of developing a secondary bacterial infection after the virus damages your respiratory membranes. This is what we call a comorbid condition.

A common pattern to watch for is this: if you begin to feel better after your fever breaks and then worsen again around days 6–8, you may have developed a post-viral sinus or bronchial infection. If this happens, please contact our office so we can make sure you receive the treatment you need.

What Are Allergy Shots?

Allergy shots are also known as allergen immunotherapy. They involve regular injections that contain very small amounts of specific allergens.

The goal is to help your immune system become less sensitive over time.

Key points to know:

• Shots are tailored to your allergy test results
• Doses increase slowly under medical guidance
• Treatment follows a set schedule

Allergy shots do not work overnight. They are a long-term, supportive therapy.

How Allergy Shots May Support Symptom Control

For some patients, allergy shots may:

• Reduce how strongly the body reacts to allergens
• Lessen the frequency of nasal symptoms
• Support better day-to-day comfort

Results vary from person to person. Your allergist will review risks, benefits, and expectations before you start.

Who Might Consider Allergy Shots?

You might ask about allergy shots if:

• Symptoms last most of the year
• Medications do not give enough relief
• Allergies affect sleep, work, or school
• You want a long-term management option

A full evaluation helps decide if this approach fits your needs.

Care You Can Trust in Dallas, TX

At Allergy Doctor Dallas, we focus on clear answers and personalized care. We take time to explain your options and support you at every step.

If nasal allergies slow you down, Dr. Barbara Baxter can help you explore safe, evidence-based strategies.

The post Nasal Allergies: Why Your Nose Won’t Quit (and How Allergy Shots May Help) appeared first on Allergy Doctor Dallas.

Your immune system works hard every day to protect your body. To do that well, it needs good blood flow, balanced inflammation, and enough oxygen. When inflammation becomes ongoing or circulation slows down, your immune system may not work as efficiently as it should.

At Allergy Doctor Dallas, we offer Hyperbaric Oxygen Therapy (HBOT) as a supportive therapy alongside immunology care. HBOT does not treat immune or allergic conditions, but it may help support your body’s natural healing processes and overall immune balance.

What Is Hyperbaric Oxygen Therapy?

During Hyperbaric Oxygen Therapy, you relax in a comfortable chamber while breathing a higher level of oxygen than normal air. The chamber gently increases air pressure, which allows more oxygen to enter your bloodstream.

This extra oxygen travels through the liquid “serum” part of your blood and reaches tissues that may not get enough oxygen due to inflammation or poor circulation. As a result, HBOT helps your body deliver oxygen more effectively where it’s needed.

Why Oxygen Matters for Immune Health

Oxygen plays an important role in how immune cells work. These cells use oxygen to communicate, respond to inflammation, and support healing.

When tissues don’t get enough oxygen—often due to chronic inflammation or circulation problems—the immune system may struggle to stay balanced. By increasing oxygen levels in the body, HBOT may help support healthier immune activity.

How HBOT May Support the Body

HBOT does not diagnose or treat immune disease, but it may support the body in several helpful ways:

• Helps Calm Ongoing Inflammation

Improved oxygen delivery may help the body manage inflammatory signals and support recovery.

• Supports Normal Immune Cell Activity

Immune cells rely on oxygen to do their job. HBOT may help support these cells by improving oxygen availability in tissues.

• Encourages Healing and Recovery

Healthy immune function depends on strong tissue repair. HBOT supports processes like new blood vessel growth and cell repair.

• Improves Oxygen Delivery to Hard-to-Reach Areas

HBOT helps oxygen reach areas with reduced blood flow, supporting overall healing and balance.

Who May Consider HBOT?

Dr. Barbara Baxter at Allergy Doctor Dallas may discuss HBOT if you:

• Experience ongoing or recurring inflammation
• Have immune-related concerns and want supportive care
• Heal slowly from inflammation or tissue stress
• Want to add a supportive therapy to your current treatment plan

We evaluate each patient individually and review medical history, current health, and goals before recommending HBOT.

Part of a Whole-Person Care Plan

Hyperbaric Oxygen Therapy works best as part of a comprehensive care plan. It does not replace allergy treatment, immunology care, or prescribed medications.

When used thoughtfully and under medical supervision, HBOT may support oxygen delivery, healing, and inflammatory balance alongside conventional treatment.

Some people lose their spleen after a car accident, sports injury, surgery, or illness. Afterward, many ask a simple question: What does the spleen actually do?

At Allergy Doctor Dallas, patients often ask this after learning they no longer have one (asplenia). Understanding the spleen can help you protect your health and respond quickly to infections.

Let’s walk through it in simple terms.

What Does the Spleen Do?

The spleen is an important part of your immune system.

It is also the largest lymphatic organ in the body.

One key job of the spleen is to filter bacteria from your blood. When harmful germs enter the bloodstream, the spleen helps remove them before they spread.

The spleen also helps the body recognize certain bacteria and respond to infection.

Without a spleen, the body can still function. However, the immune system may have a harder time clearing some infections.

Why Infections Can Be More Serious With Asplenia

People who do not have a spleen are called asplenic.

Without the spleen’s filtering action, bacteria can spread through the bloodstream more quickly.

Because of this, infections can become serious faster than they might in other people.

Doctors often advise people without a spleen to seek medical care sooner when symptoms of infection appear.

This early response can help reduce the risk of complications.

Signs of Infection to Take Seriously

If you do not have a spleen, it is important to watch for symptoms of infection.

Call your doctor if you notice:

• Fever
• Chills
• Sudden illness
• Unexplained fatigue
• Rapid worsening of symptoms

Even mild symptoms can sometimes progress quickly.

Your healthcare provider may decide to evaluate you or start treatment while they determine the cause.

Antibiotics May Be Recommended in Certain Situations

Doctors sometimes recommend preventive antibiotics for people without a spleen during higher-risk situations.

These may include:

• Surgical procedures
• Dental procedures
• Certain invasive medical procedures

Doctors may also evaluate the need for antibiotics after:

• Dog bites
• Tick bites
• Other animal bites

These exposures can introduce bacteria into the body.

Your healthcare provider will guide you based on your health history and the situation.

Why Certain Bacteria Are a Concern

Some bacteria carry a protective outer coating called a capsule.

These bacteria can be harder for the immune system to detect and remove.

Examples include:

• Streptococcus
• Pneumococcus
• Haemophilus influenzae
• Meningococcus

Because these bacteria can cause serious infections, doctors often recommend preventive steps for people without a spleen.

Vaccines Can Help Support Protection

Vaccines help the immune system recognize specific bacteria before exposure.

For people without a spleen, doctors often recommend vaccines that target the bacteria mentioned above.

These may include vaccines for:

• Pneumococcus
• Meningococcus
• Haemophilus influenzae type B (Hib)

Annual influenza (flu) vaccination is also important.

After the flu, some people develop secondary bacterial infections caused by the same organisms listed above.

Vaccination can help support the body’s ability to respond.

Working With Your Doctor

If you do not have a spleen, it helps to review your vaccination history with your doctor.

Your provider may recommend vaccines such as:

• Pneumococcal vaccination
• Meningococcal vaccination
• Haemophilus influenzae type B vaccination
• Annual flu vaccination

Some vaccines may require more than one dose or booster over time.

Your doctor can review what you have already received and discuss what may be appropriate based on current medical guidance.

Supporting Your Health After Splenectomy

Living without a spleen requires extra awareness, but many people live full and healthy lives.

Helpful steps may include:

• Staying up to date on recommended vaccines
• Seeking care early when fever appears
• Following your doctor’s guidance before procedures
• Monitoring symptoms after bites or infections

According to experts, the eight most common food allergies are:

• Milk
• Egg
• Wheat
• Soy
• Peanuts
• Tree nuts
• Shellfish
• Fish

The American College of Allergy, Asthma & Immunology notes certain allergies (e.g., milk, eggs and soy) may disappear over time, while others (e.g., nuts and fish) are more likely to last a lifetime.

Food Allergy Symptoms: Mild to Life-Threatening

Food allergy symptoms may be mild (e.g., itchy mouth) or potentially deadly (e.g., anaphylaxis). FARE has reported that food allergy reactions are responsible for more than 200,000 emergency department visits every year.

Food allergy symptoms include itching, sneezing, runny nose, abdominal cramping, nausea, vomiting, diarrhea, rash, eczema, hives and swelling of the lips/mouth (also referred to as oral allergy syndrome when it occurs as the only symptom). Another food allergy event is feeling like food is stuck in the esophagus during swallowing, which could be indicative of a condition called eosinophilic esophagitis.
