Doctor Explains How to Get Relief from Seasonal Allergies

In Oklahoma, allergy season usually starts in late winter or early spring and can continue through November. Tree pollen, grass, ragweed and mold are the most common triggers, often causing symptoms like sneezing, congestion and itchy eyes. Knowing when allergy season begins—and how to stay ahead of it—can help you manage symptoms more effectively and feel better longer.

This information is based on guidance from Farhad John Aminzadeh, MD, a family medicine physician at Norman Regional Health System.

When Does Allergy Season Begin in Oklahoma?

Allergy season in Oklahoma typically begins in late winter to early spring (February to March) and can last through November, depending on weather patterns.

Dr. Aminzadeh explains that our state’s changing seasons play a big role:

• Spring: Tree pollen begins as trees start blooming
• Summer: Grass pollen becomes the main trigger
• Fall: Ragweed peaks and can linger until the first freeze

“Once it gets cold, then we get relief,” he said.

Due to Oklahoma’s long growing season and high pollen counts, many people experience symptoms across multiple seasons rather than just one.

What Are the Most Common Seasonal Allergens?

Airborne substances often trigger your seasonal allergies. In Oklahoma, the most common airborne triggers include:

• Tree pollen (early spring)
• Grass pollen (late spring and summer)
• Ragweed (fall)
• Mold spores (year-round in damp environments)

Mold is often overlooked but can be a constant trigger indoors. “Mold loves wetness,” Dr. Aminzadeh said. “The most common place is in the shower. Make sure you use the fan and keep areas dry.”

According to the American College of Allergy, Asthma & Immunology, pollen and mold are among the most common environmental allergens affecting millions of Americans each year.

How Can You Reduce Allergy Symptoms at Home?

Managing your environment is one of the most effective ways to stay ahead of allergy symptoms. Dr. Aminzadeh recommends simple, practical steps:

• Keep indoor air clean:
  Close windows during high pollen days and limit outdoor allergens from entering your home
• Shower and change clothes after being outside:
  Pollen can cling to clothing, hair and skin
• Wash bedding weekly:
  Use hypoallergenic materials when possible
• Control moisture to prevent mold:
  Use bathroom fans, dry towels properly and avoid damp carpets
• Be mindful of outdoor activities:
  “If you’re cutting grass or gardening, you’re going to end up with allergies,” he said.
• Clean regularly:
  Vacuum carpets and keep surfaces dust-free

These small habits can significantly reduce daily exposure to allergens and help prevent your symptoms from worsening.

When Should You See a Doctor for Allergies?

Over-the-counter medications can help many people manage mild symptoms. However, it may be time to see a doctor or healthcare professional if:

• Symptoms persist despite medication
• Allergies interfere with sleep or daily activities
• You’re unsure whether it’s allergies or an illness
• You experience frequent sinus infections

Norman Regional primary care,walk-in clinic and urgent care doctors can evaluate your symptoms, recommend treatment options and help determine if specialist care is needed.

“If you’ve tried everything over the counter and you’re still not getting relief, then you can come and see us,” Dr. Aminzadeh said.

What Are the Most Effective Treatments for Chronic Allergies?

Treatment depends on the severity of your symptoms and your specific triggers. Common options include:

1. Over-the-Counter (OTC) Medications

Antihistamines like cetirizine (Zyrtec) or fexofenadine (Allegra) can help relieve symptoms. Nasal corticosteroid sprays, such as fluticasone (Flonase), are often more effective for congestion.

Dr. Aminzadeh also recommends rinsing your nasal passages with saline, or salt water, before using sprays to improve effectiveness.

Dr. Aminzadeh says to avoid decongestants if you have high blood pressure unless advised by your doctor.

2. Prescription Treatments

If OTC options aren’t enough, your physician may prescribe:

• Antihistamine nasal sprays
• Stronger medications specific to your symptoms

3. Allergy Testing and Immunotherapy

When symptoms are persistent, allergy testing can identify specific triggers.

Dr. Aminzadeh says that even he was surprised by his own results: after testing, he discovered unexpected allergies in his environment.

“Believe it or not, I didn't know what was causing all my allergies when I went in to an allergy specialist,” Dr. Aminzadeh said. “I knew I was allergic to cats, but once they did allergy skin tests, I found out I was more allergic to dogs than cats. I couldn't believe that part! I was also allergic to cedar. And guess what kind of a house I lived in? A cedar house.”

He says once you figure out what your trigger factors are, then you can look around and see what’s in your environment.

Allergy specialists may recommend allergy shots (immunotherapy), which gradually expose your body to allergens to build tolerance over time. The American Academy of Allergy, Asthma & Immunology notes that immunotherapy can provide long-term relief for many patients with chronic allergies.
