Ragweed Allergy
Posted On:
If your “fall cold” seems to come back every year and you live in or around San Antonio, ragweed pollen may be part of the problem. Many of our patients here in South Texas deal with sneezing, congestion, itchy eyes, drainage, cough, or asthma flare-ups when weed pollen rises in late summer and fall.
At AllergySA, our team knows how South Texas pollen seasons can overlap and linger. Mountain cedar, oak, mold, and ragweed can all affect patients at different times of year. Noticing symptoms that keep coming back? Ragweed allergy testing can help show whether ragweed is one of your triggers.
Key takeaways
- Ragweed season starts in late summer and can last into fall.
- Symptoms can look like a cold, sinus issue, or asthma flare.
- Allergy testing can help identify likely triggers, but diagnosis also depends on your symptoms, history, and exam.
- Treatments may include avoidance steps, medication guidance, and, for some patients, allergy immunotherapy.
- AllergySA offers care at the Medical Center and Southside locations in San Antonio.
What Is a Ragweed Allergy?
A ragweed allergy happens when your immune system reacts to the pollen as if it is harmful. This can cause inflammation in your nose, eyes, throat, sinuses, or lungs.
Ragweed pollen is light and can travel through the air. You don’t have to see ragweed growing near your home to feel symptoms. Pollen can move with the wind and collect on clothes, hair, pets, cars, shoes, and outdoor furniture.
When Is Ragweed Season in San Antonio?
Ragweed pollen, the main contributor to fall pollen, can be detected in the air as early as August and continues into October or until the first hard frost. In South Texas, warm weather can make fall allergy symptoms last for months.
For San Antonio patients, ragweed can be especially frustrating because symptoms may overlap with other allergens. Airborne mold spores are prevalent during the warmer months, and if a patient is also allergic to year-round allergens like dust mites and pet dander, symptoms can feel like they never let up.
A good rule: If you notice the same symptoms every August, September, or October, start tracking pollen counts and symptoms. Bring that pattern to your AllergySA visit.
Common Ragweed Allergy Symptoms
- Sneezing
- Runny nose
- Stuffy nose
- Itchy nose
- Postnasal drip
- Itchy, watery, or red eyes
- Scratchy or itchy throat
- Cough
- Fatigue from poor sleep
- Head pressure or sinus pressure
Some people also notice asthma-related symptoms, including:
- Wheezing
- Chest tightness
- Shortness of breath
- Coughing at night or with activity
If you have asthma and fall allergies, ragweed pollen may make breathing symptoms harder to control. AllergySA can evaluate your allergies alongside any asthma symptoms when coughing, wheezing, or shortness of breath are part of the picture.
Ragweed Allergy Testing
Allergy testing will help show whether ragweed pollen is one of your triggers. Testing usually screens for a panel of regional allergens (not ragweed alone), so your allergist can see the full picture. At AllergySA, testing may include skin (prick) testing or blood testing, depending on the patient.

Ragweed Allergy vs Cold or Sinus Symptoms
It is easy to mistake a ragweed allergy for a cold or sinus problem. The timing and symptom pattern can help.
| Symptom or pattern | More likely allergies | More likely cold or infection |
|---|---|---|
| Timing | Happens during ragweed season or around pollen exposure | Starts after being around someone sick |
| Duration | Can last weeks while pollen is high | Often improves within 7 to 10 days |
| Nasal drainage | Often clear and watery | May become thicker or discolored |
| Itching | Itchy eyes, nose, or throat are common | Itching is less common |
| Fever | Usually no fever | Fever may happen |
| Pattern | Returns around the same time each year | Less seasonal |
Sinus pressure can happen with allergies, but not every stuffy nose means a sinus infection. If congestion, facial pressure, or drainage keeps coming back, AllergySA can help evaluate whether allergies may be involved and whether sinusitis needs to be considered.
Can Ragweed Trigger Mouth or Throat Itching?
Some people with a ragweed allergy notice itching or tingling in the mouth or throat after eating certain raw fruits, vegetables, seeds, or herbal products. This can happen because the immune system confuses similar proteins in certain foods with pollen proteins.
This condition is known as pollen-food allergy syndrome or oral allergy syndrome. With ragweed, possible trigger foods may include:
- Banana
- Melons, such as cantaloupe, honeydew, or watermelon
- Cucumber
- Zucchini
- Sunflower seeds
- Chamomile tea
For many people, symptoms are mild and stay around the mouth or throat. Still, it is worth discussing with an allergist, especially if symptoms are getting worse, involve swelling, hives, vomiting, trouble swallowing, or breathing symptoms.
How to Reduce Ragweed Pollen Exposure
You cannot avoid all pollen, but small habits can lower how much pollen follows you indoors.
Try these steps during ragweed season:
- Check local pollen counts before plans that involve extended time outdoors.
- Keep windows closed at home and in the car when pollen is high.
- Shower or rinse hair before bed after being outside.
- Change clothes after yardwork, sports, or long outdoor time.
- Remove shoes near the door.
- Wipe down pets after outdoor time.
- Wash bedding often.
- Avoid drying clothes or sheets outside during high-pollen days.
- Wear sunglasses outdoors to reduce pollen near the eyes.
Feeling like you are doing everything “right” and still feeling miserable each fall? That is a sign to talk with an allergist. Avoidance can help, but it may not be enough for every patient.
Treatment Options for Ragweed Allergy
When avoidance is not enough, talk to your provider about treating your allergy symptoms. Treatment options will depend on the severity and duration of your symptoms. If a patient has asthma that is triggered by their allergies, then additional allergy testing and treatments will be discussed.
Allergy Medications
Medications may help control ragweed allergy symptoms but should be started in advance of peak season. Your provider may discuss options such as:
- Antihistamines
- Nasal steroid sprays
- Antihistamine nasal sprays
- Eye drops for itchy or watery eyes
- Saline rinses or sprays
- Asthma medications if breathing symptoms are involved
Allergy Immunotherapy
Allergy immunotherapy is a highly effective and personalized solution that treats the root cause of allergies. While medications can only temporarily mask your symptoms, allergy immunotherapy gradually desensitizes your immune system to the allergens that trigger your symptoms.
When to See an Allergist for Ragweed Allergy
Consider seeing an allergist if:
- Your symptoms return every fall
- Over-the-counter medicine isn’t helping enough
- You need allergy medicine for weeks at a time
- Congestion is affecting your sleep, school, work, or exercise
- You have asthma, wheezing, chest tightness, or shortness of breath
- You keep getting sinus pressure or sinus infections
- You are not sure whether symptoms are allergies, a cold, or sinusitis
- You want to know whether immunotherapy is an option
- You have mouth or throat itching after certain foods during pollen season

Frequently Asked Questions About Ragweed Allergy
How do I know if I have a ragweed allergy?
You may suspect a ragweed allergy if symptoms like sneezing, congestion, itchy eyes, drainage, or cough reappear in late summer or fall. The best way to know what is likely triggering your symptoms is to review your history with an allergist and consider testing when appropriate.
Can ragweed make asthma worse?
Yes, ragweed pollen can trigger asthma symptoms in some people with allergic asthma. If you notice breathing symptoms like wheezing or chest tightness during ragweed season, ask your provider whether asthma evaluation or medication changes may be needed.
Is ragweed allergy only treated with medication?
No. Ragweed allergy treatment may include reducing pollen exposure, medication guidance, testing, and, for some patients, allergy immunotherapy. The right plan depends on your symptoms and test results.
Does ragweed allergy testing hurt?
Skin testing may cause brief itching or small raised bumps where your skin reacts. Many patients tolerate it well. Your AllergySA provider can explain what to expect and whether skin or blood testing is the better option for you.
Can children have a ragweed allergy?
Yes. Children can have seasonal allergies, including ragweed pollen allergy. If your child has recurring fall congestion, sneezing, itchy eyes, cough, or asthma symptoms, AllergySA can help evaluate what may be causing them.
