If your nose starts running and your eyes start itching as summer fades into fall, ragweed may be to blame. So, what is ragweed? It is a common weed that releases huge amounts of pollen in late summer and fall, and it is one of the leading causes of seasonal allergies in the United States. In Houston, where warm weather lingers well into autumn, ragweed season can feel especially long.
For most people, ragweed allergies are a nuisance that can be managed at home. But for people with asthma, ragweed pollen can trigger serious breathing problems. If you are searching for an emergency near me because an allergy or asthma attack is making it hard to breathe, East Houston Medical Center is open 24/7.
What Is Ragweed?
Ragweed is a flowering plant in the Ambrosia family. There are about 17 species in North America, with common and giant ragweed being the most widespread. These plants grow along roadsides, fields, empty lots, and riverbanks, all common sights around the Houston area.
A single ragweed plant can produce up to a billion pollen grains in one season. Because the pollen is light, wind can carry it for hundreds of miles, so you can react to ragweed even if none grows near your home.
When Is Ragweed Season In Houston?
Ragweed usually starts releasing pollen in August, peaks in mid-September, and can continue until the first freeze. In Southeast Texas, mild autumns often stretch the season into November. Pollen counts tend to be highest on warm, dry, breezy mornings, and rain can bring brief relief.
Ragweed Allergy Symptoms
- Sneezing and a runny or stuffy nose.
- Itchy, watery, or red eyes.
- Itchy throat, mouth, or ears.
- Postnasal drip and cough.
- Fatigue and poor sleep from congestion.
- Sinus pressure and headaches.
For people with asthma, ragweed pollen can also cause wheezing, chest tightness, and shortness of breath.
Ragweed And Food Allergies: Oral Allergy Syndrome
Some people with ragweed allergies notice an itchy mouth or throat after eating certain fresh fruits and vegetables. This is called oral allergy syndrome, and it happens because the proteins in these foods look similar to ragweed pollen. Common triggers include:
- Bananas.
- Melons such as cantaloupe, honeydew, and watermelon.
- Zucchini and cucumber.
- Chamomile tea and sunflower seeds.
Symptoms are usually mild and limited to the mouth. Cooking these foods often prevents the reaction. If swelling spreads to your throat or you have trouble breathing, seek emergency care right away.
How to Treat Ragweed Allergies
Most ragweed symptoms can be managed with over-the-counter options, and an allergist can help if those aren’t enough:
- Antihistamines. Medicines such as cetirizine, loratadine, or fexofenadine relieve sneezing and itching.
- Nasal steroid sprays. Sprays like fluticasone work best when you start them before ragweed season begins.
- Decongestants. These offer short-term relief for a stuffy nose, but they shouldn’t be used for more than a few days.
- Eye drops. Allergy eye drops soothe itchy, watery eyes.
- Allergy shots or tablets. Immunotherapy can reduce your sensitivity to ragweed over time. An allergist can tell you whether it is right for you.
How To Reduce Ragweed Exposure
- Check pollen forecasts. Limit outdoor time when counts are high, especially on dry, windy days and in the morning.
- Keep windows closed. Do this at home and in the car, and use air conditioning instead.
- Shower after being outside. This washes pollen from your hair and skin before it spreads indoors.
- Wash bedding weekly. Use hot water to remove pollen that collects on sheets and pillowcases.
- Use a HEPA filter. Run one in your bedroom to capture airborne pollen while you sleep.
- Wear a mask. Put one on when mowing or doing yard work, since these activities stir up pollen.
When Ragweed Allergies Become An Emergency
Ragweed allergies are rarely dangerous on their own, but they can trigger serious problems in some people. Go to the ER or call 911 if you have:
- An asthma attack that does not improve with your rescue inhaler.
- Severe shortness of breath or trouble speaking.
- Swelling of the lips, tongue, or throat.
- Hives with dizziness, vomiting, or fainting.
- Bluish lips or fingertips.
Our emergency clinic in Houston team can provide breathing treatments, steroids, and epinephrine when an allergic reaction becomes serious.

Frequently Asked Questions
Is Ragweed The Same As Goldenrod?
No. Goldenrod is often blamed for fall allergies because it blooms at the same time, but its heavy pollen is spread by insects, not wind. Ragweed is the real culprit.
How Do I Know If I Am Allergic To Ragweed?
If your symptoms return every fall and last for weeks, ragweed is a likely cause. An allergist can confirm it with a skin or blood test.
Can Ragweed Allergies Cause A Fever?
No. Allergies do not cause fever. A fever suggests an infection, such as a cold, flu, or sinus infection.
Can You Develop A Ragweed Allergy As An Adult?
Yes. Allergies can develop at any age, especially after moving to a new region with different plants.
