When grass pollen allergy, an immune overreaction to airborne pollen from common grasses like ryegrass and timothy. Also known as seasonal allergic rhinitis, it causes sneezing, runny nose, itchy eyes, and sometimes asthma flare-ups during peak pollen seasons. This isn’t just a nuisance—it’s a daily struggle for millions, especially in late spring and early summer when grasses release massive amounts of pollen. Unlike year-round allergies from dust or pets, grass pollen allergy hits hard and fast, often catching people off guard because the triggers are invisible and everywhere outdoors.
What makes this worse is how it interacts with common medications. For example, antihistamines, drugs like cetirizine or loratadine used to block histamine release during allergic reactions can help, but they don’t fix everything. Some people still feel tired or dizzy because older antihistamines cross the blood-brain barrier. Newer ones are better, but they don’t work for everyone. And if you’re on something like venlafaxine, an SNRI antidepressant that can raise blood pressure, you need to be careful—some OTC cold and allergy meds can push your BP even higher. Even immunotherapy, a long-term treatment involving allergy shots or tablets to reduce sensitivity over time, requires monitoring. If you’re taking blood thinners or have heart issues, your doctor needs to know before you start.
Grass pollen doesn’t just affect your nose and eyes. It can make asthma worse, trigger sinus infections, and even mess with sleep and focus. People who take multiple meds—like those managing diabetes, high blood pressure, or depression—are especially at risk for hidden interactions. A simple antihistamine might seem harmless, but combined with other drugs, it can lead to drowsiness, dry mouth, or worse. That’s why knowing your full medication list matters. It’s not just about avoiding pollen—it’s about understanding how your body reacts when meds and allergens collide.
