Pollen is the classic springtime offender. It lands on your nose and eyes, causing runny noses, watery eyes, and that annoying itch. Dust mites hide in mattresses and carpets; they’re the reason many people cough or wheeze at night. Pet dander – tiny flakes of skin from cats or dogs – can trigger sneezing, hives, and even asthma attacks.
Food allergies vary a lot. Peanuts, tree nuts, shellfish, and eggs are the usual culprits. Symptoms can be mild (stomach upset) or severe (trouble breathing). Insect stings like bee or wasp bites often cause swelling, redness, and in some cases, a rapid drop in blood pressure.
First thing: avoid what you can. Keep windows closed during high pollen days, use allergen‑proof covers on pillows, and wash pet bedding frequently. When avoidance isn’t enough, over‑the‑counter antihistamines such as loratadine or cetirizine work fast and don’t usually interfere with blood clotting.
Be careful with pain relievers. Non‑steroidal anti‑inflammatory drugs (NSAIDs) like ibuprofen or naproxen can heighten bleeding risk, especially if you’re already on blood thinners or have a high CRUSADE Bleeding Score. If you need a painkiller, acetaminophen is a safer bet for most allergy sufferers.
If you have a food allergy, always read labels and carry an epinephrine auto‑injector if your doctor recommended one. A quick shot can stop a severe reaction before it turns into a life‑threatening situation.
For nasal congestion, saline rinses or steroid nasal sprays can clear stuffy passages without affecting clotting. Stick to the prescribed dose and avoid using spray too often.
Finally, keep a simple log. Jot down when symptoms flare, what you ate, and any new products you used. Patterns pop up fast, and you’ll have solid info to share with your doctor.
Allergies don’t have to run your life. By spotting the usual triggers, choosing safe meds, and staying aware of bleeding concerns, you can handle symptoms calmly and keep feeling good.
