Allergic Conjunctivitis: what it is and what to do now

Allergic conjunctivitis makes your eyes red, itchy, watery and often a bit swollen. It usually hits soon after exposure to pollen, pet dander, dust mites or mold. Symptoms can be annoying but are rarely dangerous. The aim is to ease itching, reduce inflammation, and cut off contact with the trigger.

Quick home relief you can try today

First steps are simple: don't rub. Rubbing spreads irritants and makes inflammation worse. Rinse your eyes with cool water or use preservative-free artificial tears to wash out allergens and soothe irritation. Apply a cool compress for 5–10 minutes to reduce itching and swelling.

Over-the-counter options often help. Antihistamine eye drops (for example ketotifen where available) relieve itch fast. Oral non-drowsy antihistamines like loratadine or cetirizine can help when both eyes and nose are involved. If you wear contacts, take them out until symptoms clear and clean or replace lenses and cases.

Small lifestyle changes matter. Check pollen forecasts and keep windows closed on high-count days. Shower and change clothes after being outdoors to remove pollen. Use a HEPA filter if indoor allergies bother you, wash bedding weekly in hot water, and vacuum with a HEPA-capable vacuum.

When to see a doctor and medical options

If symptoms are mild, the steps above usually work. See a doctor if you have severe pain, blurred vision, sensitivity to light, thick yellow-green discharge (this could be bacterial), or if symptoms last more than two weeks despite treatment. A doctor can confirm the cause and rule out infections or other eye problems.

Prescription options include stronger antihistamine drops, mast cell stabilizers, or combination drops that both block and prevent allergic reactions. Short courses of steroid eye drops may be prescribed for severe inflammation but only under close medical supervision because they can raise eye pressure and increase infection risk.

For long-term control, an allergist can test for specific triggers and discuss immunotherapy (allergy shots or sublingual tablets) which can reduce sensitivity over months to years. Tell your doctor about other medications you take and any eye conditions you have.

Final practical note: if you’re unsure which eye drops to use, ask a pharmacist or your doctor. Avoid using someone else’s prescription drops. If symptoms come back every season, tracking triggers and planning ahead (starting antihistamine drops or pills before pollen season, for example) can keep your eyes comfortable.

Always consult a healthcare professional before starting prescription treatments. Quick care, avoiding triggers, and the right medicines usually get allergic conjunctivitis under control fast.
