In general, there is no cure for allergies, but there are several types of medications available -- both over-the-counter and prescription -- to help ease and treat annoying symptoms like congestion and runny nose, according to a report in WebMD. The report said the allergy drugs include antihistamines, decongestants, combination drugs, corticosteroids, and others.
Antihistamines
Antihistamines have been used for years to treat allergy symptoms. They can be taken as pills, liquid, nasal spray, or eye drops. Over-the-counter (OTC) antihistamine eye drops can relieve red, itchy eyes, while nasal sprays can be used to treat the symptoms of seasonal or year-round allergies (from WebMD).
