What are some highly rated over-the-counter allergy medicines?

Some of the most popular over-the-counter allergy medications include Allegra, Claritin, Zyrtec, Benadryl and Flonase nasal spray, according to WebMD. There are numerous types of medications that can combat allergies, including decongestants, antihistamines and steroids.

Antihistamines work by blocking the allergy-causing histamines in the body, thus eliminating the body's reaction to allergens. Decongestants help relieve inflammation in the nasal tissues to relieve nasal congestion, red eyes and mucus secretions, reports WebMD. Steroids reduce the inflammation, sneezing and nasal drainage often associated with allergies. In addition, patients can apply topical steroid creams to the skin to relieve itchy rashes caused by allergies.
