Treating an Allergic Reaction

Antihistamines and decongestants may relieve minor symptoms. Antihistamines prevent symptoms such as hives by blocking histamines receptors so your body doesn’t react to the allergens. Decongestants help clear your nose, especially for seasonal allergies. But don’t take them for more than three days.

These medications are available in tablets, eye drops, and nasal sprays. Many over the counter medicines also cause drowsiness, so avoid taking them before driving or doing work that requires a lot of concentration.

Swelling, redness, and itching may be reduced with ice and topical creams that contain corticosteroids. Make an appointment with your doctor if over the counter medications don’t work. Call the doctor right away if you have allergic reactions to the medication.
