• Antihistamines: These help to decrease the release of histamine, possibly calming symptoms of itching, sneezing, or runny nose. Some examples of antihistamines are diphenhydramine (Benadryl) or hydroxyzine (Atarax). These medications may cause drowsiness.
• Nonsedating antihistamines: These work like antihistamines but without the side effect of drowsiness. Nonsedating antihistamines include cetirizine (Zyrtec) or loratadine (Claritin).
• Anti-inflammatory nasal sprays: These sprays help to decrease swelling in the nose.
• Steroid nasal sprays: These sprays also help to decrease swelling in the nose. Steroid nasal sprays work best when used before symptoms start, but they also can be used during a flare-up.
• Decongestants: These help by making the blood vessels in the nose smaller, decreasing congestion. Decongestants can be purchased over the counter or by prescription.
