What it means
Antihistamines block histamine, a chemical the body releases during an allergic reaction. They relieve symptoms like sneezing, runny nose, itchy eyes, hives, and allergic skin reactions. They are also used to treat motion sickness and help with sleep. First-generation antihistamines (like diphenhydramine, found in Benadryl) cause drowsiness and are best taken at night. Second-generation antihistamines (like cetirizine, loratadine, and fexofenadine) cause less drowsiness and are suitable for daytime use. Avoid alcohol while taking antihistamines. Older adults should use antihistamines with caution due to increased risk of confusion and falls from sedating effects.
