Antihistamines help the most with sneezing, watery drainage, and itching which are often seen with allergies.
Older antihistamines (like benadryl
) can make people sleepy and should be used with caution; newer antihistamines (like Claritin
) & allegra
) are less likely to be sedating. Because of their drying effect, some doctors recommend avoiding antihistamines during a respiratory infection.
