what medicines should i take for hives

ake nondrowsy forms of antihistamine pills. Taking antihistamines pills daily helps block the symptom-producing release of histamine. The newer forms of the drugs (second-generation antihistamines) have fewer side effects, such as drowsiness, than older antihistamines:

Loratadine (Claritin, Alavert)
Fexofenadine (Allegra)
Cetirizine (Zyrtec)
Levocetirizine (Xyzal)
Desloratadine (Clarinex)

Take older forms of antihistamine pills. If the newer antihistamines don’t help you, your doctor may recommend you take an older form of the drug, but only before bedtime, as it can make you drowsy. Examples include:

Hydroxyzine (Vistaril)
Diphenhydramine (Benadryl)
Chlorpheniramine (Chlor-Trimeton)
