ANS: A
Antihistamines (particularly diphenhydramine and doxylamine) have sedative properties that may be used for short term treatment of mild insomnia. They are common ingredients in over-the-counter (OTC) sleep aids. Tolerance develops after only a few nights of use; increasing the dose actually causes a more restless and irregular sleep pattern. Diphenhydramine does not cause nausea. There is no restriction on taking diphenhydramine after a high-fat meal. Diphenhydramine is not an herbal medication.
