Aleve PM is an antihistamine and nonsteroidal anti-inflammatory drug approved by the United States Food and Drug Administration.

Aleve PM is safe and effective when consumed in an appropriate and correct fashion as directed by a clinical physician. It has proven its worth in clinical trials.

One of the most active ingredients involved in Aleve PM is diphenhydramine hydrochloride HCI which acts as a sleep aid and naproxen sodium which works as a temporary healer of pains. This drug is recommended for adults, for children above 12 years of age, definitely not for individuals who are recovering from an immediate heart surgery or for women who are pregnant, at least for the first five months unless the doctor recommends.
