Excedrin PM

Excedrin PM is an over the counter medication used to treat headaches, minor aches and pain, and difficulty sleeping due to minor pain.

It is a single product containing 3 ingredients: acetaminophen, aspirin, and diphenhydramine. Acetaminophen belongs to a group of drugs called analgesics, which is thought to work by blocking pain signals from reaching the brain. Aspirin belongs to a group of drugs called salicylates, which work by stopping the production of certain natural substances that cause fever and pain. Diphenhydramine belongs to a group of drugs called Histamine H1 Antagonists (antihistamine). It works by blocking the action of histamine and allergy symptoms, but is also known to cause sleepiness and drowsiness. 

This medication comes in a caplet form, and is usually taken once a day at bedtime with a full glass of water.

Common side effects of Excedrin PM includes stomach upset and dizziness. Excedrin PM can also cause drowsiness. Do not drive or operate heavy machinery until you know how Excedrin PM affects you.
