HOW EXCEDRIN PM WORKS
It contains 3 active ingredients: Acetaminophen, aspirin, and diphenhydramine. Acetaminophen belongs to a group of drugs known as analgesics and though it is not fully understood how it works, it is believed that it works by elevating the body’s pain threshold, thereby allowing you to tolerate more pain, or by blocking pain signals from traveling to the brain, so you don’t feel any pain, hence providing pain relief.
Aspirin on the other hand belongs to a group of drugs called salicylates. It is a Non-steroidal anti-inflammatory drug (NSAID), which works by blocking the production of certain natural substances –prostaglandins, that cause fever, and pain.
Meanwhile, diphenhydramine belongs to a group of drugs called Histamine H1 Antagonist. It is the antihistamine component of Excedrin Pm and works by blocking the actions of histamines and symptoms of allergies, but it is also responsible for the sleepy and drowsy feeling you get after taking the medication. Because of this drowsy feeling, Excedrin Pm is recommended to be taken once a day, only at bedtime, with a full glass of water.
HOW TO USE EXCEDRIN PM
It is an oral drug and can be taken without food, but in case you experience stomach upset when you take it without food, you may take it with food or milk, or as directed by your doctor.
