Midol PM

Midol PM is an over the counter medication used to treat headaches, minor aches and pain, and difficulty sleeping due to premenstrual or menstrual periods.

It is a single product containing 2 ingredients: acetaminophen and diphenhydramine. Acetaminophen belongs to a group of drugs called analgesics, which is thought to work by blocking pain signals from reaching the brain. 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 or without food. 

Common side effects of Midol PM includes nausea, vomiting, and dizziness. Midol PM can also cause drowsiness. Do not drive or operate heavy machinery until you know how Midol PM affects you.
