Ibuprofen is an 
NSAID used to treat 
fever and 
pain from 
arthritis, 
menstrual cramps, and muscular aches. It works by reducing inflammation. Ibuprofen is a generic medication, and is available both over-the-counter and by prescription depending on the strength. Prescription 
Motrin had the same active ingredient, but has been discontinued. Over-the-counter brands include 
Advil and 
Motrin IB. Ibuprofen should be used only when needed as it may increase 
risk of stroke or 
heart attack and long term use can cause stomach 
bleeding and ulcers.
