Ibuprofen – Ibuprofen falls into the class of drugs known as NSAIDs (nonsteroidal anti-inflammatory drugs). Sold under brand names including Motrin or Advil, it's used to treat minor aches and pains and reduce fever. It may be prescribed in stronger doses. It comes in tablet form as well as in chewable tablets, liquid suspensions and concentrated liquid drops. People who take NSAIDs may have a higher heart attack or stroke risk than those who do not, according to the National Institutes of Health. The medication can also cause ulcers, bleeding or holes in the stomach and intestine for some people. The risk may be higher if you take NSAIDs for a long time, are older or in poor health, and have three or more alcoholic drinks per day.
