Ibuprofen belongs to the class of medications known as nonsteroidal anti-inflammatory drugs (NSAIDs). It is used to treat fever and mild to moderate pain caused by inflammation. It can be used to relieve pain and inflammation associated with arthritis, menstrual cramps, sprains, strains, backache, headaches, migraine, muscular aches and pain, sore throat, cold and flu, and dental pain.
In children under 12, ibuprofen is used for fever and pain due to colds, sore throat, immunization, and earache. It is believed to work by stopping the production of prostaglandins, which cause inflammation.
