Joint pain, discomfort, swelling, and stiffness from osteoarthritis (arthritis caused by a breakdown of the lining of the joints) and rheumatoid arthritis are all symptoms that may be treated with prescription ibuprofen (arthritis caused by swelling of the lining of the joints). It is also used to treat moderate discomfort, such as that experienced during menstruation (pain that happens before or during a menstrual period). Ibuprofen, available without a prescription, may be used to lower fever and alleviate the pain associated with a variety of common ailments, including headaches, muscular pains, arthritis, menstruation, the flu, tooth pain, and back pain. Ibuprofen is categorized as a nonsteroidal anti-inflammatory drug (NSAID). The pain-inducing, fever-raising, inflammation-causing chemical produced by your body is blocked, and you experience relief.
