Indomethacin is used to relieve moderate to severe pain, tenderness, swelling, and stiffness caused by osteoarthritis (arthritis caused by a breakdown of the lining of the joints), rheumatoid arthritis (arthritis caused by swelling of the lining of the joints), and ankylosing spondylitis (arthritis that mainly affects the spine). Indomethacin is also used to treat pain in the shoulder caused by bursitis (inflammation of a fluid-filled sac in the shoulder joint) and tendinitis (inflammation of the tissue that connects muscle to bone). Indomethacin immediate-release capsules, suspension (liquid) and suppositories are also used to treat acute gouty arthritis (attacks of severe joint pain and swelling caused by a bu
ild-up of certain substances in the joints). Indomethacin is in a class of medications called NSAIDs. It works by stopping the body’s production of a substance that causes pain, fever, and inflammation.
Indomethacin comes as a capsule, an extended-release (long-acting) capsule, and a suspension to take by mouth and as a suppository to be used rectally. Indomethacin capsules and liquid usually are taken two to four times a day. Indomethacin suppositories usually are used two to four times daily. Extended-release capsules are usually taken one or two times a day. Indomethacin capsules, extended-release capsules, and suspension should be taken with food, immediately after meals, or with antacids. Take indomethacin at around the same times every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take indomethacin exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Swallow the extended-release capsules whole; do not split, chew, or crush them.
Shake the suspension well before each use to mix the medication evenly.
Your doctor may change the dose of your medication during your treatment. In some cases, your doctor may start you on a low dose of indomethacin and gradually increase your dose, not more often than once a week. In other cases, your doctor may start you on an average dose of indomethacin and decrease your dose once your symptoms are controlled. Follow these directions carefully and ask your doctor or pharmacist if you have any questions.
