What is indomethacin?
Indomethacin is in a group of drugs called nonsteroidal anti-inflammatory drugs
(NSAIDs). Indomethacin works by reducing hormones that cause inflammation and pain in the
body.
Indomethacin is used to treat pain or inflammation caused by many conditions such as
arthritis, gout, ankylosing spondylitis, bursitis, or tendinitis.
Indomethacin may also be used for other purposes not listed in this medication guide.

What should I discuss with my healthcare provider before taking indomethacin?
Taking an NSAID can increase your risk of life-threatening heart or circulation problems,
including heart attack or stroke. This risk will increase the longer you use an NSAID. Do not
use this medicine just before or after having heart bypass surgery (also called coronary artery
bypass graft, or CABG).
NSAIDs can also increase your risk of serious effects on the stomach or intestines,
including bleeding or perforation (forming of a hole). These conditions can be fatal and
gastrointestinal effects can occur without warning at any time while you are taking an NSAID.
Older adults may have an even greater risk of these serious gastrointestinal side effects.
Do not use this medication if you are allergic to indomethacin, or if you have a
history of allergic reaction to aspirin or other NSAIDs.
Before taking indomethacin tell your doctor if you are allergic to any drugs, or if you
have:
-
a history of heart attack, stroke, or blood clot;
-
heart disease, congestive heart failure, high blood
pressure;
-
a history of stomach ulcers or bleeding;
-
liver or kidney disease,
-
a seizure disorder such as epilepsy;
-
asthma;
-

If you have any of these conditions, you may need a dose adjustment

with a regular table spoon. If you do not have a dose-measuring device, ask your pharmacist for
one.
