General information

Indometacin is a non-steroidal anti-inflammatory medication. It is prescribed to relieve inflammation, swelling and stiffness, and is an effective pain killer. It is of particular use in arthritic and rheumatic conditions, acute gout, and for broad-spectrum pain relief. Indometacin can also be used to reduce fever.

It does not cure the underlying condition responsible for pain, fever or inflammation, but keeps the symptoms under control.

Indometacin may irritate or even damage your stomach. To reduce this, it is advised to take it with food.

This risk increases the longer you take this medication, or if you are also taking corticosteroid medications such as prednisone, anticoagulants (blood thinning medication) such as warfarin, or if you smoke or consume alcohol while being treated with indometacin.

It has been reported that people who take non-steroidal anti-inflammatory medications (such as indometacin) may have a higher risk of having a heart attack or a stroke than those not taking it. This risk may be higher if you take these medications over a prolonged period of time. Tell your doctor if you have or have had heart disease, a heart attack, or a stroke.

How does Indometacin work?

Indometacin blocks the production of chemicals in the body that are responsible for pain, fever, swelling and inflammation.
