I had a noticeable headache prior to taking my 75 mg er indomethacin capsule. now it is going away. i've noticed this in the past.

Indometha-analgesic: Whatever reason you are taking indomethacin because it is an analgesic it will receive the other pains in addition to the pain for which you are taking. For example if you taking it for gout or rheumatoid arthritis, in addition to receiving of the joint pains it may help to take other sources of pain you may have like head ache, eye pain ,sinus pain ,tooth ache etc.
