If you've been using Indocin for 20-yrs without side effects you have pretty good evidence of its safety--especially with the relatively small doses which I assume you are using.

Indocin's primary potential is for stomach upset/ulcer formation. That potential increases with your age but your doc can give you an effective med which protects the stomach, allowing you to continue the benefit of the Indocin.

A review of medical literature this morning shows that Indocin is still the recommended med for CPH.

The newer formulations of this class of drugs (U.S.--Vioxx and Celebrex, etc.) may have reduced some of the toxic properties of indocin but with the consequence of being less effective for some of the disorders for which indocin was the drug of choice.

I used indocin for many years for an auto immune disorder with great success but then my gut started to rebel and I had to change to Celebrex. An almost useless change!

From what you have told us, it sounds like you have an effective combination working with, it appears, no new options. If you and your doc have no evidence of harm......
