I have had mg for over 6 years, on 10mg of prednisone daily, can't seem to lower the dose without effects. So here's an odd question for all of you. I started taking cimetidine ( generic Tagamet) because the prednisone has really done a number on my stomach, and I seem to improve. Normally by the end of the day, my eyelid would drop, and my facial muscles were noticeable. So I started doing some reasearch, and I came up with nothing except for a site for vets, vetmeds, that suggested prescribing it to dogs with mg. So is there anyone who could think of a reason why this may help, or willing to try it, to see, if it's something as simple as taking 200mg of cimetidine a day, to reduce symptoms. Maybe it's a fluke, but if there's something to it, more research needs to be done.
