My pain specialist once told me it was okay to take Prozac with St. John's Wort, and it isn't, so just because a doctor tells you something doesn't mean it is always true. I would ask your pharmacist. He should know and if he doesn't seems he could look that up for you.
So much info now on meds and their relationship to supplements and homepathic remedies.
I'm on Nexium 40 mg. and all I take are Tums if I need anything for GERD. I also have to take Lortabs for the pain when I get it as it is the only thing that will help, but then I also have FMS (fibromyalgia).
Good luck and I hope your pharmacist will help you.
