hi @Rrrr- I'm doing fine with the Famvir. Can't say that's it's a miraculous drug for me so far, but I'm tolerating it fine. I'm definitely better than I was when I started it, but again, I don't know if that's not just a normal cycle in the disease.
As far as the antacids, I don't know if we CAN, but I DO. My docs know I'm on famotadine as part of a mast cell cocktail and none of them have said not to take it or mentioned any concerns about it.
Good luck to you as you start it. What dose are you using?
