Hi, MJ,
I've taken either Pilocarpine or Evoxac since 2002. Right now I'm on 30 mg Pilocarpine/day, which is 6 of the 5 mg tablets.
I don't have diarrhea from the Pilocarpine.
Even with this high dose I still have dryness, and use eye drops and run the humidifier in the winter. For my dry mouth I use Xylimelts during the day if I'm going to be talking, like when I play bridge for two hours.
I'm sorry pilocarpine is giving you this side effect. We are all so different, it is hard to know what will work, what will have side effects, etc. Trial and error.
Keep us posted, MJ, Elaine
