Thought I'd refresh a couple side effect questions...
There are meds that act at acetylcholine receptors that reduce sweating, but those meds have side effects including drying the mouth and drowsiness. The mouth effects can increase dental caries.
Usually sweating goes away after tolerance develops... but the best thing in my opinion is to try to slightly lower your dose. Doses of buprenorphine that are higher than necessary often cause sweating and constipation.
Sweating - How to help it?
Does Suboxone hurt teeth? Why does the film taste bad? Am I high on Suboxone? If you have side effects to buprenorphine, discuss them here.
