Can gabapentin cause excessive sweaty feet?

Would be very rare: Sweating is not listed as a side effect of gabapentin. Gabapentin has actually been shown to reduce sweating in cases where excessive sweating is caused by nerve damage, or from high anxiety, However, I always say that anyone can get any side effect from any medication. When it comes to human beings, practically anything is at least remotely possible.

Potentially: Increased sweating occurs in 0.1% to 1% of people taking Gabapentin. REF: https://www.drugs.com/sfx/gabapentin-side-effects.html
