Why Do Antidepressants Cause Sweating?

Antidepressants on the other hand do not cause sweating. Rather, there is a condition called hyperhidrosis which can be caused by certain antidepressants and anti-psychotics. This occurs because of an overactive sympathetic nervous system and blood vessel constriction (vasoconstriction).
