There is a study speaking of “sexual disinhibition” by pregabalin, which would be the opposite of side-effects of most pharmaceuticals to inhibit or degrade sexual function.
I’ve also seen studies of reduced libido with pregabalin or gabapentin, its precursor. Anyway, this is slightly interesting. I have pregabalin as a matter of fact, but I’ve only tried it on and off to treat other symptoms, and I can say if there are pro-sexual effects, they are not immediate, so I would have to take it more frequently to find out. Its immediate effect is rather to dampen sexual function or nerval stimulation.
It is just something to put on a list for consideration.
