One must be very careful with [finastseride], as it’s sometimes prescribed quickly, without always informing patients of its risks, or of what to do in the event of sexual problems. So I urge you, if you’re about to take finasteride, or if you’re already doing so, contact your dermatologist or the doctor who prescribed if for you so you can benefit from regular monitoring… Also, if symptoms appear, the right decisions can be made, to avoid sexual problems that could last longer.
