Elevated prolactin is a lesser known side effect of taking finasteride. P5P, a b vitamin, is capable of lowering prolactin levels and I experienced firsthand what I believe is a reversal in sides from this specific supplement. For about a week prior, I’d had literally no orgasm or a very minor one but with normal ejaculations. From starting it last night at 200 mg and taking 100 mg this morning, I can confidently say my sensitivity has majorly come back— about 70% in just one day, and I feel likely will come back to 100 very soon.

Although I will say, this side did occur before for a couple days and come back to 100 on its own once before during my ~1 month of treatment, and it has been a very tumultuous month emotionally on top of the new treatments.

Just wanted to post this as something to try, as it’s incredibly cheap and might help some of you out there feeling you just need to deal with sides like this. At around $15 for 400 100mg pills it’s worth a shot.

Edit:

It’s been about 3 more days and I can confidently say I’m back to 100.
