Are there any medication to counter the lowered libido from taking finasteride?

Yes: Finasteride does cause sexual dysfunction. If this occurs, then oral medications such as viagra, (sildenafil) cialis, etc. Can be beneficial. If these fail, the penile injections or a vauum erection deveice may be needed.

No: You can talk to your doctor about taking the medication intermittently. The libido will return when you have been off of the drug for a few days.
