High sex drive and progressive ineffectiveness while on finasteride

After 8 months on .25 mg finastride and 5% Minoxidil, I notice an increase in my sex drive, watery semen and nipple tenderness. I masterbate 4-5x per day, double my usual count. I have been taking Finastride since 2014 (1.25 mg) but reduced the dosage due to sides. Sometimes I feel Finastride effects me emotionally. I feel very irritated, loss of focus, minor speech problems and experience depression, all of which I have no proof if it is related to the Finastride. My hair has gotten much thinner in the last year too. Is it recomended to stay on this medication with these side effects or what I percieve as side effects? Should I stay on it for a whole year to see if the side effects go away? I was in much bad shape before I decided to take a lower dose and now I feel much better but I am worried about my health because I am not as mentally sharp as I used to be.

You are already taking 1/4 of the dose of finasteride which is only 50% as effective of the full dose.  I doubt that you will see a better result of the finasteride by dropping the dose further.  I have a few patients that report an increased sex drive on the drug but few complain about it. Maybe your sex drive will decrease with a lower dose. I think that you should you go back to your doctor and ask your doctor if this is the drug approach for you. It sounds to me like you have too many side effect which you are ascribing to the drug finasteride, a good reason to stop it.
