Side Effects of Finasteride


Dear Dr. Mohebi,

Dr., I had a question: say I would use proscar now and took it for a while, after how long based on studies is it possible to see adverse side effects, if any? The reason why I ask is because when I went and read the messages on the forums, I saw positive and negative feedbacks. One person used proscar for 7 years and saw nothing but great results. I would like to give it a shot and see if I am lucky, hopefully. Thank you! Have a great weekend,

finasterie side effects


The side effects of finasteride (Propecia/Proscar) could be seen anytime from right after starting it to months after starting finasteride. If you read the articles on adverse effects of finasteride you can clearly see that there is a small difference between the rates of side effects from the people who took placebos to the ones taking finasteride.

Let’s face it; you are prescribing a drug to a patient telling him that it works through altering your male hormones. What do you think the chances are that the patient will have problems with his sex drive?

The good news is that the side effects of finasteride are few and the most problematic one (decreased sex drive) is only seen in one out of a hundred patients. The other good news is that even if you are in that one percent category and you decide to continue using finasteride anyway, after one year of using finasteride the rate of side effects decreases to about the rate that was shown in people who only took a placebo.
