Hair loss prevention therapy using finasteride: There has recently been some publicity about persistent sexual side effects from the use of finasteride (e.g. Propecia, Proscar, Finasta, Finnicar) tablets. The reports correctly state that a small percentage of patients can get sexual side effects. What is most controversial about the reports is the suggestion that the side effects persist for long periods of time after stopping the medication.

In my 14 year experience of prescribing finasteride, I have never had a case of persistent side effects after stopping the tablet. Nor have any of my colleagues around the world who prescribe it frequently. They always resolve soon after stopping the tablet. In addition, the chance of side effects is dramatically reduced if the medication is prescribed 2-3 times per week instead of daily. This intermittent use of the finasteride medication is just as effective and removes almost all possibility of any patients having side effects.

The long term use of finasteride is the cornerstone of therapy designed to prevent or dramatically reduce further hair loss. It also reduces the need for future hair transplant surgery by stabilising the loss. Most patients get great benefit from the medication and I have over 4000 patients in my practice successfully taking it without side-effects.
