Switching From Propecia to Proscar

I have taken Propecia for 4 plus years with some success. I’d like to take proscar but don’t know how to go about it. Could you help? thanks

Proscar is the same drug as Propecia, just in a higher dosage per tablet. Propecia contains 1 mg of finasteride per tablet, and Proscar contains 5 mg of finasteride per tablet. When Merck did their studies on hair loss, it was determined that 1mg of finasteride was just as effective as 5 mg or even 10 mg of finasteride, but that taking only 1/2 mg of finasteride was 20% less effective.

So the only ‘benefit’ to taking more than the recommended 1 mg of finasteride in each Propecia pill, is a higher chance of side effects. If you want to take Proscar because it is more cost effective, you can split the pill into fourths. Splitting into fifths is more difficult and you tend to lose some of the pill in the cutting process. The doctor who prescribed Propecia for you, can prescribe Proscar for you.
