I had been taking 1mg Finasteride per day orally, but i experienced some unwanted side effects.
I tried making a topical mixture of minoxidil and Finasteride. I crushed 60mg of Finasteride into 60ml of Minoxidil. I was applying this once per day.
However, I found this to be less effective than taking oral Finasteride. I found some hair loss, and i'm not sure if this oral solution helped at all. On the positive side, there were no side effects either! (I have read that many people have benefitted from topical Finasteride).
However, since then, i have been taking 0.5mg of Finasteride per day orally, and this seems to be effective for me, with no side effects.
Then I purchased a supply of 5mg Finasteride tablets, and divide each into 4. I take one of those every other day.
So at the moment I am taking 1.25mg every other day. I don't notice any side effects like this either.
Not sure if that helps you, but good luck.
