Im 10 days away from finishing my 5th month on finasteride and have not seen any benifit yet. I still lose over 150 in the shower a day, just like the way it was b4 treatment. And the worst thing is hat my acne is just horrible and I need to take some meds I think. I cant control it, ive been trying for 6 months. I was wondering if taking antibiotics, Erythromycin specificlly, for my acne affect Propecia effectivness at all? Does anyone else take any antibiotics for acne and is on finasteride? I shoulda started taking antibiotics a while ago but i didnt want to for that reason, but now i dont have a choice. Ive noticed how some people also say that when they took antibiotics for there acne, it stopped there hairloss, which is kinda weird, but after they stopped the antibiotics they shed like crazy.
