When does spiro start to work?

Hi everyone.

I deal with some hormonal acne around me chin/jaw and my dermatologist prescribed me spiro to treat it. It is not the WORST acne in the world, and it mostly is flesh colored bumps with the occasional red spots, but I am ready to get rid of it all together.

I have been on 100mgs since September, and I have not noticed a difference. I just started tretinoin again, so I am hoping that helps with some of the progress.

I heard that it is supposed to start working 3 months in, and I am starting to become discouraged. Please tell me there is still a chance for it to work.

I also just got a refill and my pills seem to be different. The first time around, they were orange and smelled minty. Now they are white and oval, and the manufacturer Pfizer makes them. I am hoping this makes a difference.
