Good morning. I was on clofazimine for 18 months in place of Rifampin, due to adverse kidney damage from the Rifampin. I have been MAC free for 2 years now thanks to clofazimine. It was round 2 for getting rid of MAC and the clofazimine worked. I converted in 2 months. I cant say enough about clofazimine. I did get a light tan, which was fine. Initially I was petrified to start it as I had looked online at what people looked like while on it and it was awful. Later I realized those unfortunate individuals were on clofazimine due to leopracy which has a completely different outcome so I gathered my senses and started the regimen and I am so glad I did. Please dont be discouraged by people saying you will turn orange when i think that is quite an exaggeration when you will actually look like you live in Florida and hit the tennis courts every day! Also the tanning comes in gradually. You wont even notice it for some time if you notice it much at all. Best to you!
