I'm 16 and a few years ago I was on acutane and it worked beautifully. Then I was diagnosed with Lupus and RA a year ago and after being on Prednisone, plaquenil, mehtotrexate and other meds my acne is back. I think my rheumatologist said something about how lupus can cause medications to work slowly...? Because it took a month for the prednisone to kick in the first time I started using it. Is this going to make my new acne medications work slower then they normally would?
