I started taking claravis about a year ago at age 14 for severe acne. I was on it for about 5 months. Started at 80 mg per day, my back and my knees started hurting so badly I could barely get out of bed. The doctor then changed it to 40 mg per day. I have not grown in about a year - since I started taking the claravis. I am wondering if the pain was my growth plates closing. Did anyone have a similar experience?
