"i am extremely satisfied with this medication. i took it for 5 months, and at my peak i was prescribed 40mg twice a day. it took about 3.5 months to start noticing results. i have now been off it for 3 weeks and wow! my skin is 100% clear. i&#039;ve had acne since i was a teen and after failing other options such as antibiotics, i was placed on claravis. you will have chapped lips. i had to apply aquaphor (really good chapstick) every 15 minutes. other side effects i had were nosebleeds, dry skin, eczema, rashes on my hands and arms, very sore muscles, sore chest, and any scrapes i got took absolutely forever to heal. i felt sluggish, sort of like i had the flu for 5 months. however, having clear skin was definitely worth it!"
