"i&#039;m on my 3rd month of claravis 40 mg. i take 2 tablets once a day. i have had acne since i was 9. i have tried every cream, pill prescribed by my doctor, and various facial treatments. claravis is the only thing that has ever worked for me. i am on month 3 and the only time i break out is at the end of the month when i start my period. the pills are worth the side effects. i do have chapped and bloody lips, vaseline is my best friend,and i have had back pain in my lower back since month 2 of claravis. i don&#039;t know if it&#039;s related to the pills, but i did notice several folks on the board had the same pains. still for a person that&#039;s had blackheads, whiteheads, scars, and pimples all over my body since i was a kid, it&#039;s totally worth it."
