"i&#039;d like to say that claravis is just amazing but i&#039;m having mixed feelings now, this will be third session on this medication. i&#039;m 19 yrs old and my weight is close to 100 pds, i started this medication when i was 17, and then i was taking 80 mg a day and i felt fine and it was a complete life change for me to have clear skin but then months later it returned...to make a long story short, the more i take this medication the more sick i feel, i&#039;ve developed acid reflex, muscle spasms, muscle aches and flushing skin."
