I've been taking generic Cellcept (Mycophenelate Moefitil), 500 mg, twice a day, for about six months now. The only side effects I've experienced were mild dizziness for a few hours after a dose. This lasted maybe a week, now no Ill effects at all. The warnings that accompany it are scary, but my dose is mild, transplant recipients take a higher dose, so I'm guessing that's where side effects are more likely.
