Ethinyl estradiol / levonorgestrel
"I've used Aviane for approx. 14 years, I'm 43 now.  My doctor recommended Aviane because it had a low hormone level.  I never gained weight and my period have for the most part always been light.  The only side effect that I've experienced is Melasma (dark spots on face).  I've recently tried to get off of this birth control but I experienced immediate weight gain. It could be attributed to my age...I don't know.   Since I'm single now am not sexually active right now I'm going to stop using Aviane to see if my dark spot problem clears up."
