Yaz is a 4th generation pill. Along with Liza and Lizelle, Yaz has the fewest side-effects if you are concerned about weight gain and water retention. They also help with acne, cycle control, lightening and shortening periods, and reduce menstrual cramps and risk of anemia.
Yaz and Lizelle have a lower estrogen dose than our other 4th generation pills. This can be good for those who may be sensitive to estrogen side-effects, and also lowers the risk of venous thrombosis. Yaz contains 28 pills instead of 21, for compliance.
