My 17 yr old was put on Yaz for PMS and acne. The PMS and acne got better, but after 4-5 mnths she was having anxiety so severe she could not go to school. Her gyn denied it could be the Yaz, so I took her to a family physician (woman) who agreed it could be the Yaz! The gyns lie, they are in bed with the pharmacuetical companies. If you suspect this pill is making you sick, go off!
