Yaz (drospirenone/ethinyl estradiol) is a contraceptive oral medication that is prescribed primarily to prevent pregnancy, but may also be used to control acne in some cases. Most patients tolerate the drug well showing no side effects at all. Many clinical trials have been done to ensure the safety of the drug and to gauge its effectiveness.
Mild side effects that have been reported with the use of Yaz include nausea, and an increase of appetite (which may lead to weight gain), decreased sex drive, headaches, vaginal discharge, spot bleeding between periods, and yeast infections.
Severe side effects are rare. Some severe side effects requiring medical attention may include blood clots in the lungs or legs. If you experience leg cramps, swelling, pain, or weakness in the legs, chest pain, shortness of breath, or are coughing up blood, see your doctor immediately. These could indicate blood clots. Any changes in vision, or severe headaches should also be reported. Sharp chest pain or heaviness in the chest could be signs of a heart attack and should be evaluated by a health professional. Migraines, high blood pressure, high cholesterol, unusual vaginal bleeding that does not improve over time, and allergic reactions to Yaz, must also be evaluated by a physician. While very few of these symptoms are reported with Yaz, they are serious conditions and may or may not be associated with the use of the drug. Consult your health care provider if you experience any unusual side effects while taking Yaz.
