Oral contraceptives such as Yaz may increase your long-term risk of developing liver tumors and your short-term risk of heart attack, stroke, and blood clots while reducing your overall risk of ovarian, endometrial, and colorectal cancers. Some data suggest a little to no increase in the risk of breast and cervical cancer; however, the risk is generally associated with current use and diminishes once someone stops taking the pill.
As with all prescription medications, be sure to inform the prescribing doctor about any medical conditions you have been previously diagnosed with and any medications or supplements you currently take before using Yaz. The hormones in Yaz can interact with other forms of medication, causing potentially serious side effects. In addition, let your doctor know if you are pregnant or plan on becoming pregnant before starting treatment with this medication.
