Combined birth control pills contain the hormones estrogen and progestin that stop ovulation and make the lining of the uterus thinner.
When used consistently and correctly, fewer than 1 out of 100 women will become pregnant over the course of one year. With typical use, 8 women out of 100 will become pregnant.
A prescription from a healthcare provider is required to obtain combined birth control pills. To obtain a prescription for birth control pills, call University Health Services (UHS) at (512) 471-4955 to make an appointment with the Women's Health Clinic.
