Triphasil is a brand-name oral contraceptive used to prevent pregnancy. It is a triphasic birth control pill, which means the hormone levels change throughout the menstrual cycle to more closely mimic the body’s natural hormone patterns. It contains a combination of ethinyl estradiol and levonorgestrel, a type of progestin (progestogen).
Triphasil is taken daily and is most effective when used consistently. It does not protect against sexually transmitted diseases. It may also help regulate menstrual periods, reduce breakthrough bleeding, and improve symptoms such as heavy or painful periods.
