Alternative, non-oral methods of birth control should be used, or add another method of birth control (such as condoms) to the oral contraceptive for 4 weeks after starting tirzepatide and for 4 weeks each time after the dose of tirzepatide is increased to avoid unintended pregnancy. Talk to your gynecologist or other healthcare professional if you have any questions or concerns, and for help in selecting an effective method of birth control that is best for you.
