Lorlatinib may interfere with the action of hormonal contraceptives (birth control pills, patches, rings, implants, or injections), so you should not use these as your only method of birth control during your treatment. You must use a non-hormonal birth control such as a barrier method (device that blocks sperm from entering the uterus such as a condom or a diaphragm). Ask your doctor to help you choose a method of birth control that will work for you. If you are female, you will need to take a pregnancy test before you start treatment and should use non-hormonal birth control to prevent pregnancy during your treatment and for 6 months after your final dose. If you are male, you and your female partner should use birth control during your treatment and for 3 months after your final dose. Talk to your doctor about birth control methods that you can use during your treatment. If you or your partner become pregnant while taking lorlatinib, call your doctor immediately. Lorlatinib may harm the fetus.
- tell your doctor if you are breast-feeding. You should not breast-feed while you are taking lorlatinib and for 7 days after your final dose.
