If you are a woman who can get pregnant, your doctor may do tests before you start using lorlatinib to make sure you are not pregnant. Birth control pills may not work as well to prevent pregnancy when used with lorlatinib. Use another form of birth control (eg, condoms, spermicide) along with your pills. Female patients should use effective birth control during treatment and for at least 6 months after the last dose. Male patients who have female partners should use effective birth control during treatment and for at least 3 months after the last dose.
