Pregnancy: Tell the doctor if the patient thinks she is (or might become) pregnant. The doctor will normally advise to stop taking Irbegen before becoming pregnant or as soon as the patient knows she is pregnant and will advise to take another medicine instead of Irbegen. Irbegen is not recommended in early pregnancy, and must not be taken when more than 3 months pregnant, as it may cause serious harm to the baby if used after the third month of pregnancy.
Breast-feeding: Tell the doctor if the patient is breast-feeding or about to start breast-feeding. Irbegen is not recommended for mothers who are breast-feeding, and the doctor may choose another treatment if the patient wishes to breast-feed, especially if the baby is newborn, or was born prematurely.
