Consult your doctor for more details. It is not known whether this drug passes into breast milk. Because of the potential risk to the infant, breast-feeding while using this drug is not recommended.

DRUG INTERACTIONS: Tell your doctor or pharmacist of all prescription and nonprescription drugs you may use, especially of: azole antifungals (e.g., itraconazole,), thioguanine, acetaminophen, drugs that can cause seizures (e.g., bupropion), drugs that can increase seizure risk (e.g., phenothiazines such as chlorpromazine), other drugs which affect the bone marrow/immune system (e.g., other anti-cancer drugs, cyclosporine). Check your prescription and nonprescription labels carefully for acetaminophen-containing products. If needed, use the products cautiously 3 days before and during therapy with busulfan. Acetaminophen may increase busulfan blood levels and side effects. If acetaminophen is used, do not exceed recommended daily doses.
