WARNING: MYELOSUPPRESSION and PULMONARY TOXICITY

Myelosuppression

Carmustine causes suppression of marrow function (including thrombocytopenia and leukopenia), which may contribute to bleeding and overwhelming infections. [see Warnings and Precautions (5.1) and Adverse Reactions (6)]. Monitor blood counts weekly for at least 6 weeks after each dose. Adjust dosage based on nadir blood counts from the prior dose [see Dosage and Administration (2.1)].

Do not administer a repeat course of Carmustine until blood counts recover.

Pulmonary Toxicity

Carmustine causes dose-related pulmonary toxicity. Patients receiving greater than 1400 mg/m² cumulative dose are at significantly higher risk than those receiving less. Delayed pulmonary toxicity can occur years after treatment, and can result in death, particularly in patients treated in childhood [see Adverse Reactions (6) and Use in Specific Populations (8.4)].
