What is this medication?

ALERT: WARNING
Bone marrow suppression:
Lomustine causes myelosuppression, including fatal myelosuppression. Myelosuppression is delayed, dose-related, and cumulative, occurring 4 to 6 weeks after drug administration and persisting for 1 to 2 weeks. Thrombocytopenia is generally more severe than leukopenia. Cumulative myelosuppression from lomustine is manifested by greater severity and longer duration of cytopenias. Monitor blood counts for at least 6 weeks after each dose. Do not give lomustine more frequently than every 6 weeks.

Medication error prevention:
Prescribe, dispense, and administer only enough capsules for one dose. Fatal toxicity occurs with overdosage of lomustine. Both health care provider and pharmacist should emphasize to the patient that only one dose of lomustine is taken every 6 weeks.

How does this medication work? 

GLEOSTINE/CEENU (Lomustine) inhibits DNA, RNA, and protein synthesis via alkylation and carbamylation of DNA and RNA but is cell cycle non-specific.

How should I take this medication? 

Oral: Take 130 mg/m2 as a single dose once every 6 weeks; reduce dose to 100 mg/m2 as a single dose once every 6 weeks in patients with compromised bone marrow function.

How to Take: Antiemetics are recommended to prevent nausea and vomiting, administering on an empty stomach may reduce the incidence of nausea and vomiting.  Varying strengths of capsules may be required to obtain necessary dose.

What should I watch for while using this medication?
