CeeNU (lomustine) Disease Interactions

There are 5 disease interactions with CeeNU (lomustine):

Major

Lomustine (applies to CeeNU) pulmonary infiltrates/fibrosis

Major Potential Hazard, Moderate plausibility. Applicable conditions: Pulmonary Impairment

Pulmonary infiltrates and/or fibrosis have been reported during lomustine therapy. Toxicity occurred after 6 months of cumulative doses usually > 1100 mg/m2. Late reduction in pulmonary function, progressive fibrosis, and death have been noted. It is recommended to permanently discontinue therapy in patients diagnosed with pulmonary fibrosis. Therapy with lomustine should be administered cautiously in patients with preexisting pulmonary dysfunction. Pulmonary function studies prior to and during therapy are recommended.

Major

Nitrosoureas (applies to CeeNU) infections

Major Potential Hazard, High plausibility. Applicable conditions: Infection - Bacterial/Fungal/Protozoal/Viral

Nitrosoureas can induce delayed myelosuppression. The use of nitrosoureas may be contraindicated in patients with known infectious diseases. All patients should be instructed to immediately report any signs or symptoms suggesting infection such as fever, sore throat, or local infection during therapy with nitrosoureas. Close clinical monitoring of hematopoietic function is recommended.

Major

Nitrosoureas (applies to CeeNU) myelosuppression

Major Potential Hazard, High plausibility. Applicable conditions: Bone Marrow Depression/Low Blood Counts, Fever, Bleeding

Nitrosoureas induce delayed bone marrow suppression that is cumulative and dose-related. Thrombocytopenia is usually more severe than leukopenia. Anemia occurs less frequently and is less severe. Patients should be instructed to immediately report any signs or symptoms suggesting bone marrow suppression such as fever, sore throat, local infection, bleeding or symptoms of anemia. Therapy with nitrosoureas should be administered cautiously in patients with bone marrow suppression. Blood counts should be monitored at least six weeks after a dose and dosage adjustments made based on the nadir blood counts of the previous dose.

Moderate

Carmustine/lomustine- renal dysfunction

Moderate Potential Hazard, Moderate plausibility.

Renal abnormalities such as azotemia, and progressive decline in renal function have been reported after prolonged therapy with large doses of carmustine and lomustine. Lower total doses have also resulted in kidney damage. Therapy with carmustine or lomustine should be administered cautiously in patients with a history of or predisposition to renal dysfunction. Clinical monitoring of renal function is recommended.

Minor

Nitrosoureas (applies to CeeNU) hepatic dysfunction

Minor Potential Hazard, Low plausibility. Applicable conditions: Liver Disease

A reversible increase in liver transaminase, alkaline phosphatase, and bilirubin levels has been reported during therapy with nitrosoureas. Therapy with nitrosoureas should be administered cautiously in patients with a history of or predisposition to compromised hepatic function.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No interaction information available.
