Drug Interaction Report

MONITOR: The concomitant use of bone marrow depressants and sodium phosphate P-32 may have additive myelosuppressive effects.

MANAGEMENT: Patients should be monitored for excessive bone marrow suppression during treatment with sodium phosphate P-32. Sodium phosphate P-32 should not be used as part of a sequential treatment with a chemotherapeutic agent. Dose reductions of the other bone marrow depressants may be necessary. The manufacturer's labeling should be consulted for more specific recommendations for each agent involved. Patients should be advised to contact their physician if they develop signs and symptoms of myelosuppression such as pallor, dizziness, fatigue, lethargy, fainting, easy bruising or bleeding, or signs of infection such as fever, chills, sore throat, body aches, and other influenza-like symptoms.

GENERALLY AVOID: Alcohol may potentiate some of the pharmacologic effects of CNS-active agents. Use in combination may result in additive central nervous system depression and/or impairment of judgment, thinking, and psychomotor skills.

MANAGEMENT: Patients receiving CNS-active agents should be warned of this interaction and advised to avoid or limit consumption of alcohol. Ambulatory patients should be counseled to avoid hazardous activities requiring complete mental alertness and motor coordination until they know how these agents affect them, and to notify their physician if they experience excessive or prolonged CNS effects that interfere with their normal activities.
