Toposar (etoposide) Disease Interactions
There are 2 disease interactions with Toposar (etoposide):
Antineoplastics (Includes Toposar) ↔ Infections
Severe Potential Hazard, High plausibility
Applies to: Infection - Bacterial/Fungal/Protozoal/Viral
Because of their cytotoxic effects on rapidly proliferating tissues, antineoplastic agents frequently can, to varying extent, induce myelosuppression. The use of these drugs 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 antineoplastic therapy. Close clinical monitoring of hematopoietic function is recommended.

Etoposide (Includes Toposar) ↔ Myelosuppression
Severe Potential Hazard, High plausibility
Applies to: Bone Marrow Depression/Low Blood Counts, Fever, Bleeding
Etoposide induces dose-related myelosuppression. Leukopenia, thrombocytopenia, and anemia have been reported during etoposide therapy. Patients should be instructed to immediately report any signs or symptoms suggesting bone marrow suppression such as fever, sore throat, local infection, or bleeding. Therapy should be administered cautiously in patients whose bone marrow reserve may be severely depressed and should be withheld if an absolute neutrophil counts fall below 500/mm3 and/or platelet counts fall below 50,000/mm3. Clinical monitoring of hematopoetic function is recommended. Periodic complete blood counts should be done during the course of etoposide treatment and it should be performed prior to each cycle of therapy and at appropriate intervals during and after therapy. At least one determination should be done prior to each dose.

Drug Interaction Classification
The classifications below are a general guideline only. It is difficult to determine the relevance of a particular drug interaction to any individual given the large number of variables.
|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.|
