Patients are generally advised to call their doctor in case of fever, symptoms of infection or painful injection sites, as these may progress severely without adequate medical attention. It is advised to drink lots of fluids after treatment to prevent damage to the bladder and kidneys, typically 1.5 to 3.5 litres of water on the day of treatment and for several days after.
Caution should be exercised when administering ETOPOPHOS with drugs that are known to inhibit phosphatase activities (e.g., levamisole hydrochloride). High-dose cyclosporin A resulting in concentrations above 2000 ng/mL administered with oral etoposide has led to an 80% increase in etoposide exposure with a 38% decrease in total body clearance of etoposide compared to etoposide alone.
ETOPOPHOS (etoposide phosphate) for Injection is contraindicated in patients who have demonstrated a previous hypersensitivity to etoposide, etoposide phosphate, or any other component of the formulations.
