Tepadina Disease Interactions

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.

Thiotepa is rapidly metabolized by the liver to a biologically active form. The pharmacokinetic disposition of thiotepa has not be evaluated in patients with hepatic dysfunction. The use of thiotepa may be contraindicated in patients with existing hepatic damage. If the need outweighs the risk, extreme caution should be exercised in administering thiotepa and therapy should be initiated at a reduced dosage. Clinical monitoring of hepatic function is recommended.

Thiotepa induces dose-related myelosuppression. Therapy with thiotepa should be withheld if a white blood cell count falls below 3000/mm3 or a platelet count falls below 150,000/mm3. If the need outweighs the risk, extreme caution should be exercised in administering thiotepa and therapy should be initiated at a reduced dosage. Patients should be instructed to immediately report any signs or symptoms suggesting bone marrow suppression such as fever, sore throat, local infection, or bleeding. Close clinical monitoring of hematopoietic function is recommended.

Approximately 25% of thiotepa is eliminated by the kidney and <2% is eliminated unchanged in the urine. The pharmacokinetic disposition of thiotepa has not be evaluated in patients with renal dysfunction. The use of thiotepa may be contraindicated in patients with existing renal dysfunction. If the need outweighs the risk, extreme caution should be exercised in administering thiotepa and therapy should be initiated at a reduced dosage. Clinical monitoring of renal function is recommended.
