Thiotepa is an alkylating drug sold in the U.S. under 2 brand and generic names, for adenocarcinoma, urinary bladder neoplasms and breast neoplasms. Below: what the FDA label says, every product that contains it, what the pills look like, and its recall record.
From the FDA label for Tepylute (application NDA216984). Other thiotepa products — different forms, different strengths — are dosed differently. Follow the label for the one you were prescribed.
The recommended dose of TEPYLUTE for treatment of adenocarcinoma of the breast or ovary is 0.3 mg/kg to 0.4 mg/kg intravenously. ( 2.1 ) See full prescribing information for preparation instructions. ( 2.2 ) 2.1 Recommended Dosage Adenocarcinoma of the Breast or Ovary The recommended dose of TEPYLUTE for treatment of adenocarcinoma of the breast or ovary is 0.3 mg/kg to 0.4 mg/kg intravenously. Doses should be given at 1 to 4 week intervals. Initially the higher dose in the given range is commonly administered. The maintenance dose should be adjusted weekly on the basis of pretreatment control blood counts and subsequent blood counts. Maintenance doses should not be administered more frequently than weekly. 2.2 Preparation Instructions TEPYLUTE is a hazardous drug. Follow applicable special handling and disposal procedures 1 . Use aseptic technique to prepare TEPYLUTE. Dilution in the infusion bag Remove vial from refrigerated conditions 1 hour prior to dilution. Dilute the solution in an appropriate volume of 0.9% Sodium Chloride Injection to obtain a final TEPYLUTE concentration between 0.5 mg/mL and 1 mg/mL. Use a 16G needle with a Luer-lock syringe to dilute the solution. Use the diluted TEPYLUTE infusion solution immediately. If the solution is not used immediately, store refrigerated at 2°C to 8°C (36°F to 46°F) for up to 24 hours, or at room temperature 25°C (77°F) for…
The following clinically significant adverse reactions are described elsewhere in other sections of the label: Myelosuppression [ see Warnings and Precautions ( 5.1 ) ] Infection [ see Warnings and Precautions ( 5.1 ) ] Hypersensitivity [ see Warnings and Precautions ( 5.2 ) ] Cutaneous Toxicity [ see Warnings and Precautions ( 5.3 ) ] Hepatic Veno-Occlusive Disease [ see Warnings and Precautions ( 5.5 ) ] Central Nervous System Toxicity [ see Warnings and Precautions ( 5.6 ) ] Carcinogenicity [ see Warnings and Precautions ( 5.7 ) ] The most common adverse reactions (incidence greater than 10%) are neutropenia, anemia, thrombocytopenia, elevated alanine aminotransferase, elevated aspartate aminotransferase, elevated bilirubin, mucositis, cytomegalovirus infection, hemorrhage, diarrhea, hematuria and rash. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Shorla Oncology at 844-9-SHORLA or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch . 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared with rates in the clinical trials of another drug and may not reflect the rates observed in practice. Adverse Reactions with Treatment of adenocarcinoma of the breast and adenocarcinoma of the ovary Gastrointestinal: Nausea, vomiting, abdominal…

Effect of Cytochrome CYP3A Inhibitors and Inducers In vitro studies suggest that thiotepa is metabolized by CYP3A4 and CYP2B6 to its active metabolite TEPA. Avoid coadministration of strong CYP3A4 inhibitors (e.g., itraconazole, clarithromycin, ritonavir) and strong CYP3A4 inducers (e.g., rifampin, phenytoin) with thiotepa due to the potential effects on efficacy and toxicity [see Clinical Pharmacology ( 12.3 )]. Consider alternative medications with no or minimal potential to inhibit or induce CYP3A4. If concomitant use of strong CYP3A4 modulators cannot be avoided, closely monitor for adverse drug reactions. 7.2 Effect of TEPYLUTE on Cytochrome CYP2B6 Substrates In vitro studies suggest that thiotepa inhibits CYP2B6. Thiotepa may increase the exposure of drugs that are substrates of CYP2B6 in patients; however, the clinical relevance of this in vitro interaction is unknown [see Clinical Pharmacology ( 12.3 )] . The administration of thiotepa with cyclophosphamide in patients reduces the conversion of cyclophosphamide to the active metabolite, 4-hydroxycyclophosphamide; the effect appears sequence dependent with a greater reduction in the conversion to 4-hydroxycyclophosphamide when thiotepa is administered 1.5 hours prior to the intravenous administration of cyclophosphamide compared to administration of thiotepa after intravenous cyclophosphamide [see Clinical Pharmacology…
