TOXIC DEATHS, HEPATOTOXICITY, NEUTROPENIA, HYPERSENSITIVITY REACTIONS, and FLUID RETENTION
The incidence of treatment-related mortality associated with docetaxel therapy is increased in patients with abnormal liver function, in patients receiving higher doses, and in patients with non-small cell lung carcinoma and a history of prior treatment with platinum-based chemotherapy who receive docetaxel as a single agent at a dose of 100 mg/m² [see WARNINGS AND PRECAUTIONS]. DOCEFREZ should not be given to patients with bilirubin > upper limit of normal (ULN), or to patients with AST and/or ALT > 1.5 x ULN concomitant with alkaline phosphatase > 2.5 x ULN. Patients with elevations of bilirubin or abnormalities of transaminase concurrent with alkaline phosphatase are at increased risk for the development of grade 4 neutropenia, febrile neutropenia, infections, severe thrombocytopenia, severe stomatitis, severe skin toxicity, and toxic death. Patients with isolated elevations of transaminase > 1.5 x ULN also had a higher rate of febrile neutropenia grade 4 but did not have an increased incidence of toxic death. Bilirubin, AST or ALT, and alkaline phosphatase values should be obtained prior to each cycle of DOCEFREZ therapy [see WARNINGS AND PRECAUTIONS]. DOCEFREZ therapy should not be given to patients with neutrophil counts of < 1500 cells/mm³. In order to monitor the occurrence of neutropenia, which may be severe and result in infection, frequent blood cell counts should be performed on all patients receiving DOCEFREZ [see WARNINGS AND PRECAUTIONS]. Severe hypersensitivity reactions characterized by generalized rash/erythema, hypotension and/or bronchospasm, or very rarely fatal anaphylaxis, have been reported in patients who received a 3-day dexamethasone premedication. Hypersensitivity reactions require immediate discontinuation of the DOCEFREZ infusion and administration of appropriate therapy [see WARNINGS AND PRECAUTIONS]. DOCEFREZ must not be given to patients who have a history of severe hypersensitivity reactions to docetaxel or to other drugs formulated with polysorbate 80 [see CONTRAINDICATIONS]. Severe fluid retention occurred in 6.5% (6/92) of patients despite use of a 3-day dexamethasone premedication regimen. It was characterized by one or more of the following events: poorly tolerated peripheral edema, generalized edema, pleural effusion requiring urgent drainage, dyspnea at rest, cardiac tamponade, or pronounced abdominal distention (due to ascites) [see WARNINGS AND PRECAUTIONS].
Docetaxel is an antineoplastic agent belonging to the taxoid family. It is prepared by semisynthesis beginning with a precursor extracted from the renewable needle biomass of yew plants. The chemical name for docetaxel (anhydrous) is (2R,3S)-N-carboxy-3-phenylisoserine,N-tert-butyl ester, 13-ester with 5β-20epoxy-1,2α,4,7β,10β,13α-hexahydroxytax-11-en-9-one 4-acetate 2-benzoate. Docetaxel (anhydrous) has the following structural formula:
Docetaxel (anhydrous) is a white to almost-white powder with an empirical formula of C43H53NO14, and a molecular weight of 807.88. It is highly lipophilic and practically insoluble in water.
DOCEFREZ (Lyophilized Powder for Injection and Diluent)
DOCEFREZ (docetaxel) for injection is a sterile, lyophilized, non-pyrogenic, white powder and is available in single use vials containing 20 mg or 80 mg of docetaxel (anhydrous).
DOCEFREZ (docetaxel) for injection requires reconstitution with Diluent prior to use. For each 20 mg or 80 mg vial, a sterile, non-pyrogenic, single dose Diluent vial is co-packaged. The Diluent for DOCEFREZ (docetaxel) for injection contains 35.4 % w/w ethanol in polysorbate 80.
What are the possible side effects of docetaxel (Docefrez, Taxotere)?
Get emergency medical help if you have any of these signs of an allergic reaction: hives; difficult breathing; swelling of your face, lips, tongue, or throat.
Call your doctor at once if you have a serious side effect such as:
- extreme weakness;
- severe vomiting or diarrhea;
- fever, chills, body aches, flu symptoms, sores in your mouth and throat;
- pale skin, feeling light-headed or short of breath, rapid heart rate, trouble concentrating;
- easy bruising, unusual bleeding (nose, mouth, vagina, or rectum), purple or red pinpoint...
