Warnings
Black Box Warnings
The drug should be administered under the supervision of an experienced cancer chemotherapy physician in a facility equipped to diagnose and manage complications
The drug is contraindicated in patients with solid tumor who have baseline neutrophil counts <1500 cells/m³ and in patients with AIDS-related Kaposi sarcoma who have baseline neutrophil counts <1000 cells/m³; perform frequent peripheral blood counts to monitor for occurrence of bone marrow suppression, primarily neutropenia, which may result in infection
Fatal anaphylaxis and severe hypersensitivity reactions characterized by dyspnea and hypotension requiring treatment, angioedema, and generalized urticaria have occurred in patients despite premedication
Pretreat all patients with corticosteroids, diphenhydramine, and H2 antagonists
Do not rechallenge patients who experience severe hypersensitivity reactions to the drug
Contraindications
Patients with solid tumors or patients with AIDS-related Kaposi’s sarcoma with baseline neutrophil counts of <1,500 cells/mm3
Documented hypersensitivity to drug or excipients
Cautions
All patients should be pretreated with corticosteroids, diphenhydramine, and H2 antagonists; fatal reactions have occurred in patients despite premedication; patients who experience severe hypersensitivity reactions to paclitaxel should not be rechallenged with the drug
Bone marrow suppression (primarily neutropenia) is dose-dependent and is dose-limiting toxicity; should not be administered to patients with baseline neutrophil counts <1,500 cells/mm3 (<1,000 cells/mm3 for patients with KS); frequent monitoring of blood counts should be instituted during paclitaxel treatment; patients should not be re-treated with subsequent cycles of paclitaxel until neutrophils recover to a level >1,500 cells/mm3 (>1,000 cells/mm3 for patients with KS) and platelets recover to a level >100,000 cells/mm3
Severe conduction abnormalities have been documented in <1% of patients during paclitaxel therapy and in some cases requiring pacemaker placement; if patients develop significant conduction abnormalities during paclitaxel infusion, appropriate therapy should be administered and continuous cardiac monitoring should be performed during subsequent therapy with paclitaxel
Contact of the undiluted concentrate with plasticized polyvinyl chloride (PVC) equipment or devices used to prepare solutions for infusion is not recommended; in order to minimize patient exposure to the plasticizer DEHP [di-(2-ethylhexyl)phthalate], which may be leached from PVC infusion bags or sets, diluted paclitaxel solutions should preferably be stored in bottles (glass, polypropylene) or plastic bags (polypropylene, polyolefin) and administered through polyethylene-lined administration sets
Paclitaxel should be administered through an in-line filter with a microporous membrane not greater than 0.22 microns; use of filter devices such as IVEX-2R filters which incorporate short inlet and outlet PVC-coated tubing has not resulted in significant leaching of DEHP
May increase the risk of cardiac dysfunction if received in conjunction with trastuzumab or anthracyclines
Pregnancy & Lactation
Pregnancy Category: D
Lactation: not known if excreted in breast milk, do not nurse
Pregnancy Categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk. C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done. D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk. X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist. NA: Information not available.Pharmacology

IV Administration
Irritant
Mfr recommends administration over 1-24 hr
Administer taxane derivatives before platinum derivatives (cisplatin, carboplatin) in sequential infusions to limit myelosuppression and to enhance efficacy
Administer corticosteroids, H1-antagonists, H2 antagonists, prior to paclitaxel administration to minimize potential for anaphylaxis
Non-PVC tubing should be used to minimize leaching
Contact of undiluted concentrate with plasticized PVC equipment or devices is not recommended
Administer through IV tubing containing an in-line (0.22 micron) filter
Should be dispensed in either glass or Excel/PAB
