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

PACLITAXEL - INJECTION
(pack-lih-TAX-el)
COMMON BRAND NAME(S): Onxol, Taxol
WARNING: Paclitaxel may rarely cause serious (rarely fatal) allergic reactions. Patients who experience a severe allergic reaction with this drug must never use it again. Your doctor may prescribe other medications (such as antihistamines, corticosteroids) to help prevent an allergic reaction. However, severe allergic reactions may still occur in a few patients. Get medical help right away if you develop any signs of an allergic reaction such as rash, itching, swelling, severe dizziness, trouble breathing, or chest pain.This medication may often cause a serious blood disorder (decreased bone marrow function leading to a low number of white blood cells). This effect can lower your body's ability to fight an infection. Your doctor will monitor you closely and check your blood often during treatment. If your white blood cell count is too low, you should not receive this medication. Tell your doctor right away if you develop any signs of infection (such as sore throat that doesn't go away, fever, chills, cough, painful/difficult urination).
USES: Paclitaxel is used to treat various types of cancer. It is a cancer chemotherapy drug that works by slowing or stopping cancer cell growth.
HOW TO USE: Read the Patient Information Leaflet if available from your pharmacist before you start using paclitaxel and each time you receive a dose. If you have any questions, ask your doctor or pharmacist.This medication is given by injection into a vein by a health care professional. It is given on a schedule as directed by your doctor. Dosage is based on your medical condition, body size, and response to treatment.
SIDE EFFECTS: See also Warning section.Nausea, vomiting, diarrhea, mouth sores, muscle/joint pain, numbness/tingling/burning of the hands/feet, flushing, dizziness, or drowsiness may occur. If any of these effects last or get worse, tell your doctor promptly.Temporary hair loss may occur. Normal hair growth should return after treatment has ended.This medication may rarely cause changes to your blood pressure and heart rate. You should be closely monitored for these changes during the infusion of this medication. Tell your doctor promptly if you have increasing dizziness, headache, or a fast/slow/irregular heartbeat.People using this medication may have serious side effects. However, you have been prescribed this drug because your doctor has judged that the benefit to you is greater than the risk of side effects. Careful monitoring by your doctor may decrease your risk.Tell your doctor right away if you have any serious side effects, including: nausea/vomiting that doesn't stop, signs of anemia (such as unusual tiredness, pale skin), easy bruising/bleeding, fainting, confusion, pain/redness/swelling/weakness of the arms/legs, calf pain/swelling that is warm to the touch, coughing up blood, stomach/abdominal pain, yellowing eyes/skin, dark urine, vision/hearing changes, seizures.This medication may rarely irritate the vein it is given into or leak out of the vein and irritate the area.
