Important: How To Use This Information

This is a summary and does NOT have all possible information about this product. This information does not assure that this product is safe, effective, or appropriate for you. This information is not individual medical advice and does not substitute for the advice of your health care professional. Always ask your health care professional for complete information about this product and your specific health needs.

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. The 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.

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.

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.

This medication may rarely irritate the vein it is given into or leak out of the vein and irritate the area. These effects may cause redness, pain, swelling, discoloration, or unusual skin reactions at the injection site, either while the drug is given or rarely 7 to 10 days later. If this drug has leaked out of a vein and caused a skin reaction in the past, you may rarely have a skin reaction in that same area when the drug is given again, even when it is given into another area.
