This medication is used to treat cancer (such as breast, lung, prostate, stomach, and head/neck cancer). Docetaxel is a member of a family of drugs called taxanes. This drug works by slowing cell growth.

Read the Patient Information Leaflet if available from your pharmacist before you start receiving docetaxel and each time you get a treatment. If you have any questions, ask your doctor, nurse, or pharmacist.

This medication is given by injection into a vein by a health care professional. It is given as directed by your doctor, usually over 1 hour every 3 weeks. The dosage and frequency is based on your medical condition, body size, and response to treatment.

Your doctor may prescribe pre-medications (such as corticosteroids such as dexamethasone) to prevent side effects like swelling (fluid retention/edema) and allergic reactions. These are generally started 1 day before treatment and continued for a total of 3 days. Carefully follow your doctor's orders to prepare for your treatment. If you forget to take your pre-medication, or do not take it on schedule, tell your doctor or nurse before you receive your docetaxel treatment.

See also Warning section.

Pain or swelling at the injection site, nausea, vomiting, diarrhea, excessive tearing, tiredness, dizziness, drowsiness, feeling drunk, constipation, and loss of appetite may occur. Nausea and vomiting can be severe. In some cases, your doctor may prescribe medication to prevent or relieve nausea and vomiting. Eating several small meals, not eating before treatment, or limiting activity may help lessen some of these effects. If any of these effects last or get worse, tell your doctor or pharmacist promptly.

Temporary hair loss and nail changes may occur. Normal hair growth and nail appearance should return after treatment has ended. However, hair loss may be permanent for some people.

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:

• unusual tiredness/weakness
• swelling ankles/feet/hands
• unexplained weight gain
• swelling abdomen
• easy bruising/bleeding
• mouth sores
• numbness/tingling of arms/legs
• muscle/joint pain
• eye pain
• irregular heartbeat
• stomach/abdominal pain
• severe diarrhea
• diarrhea with blood or mucus
• severe headache

This medication can decrease your body's ability to fight an infection. Tell your doctor right away if you develop any signs of an infection (such as a sore throat that doesn't go away, fever, or chills).

Although docetaxel is used to treat cancer, it may rarely increase your risk of getting other cancers (such as acute myeloid leukemia-AML, Non-Hodgkin's Lymphoma, kidney cancer). This may occur months to years after treatment. Your doctor should monitor you closely while you receive this medication and after treatment with this medication.

Docetaxel sometimes causes side effects due to the rapid destruction of cancer cells (tumor lysis syndrome). To lower your risk, your doctor may add a medication and tell you to drink plenty of fluids. Tell your doctor right away if you have symptoms such as:

• low back/side pain (flank pain)
• signs of kidney problems (such as painful urination, pink/bloody urine, change in the amount of urine)
• muscle spasms/weakness

Get medical help right away if you have any very serious side effects, including:

• chest pain
• vision changes (such as blurred vision, decreased vision, seeing flashes of light)

A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including:

• rash
• itching/swelling (especially of the face/tongue/throat)
• severe dizziness
• trouble breathing
