Paclitaxel injection is used to treat advanced cancer of the ovaries, breast, non-small cell lung cancer, and Kaposi sarcoma. Kaposi sarcoma is a cancer of the skin and mucous membranes that is commonly found in patients with acquired immunodeficiency syndrome (AIDS).
Paclitaxel belongs to the group of medicines called antineoplastics. It interferes with the growth of cancer cells, which are eventually destroyed. Since the growth of normal body cells may also be affected, other unwanted effects will also occur. Some of these may be serious and must be reported to your doctor. Other effects may not be serious but may cause concern. Some effects may not occur until months or years after the medicine is used.
Before you begin treatment with paclitaxel, you and your doctor should talk about the good this medicine will do as well as the risks of using it.
This medicine is to be administered only by or under the immediate supervision of your doctor.

It is very important that your doctor check your progress at regular visits to make sure that this medicine is working properly. Blood tests may be needed to check for unwanted effects.
Using this medicine while you are pregnant can harm your unborn baby. Use an effective form of birth control to keep from getting pregnant. If you think you have become pregnant while using the medicine, tell your doctor right away.
This medicine may cause serious allergic reactions, including anaphylaxis. Anaphylaxis can be life-threatening and requires immediate medical attention. Tell your doctor or nurse right away if you have a cough; dizziness; wheezing; trouble with breathing; chest or throat tightness; swelling in your face or hands; fever; chills; rash; itching or hives; skin redness; or lightheadedness or faintness while you are receiving this medicine.
While you are being treated with paclitaxel, and after you stop treatment with it, do not have any immunizations (vaccines) without your doctor's approval. Paclitaxel may lower your body's resistance and the vaccine may not work as well or you might get the infection the vaccine is meant to prevent. In addition, you should not be around other persons living in your household who receive live virus vaccines because there is a chance they could pass the virus on to you. Some examples of live vaccines include measles, mumps, influenza (nasal flu vaccine), poliovirus (oral form), rotavirus, and rubella. Do not get close to them and do not stay in the same room with them for very long. If you have questions about this, talk to your doctor.
Paclitaxel can temporarily lower the number of white blood cells in your blood, increasing the chance of getting an infection. It can also lower the number of platelets, which are necessary for proper blood clotting. If this occurs, there are certain precautions you can take, especially when your blood count is low, to reduce the risk of infection or bleeding:
- If you can, avoid people with infections. Check with your doctor immediately if you think you are getting an infection or if you get a fever or chills, cough or hoarseness, lower back or side pain, or painful or difficult urination.
- Check with your doctor immediately if you notice any unusual bleeding or bruising; black, tarry stools; blood in the urine or stools; or pinpoint red spots on your skin.
- Be careful when using a regular toothbrush, dental floss, or toothpick. Your medical doctor, dentist, or nurse may recommend other ways to clean your teeth and gums. Check with your medical doctor before having any dental work done.
- Do not touch your eyes or the inside of your nose unless you have just washed your hands and have not touched anything else in the meantime.
- Be careful not to cut yourself when you are using sharp objects such as a safety razor or fingernail or toenail cutters.
- Avoid contact sports or other situations where bruising or injury could occur.
This medicine may cause peripheral neuropathy. Check with your doctor right away if you are having burning, numbness, tingling, or painful sensations in the arms, hands, legs, or feet while using this medicine.
