Description

Bleomycin (blee-oh-MYE-sin) belongs to the general group of medicines called antineoplastics. It is used to treat several types of cancer, including cervix and uterus cancer, head and neck cancer, testicle and penile cancer, and certain types of lymphoma. Bleomycin also may used for other conditions, as determined by your doctor.

Bleomycin seems to act by interfering with the growth of cancer cells, which are eventually destroyed. Since the growth of normal body cells may also be affected by bleomycin, other effects will also occur. Some of these may be serious and must be reported to your doctor. Other effects, like darkening of skin or hair loss, may not be serious but may cause concern. Some effects may not occur for months or years after the medicine is used.

Before you begin treatment with bleomycin, you and your doctor should talk about the good this medicine will do as well as the risks of using it.

Bleomycin is to be administered only by or under the immediate supervision of your doctor. It is available in the following dosage form:

• Parenteral
• Injection (U.S. and Canada)

Before Using This Medicine

In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For bleomycin, the following should be considered:

Allergies—Tell your doctor if you have ever had any unusual or allergic reaction to bleomycin.

Pregnancy—Studies have not been done in pregnant women. However, there is a chance that this medicine may cause birth defects if either the male or female is receiving it at the time of conception or if it is used during pregnancy. Studies in mice given large doses of bleomycin have shown that it causes birth defects. In addition, many cancer medicines may cause sterility which could be permanent. Although sterility has not been reported with this medicine, the possibility should be kept in mind.

Be sure that you have discussed this with your doctor before receiving this medicine. It is best to use some kind of birth control while you are receiving bleomycin. Tell your doctor right away if you think you have become pregnant while receiving bleomycin.

Breast-feeding—Because bleomycin may cause serious side effects, breast-feeding is generally not recommended while you are receiving it.

Children—Although there is no specific information comparing use of bleomycin in children with use in other age groups, this medicine is not expected to cause different side effects or problems in children than it does in adults.

Older adults—Lung problems are more likely to occur in elderly patients (over 70 years of age), who are usually more sensitive to the effects of bleomycin.

Other medical problems—The presence of other medical problems may affect the use of bleomycin. Make sure you tell your doctor if you have any other medical problems, especially:

• Kidney disease—Effects of bleomycin may be increased because of slower removal from the body

• Liver disease—Bleomycin can cause liver problems

• Lung disease—Bleomycin may worsen the condition

Bleomycin is sometimes given together with certain other medicines. If you are using a combination of medicines, it is important that you receive each medicine at the proper time. If you are taking some of these medicines by mouth, ask your health care professional to help you plan a way to take them at the right times.

Bleomycin often causes nausea, vomiting, and loss of appetite. However, it is very important that you continue to receive the medicine, even if you begin to feel ill. Ask your health care professional for ways to lessen these effects.

Dosing—The dose of bleomycin will be different for different patients. The dose that is used may depend on a number of things, including what the medicine is being used for, the patient"s weight, and whether or not other medicines are also being taken. If you are receiving bleomycin at home, follow your doctor"s orders or the directions on the label . If you have any questions about the proper dose of bleomycin, ask your doctor.
