Possible side effects
- Allergic reactions to this drug are rare, but may occur in some patients. Signs of allergic reaction are shortness of breath, wheezing, rash or itching, dizziness or lightheadedness, or palpitations (feeling your heart beat rapidly).
- Bone marrow depression. This is a decrease in the number of white blood cells, red blood cells, and platelets. Bone marrow depression may increase your risk of infection, fatigue, and bleeding.

- Sexual problems and reproduction concerns may occur. In men and women both, this drug may temporarily or permanently affect your ability to have children. This cannot be determined before your therapy. In men, this drug may interfere with your ability to make sperm, but it should not change your ability to have sexual relations. In women, menstrual bleeding may become irregular or stop while you are receiving this drug. Do not assume that you cannot become pregnant if you do not have a menstrual period. Women may experience signs of menopause, like vaginal dryness or itching.
- This drug may have harmful effects on the unborn child, so effective methods of birth control should be used during your cancer treatment.
- Genetic counseling is available to you to discuss the effects of this drug therapy on future pregnancies. In addition, a genetic counselor can review the potential risks of problems in the fetus due to this medication if an exposure during pregnancy has occurred.
Treating side effects
- Mouth care is very important. Your mouth care should consist of gently brushing with a very soft tooth brush and rinsing your mouth with a mixture of 1/2 teaspoon of salt in 8 ounces of water or 1/2 teaspoon of sodium bicarbonate (baking soda) in 8 ounces of water. This should be done at least after every meal and at bedtime.
- Avoid mouthwash that contains alcohol. Avoid alcohol and smoking because they can irritate your mouth and throat.
- Ask your doctor or nurse about medication to help prevent or lessen nausea and vomiting.
- Use effective methods of birth control during your cancer treatment.
- Vaginal lubricants can be used to lessen vaginal dryness, itching, and pain during sexual relations.
- Speak with your doctor or nurse if you plan to have children. Ask for information on sperm or egg banking.
- Do not put anything on your rash unless your doctor or nurse says you may. Keep the area around the rash clean and dry.
