- Changes in lung tissue may happen with large amounts of this drug. These changes may not last forever, and your lung tissue may go back to normal. Sometimes these changes may not be seen for many years. You may get a cough or have trouble catching your breath.
- Changes in liver enzymes. Liver enzymes will be checked as needed.
- Skin and tissue irritation. You may have redness, pain, warmth, or swelling at the IV site. This happens if the drug leaks out of the vein and into the nearby tissue.

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 bother your mouth and throat.
- Drink 6-8 cups of fluids each day unless your doctor has told you to limit your fluid intake due to some other health problem. A cup is 8 ounces of fluid. If you throw up or have loose bowel movements, you should drink more fluids so that you do not become dehydrated (lack water in the body from losing too much fluid).
- Ask your doctor or nurse about medicine to help stop or lessen nausea and throwing up.
- While you are getting this drug in your vein, tell your nurse right away if you have any pain, redness, or swelling at the site of the IV infusion.
- If you get a rash, do not put anything on it unless your doctor or nurse says you may. Keep the area around the rash clean and dry.
- Use effective methods of birth control during your cancer treatment. Talk to your nurse or doctor about the types of birth control that should be used.
- Vaginal lubricants can be used to lessen vaginal dryness, itching, and pain during sexual relations.
- If you have kidney problems your kidney function will be checked as needed.
- If you are taking this medicine by mouth, take it on an empty stomach, at least one hour before eating or two hours after eating. Take with water and swallow the tablets whole.
- This drug may cause an increased risk of developing a second cancer
