In some cases, your doctor may prescribe medication to prevent or relieve nausea and vomiting.

If any of these effects last or get worse, tell your doctor or pharmacist promptly. Diarrhea is a common side effect of this medication. Drink plenty of fluids unless directed otherwise. Your doctor may also prescribe medication (such as loperamide) to help lessen diarrhea. Vomiting or diarrhea that doesn't stop may result in a serious loss of body water (dehydration).

Normal hair growth should return after treatment has ended. Also, temporary nail changes may occur. People using this medication may have serious side effects.
