Many people using this medication do not have serious side effects.Diarrhea is a common side effect of this medication. It may become very severe (possibly fatal). To decrease this side effect, your doctor may prescribe medication (e.g., loperamide) to control your symptoms, replace lost fluids by vein, or stop treatment with capecitabine. Drink plenty of fluids to prevent serious problems due to a loss of too much body water (dehydration). If you experience signs of severe diarrhea (e.g., 4 or more stools per day, diarrhea at night, bloody stools), or if you experience signs of dehydration (e.g., dizziness, decreased amount of urine), stop taking this drug and tell your doctor immediately.Stop taking capecitabine and tell your doctor immediately if you have any of these serious side effects: severe nausea/vomiting (vomiting 2 or more times per day, inability to eat or keep food/fluids in your stomach), painful redness/swelling/sores in mouth or throat.If any of the above symptoms occur, your doctor may lower your dose when you start taking capecitabine again or may stop treatment with this drug.Treatment with capecitabine may sometimes cause your hands/feet to develop a skin reaction called hand-foot syndrome (palmar-plantar erythrodysesthesia). You can prevent or reduce these problems by protecting your hands and feet from a great deal of heat or pressure. Avoid unnecessary exposure to heat (e.g., hot dishwater, long hot baths). Avoid pressure on elbows, knees, and soles of feet (e.g., leaning on elbows, kneeling, long walks). Wear loose clothing. Depending on how severe your hand-foot syndrome is, your doctor may prescribe a medication to reduce the symptoms or decrease/delay your next dose of capecitabine. If you experience pain/swelling/redness, blisters, or numbness of the hands/feet that affects your usual activities, stop taking this medication and tell your doctor immediately.This medication can lower your ability to fight an infection.
