Eat a well- balanced diet with plenty of fiber. Good sources of fiber are fruits, vegetables, legumes, and whole-grain bread and cereal (especially bran). Drink 1 1/2 to 2 quarts of water and other fluids a day (unless your doctor has you on a fluid-restricted diet). Fiber and water work together to keep you regular.

Zofran can be taken with or without food. The first dose is usually taken before the start of your surgery, chemotherapy, or radiation treatment. Follow your doctor's dosing instructions very carefully. Take the regular tablet with a full glass of water.
