Granisetron belongs to a class of medications called 5-HT3 blockers. It works by blocking one of the body\'s natural substances (serotonin) that can cause vomiting.

Before using granisetron, tell your doctor or pharmacist if you are allergic to it; or to other 5-HT3 blockers (e.g., dolasetron, ondansetron); or if you have any other allergies.

Granisetron may cause a condition that affects the heart rhythm (QT prolongation). QT prolongation can infrequently result in serious (rarely fatal) fast/irregular heartbeat and other symptoms (such as severe dizziness, fainting) that require immediate medical attention. The risk of QT prolongation may be increased if you have certain medical conditions or are taking other drugs that may affect the heart rhythm (see also Drug Interactions section). Before using granisetron, tell your doctor or pharmacist if you have any of the following conditions: certain heart problems (heart failure, slow heartbeat, QT prolongation in the EKG), family history of certain heart problems (QT prolongation in the EKG, sudden cardiac death).
Low levels of potassium or magnesium in the blood may also increase your risk of QT prolongation. This risk may increase if you use certain drugs (such as diuretics/\"water pills\") or if you have conditions such as severe sweating, diarrhea, or vomiting. Talk to your doctor about using granisetron safely.
During pregnancy, this medication should be used only when clearly needed. Discuss the risks and benefits with your doctor.
