Cautions

• Before taking ondansetron, tell your doctor or pharmacist if you are allergic to it; or to other serotonin blockers (such as granisetron); or if you have any other allergies. This product may contain inactive ingredients, which can cause allergic reactions or other problems. Talk to your pharmacist for more details.
• Before using this medication, tell your doctor or pharmacist your medical history, especially of: irregular heartbeat, liver disease, and stomach/intestinal problems (such as recent abdominal surgery, ileus, and swelling).
• Ondansetron may cause a condition that affects the heart rhythm (QT prolongation). QT prolongation can rarely cause serious (rarely fatal) fast/irregular heartbeat and other symptoms (such as severe dizziness, and fainting) that need medical attention right away.
• The risk of QT prolongation may be increased if you have certain medical conditions or are taking other drugs that may cause QT prolongation. Before using ondansetron, tell your doctor or pharmacist of all the drugs you take and 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 ondansetron safely.
• This drug may make you dizzy or drowsy. Alcohol or marijuana (cannabis) can make you more dizzy or drowsy. Do not drive, use machinery, or do anything that needs alertness until you can do it safely. Limit alcoholic beverages. Talk to your doctor if you are using marijuana (cannabis).
• Older adults may be more sensitive to the side effects of this drug, especially QT prolongation (see above).
• During pregnancy, this medication should be used only when needed. It may harm an unborn baby. Discuss the risks and benefits with your doctor.
