Ondansetron acts on the serotonergic pathway to control nausea and vomiting.

- Chemotherapy-induced nausea and vomiting: prevention of acute and delayed nausea and vomiting in patients receiving emetogenic chemotherapy. - Radiation-induced nausea and vomiting: reduction of nausea and vomiting associated with radiotherapy to the abdomen or pelvis. - Postoperative nausea and vomiting: prophylaxis of nausea and vomiting following surgical procedures.

Ondansetron may cause a range of adverse reactions, varying from mild to severe.

Common Side Effects: - Headache - Constipation - Dizziness - Fatigue - Diarrhea

Serious or Rare Side Effects: - QT interval prolongation and cardiac arrhythmias - Severe allergic reactions such as anaphylaxis - Serotonin syndrome, especially when combined with other serotonergic drugs - Hypotension and syncope

When using Ondansetron, several safety considerations should be observed.

- Cardiac risk assessment: evaluate baseline QT interval and correct electrolyte abnormalities before initiating therapy. - Hypersensitivity: avoid use in patients with known allergy to ondansetron or other 5‑HT3 antagonists. - Hepatic impairment: use with caution and consider dose adjustment in moderate to severe liver disease. - Electrolyte balance: monitor and correct hypokalemia or hypomagnesemia which can predispose to cardiac events. - Pregnancy and lactation: weigh potential benefits against risks; use only if clearly needed. - Store at below 25°C: keep in the original packaging, protect from moisture and light.

Ondansetron can interact with other medicines, affecting its safety or effectiveness.

Major Interactions (Avoid): - Concomitant use with other QT‑prolonging agents (e.g., quinidine, haloperidol) may increase risk of serious arrhythmias. - Co‑administration with apomorphine can cause severe hypotension and loss of consciousness. - Combining with other 5‑HT3 antagonists offers no additional benefit and may increase toxicity.

Moderate Interactions (Monitor Closely): - Strong CYP3A4 inhibitors (e.g., erythromycin, ketoconazole) can raise ondansetron plasma concentrations. - CYP2D6 substrates (e.g., codeine, tramadol) may have altered metabolism when given with ondansetron. - Rifampin and other CYP inducers may reduce ondansetron effectiveness.
