Ondansetron is a selective 5‑HT3 receptor antagonist used to manage nausea and vomiting across several clinical pathways. - Chemotherapy‑induced nausea and vomiting: Reduces the frequency and severity of acute and delayed episodes. - Radiation‑induced nausea and vomiting: Helps control nausea during and after radiotherapy. - Post‑operative nausea and vomiting: Decreases the incidence of nausea and vomiting following surgical procedures.

Adverse reactions to ondansetron are generally mild but can vary in severity.

Common Side Effects: - Headache: mild to moderate intensity. - Constipation: reduced bowel movements. - Diarrhoea: loose stools. - Fatigue: feeling of tiredness. - Dizziness: light‑headed sensation.

Serious or Rare Side Effects: - QT interval prolongation: cardiac rhythm changes that may lead to arrhythmia. - Severe allergic reaction: rash, itching, swelling, or difficulty breathing. - Serotonin syndrome: agitation, hyperreflexia, rapid heart rate when combined with other serotonergic agents.

When using ondansetron, consider the following safety measures: - Cardiac monitoring: patients with known prolonged QT interval should be evaluated before use. - Electrolyte balance: correct hypokalaemia or hypomagnesaemia to reduce cardiac risk. - Concomitant serotonergic drugs: avoid or monitor for serotonin syndrome. - Pregnancy: use only if the potential benefit justifies the risk. - Breastfeeding: assess risk versus benefit before continuation. - Store below 25°C: keep in the original packaging, protect from moisture and direct sunlight.

Ondansetron may interact with several drug classes, requiring attention to dosage and monitoring.

Major Interactions (Avoid): - Apomorphine: may cause profound hypotension and loss of consciousness. - Certain anti‑arrhythmic agents (e.g., amiodarone, quinidine): increase risk of QT prolongation.

Moderate Interactions (Monitor Closely): - Other serotonergic agents (e.g., SSRIs, tramadol): risk of serotonin syndrome. - CYP3A4 inhibitors (e.g., ketoconazole, erythromycin): may raise ondansetron plasma levels. - CYP2D6 inhibitors (e.g., fluoxetine, paroxetine): may increase exposure. - Diuretics that cause electrolyte loss: monitor potassium and magnesium levels.
