Ondansetron is a selective 5‑HT3 receptor antagonist used to manage nausea and vomiting in several clinical settings.

- Chemotherapy‑induced nausea and vomiting: helps prevent and control episodes of nausea and vomiting caused by cytotoxic drugs. - Radiation‑induced nausea and vomiting: reduces the frequency and severity of nausea and vomiting after radiation therapy. - Post‑operative nausea and vomiting: decreases the incidence of nausea and vomiting following surgical procedures. - Hyperemesis gravidarum (severe pregnancy‑related nausea): used off‑label in some regions to control severe nausea when other treatments have failed.

Common Side Effects: - Headache: mild to moderate headache may occur. - Constipation: reduced bowel movements are reported. - Diarrhoea: occasional loose stools. - Fatigue: feeling of tiredness or reduced energy. - Dizziness: light‑headed sensations. - Injection site reactions (if applicable): mild redness or discomfort.

Serious or Rare Side Effects: - Cardiac arrhythmia: QT‑interval prolongation may lead to irregular heart rhythms. - Severe allergic reaction: signs include rash, itching, swelling, severe dizziness, or trouble breathing. - Serotonin syndrome: rare but possible when combined with other serotonergic agents. - Hepatic dysfunction: elevated liver enzymes indicating liver stress. - Persistent visual disturbances: rare changes in vision. - Severe constipation or intestinal obstruction: rare gastrointestinal complications.

When using Ondansetron, consider the following precautions:

- Cardiac monitoring: patients with known QT prolongation or electrolyte imbalance should be monitored. - Electrolyte balance: correct potassium, magnesium, and calcium levels before initiating therapy. - Drug interactions: review concomitant medications for potential serotonergic or QT‑prolonging effects. - Pregnancy and lactation: use only if clearly needed; discuss risks with a healthcare professional. - Renal or hepatic impairment: dose adjustment may be required; monitor organ function. - Store at below 25°C: keep in the original packaging, protect from moisture and direct sunlight.

Ondansetron may interact with several medications, requiring careful review.

Major Interactions (Avoid): - Anti‑arrhythmic drugs (e.g., amiodarone, quinidine): may increase risk of QT prolongation. - Certain antibiotics (e.g., erythromycin, clarithromycin): can potentiate QT prolongation. - Serotonergic agents (e.g., tramadol, linezolid, SSRIs): heightened risk of serotonin syndrome.

Moderate Interactions (Monitor Closely): - Antifungal azoles (e.g., fluconazole, ketoconazole): may modestly increase ondansetron levels. - Antihistamines (e.g., diphenhydramine): may enhance sedative effects. - Oral contraceptives: potential reduction in contraceptive efficacy.
