Ondansetron is a 5‑HT3 receptor antagonist used to manage nausea and vomiting.

Chemotherapy-induced nausea and vomiting: prevents and controls nausea and vomiting in patients receiving cytotoxic chemotherapy. Postoperative nausea and vomiting: reduces the incidence of nausea and vomiting after surgical procedures. Radiotherapy-induced nausea and vomiting: helps control nausea and vomiting associated with radiation therapy.

Common Side Effects: - Headache: mild to moderate headache may occur. - Constipation: reduced bowel movements are reported. - Dizziness: occasional light‑headedness. - Fatigue: feeling of tiredness. - Diarrhea: loose stools in some patients.

Serious or Rare Side Effects: - QT interval prolongation: may lead to cardiac arrhythmias. - Severe allergic reaction: rash, itching, swelling, or anaphylaxis. - Serotonin syndrome: rare but potentially life‑threatening when combined with serotonergic agents. - Cardiac arrhythmia: irregular heartbeats requiring medical attention.

Precautions should be observed when using Ondansetron.

Assess cardiac history: evaluate risk of QT prolongation before initiating therapy. Monitor electrolytes: correct hypokalemia or hypomagnesemia to reduce cardiac risk. Use with caution in hepatic impairment: consider dose adjustment or close monitoring. Avoid concomitant use with other QT‑prolonging drugs: assess cumulative risk. Store at room temperature: keep in the original packaging, protect from moisture and light.

Ondansetron may interact with several medications.

Major Interactions (Avoid): - Other 5‑HT3 antagonists: additive effect on QT interval. - Class I antiarrhythmics (e.g., quinidine): increased risk of arrhythmia. - Strong CYP3A4 inhibitors (e.g., ketoconazole): may raise plasma concentrations.

Moderate Interactions (Monitor Closely): - CYP2D6 substrates (e.g., tramadol): altered metabolism may occur. - Apomorphine: can cause severe hypotension when combined. - Anticholinergic agents: may enhance anticholinergic side effects.
