The administration of ezetimibe (Zetia) requires attention to the timing of dosing, handling of missed doses, and the principles of discontinuation. While the medication is not affected by food intake, adjustments may be necessary under specific circumstances. Missed doses should be addressed based on the time elapsed, and discontinuation should be managed by gradually reducing the dosage under medical supervision. The following sections provide detailed explanations from three aspects: dosing timing, missed dose handling, and discontinuation recommendations.

1 Medication Timing

(1) General recommendation: Take at fixed times daily, either on an empty stomach or after meals. Food does not affect bioavailability.

(2) Special Adjustment: If gastrointestinal discomfort occurs, it is recommended to take the medication with meals to alleviate symptoms.

(3) Combined medication: When used with statins, administration in the evening is recommended to synergistically inhibit cholesterol synthesis.

2 Missed Dose Handling

(1) General Principle: Take the missed dose immediately upon discovery; skip it if it is close to the next scheduled medication time.

(2) Time Judgment: If the missed dose exceeds 12 hours beyond the regular medication time, it should not be taken, and the original schedule should be continued the next day.

(3) Contraindications: Do not take double doses to compensate; avoid increasing the risk of adverse reactions.

3 Discontinuation Recommendations

(1) Medical Guidance: Gradual dose reduction under medical supervision is required, as abrupt discontinuation may lead to lipid rebound.

(2) Dose reduction plan: Typically, half the dose is maintained for 2-4 weeks before discontinuation, with intensified lipid monitoring during this period.

(3) Special circumstances: Discontinue medication immediately if severe liver damage (ALT > 3 times the upper limit) or a significant increase in creatine kinase occurs.
