Cisapride is usually a safe drug. However some common risk factors have been identified which may put babies at risk for prolongation of the Q-T interval and life threatening torsades de pointes. These include:

    Premature infants (born at less than 36 weeks gestational age) from 0 through 3 months after the delivery date.

    The following medications are contraindicated with the concurrent use of cisapride. They inhibit cytochrome P450-3A4 enzyme, which metabolizes cisapride, leading to increased cisapride levels:
    • Antifungals: fluconazole, itraconazole, or ketoconazole.
    • Antibiotics: clarithromycin, erythromycin.

    There are additional medications that may interact with cisapride. for a more extensive list contact your pharmacist.

    • Pre-existing prolonged ECG QT interval
    • Renal or hepatic insufficiency
    • Ventricular arrythmias, and CHF
    • Electrolyte disturbances such as hypokalemia, hypomagnesemia
    • Respiratory Failure

Please carefully assess the need for cisapride. If cisapride is required, inform the infant's family of the risk/benefit and sign this form indicating that your are aware of the risk factors. Please ensure this form is faxed to pharmacy with your order. Place signed form in chart.

Note: Infants should have a baseline ECG performed before commencing cisapide therapy. This should be repeated at 1 week and thereafter as per clinical judgement.
