Drug Interactions:
  • Nifedipine is metabolized by CYP3A4. Co-administration of nifedipine with phenytoin, an inducer of CYP3A4, lowers the systemic exposure to nifedipine by approximately 70%. Avoid co-administration of nifedipine with phenytoin or any known CYP3A4 inducer or consider an alternative antihypertensive therapy.
  • Nifedipine is transferred through breast milk. PROCARDIA XL should be used during breastfeeding only if the potential benefit justifies the potential risk.
