Ingestion of grapefruit juice has been shown to increase the absorption of felodipine (a drug similar in structure and action to that of nifedipine) and to increase the adverse effects of the medication in patients with hypertension. People taking nifedipine or similar drugs should not consume grapefruit juice or grapefruit, unless they have discussed it with their physician.1
As pleurisy root and other plants in the Aesclepius genus contain cardiac glycosides, it is best to avoid use of pleurisy root with heart medications such as calcium channel blockers.2
Pomegranate juice has been shown to inhibit the same enzyme that is inhibited by grapefruit juice.3 , 4 The degree of inhibition is about the same for each of these juices. Therefore, it would be reasonable to expect that pomegranate juice might interact with nifedipine in the same way that grapefruit juice does.
