Nifedical XL and Alcohol/Food Interactions

There are 4 alcohol/food/lifestyle interactions with Nifedical XL (nifedipine).

Moderate

NIFEdipine Alcohol (Ethanol)

Moderate Drug Interaction

MONITOR: Many psychotherapeutic and CNS-active agents (e.g., anxiolytics, sedatives, hypnotics, antidepressants, antipsychotics, opioids, alcohol, muscle relaxants) exhibit hypotensive effects, especially during initiation of therapy and dose escalation. Coadministration with antihypertensives and other hypotensive agents, in particular vasodilators and alpha-blockers, may result in additive effects on blood pressure and orthostasis.

MANAGEMENT: Caution and close monitoring for development of hypotension is advised during coadministration of these agents. Some authorities recommend avoiding alcohol in patients receiving vasodilating antihypertensive drugs. Patients should be advised to avoid rising abruptly from a sitting or recumbent position and to notify their physician if they experience dizziness, lightheadedness, syncope, orthostasis, or tachycardia.

NIFEdipine multivitamins with minerals

Moderate Drug Interaction

MONITOR: Calcium-containing products may decrease the effectiveness of calcium channel blockers by saturating calcium channels with calcium. Calcium chloride has been used to manage acute severe verapamil toxicity.

MANAGEMENT: Management consists of monitoring the effectiveness of calcium channel blocker therapy during coadministration with calcium products.

NIFEdipine food

Moderate Food Interaction

GENERALLY AVOID: The consumption of grapefruit juice may be associated with significantly increased plasma concentrations of some calcium channel blockers (CCBs) when they are administered orally. The proposed mechanism is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall by certain compounds present in grapefruit. The interaction has been reported with the dihydropyridine CCBs (in roughly decreasing order of magnitude) felodipine, nisoldipine, nifedipine, and nimodipine, often with a high degree of interindividual variability. Grapefruit juice caused more than twofold increases in felodipine, nifedipine, and nisoldipine AUCs.

MANAGEMENT: The manufacturers of nifedipine and nisoldipine recommend avoiding grapefruit juice. Patients treated orally with other calcium channel blockers should be advised to avoid consumption of large amounts of grapefruits and grapefruit juice to prevent any undue fluctuations in serum drug levels. Increased effects on blood pressure may persist for up to 4 days after the consumption of grapefruit juice. Monitoring for calcium channel blocker adverse effects (e.g., headache, hypotension, syncope, tachycardia, edema) is recommended.

High Blood Pressure (Hypertension)

Major Potential Hazard, High plausibility

nifedipine - hypertension

For the long-term treatment of hypertension, only the extended-release formulations of nifedipine should be used. The US National Heart, Lung, and Blood Institute and the FDA Cardiovascular and Renal Drug Advisory Committee have issued warnings against the use of immediate-release nifedipine for this purpose based on review of three epidemiologic studies of patients with hypertension and unstable angina who were treated with calcium channel blockers (CCBs) and at least two meta-analyses of randomized, controlled trials that included patients receiving CCBs. Two of the case-control studies found an increased risk of myocardial infarction (MI) in patients taking immediate-release nifedipine, although the third did not. The use of immediate-release nifedipine (orally or sublingually) is also contraindicated for acute reduction of blood pressure. Profound hypotension, acute myocardial infarction, and deaths have been reported when nifedipine was used in this manner.
