Consuming large amounts of mangoes or mango juice may increase the bioavailability of certain calcium channel blockers like felodipine, potentially leading to enhanced pharmacological effects and side effects. This interaction is milder than with grapefruit but warrants caution.
Avoid large quantities (>1 cup juice or multiple fruits daily) to minimize risk.
Interaction primarily affects oral bioavailability; not seen with other forms of intake.
Consult pharmacist for personalized advice on specific heart medications.
Safer alternatives: Berries or apples with minimal CYP3A4 inhibition.
Mango juice contains compounds that inhibit the CYP3A4 enzyme in the intestinal wall, reducing the first-pass metabolism of CYP3A4 substrate drugs such as felodipine. This results in higher systemic drug concentrations.
Elevated drug levels can cause excessive blood pressure lowering, leading to hypotension, dizziness, headache, flushing, or tachycardia. In severe cases, it may increase the risk of cardiovascular events.
Limit intake of mangoes or mango juice while on these medications. Monitor blood pressure closely. If interaction is suspected, consider alternative fruits or consult a healthcare provider for dose adjustments. The effect is dose-dependent on mango consumption.

Hot chocolate contains small amounts of tyramine and phenylethylamine, which can interact with MAOIs, potentially leading to a hypertensive crisis if consumed in large quantities, though the risk is generally low with moderate intake.
Kale, a vitamin K-rich leafy green, can interact with warfarin by potentially reducing its anticoagulant effects if intake is inconsistent or excessive.
Large amounts of lime juice may mildly interact with certain statins, similar to but less potent than grapefruit juice, by inhibiting drug metabolism and potentially increasing statin levels in the blood.
