Test tube research on human lung tissue suggests that vitamin E might reduce lung toxicity caused by amiodarone.1 More research is needed to further investigate this possibility.
Potential Negative Interaction
In one controlled study, drinking grapefruit juice while taking amiodarone dramatically increased blood levels of the drug.2 Consequently, people taking amiodarone should avoid drinking grapefruit juice (and eating grapefruit) to prevent potentially serious side effects.
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 amiodarone in the same way that grapefruit juice does.
The interaction is supported by preliminary, weak, fragmentary, and/or contradictory scientific evidence.
The Drug-Nutrient Interactions table may not include every possible interaction. Taking medicines with meals, on an empty stomach, or with alcohol may influence their effects. For details, refer to the manufacturers’ package information as these are not covered in this table. If you take medications, always discuss the potential risks and benefits of adding a new supplement with your doctor or pharmacist.
