Amiodarone increases the sensitivity of your skin to sunlight. Too much sun exposure could cause a serious sunburn. Your skin may continue to be sensitive to sunlight for several months after treatment is stopped. Use a sunscreen when you are outdoors. Wear protective clothing and hats. Avoid sunlamps and tanning beds.

After you have taken this medicine for a long time, it may cause a blue-gray color to appear on your skin, especially in areas exposed to the sun, such as your face, neck, and arms. This color will usually fade after treatment with amiodarone has ended, although it may take several months. Check with your doctor if this color change occurs.

Grapefruit and grapefruit juice may increase the side effects of amiodarone by increasing the amount of this medicine in your body. You should not eat grapefruit or drink grapefruit juice while you are using this medicine.

Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal (eg, St. John's wort) or vitamin supplements.
