Interactions between your drugs

Major

amiodarone procainamide

Applies to: Cordarone (amiodarone) and procainamide

Talk to your doctor before using amiodarone together with procainamide. Combining these medications may occasionally worsen your heart condition or cause serious heart rhythm disturbances. In addition, amiodarone may increase the blood levels and effects of procainamide, even after you have stopped taking amiodarone for a while. Your doctor may be able to prescribe alternatives that do not interact, or you may need a dose adjustment or more frequent monitoring to safely use both medications. You should seek immediate medical attention if you develop sudden dizziness, lightheadedness, fainting, shortness of breath, or fast or pounding heartbeats during treatment with these medications, whether together or alone. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Drug and food interactions

Major

amiodarone food

Applies to: Cordarone (amiodarone)

Amiodarone may be taken with or without food but should be taken at the same way each time. You should avoid consuming grapefruits and grapefruit juice while taking amiodarone. Do not increase or decrease the amount of grapefruit products in your diet without first talking to your doctor. Grapefruit can raise the levels of amiodarone in your body and lead to dangerous side effects. This can affect the rhythm of your heart. Call your doctor if you have symptoms of irregular heartbeat, chest tightness, blurred vision or nausea.

Minor

procainamide food

Applies to: procainamide

Information for this minor interaction is available on the professional version.

It can also be unintentional in cases where a patient has been treated by more than one doctor, or had prescriptions filled at more than one pharmacy, and can have potentially adverse consequences.
