Does Amiodarone Hydrochloride Interact with Propranolol?
CDI records a major classification for Amiodarone Hydrochloride and Propranolol. The stored summary is: Antihypertensives: Use amiodarone with caution in patients receiving ß-receptor blocking agents (e.g., propranolol, a CYP3A inhibitor) or calcium channel antagonists (e.g., verapamil, a CYP3A substrate, and diltiazem, a CYP3A inhibitor) because of the possible potentiation of bradycardia, sinus arrest, and AV block; if necessary, amiodarone can continue to be used after insertion of a pacemaker in patients with severe bradycardia or sinus arrest. Hemodynamic and electrophysiologic interactions have also been observed after concomitant administration with propranolol, diltiazem, and verapamil. Patients taking both medications should consult their healthcare provider before starting, stopping, or changing the dosage of either drug. This record was extracted from drug labeling through openFDA. NIH/NLM RxNorm is used for drug identities. The summary and severity classification are CDI's processed information, not a verbatim source quotation. Product, route, and patient circumstances matter.

What To Tell Your Doctor or Pharmacist
If you are taking Amiodarone Hydrochloride and your doctor is considering prescribing Propranolol (or vice versa), make sure to:
- Inform your doctor and pharmacist of all current medications, including over-the-counter drugs and supplements
- Ask whether the benefits of combining these medications outweigh the risks for your specific situation
- Ask what symptoms to watch for that would indicate the interaction is causing problems
- Ask how frequently you should be monitored while these are co-prescribed
- Ask whether any dosage adjustments are needed
- Never stop or change either medication without first consulting your healthcare provider
