Bretylium: uses, dosing, side effects & brands

It depends on the medicine. We check it against the FDA labels rather than guessing: our interaction checker searches each drug's own label for the other and quotes what it says, naming the section it came from. Run bretylium against whatever else you take — and remember that a label not naming a drug is not the same as that combination being safe.

We track 2 bretylium-containing products in the U.S.: Bretylium Tosylate and Bretylol. They are the same active ingredient; they differ in form, manufacturer, price and FDA recall record.

Across the brands we track, bretylium is currently marketed as injectable, per the FDA's National Drug Code Directory. Each form is dosed differently — follow the label for the exact product you were prescribed.

Yes. Our catalog lists 1 generic bretylium product alongside the brand versions. A generic has the same active ingredient and must meet the FDA's bioequivalence standard; it usually costs less. Ask your pharmacist which one your plan covers.
