ALERT ON ESMOLOL (BREVIBLOC) INJECTION:

FDA has received reports of several deaths when the wrong concentration (2500 mg/10-mL) of BREVIBLOC (Esmolol Hydrochloride Injection) was administered. Two concentrations are available.

The CONCENTRATE, available in a 10-mL ampule containing 2500 mg (2.5 grams) of Esmolol, is intended for DILUTION ONLY. The product is also available in a 10-mL vial (100 mg) intended for direct bolus injection.

The manufacturer has changed the labeling of the ampule to include a red warning sticker on the neck. As an additional safety measure, we recommend that access to the ampule be restricted to personnel who normally prepare the solutions.
