Application of carvedilol in a dog with pseudoephedrine toxicosis-induced tachycardia.

A 15-year-old Yorkshire terrier dog was presented after ingesting 1 capsule of an over-the-counter cold medication containing pseudoephedrine (120 mg/capsule) and cetirizine (5 mg/capsule). Treatment was initiated with acepromazine and carvedilol. The dog responded well to treatment. This is the first known case report using carvedilol to control pseudoephedrine toxicosis.
