Plain-English summary

A 5-year-old dog had more frequent seizures after receiving a flavored phenobarbital solution that had gone bad before its expiration date. Another dog showed signs of high potassium levels and bromine toxicity due to a serious mistake in the concentration of potassium bromide, which was five times stronger than it should have been. Both dogs needed immediate veterinary attention to address these issues. After correcting the medication errors, the dogs were treated and their conditions improved.

Abstract

Two cases that involve drug compounding errors are described. One dog exhibited increased seizure activity due to a compounded, flavored phenobarbital solution that deteriorated before the expiration date provided by the compounder. The other dog developed clinical signs of hyperkalemia and bromine toxicity following a 5-fold compounding error in the concentration of potassium bromide (KBr).
