Should veterinarians split human-manufactured medications to adjust dosages for smaller dogs?

Veterinary researchers in North Carolina have determined that splitting 500-mg extended-release levetiracetam tablets maintains consistent drug release in dogs. Conversely, crushing the medication causes it to drop below necessary therapeutic levels prematurely.

Why it matters

The study addresses a common challenge for veterinarians who must adjust dosages for small dogs that do not require full 500-mg tablets. Finding safe administration methods ensures consistent seizure control for canine patients.

Researchers studied 7 beagles using 500-mg extended-release tablets. Intact and split pills maintained target levels for nearly 11 hours, while crushed versions failed after 8.5 hours.

The players

North Carolina State University

This institution is a public research university that conducted the study on canine medication administration.

American Journal of Veterinary Research

This is a peer-reviewed scientific journal that publishes research related to veterinary medicine and animal health.

The details

Researchers at North Carolina State University cut split tablets into equal halves using a standard pill cutter for the study. Crushed tablets, which failed to maintain consistent release, were ground with a mortar and pestle before being mixed with water and delivered by syringe.

The initial study on canine epilepsy medication compliance occurred in 2021.
A dissolution study regarding levetiracetam was published in 2025.
The new research findings were published on October 23, 2026.

Culture Shift

This research follows a pattern set by the American Journal of Veterinary Research to provide evidence-based guidelines for everyday pet care. It highlights a growing need for precise medication administration protocols in veterinary medicine.

Pet owners in North Carolina should consult their veterinarian before altering any prescribed medication for their dog. This study provides a practical, safer alternative for dose adjustment compared to grinding pills.

The takeaway

Always consult your veterinarian before attempting to split or crush extended-release tablets for your pet. Using the correct administration method is vital to ensuring your dog maintains the necessary medication levels to prevent seizures.
