Risks of Overdosing Dogs on Phenobarbital: What You Need to Know

Phenobarbital is a commonly prescribed medication for managing seizures in dogs, but like any drug, it carries risks—especially when overdosed. Understanding these risks is crucial for pet owners to ensure their furry friends stay safe and healthy.

What is Phenobarbital?

Phenobarbital is a barbiturate that acts as a central nervous system depressant. It is primarily used to control epilepsy and seizures in dogs by reducing abnormal electrical activity in the brain.

Why Overdose Happens

• Incorrect Dosage: Miscalculations or changes in medication without veterinary guidance.
• Multiple Medications: Interactions with other drugs can increase phenobarbital levels.
• Accidental Ingestion: Dogs may consume more than prescribed if unsupervised.
