Is Glipizide (Glucotrol) Safe for Dogs?
Why it’s a problem
Glipizide stimulates insulin release regardless of whether a dog needs it, and overdoses have been reported to cause severe low blood sugar with weakness, tremors, and seizures. Small dogs are especially vulnerable because a single human tablet is a large dose for them. Prolonged hypoglycemia can become life-threatening without treatment.
How to keep your pet safe
Keep glipizide and all diabetes medications in secure storage, and never leave a pill organizer within a dog’s reach. Any blood-sugar concern for your dog should go through your veterinarian.
Warning signs to watch for
Weakness, wobbliness, trembling, lethargy, vomiting, hunger, drooling; severe hypoglycemia: seizures, collapse, unresponsiveness.
When to call the vet
Call your veterinarian or a pet poison hotline immediately — low blood sugar can worsen for hours after ingestion. Report the tablet strength, the number possibly eaten, and your dog’s weight.
Common questions
My dog ate my Glucotrol — is one pill dangerous?
For small dogs, yes — one tablet can drive blood sugar dangerously low. Call your vet or a pet poison hotline now with the dose and your dog’s weight.
What are the signs of low blood sugar in dogs?
