Is Hydrocodone Safe for Dogs?
Why it’s a problem
Hydrocodone is an opioid that can leave dogs deeply sedated after eating human tablets, with larger ingestions slowing breathing and heart rate enough to need hospital support. It also appears in combination cough products, where other ingredients can add toxicity.
How to keep your pet safe
Store hydrocodone tablets and any prescription cough syrups containing it out of reach. Cough control for your dog should start with your veterinarian, not with your leftover prescription.
Warning signs to watch for
Heavy sedation, stumbling, pinpoint pupils, drooling, vomiting, slowed breathing, low body temperature; severe cases: unresponsiveness, blue gums, collapse.
When to call the vet
Call your veterinarian or a pet poison hotline promptly with the product name and strength. If it is a combination product, tell the hotline all active ingredients.
Common questions
My dog got into my hydrocodone — how dangerous is it?
Dangerous — opioids can deeply sedate dogs and slow their breathing. Call your vet or a pet poison hotline now with the strength and your dog’s weight.
Is hydrocodone used in veterinary medicine?
It appears in some veterinary cough formulations under strict dosing, but human tablets are far stronger. Never give your own prescription to a pet.
