About this medicine

Meloxicam relieves pain and inflammation.

NSAIDs can affect the stomach, liver and kidneys. Vets usually recommend blood tests before and during long-term use.

Questions owners ask

Can Meloxicam cause didn't stop worms in dogs?

How soon after a dose was it reported?
In half of the reports with dates, it started within 166 days of the first dose.
What should I do?
Don't give another dose until you've spoken to your vet, and keep the packaging so you can tell them the product and dose. Your vet can also report it to the FDA (or you can, through the manufacturer or FDA form 1932a).
