About Omeprazole

Omeprazole is an acid reducer, a class used for stomach upset and reflux. You will see it sold as Prilosec, and the label strength on the box is what matters for the math, not the brand. Reference data on this page reflects published veterinary sources, not a prescription for your cat.

What to have ready when you call the vet

Whether you are confirming a dose or reporting that your cat already got into something, the call goes faster with four facts ready: your cat's current weight, the exact product name and strength from the label, how much was given or eaten, and roughly when. With those, most clinics can answer in one call.

The safe habit

Confirm any medication decision with your veterinarian, who knows your cat's health history and other medications. VetDose shows published reference data, not prescriptions.
