Omeprazole is a proton pump inhibitor (PPI) used to reduce stomach acid in humans and may be prescribed by veterinarians for dogs and cats with certain gastrointestinal conditions. Although it is available over-the-counter and is sometimes used in veterinary medicine, it should never be given to your pet without professional guidance. The dose, formulation, and duration appropriate for humans are not the same as those for pets, and incorrect use can lead to adverse effects or dangerous drug interactions.
Pets most commonly become exposed by chewing into a bottle of Prilosec or other omeprazole products, or by being given a human dose by a well-meaning owner. Symptoms of an adverse reaction or overdose may include vomiting, diarrhea, loss of appetite, lethargy, gas, abdominal pain, or changes in urination. Long-term or high-dose use can suppress normal stomach acid production and may increase the risk of infections, nutrient deficiencies, or interactions with other medications.
If your pet has ingested omeprazole, contact your veterinarian or a pet poison control center right away for advice. Do not attempt to induce vomiting or give additional doses unless specifically directed by a professional. Store all human medications in a secure cabinet, keep blister packs and bottles out of reach, and only use omeprazole for your pet if it has been prescribed and dosed by your veterinarian.
