About this calculator
The omeprazole dosage calculator for dogs helps determine the correct medication amount based on the animal's weight. Omeprazole is a proton pump inhibitor used to treat gastric ulcers, gastritis, or reflux in dogs. The standard dose is 1 mg per kilogram of body weight (1 mg/kg), administered once or twice daily.
To calculate the dose, enter the dog's weight and multiply by 1 mg/kg. The result indicates the total daily dosage, which can be split into smaller doses according to veterinary instructions. The drug is typically given with food to reduce gastric irritation and improve absorption.
Use this calculator only as an initial guideline. The exact dose depends on factors like condition severity, treatment response, and possible drug interactions. Never administer omeprazole without professional guidance, especially in dogs with liver or kidney issues.
Self-medication may cause side effects like diarrhea, nausea, or drowsiness. Veterinary follow-up is essential to adjust the dose and monitor complications. Long-term use may lead to vitamin deficiencies, such as B12.
