Is Famotidine safe to give at home?
Famotidine may reduce stomach acid when a veterinarian recommends it for that pet. A human tablet strength is not a pet dose, and kidney function changes the plan. Do not use it to delay care for repeated vomiting or a pet who will not eat.
Veterinary use
- Stomach-acid reduction when a veterinarian recommends it

Weight and dosage reference
Do not calculate a home dose from this page. A veterinarian uses the animal's weight in pounds (kilograms), the species, and the exact product. This database does not publish a milligram chart, and a dose must never be copied from another pet.
Famotidine is dosed from body weight and kidney function. A human tablet strength is not a pet dose. This database does not give a home milligram chart; do not use it to delay care for a pet who is vomiting repeatedly or not eating.
Overdose and toxic exposure
Large overdoses are uncommon in household reports, but an already dehydrated or kidney-compromised pet can be harmed by an unplanned course. A veterinarian sets any amount from the animal's weight in pounds (kilograms) and the exact product in hand. This page does not publish a home milligram chart.
- Lethargy
- Vomiting
- A slow heart rate in significant overdose
What the emergency vet will do
