What exactly is metformin?

Metformin is a widely used human drug that’s even older than I am, as it was first used for human diabetics back in 1957. Although its most common use is to reduce blood sugar in diabetics, through the decades we have learned that metformin reduces inflammation, body weight, and the progression of heart disease. There’s even evidence that it can help fight cancer

With so many advantages, it’s a great option for boosting your pet’s longevity.

FAQs about metformin and dogs

Metformin is a drug that can be used safely in dogs at the dosages recommended by your veterinarian or by Dr. Kevin as part of a consult. Dogs with kidney problems should not be given metformin.

Metformin is a prescription drug; thus, you’ll need either a prescription from your local veterinarian or a concierge consult with Dr. Kevin to order it.

Metformin is classified as an oral anti-diabetic drug used in the treatment of type 2 diabetes, typically for the overweight/obese and those with normal kidney function. While it has a focus on anti-diabetic benefits, the other benefits speak for themselves (more on that next).

Yes, as said, metformin provides more benefits than reducing blood sugar levels and helping reduce body weight. We’ve seen in studies that it can help reduce inflammation, fight cancer, and slow the progression of heart disease in dogs. Want sources? We have them!

Like many drugs, metformin for dogs can create GI upset especially if your pet has a sensitive stomach.  That’s why we always recommend that it be given with food. We generally do not recommend metformin for pets with kidney disease, as it may predispose them to a complication called lactic acidosis.

If you have questions about metformin for your dog or any other part of their health care, you are welcome to e-mail Dr. Kevin at For more complex issues or to set up a treatment plan, we can get you set up with a concierge consult.
