Vetsulin (Insulin) For Dogs

(redirects here from vetsulin)

This article contains information about insulin for dogs (sold as Vetsulin), the dosage, side effects, safety guidelines and more.

Vetsulin is an FDA-approved medication for treating pets suffering from diabetes. The medicine is able to control blood glucose levels in dogs by supplementing the body when the pancreas is not producing enough insulin. You should never begin treatment with Vetsulin without first consulting with your vet. Administering Vetsulin without veterinary guidance and approval could be dangerous.

Insulin dosage for dogs

Vetsulin can be administered either by using a U-40 insulin pen, or a VetPen. You should inject the medicine around 2 to 5 cm from the dorsal midline, which will fall roughly around the middle of your pet’s back. The vet will talk you through the process of injection until you are comfortable with it.

The typical starting dose is around 0.5 IU/kg body weight (which translates to roughly 0.22 IU/lb) administered once a day with (or just after) a meal. During check-ups the vet may decide to alter the dosage based on how your dog has reacted and the improvement of your pet’s condition. The vet may also decide to switch your pet over to a twice-a-day dosage routine, with each dose being roughly ¾ of the once-a-day dosage.

It is recommended that you round the dosage down to the nearest whole figure, and round your pet’s weight down to the nearest whole kg to avoid hypoglycemia.

Is insulin safe for dogs?

Diabetes is a condition which effects many dogs worldwide, and Vetsulin is one of the only FDA-approved treatments available. Using Vetsulin without first consulting with the vet could be dangerous, but when used correctly could save your pet’s life.

Safety precautions

  • Never begin treating your dog with Vetsulin without veterinary approval
  • Monitor your pet closely when he/she first begins treatment
  • Round the dosage and your pet’s weight down to the nearest whole figure
  • Do not administer Vetsulin to dog’s with pork allergy
  • Notify the vet of all other medication your pet is taking
  • Notify the vet of all other medical problems your pet suffers from
  • Notify the vet if your dog is pregnant, nursing or breeding

Because Vetsulin sources insulin from pigs, dogs with a pork allergy could develop severe side effects. Never give a new substance to your pet without first checking it over with your vet.
