Emergencies can happen at any time, so it’s best to be prepared and know what to do if an emergency occurs. Talking with your veterinarian is a crucial part of being informed and prepared to handle emergencies.

Low blood sugar (hypoglycemia)

The most common side effect experienced with insulin therapy is hypoglycemia. Hypoglycemia can be caused by:

  • Giving too much insulin.
  • Missing or delaying food.
  • Change in food, diet, or amount fed.
  • Infection or illness.
  • Change in the body’s need for insulin.
  • Diseases of the adrenal, pituitary, or thyroid glands, or progression of liver or kidney disease.
  • Interaction with other drugs (such as steroids).
  • Change (increase) in exercise.

Signs of hypoglycemia may occur suddenly and can include:

  • Weakness
  • Depression
  • Behavioural changes
  • Muscle twitching
  • Vocalisation
  • Anxiety
  • Seizures
  • Coma
  • Death

What to do

If your pet is conscious, rub a tablespoon of corn syrup on his or her gums. When your pet is able to swallow, feed him or her a usual meal and contact your veterinarian. If your pet is unconscious or having a seizure, this is a medical emergency. Contact your veterinarian right away.

In the meantime, you should immediately treat your pet rather than delay management. Pour a small amount of a sugar solution (e.g., corn syrup) onto your finger and then rub the sugar solution onto your pet’s gums. The sugar is absorbed very quickly and your pet should respond in 1 to 2 minutes. The sugar solution should never be poured directly into your pet’s mouth since there is a risk that the solution will be inhaled into the lungs. Once your pet has responded to the sugar administration and is sitting up, it can be fed a small amount of its regular food. Once the pet has stabilised, it should be transported to your veterinarian for evaluation.
