Has your dog eaten azathioprine? Are you worried that azathioprine will make your dog sick? If so, you’ve come to the right place. We understand it can be scary when your dog eats something like this.

We’ve gathered information about azathioprine and whether it can make a dog sick. Let’s get started!

Dog Ate Azathioprine

It is strongly recommended to contact a Pet Poison Helpline or your veterinarian.

What is Azathioprine?

Azathioprine, also known as Imuran, is a medication that treats autoimmune diseases. It’s used to treat people who have MS (multiple sclerosis) and other autoimmune conditions.

This medication is also used to treat autoimmune conditions in dogs and ferrets. It’s not usually recommended for cats, however, as it can cause adverse effects in felines. This medication is given by mouth, in a compounded liquid suspension, or injected into a vein (in the hospital).

While this medication can be safe for humans and dogs (when given as directed), what happens if a dog eats a large amount of azathioprine?

Unfortunately, azathioprine can make a dog sick. This medication can cause liver irritation that raises liver enzyme levels and may suppress the bone marrow, causing low platelet levels.

Symptoms of Azathioprine Toxicity in Dogs

You may notice these symptoms if your dog has eaten azathioprine:

If you notice any of these symptoms in your dog, call the vet immediately. This is an emergency.

Treatment of Azathioprine Toxicity in Dogs

Treatment may start with the vet working to decontaminate your dog’s system. They may do this by inducing vomiting and using activated charcoal. These methods remove the toxin from your dog’s system. In some cases, the vet may find it necessary to pump your fur baby’s stomach to get the medication out of his system.

Your canine companion may also require an IV with fluids; the fluids also work to flush the medication from your dog’s body. The vet will also treat other symptoms as they arise.

If your dog’s condition is severe, he may need to be hospitalized until he’s in stable condition.

The prognosis is best for dogs who receive prompt medical treatment after eating azathioprine. It’s best to keep this and all medications out of your dog’s reach. You’ll both be happier for it!
