Has your dog eaten Anastrozole? Are you worried the Anastrozole 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 Anastrozole and whether it can make a dog sick. Let’s get started!

Dog Ate Anastrozole

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

What is Anastrozole?

Anastrozole is used to treat early breast cancer in women who have already experienced menopause. The medicine is also used in women who have experienced menopause and when their cancer has spread within the breast or to other areas of the body. Anastrozole may also be used by women who have taken other medications and had their cancer worsen.

Anastrozole is a prescription medication that’s classed as a nonsteroidal aromatase inhibitor. It works to decrease the amount of estrogen produced by the body. The drug can slow or stop the growth of many types of breast cancer that rely on estrogen to grow.

While Anastrozole is considered safe to use in humans (when used as directed), what happens if a dog eats this medication?

The good news is that if a dog eats only a small amount of this medication, he may only experience some GI upset. However, in larger amounts, Anastrozole can be toxic to dogs.

Symptoms of Anastrozole Ingestion in Dogs

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

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

Don’t wait to see if your dog’s symptoms worsen or improve; he needs treatment ASAP.

Treatment of Anastrozole Ingestion in Dogs

There are no antidotes for Anastrozole ingestion, so the vet will work to decontaminate your dog’s system. They may induce vomiting and use activated charcoal. Your fur baby may also require antacids, anti-nausea meds, and gastrointestinal protectants. The vet may also give your dog an IV with fluids to help flush the medication from your dog’s system.

The vet will also treat other symptoms as they arise. In some cases, your canine companion may need to be hospitalized until he’s in stable condition.

The prognosis is best for dogs that receive prompt medical attention after eating Anastrozole. In the future, it’s best to keep Anastrozole and other medications out of your dog’s reach. You’ll both be happier for it!
