Yes, Apoquel (oclacitinib) can cause elevated liver enzymes in some dogs, indicating potential liver stress, though serious liver failure is rare in dogs but a severe risk in cats if ingested, necessitating regular bloodwork monitoring for dogs on long-term treatment, especially for liver/kidney function. While Apoquel is generally considered safe for dogs with proper monitoring, signs like lethargy, vomiting, or appetite loss warrant immediate vet attention, and it's crucial to keep it away from cats, as even small amounts can cause severe liver/kidney damage and death.

Does Apoquel cause liver problems in dogs?

There are no known effects of Apoquel® on organs such as the kidneys and liver. Some dogs have been treated with Apoquel for more than five years without any problem, and we do not expect there will be long-term problems.

How long can dogs stay on Apoquel?

Apoquel is not FDA approved to use twice daily longer than 14 days.

The level of elevation of the liver enzymes may be minor or more pronounced, depending on how much of the liver is affected. Temporary conditions resulting in the elevation may often disappear through such changes as diet and exercise, or once an underlying medical issue has been treated.

Can dehydration cause liver enzymes to be elevated?

Yes, dehydration can cause elevated liver enzymes. The liver needs plenty of fluids to function properly. Dehydration (lack of enough fluids in the body) can increase the risk of liver damage and elevated liver enzymes.
