Important Safety Information

Apoquel Chews

Do not use Apoquel Chewable in dogs less than 12 months of age or those with serious infections. Apoquel Chewable may increase the chances of developing serious infections, and may cause existing parasitic skin infestations or pre-existing cancers to get worse. Consider the risks and benefits of treatment in dogs with a history of recurrence of these conditions. New neoplastic conditions (benign and malignant) were observed in clinical studies and post-approval. Apoquel Chewable has not been tested in dogs receiving some medications including some commonly used to treat skin conditions such as corticosteroids and cyclosporines. Do not use in breeding, pregnant, or lactating dogs. Most common side effects are vomiting and diarrhea. Apoquel Chewable has been used safely with many common medications including parasiticides, antibiotics and vaccines. See full Prescribing Information.
