Can relieve allergies in humans but are often not effective at reducing allergic itch in dogs.1,2
Can put your dog at risk for progression of allergic itch and secondary skin infection because they don’t treat the underlying cause, and the itch continues.
Offer little or no benefit in treating flare-ups in the majority of dogs.3
50% of dog owners reported side effects with steroids.4
Can cause side effects such as excessive drinking and urinating, increased appetite,5 and behavior changes, such as increased anxiety, even when used short term.6
In a 10-year safety review, the most common individual side effects reported with Apoquel were vomiting, diarrhea, lethargy, anorexia, and bloodwork changes.7,8
IMPORTANT SAFETY INFORMATION: Do not use Apoquel or Apoquel Chewable in dogs less than 12 months of age or those with serious infections. Apoquel and 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 and Apoquel Chewable have 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 and Apoquel Chewable have been used safely with many common medications including parasiticides, antibiotics and vaccines. See full Prescribing Information.
INDICATIONS: Control of pruritus (itching) associated with allergic dermatitis and control of atopic dermatitis in dogs at least 12 months of age.
