Cytopoint vs. Apoquel: best allergy medicine for dogs
Your dog is scratching constantly, your vet mentioned Cytopoint or Apoquel, and now you're trying to figure out what the difference actually is before your next appointment.
Here's the short version. Both treat atopic dermatitis, the chronic itching and skin inflammation caused by environmental allergies. But they work completely differently.
Cytopoint is an injection your vet administers every four to eight weeks. It uses engineered antibodies to neutralize the proteins in your dog's body that trigger itching. No daily pills, no owner compliance issues. Studies estimate it helps in about 75% of atopic dermatitis cases.
Apoquel is a daily oral tablet that starts working within four hours. It inhibits the Janus kinase signaling pathway, which is the cellular signal that drives both itching and inflammation. It has broader anti-inflammatory effects and can be started and stopped quickly, which makes it easier to assess whether it's working. The tradeoff is it cannot be used in dogs under one year old.
Neither is universally better. The right choice depends on your dog's age, symptoms, health history, and whether they need short-term relief or long-term management. Some dogs do best on both at once.

A licensed Dutch vet can evaluate your dog's allergy symptoms and prescribe via same-day video visit in most states.
