This helps reduce scratching so the skin has a chance to heal.

CYTOPOINT is an injection that your veterinarian gives your dog once every 4 to 8 weeks, as needed. 

In studies, after one injection, CYTOPOINT started controlling itch within 1 day, and kept itch controlled for a month or longer. CYTOPOINT also helped damaged skin begin to heal within 7 days

                                                  IS it SAFE?

In a clinical study, dogs receiving CYTOPOINT injections had no more side effects than dogs who received placebo injections (injections with no treatment at all). 

CYTOPOINT is safe to use in dogs of any age, and can be used with many other commonly used medications and in dogs with other diseases.

Because CYTOPOINT is a biological therapy and not a drug, it is naturally broken down and recycled by the body. It is not eliminated from the body via the liver or kidneys like most pharmaceutical drug products. This is one of the reasons CYTOPOINT can be a safe choice for your dog.

CYTOPOINT is a monoclonal antibody (mAb)* that specifically targets and neutralizes canine IL-31,† an important cytokine‡ involved in sending the itch signal to the brain in atopic dermatitis

Antibodies are substances produced by the body to fight disease ( a blood protein). 

Antibodies, also known as immunoglobulins, are Y-shaped proteins that are produced by the immune system to help stop intruders from harming the body. 

When an intruder enters the body, the immune system springs into action. These invaders, which are called antigens, can be viruses, bacteria, or other chemicals. 

When an antigen is found in the body, the immune system will create antibodies to mark the antigen for the body to destroy.

Well 'Zoetis'  (the company that makes CYTOPOINT) says YES, common sense says to urge caution.

We have NEVER injected antibodies into dogs before as a course of any type of treatment.

In fairness this is on the cutting edge of new therapies for treating disease in people and animals, but there is still much we don't know.

How about ONLY 1 study performed by the company..

Seems to me that a large multinational drug company like Zoetis could afford some, and probably in the best interest of pet safety to get some non biased research.

And WHERE is the FDA?
