Many dogs have atopic dermatitis.  In fact, it is the most common allergic skin disease among canines.  Some studies estimate the incidence may be as high as 15%*  Puppies with a parent, grandparent, sibling or other relative with atopic dermatitis are likely to have atopic dermatitis as well.  However, even the dogs that don't have the condition in their family may develop atopic dermatitis too.
 

Most cases begin between the ages of 6 months and 3 years.  It is common for the disease to begin as a seasonal condition and progress to a year-round problem over time.
 

As with all drugs, side effects may occur.  In a field study, the most common side effects were gastrointestinal signs.  Gingival hyperplasia and papillomas may also occur during the initial dosing phase.  ATOPICA is not for use in dogs with a history of malignant neoplasia, or with a   demonstrated hypersensitivity to Cyclosporine A.
