Cyclosporine has been shown to be useful in the treatment of anal furunculosis (AF) and atopy in dogs.

Monitoring of cyclosporine levels during treatment may be useful.
Approx 30 days should be allowed to reach stable trough levels using combination therapy.
Approx 17 days should be allowed to reach stable trough levels using Cyclosporine alone.

Therapeutic levels of Cyclosporine about 12 hours post pill are expected to be
between 400–600 ug/L.

Sample requirement is at least 2.0 mL of whole EDTA blood.
