Cyclosporine should not be administered in animals with a known allergy or hypersensitivity to the drug. Cyclosporine should not be used in animals with certain blood disorders, kidney impairment, or stomach ulcers. Long term use of this drug may increase the risk for certain cancers such a lymphoma. Cyclosporine may interact with other medications. This should be discussed with a veterinarian. Cyclosporine should be administered with caution in animals that are pregnant or nursing. Emergency veterinary care should be sought if an animal experiences any unusual symptoms.


Cyclosporine tablets, injection, and ophthalmic solution should be stored in a tight, light-resistant container and kept at room temperature.

A typical dose range for Cyclosporine is 5 mg/kg (3.3-6.7 mg/kg) PO once daily for 30 days for the treatment of atopic dermatitis in dogs weighing at least 1.8 kg. Dose may vary in different species, when the drug is given by a different route or concurrently with other medications, and with regards to a patient's age, breed, and health status.

If a dose is missed, it should be administered as soon as possible. If it is almost time for the subsequent dose, the missed dose should be skipped and the normal administration schedule resumed. Two doses of Cyclosporine should not be administered at the same time.
