Cyclosporine is a prescription medication given to treat atopy (allergies to airborne substances) and immune diseases, especially those affecting the blood or skin. It works by suppressing the action of certain cells in the immune system. Plus, it comes in a capsule form, so it's easy to disguise in your pet's favorite food. Customers may receive this drug under the names Optimmune, Ciclosporin, Cyclosporine A, Atopica, Neoral, Sandimmune.


Cyclosporin is used to decrease the immune system's response to a transplanted organ, and is also used for arthritis and psoriasis.

Possible Side Effects

Gastrointestinal side effects like vomiting, diarrhea and lack of appetite have been reported. Other less-common side effects may include muscle cramps, muscle weakness and change in hair. Alert your vet if you notice signs, such as facial swelling, difficulty breathing, hives, scratching, vomiting, diarrhea and pale gums, as these may be symptoms of an allergic reaction.

Drug & Food Interactions

Talk to your vet about any other drugs the pet is taking before starting Cyclosporine.


Hypertension medications may be required in recipients of kidney, liver and heart transplants treated with Cyclosporine. However, since Cyclosporine may cause high potassium levels, potassium-sparing diuretics should not be used. While calcium inhibitors can be effective agents in treating Cyclosporine-associated hypertension, they can interfere with Cyclosporine.

NOTE: For Generic Medications, picture displayed may not depict actual product. Generic medications may vary from one order to the next by size, color and shape depending on manufacturer. Customers may receive the same drug under the names Optimmune, Ciclosporin, Cyclosporine A, Atopica, Neoral, Sandimmune.

Results are usually not observed immediately and it can take several weeks to see improvement. Never stop medication abruptly or skip doses unless your veterinarian instructs you to or symptoms can recur or worsen. Your veterinarian may reduce your pets dose over time based on his/her response to treatment. Your pet's symptoms should improve over time.
