Cyclosporine is sometimes prescribed for cats to treat certain medical conditions, particularly those related to immune system disorders. It’s commonly used to manage feline inflammatory bowel disease (IBD), which can cause chronic vomiting and diarrhea. Its mechanism involves inhibiting the immune system’s reaction, thereby aiding in the reduction of intestinal inflammation.

Understanding the Basics of Cyclosporine

Cyclosporine is derived from a fungus called Tolypocladium inflatum. Swiss researchers first isolated it in the late 1970s while exploring natural compounds with immunosuppressive properties. Its discovery revolutionized organ transplantation by significantly improving the success rates of transplant surgeries.

How Cyclosporine Works


At its core, It is an immunosuppressant, meaning it dampens the organism’s defensive response. This property is crucial in transplantation, where the body’s natural defense mechanisms can recognize a transplanted organ as foreign and mount an attack, leading to rejection.

Cyclosporine for Cats

Cyclosporine calms down the immune system in cats with skin problems. It stops specific protective cells, called T lymphocytes, from being too active, which helps ease inflammation. For allergic skin issues, it can lessen itching and make skin problems less severe.

Side Effects of Cyclosporine in Cats


It causes various side effects, including upset stomachs, such as vomiting, diarrhea, or decreased appetite; this might necessitate alterations to the dosage or cessation of the medication. Few may also develop overgrowth of the gums, leading to discomfort while eating and requiring regular dental care and monitoring.

Cyclosporine and Other Drugs

Some drugs, like certain antifungals and antibiotics, can raise cyclosporine levels in the body, potentially causing toxicity. On the other hand, drugs like rifampin or St. John’s wort can lower cyclosporine levels, requiring higher doses for effectiveness. Pairing it with additional nephrotoxic medications or immunosuppressants may also increase the likelihood of kidney impairment or infections.

Cyclosporine Dosage for Cats


The dosage depends on the patient’s condition, how severe it is, and how they react to the medicine. The type and strength of the medicine also affect dosing. For skin issues like atopic dermatitis or eosinophilic granuloma complex, the usual starting dose is 5 mg/kg once a day by mouth.

Missed Cyclosporine Doses in Cats


Missing a dose can disrupt their treatment plan, potentially affecting its effectiveness. If a dose is forgotten, it’s essential to either give it as soon as remembered or forego it if close to the next scheduled dose without doubling up. Resuming the regular dosing schedule is crucial for maintaining a stable procedure.

Cyclosporine Cost for Cats


The cost may fluctuate depending on the treatment type, dosage, and where it’s bought. Factors affecting cost include whether it’s a brand-name or generic version, the formulation (like oral solution or capsules), and the concentration. Your vet’s prescription and the length of cure also impact the cost.

Storing Cyclosporine


Proper storage is crucial to keeping it practical. Follow the manufacturer’s instructions, especially for your type and brand. Store it away from light in a dark container or original packaging. Store at room temperature, avoiding places with significant temperature changes or high humidity.

Veterinary Check-ups

Owners should work closely with their veterinarian to diagnose and manage dermatological conditions in their pets and follow the veterinarian’s instructions carefully when administering remedies. Routine veterinary examinations and surveillance are imperative to guarantee the safety and efficacy of procedures and address any concerns or changes.

Cyclosporine and Kidney Transplants


Cyclosporine is a cornerstone medication in kidney transplant procedures. It suppresses the defensive response, helping prevent the body from rejecting the transplanted kidney. Alongside other immunosuppressants, it significantly improves the success rates of transplants, allowing recipients to enjoy extended and improved quality of life.

Ocular Uses of Cyclosporine

It has found applications in ophthalmology, particularly in treating specific eye conditions like dry eye disease (keratoconjunctivitis sicca) in humans and animals, including cats. Its anti-inflammatory properties help alleviate symptoms by reducing inflammation on the eye’s surface and improving tear production, leading to increased comfort and better ocular health.

Administration of Medication


When storing, keep it out of reach of pets and children, as ingestion can lead to adverse effects. Additionally, always inspect the expiration date before administering it to ensure potency. Contact your veterinarian promptly if there are concerns about the medication’s efficacy.

Research Possibilities

Apart from its known uses, it is being studied for its potential in various areas, such as protecting the brain and heart and treating cancer. Its many ways of working make it helpful in studying and treating different health problems.

Long Track Record


It has a long track record, having been in clinical use for several decades, and a well-established safety profile when used appropriately. It has undergone extensive testing and research, contributing to our understanding of immunosuppressive therapy and its medical applications.
