7. How it Works:

Cyclosporine binds to cyclophilin and inhibits calcineurin, which inhibits T-cell function.

8. Side Effects and/or Signs of Overdosage:

Cyclosporine is very well tolerated by pets at low doses. However, at high doses, side effects tend to be gastrointestinal (vomiting, diarrhea, and anorexia). Uncommon adverse reactions include otitis (ear infection), gingival hyperplasia, gingivitis, hepatotoxicity, anaphylactic reactions, nephropathy, and tremors.

9. Drug Interactions:

Cyclosporine is not recommended with immunosuppressive medications (like azathioprine), antacids (like famotidine), antifungals (like Griseofulvin and ketoconazole), and certain sulfa-based antibiotics. It should also be avoided with anticonvulsants (like phenobarbital) and certain heart medications (like digoxin)

10. Cautionary Statements:

Cyclosporine should be avoided in patients that have malignant neoplasia (cancer). It should be used with caution in pets with liver or kidney disease.
