Tacrolimus - My vet wants my dog to take this for dry eyes. Should I try it?

Hello! Cyclosporine has been the gold standard for treating keratoconjunctivitis sicca (KCS or dry eye) in cats and dogs for years, but in clinical and field studies Tacrolimus seems to be more effective, is very well tolerated, and side effects are unlikely with Tacrolimus ophthalmic which is why it's dispensed as an ophthalmic rather than the oral formulation which can cause serious side effects. As with cyclosporine, a burning or stinging sensation may be felt but this is less common with Tacrolimus.

You should be aware that some animals with KCS resulting from abnormal activity of the immune system may need to undergo Tacrolimus therapy throughout life.

If you have further questions or concerns please feel free to post again.
