What is Optimmune used for?
Optimmune is used to control recurrent inflammation of the eyes specifically that which is caused by auto immune disease, where the body starts to damage its own tissue. In this case, it damages the lacrimal glands which produce tears and the eyes become dry. Dry Eye is also known as keratoconjunctivitis sicca (KCS) and this is the condition that Optimmune is used to treat. Optimmune stimulates tear production therefore lubricating the eye and reducing inflammation. The active ingredient that achieves this is cyclosporine, a drug that suppresses the immune system.

Further Information about Optimmune
Optimmune is a drug which contains the active ingredient cyclosporine. Optimmune is used to treat a condition called Keratoconjunctivitis Sicca (KCS) or “Dry Eye”. KCS is an autoimmune disease where the body’s immune system damages other tissues in the body, in this case the lacrimal glands which produce protective tears. When these tears are missing the eyes become dry and inflamed. A test called a Schirmer Tear test (STT) measures this tear production and if it is low, Optimmune can be used to stimulate the tear production. The cyclosporine in Optimmune is a drug which suppresses the immune system and so reverses the effects of the autoimmune mediated dry eye. Treatment with Optimmune can take between 10 days and 6 weeks to show an improvement but when the lacrimal glands are producing tears again the inflammation should resolve. The vast majority of cases of KCS require lifelong treatment with Optimmune but prognosis is good with continued treatment.
Optimmune is available as a white, petroleum based ointment which is applied topically to the surface of the eye. Optimmune ointment contains 0.2% cyclosporine and comes in a tube containing 3.5g of Optimmune. Optimmune is made by Intervet Schering Plough Animal Health and is a POM-V drug which means it can only be obtained from a vet or with a prescription from a vet who is looking after your pet.
Optimmune is generally a safe drug as it remains mainly in the cornea and is not absorbed into the rest of the body so its effects remain local. Even so there can be mild side effects. Mild irritation of the eye and if this persists for over a week then treatment should be stopped. Optimmune should not be used in pregnant or lactating animals as its safety in these animals has not been determined. Although the cyclosporine in Optimmune suppresses the immune system it has been shown that long term use of Optimmune does not cause an increased incidence of infections in the eye.
