what is restasis used for

Restasis is a brand-name eye drop that is used to treat chronic dry eye in adults and some children. Chronic dry eye occurs when the eyes do not make enough tears or the tears they make do not work well enough to keep moisture in the eyes. This condition is believed to be caused by inflammation affecting the ability of the eyes to make tears. Restasis contains the active drug cyclosporine, which is an immunosuppressant that can increase tear production that has been reduced by inflammation in the eye(s). Restasis works by reducing inflammation in the tear glands, helping to prevent further damage and improving the bodys natural ability to make tears. It is important to note that Restasis is used not to produce tears or wetness in the eyes, but rather to prevent further damage to the tear glands. Restasis is available as a liquid emulsion (an oily liquid mixture) that is used as eye drops. It may take several weeks for Restasis treatment to produce a therapeutic effect, and it may even take up to 6 months for the maximum benefit to be felt. Restasis should not be used if you are allergic to any of the ingredients, and it should not be used while wearing contact lenses.
