Difluprednate (DFBA), sold under the brand name Durezol is a corticosteroid used to treat pain and inflammation following eye surgery. It is used as an eye drop. Those who use it should not wear contacts.
Common side effects include inflammation of the eyelids, sensitivity to light, and eye redness. Other side effects may include increased eye pressure, cataracts, slow healing, and infection. Safety in pregnancy is unclear.
Difluprednate was approved for medical use in the United States in 2008. It is available as a generic medication. In the United States 5 ml costs about 60 USD as of 2021. It was originally made from prednisolone.
