Introduction
F-Lon belongs to a group of medicines called steroids. It is used to treat redness and swelling in the eyes that may be due to infection or allergy. It reduces swelling, itching, and soreness after any eye injuries or eye surgery.
F-Lon should be used in the dose and duration as directed by your doctor. Never use it if the seal is broken before you use it for the first time. Wash your hands thoroughly before applying the medicine. Make sure you remove contact lenses if you wear them and wait for at least 15 minutes before putting them back. Continue using it regularly to get the most benefit from it.

Mode of Action
Fluorometholone suppresses the migration of polymorphonuclear leukocytes and reversal of increased capillary permeability thus decreasing inflammation.
