Bimatoprost is a prostaglandin analog used for reducing high eye pressure in glaucoma and ocular hypertension and cosmetically for increasing eyelash growth. It works by enhancing the outflow of fluid from the eye, thereby lowering pressure in the eyes. Common side effects include eye redness, itching, dryness, and darkening of the eyelid skin or iris. Taking Bimatoprost with other eye drops without medical advice can increase irritation or reduce effectiveness. People with eye infections, uveitis, or prior eye surgery complications should avoid it. Overuse may cause permanent color change of the iris, excessive eyelash growth, and vision disturbances.
