The injured eye should be treated with Careprost eye drops as prescribed by a physician, usually once a day in the evening. The appropriate dosage and duration of treatment should be determined by a physician, as these factors are dependent on the patient's condition and medication reaction. To administer the eye drops, make a tiny pocket with the lower eyelid by pulling down on it while tilting the head back slightly. To prevent the liquid from draining into the tear duct, gently place a finger on the inner corner of the eye for approximately one minute. In the event that you get an allergic response, head straight to the emergency room that is closest to you. Chest tightness, swelling, hives, rashes, and trouble breathing or swallowing are all common symptoms of this kind of reaction.
