Alfabet PF Eye Drop is a prescription medicine used for the treatment of pressure in the eyes (ocular hypertension) and glaucoma. It works by decreasing the pressure of fluid in the eye (aqueous humor), which helps in lowering the increased eye pressure. Alfabet PF Eye Drop is to be used only in the affected eye in the dose and duration as advised by the doctor. Wash your hands before using this medicine. Check the label thoroughly for directions before use. Do not skip any doses and finish the full course of treatment even if you feel better. The most common side effects include burning, irritation, itching, and redness at the application site. If these side effects persist for a longer duration, inform your doctor. In case of accidental contact with your nose or mouth, immediately rinse it off with plenty of water. Do not drive or operate heavy machinery immediately after the use of this medicine as it may cause temporary blurring of vision and may affect your ability to drive.
