Proper Use of neomycin, polymyxin b, and bacitracin
- First, wash your hands. Tilt the head back and, pressing your finger gently on the skin just beneath the lower eyelid, pull the lower eyelid away from the eye to make a space. Squeeze a thin strip of ointment into this space. A 1-cm (approximately ⅓-inch) strip of ointment is usually enough, unless you have been told by your doctor to use a different amount. Let go of the eyelid and gently close the eyes. Keep the eyes closed for 1 or 2 minutes to allow the medicine to come into contact with the infection.
- To keep the medicine as germ-free as possible, do not touch the applicator tip to any surface (including the eye). After using neomycin, polymyxin B, and bacitracin eye ointment, wipe the tip of the ointment tube with a clean tissue and keep the tube tightly closed.
To help clear up your infection completely, keep using neomycin, polymyxin b, and bacitracin for the full time of treatment, even if your symptoms have disappeared. Do not miss any doses.
