Proper Use
For patients using tobramycin ophthalmic solution (eye drops):
- The bottle is only partially full to provide proper drop control.
- To use:
- First, wash your hands. Tilt the head back and with the index finger of one hand, press gently on the skin just beneath the lower eyelid and pull the lower eyelid away from the eye to make a space. Drop the medicine into this space. Let go of the eyelid and gently close the eyes. Do not blink. Keep the eyes closed for 1 or 2 minutes, to allow the medicine to come into contact with the infection.
- If you think you did not get the drop of medicine into your eye properly, use another drop.
- To keep the medicine as germ-free as possible, do not touch the applicator tip to any surface (including the eye). Also, keep the container tightly closed.
- If your doctor ordered two different ophthalmic solutions to be used together, wait at least 5 minutes between the times you apply the medicines. This will help to keep the second medicine from ``washing out'' the first one.
For patients using tobramycin ophthalmic ointment (eye ointment):
- To use:
- First, wash your hands. Tilt the head back and with the index finger of one hand, press gently on the skin just beneath the lower eyelid and pull the lower eyelid away from the eye to make a space. Squeeze a thin strip of ointment into this space. A 1.25-cm (approximately ½-inch) strip of ointment usually is enough, unless you have been told by your doctor to use a different amount. Let go of the eyelid and gently close the eyes and keep them 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 tobramycin eye ointment, wipe the tip of the ointment tube with a clean tissue and keep the tube tightly closed.
To help clear up your eye infection completely, keep using tobramycin for the full time of treatment, even if your symptoms have disappeared. Do not miss any doses.
