How to use gentamicin ointment:
Use gentamicin ointment as directed by your doctor. Check the label on the medicine for exact dosing instructions.
- Gentamicin ointment may be used around the eye or in the eye, as directed by your doctor. To use gentamicin ointment in the eye, first, wash your hands. Using your index finger, pull the lower eyelid away from your eye to form a pouch. Squeeze a thin strip of ointment into the pouch. After using gentamicin ointment, gently close your eyes for 1 to 2 minutes. Wash your hands to remove any medicine that may be on them. Wipe the applicator tip with a clean, dry tissue.
- To prevent germs from contaminating your medicine, do not touch the applicator tip to any surface, including the eye. Keep the container tightly closed.
- Do not wear contact lenses while you are using gentamicin ointment. Take care of your contact lenses as directed by the manufacturer. Check with your doctor before you use them.
- Gentamicin ointment is only for the eye. Do not get it in your nose or mouth.
- To clear up your infection completely, use gentamicin ointment for the full course of treatment. Keep using it even if you feel better in a few days.
- Using gentamicin ointment at the same times each day will help you to remember to use it.
