How should this medicine be used?
Tobramycin ophthalmic comes as a solution (liquid) to instill into the eyes and as an eye ointment to apply to the eyes. The eye drops are usually applied every 4 to 8 hours, and the ointment is usually applied two to four times a day.

Do not use more or less or use it more often than prescribed by your doctor.
To instill the eye drops, follow these steps:
- Wash your hands well with soap and water.
- Check the dropper tip to make sure it is not chipped or cracked.
- Avoid touching the tip of the dropper against your eye or anything else; Eye drops and droppers must be kept clean.
- While tilting your head back, lower the lower lid of your eye with your index finger to form a pocket.
- Hold the dropper (tip down) with the other hand, as close to the eye as possible without touching it.
- Rest the remaining fingers of that hand against your face.
- While looking up, gently squeeze the dropper so that a single drop falls into the pocket formed by the lower eyelid. Remove your index finger from the lower eyelid.
- Close your eye for 2 to 3 minutes and tilt your head down as if looking at the ground. Try not to blink or squeeze your eyelids.
- Place a finger over the tear duct and apply gentle pressure.
- Wipe any excess fluid from your face with a tissue.
- If you are using more than one drop in the same eye, wait at least 5 minutes before instilling the next drop.

What should I know about storage and disposal of this medication?
Keep this medicine in the container it came in, tightly closed, and out of the reach of children. Store at room temperature and away from excess heat and moisture (not in the bathroom).
Unnecessary medications must be disposed of in special ways to ensure they cannot be consumed by pets, children, and others. However, you should not flush this medicine down the toilet. Instead, the best way to dispose of your medications is through a drug take-back program. Talk to your pharmacist or contact your local garbage / recycling department to find out about take-back programs in your community. Check out the FDA drug safe disposal website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.
It is important to keep all medicines out of the sight and reach of children, since many containers (such as those containing weekly pills and those for eye drops, creams, patches and inhalers) are not child-resistant and small children can easily open them. To protect young children from poisoning, always close the safety caps and immediately place the medicine in a safe place, one that is upright and out of their sight and reach. http://www.upandaway.org
