What Is It?: Ophthalmic tobramycin (toe-bra-MYE-sin) is used in the eye to treat bacterial infections of the eye. Tobramycin works by killing bacteria. Ophthalmic tobramycin may be used alone or with other medicines for eye infections
How 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.

Possible Side Effects: Check with your doctor immediately if any of the following side effects occur: Less common: Itching, redness, swelling, or other sign of eye or eyelid irritation not present before use of this medicine. Symptoms of overdose: Increased watering of the eyes; itching, redness, or swelling of the eyes or eyelids;  painful irritation of the clear front part of the eye. Other side effects may occur that usually do not need medical attention. These side effects may go away during treatment as your body adjusts to the medicine. However, check with your doctor if either of the following side effects continues or is bothersome: Less common: Burning or stinging of the eyes

Storage: Keep in the original container. Keep out of the reach of children and pets. These drops must be kept refrigerated at all times. They may have a faint odor. If they are deteriorating the odor will become more pronounced. This is not harmful but it does indicate that they may be less potent than when fresh. Under best conditions the drops have a stability dating of 15 days.

Note: If you miss a dose take it as soon as you remember it. However, if it is almost time for the next dose, skip the missed dose and continue with the regular schedule. Do not take a double dose to make up for the missed one.
