Do not swallow or inject.Do not wear contact lenses while you are using this medication. Sterilize contact lenses according to the manufacturer's directions, and check with your doctor before you begin using them again.Tilt your head back, look upward, and pull down the lower eyelid to make a pouch. Hold the dropper directly over your eye and place one drop into the pouch as directed by your doctor. Look downward, gently close your eyes, and place one finger at the corner of your eye (near the nose). Apply gentle pressure for 1 to 2 minutes before opening your eyes. This will prevent the medication from draining out. Try not to blink or rub your eye. Repeat these steps if your dose is for more than one drop.

Some ingredients in these products may interact with this medication and prevent it from working. Ask your doctor or pharmacist if you can use these eye products while using this medication and how long to wait before applying the other products. Use eye drops before eye ointments to allow the drops to enter the eye.Use this medication regularly in order to get the most benefit from it. To help you remember, use it at the same times each day. Continue using it for the full time prescribed, usually 7 to 10 days. Stopping the medication too soon may allow the bacteria to continue to grow, which may result in a return of the infection.Tell your doctor if your condition persists or worsens.
