Use this medicine only as directed by your doctor. Do not use more of it, do not use it more often, and do not use it for a longer time than your doctor ordered.

This medicine is for use only in your ears. Do not get any of it into your eyes, nose, or mouth. Rinse it off right away if it does get on these areas.

To use the ear drops:

• Before applying this medicine, clean the ear canal thoroughly and dry it with a sterile cotton applicator.
• You may warm the ear drops to body temperature by holding the bottle in your hand for a few minutes. If it gets too warm, the medicine may not work properly.
• Shake the bottle well before using it.
• Wash your hands before and after using this medicine.
• Lie down or tilt the head so that the infected ear faces up. Gently pull the earlobe up and back for adults (down and back for children) to straighten the ear canal. Drop the medicine into the ear canal. Keep the ear facing up for about 5 minutes to allow the medicine to coat the ear canal. For young children and other patients who cannot stay still for 5 minutes, try to keep the ear facing up for at least 1 or 2 minutes.
• Your doctor may also insert a cotton wick into your ear soaked with the medicine. Keep it moist by adding more medicine every 4 hours. Replace the cotton wick at least once every 24 hours.
• To keep the medicine as germ-free as possible, do not touch the dropper to any surface (including the ear). Also, keep the container tightly closed. Serious damage to the ear and possible loss of hearing may result from using contaminated ear medicines.

To help clear up your infection completely, keep using this medicine for the full time of treatment, even if you feel better after the first few doses. The infection may not clear up if you stop using the medicine too soon. Do not miss any doses.
