How should I use this medication?
This medicine is only for use in your ears. Follow the directions on the prescription label. Wash your hands with soap and water. First, carefully clean your ear(s) with a dry cotton swab. Gently warm the bottle by holding it in the hand for 1 to 2 minutes. Use as directed by your doctor or health care professional. Lie down on your side with the affected ear up. Try not to touch the tip of the dropper to your ear, fingertips, or other surface. Squeeze the bottle gently to place the prescribed number of drops in the ear canal. Stay in this position for 30 to 60 seconds, and up to 5 minutes, to help the drops soak into the ear. Repeat, if necessary, for the opposite ear. Do not use your medicine more often than directed. Finish the full course of medicine prescribed by your health care professional even if you think your condition is better.
