How should I use this medicine?

Gently warm the bottle by holding it in the hand for 1 to 2 minutes. Lie down on your side with the infected ear facing upward. Try not to touch the tip of the dropper to your ear, fingertips, or other surface. Instill the correct number of drops in the ear.

Finish the full course of medicine prescribed by your doctor or health care professional even if you think your condition is better.
