  • 8 drops to wick (in affected ear) for first dose, then 4 drops twice a day for 7 more days

    Prior to instilling Xtoro in the ear canal, you should warm the solution by holding the container in your hands for 1 to 2 minutes. It is important to warm the solution prior to instilling in the ear canal, as cold solution may cause dizziness. After the solution is sufficiently warmed, shake the container well before instilling the medication into your ear canal.

    Lie down with the affected ear up. After instilling the drops into the ear, it is important to stay in the position for 60 seconds to allow enough time for the medication to sufficiently penetrate the ear canal.
