If your ears feel itchy and full, you may be suffering from a buildup of wax in the ear canals. Carbamide peroxide, an over-the-counter medication, can be helpful in softening and removing excessive ear wax. Carbamide peroxide is sold under multiple brand names, including Debrox. The medication is a liquid that is applied directly to the ear canal. While Debrox can be helpful in removing extra ear wax, it does not work instantly and must be used for up to four days for best results.

Wash and dry your hands before using Debrox.

Lie down or angle your head to the side, allowing the ear you are treating to face the ceiling. Drugs.com suggests pulling the earlobe up and back to straighten the ear canal in adults and pulling the earlobe down and back to straighten the ear canal in children.

Open the Debrox solution and remove the eyedropper 1. Depress the bulb of the eyedropper and place it in the liquid. Slowly loosen your grip on the bulb after placing it in the solution. As the bulb returns to its normal state, the eyedropper will fill with the medication.

Hold the eyedropper over the ear and drop 5 to 10 drops of Debrox in the ear.

Keep your head in the same position for several minutes to allow the medication to penetrate the ear canal.

Return the eyedropper to the Debrox bottle and wash your hands. Keep the medication out of the reach of children. HealthSquare.com notes that the medication may be harmful if swallowed.

Repeat the procedure on the other ear. Use Debrox twice each day for four days. At the conclusion of the fourth day, fill a rubber bulb ear syringe with warm water and gently flush the ear canal. Flushing the ear can help remove loosened pieces of ear wax.
