How should I use carbamide peroxide?

Use this medication exactly as directed on the label, or as prescribed by your doctor. Do not use it in larger amounts or for longer than recommended.

This medication comes with patient instructions for safe and effective use. Follow these directions carefully. Ask your doctor or pharmacist if you have any questions.

The usual dose of this medication for children is 1 to 5 drops per ear twice daily. The usual dose for adults is 5 to 10 drops per ear twice daily. Follow your doctor's instructions. Carbamide peroxide may be used for up to 4 days, unless your doctor has told you otherwise.

To use the ear drops, first remove the cap from the dropper bottle. Lie down or tilt your head with your ear facing upward. Pull back on your ear gently to open up the ear canal. Hold the dropper upside down over your ear canal and drop the correct number of ear drops into the ear.

You may hear a bubbling sound inside your ear after putting in the drops. This is caused by the foaming action of carbamide peroxide, which helps break up the wax inside your ear.

After using the ear drops, stay lying down or with your head tilted for at least 5 minutes. You may use a small piece of cotton ball to plug the ear and keep the medicine from draining out. Follow your doctor's instructions about the use of cotton.

Do not place the dropper tip into your ear, or allow the tip to touch any surface. It may become contaminated.

Wipe the tip of the medicine bottle with a clean tissue. Do not wash the dropper tip.

Carbamide peroxide may be packaged with a bulb syringe that is used to flush out your ear with water.

When filling the bulb syringe, use only warm water that is body temperature (no warmer than 98 degrees F). Do not use hot or cold water.

Hold your head sideways with your ear over a sink or bowl.

Gently pull your ear lobe back and downward to open up the ear canal. Place the tip of the bulb syringe at the opening of your ear canal. Do not insert the tip into your ear.

Squeeze the bulb syringe gently to release the water into your ear. Do not squirt the water with any force into your ear, or you could damage your ear drum.

Remove the syringe and allow the water to drain from your ear into the sink or bowl.

Do not use carbamide peroxide for longer than 4 days in a row. Call your doctor if your ear symptoms do not improve after treatment, or if they get worse.

Clean the bulb syringe by filling it with plain water and emptying it several times. Do not use soap or other cleaning chemicals. Allow the syringe to air dry.

Store the medication and the bulb syringe at room temperature away from moisture, heat, and direct light.
