(KAR-buh-mide purr-OX-ide)

COMMON BRAND NAME(S): Auro, Debrox, Murine Earwax Drops


This medication is used to treat earwax buildup by softening, loosening, and removing the earwax.

How To Use

Apply this medication into the ear, usually twice daily, or as directed by your doctor. Do not use this medication for more than 4 days. For accuracy and to avoid contamination, have another person insert the drops if possible. To apply ear drops, wash your hands first. To avoid contamination, do not touch the dropper tip or let it touch your ear or any other surface. Lie on your side or tilt the affected ear upward. Place the dropper directly over the ear and instill the recommended, or prescribed amount of drops. To help the drops roll into the ear (for adults) hold the earlobe up and back or (for children) hold the earlobe down and back. Keep the head tilted for about two minutes or insert a soft cotton plug if so directed. If there is any wax remaining after treatment it may be removed by gently rinsing the ear with warm water or using a soft rubber bulb ear syringe. Consult your doctor or pharmacist about the safe use of an ear syringe. Do not rinse the dropper. Replace the dropper cap after use.

Side Effects

Ear drainage, ear pain, irritation or rash in the ear, or dizziness may occur. If any of these effects persist or worsen, notify your doctor. This medication may cause a crackling sound in the ears. This harmless effect is temporary and due to the medicine foaming and loosening the earwax. If you notice other effects not listed above, contact your doctor or pharmacist.
