Product description:

This medication is used to relieve pain and itching from certain ear conditions (e.g., middle ear inflammation with congestion and/or fluid build-up, "swimmer's ear", outer ear inflammation). Benzocaine is a topical anesthetic that helps to numb the pain and itching.

To make sure that the right amount of medication is given, and to avoid touching the ear with the dropper, have another person insert the drops if possible. To lower the risk of dizziness, hold the container in your hand for a few minutes to warm it. 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. Hold the dropper directly over the ear, and place 4 to 5 drops into the ear canal or as directed. To help the drops roll into the ear of an adult, hold the earlobe up and back. In children, hold the earlobe down and back. Keep the head tilted for about 2 minutes, or insert a soft cotton plug if so directed. Repeat for the other ear if so directed. Do not rinse the dropper. Replace the cap after use. Repeat this procedure every 1 to 2 hours as needed or as directed by your doctor.
