Infants, especially infants up to 3 months of age, may be especially sensitive to the effects of the benzocaine in this combination medicine. This may increase the chance of side effects. However, this medicine is not expected to cause different side effects or problems in older children than it does in adults.

In these cases, your doctor may want to change the dose, or other precautions may be necessary. Tell your healthcare professional if you are taking any other prescription or nonprescription (over-the-counter [OTC]) medicine.
Certain medicines should not be used at or around the time of eating food or eating certain types of food since interactions may occur.

Proper Use of This Medicine:
You may warm the ear drops to body temperature (37 °C or 98.6 °F) by holding the bottle in your hand for a few minutes before applying the drops.
- Lie down or tilt the head so that the affected ear faces up. Gently pull the earlobe up and back for adults (down and back for children) to straighten the ear canal. Drop the medicine into the ear canal. Keep the ear facing up for about 5 minutes to allow the medicine to coat the ear canal. (For young children and other patients who cannot stay still for 5 minutes, try to keep the ear facing up for at least 1 or 2 minutes.) A sterile cotton plug may be moistened with a few drops of this medicine and gently placed at the ear opening for no longer than 5 to 10 minutes to help keep the medicine from leaking out. If you have any questions about this, check with your doctor.
- To keep the medicine as germ-free as possible, do not touch the dropper to any surface (including the ear).
- Do not rinse the dropper after use. Wipe the tip of the dropper with a clean tissue and keep the container tightly closed.
If you are using this medicine to help remove earwax, the ear should be flushed with warm water after you have used this medicine for 2 or 3 days. This is usually done by your doctor. If you have been directed to flush the ear out yourself, make sure that you have learned how to do it correctly. Follow the instructions carefully.
