Eardrops May Cause Hearing Loss: Canadian Study

A new study, led by researchers at The Montreal Children’s Hospital, has revealed that certain over-the-counter earwax softeners containing the active ingredient triethanolamine polypeptide oleate condensate (10%) can cause severe inflammation and damage to the eardrum and inner ear.

The research team studied the impact of the non-prescription drug Cerumenex on hearing. In addition, overall toxicity in the outer ear and changes in the nerve cells of the inner ear were analyzed.

“Harmful effects to many of the cells were observed after only one dose,” says Dr. Melvin Schloss co-author and MCH Director of Otolaryngology. “We observed reduced hearing, severe inflammation, and lesions to the nerve cells.”

This study highlights the fact that over the counter medications still carry the risk of serious side effects. The use of such products should be discussed with your family doctor.

Unfortunately, The College of Family Physicians in Canada has reported that approximately five million Canadians (17 %) do not have a family doctor.
