Researchers at The Montreal Children's Hospital have revealed that certain over-the-counter earwax softeners can cause severe inflammation and damage to the eardrum and inner ear. The results of the study, recently published in The Laryngoscope, suggest that use of these medications should be discouraged.
"Patients often complain that wax is blocking their ears and is causing discomfort and sometimes deafness," says Dr. Sam Daniel principal investigator of the study and director of McGill Auditory Sciences Laboratory at The Children's. "Over-the-counter earwax softeners are used to breakup and disperse this excess wax. However, the effects of these medications on the cells of the ear had not been thoroughly analyzed."
