For a certain degree of hearing loss in a woman patient around 48 years old, ENT specialist prescribed Bexter tablet once in the night for 30 days.No testing was done, After that, speech and hearing specialists after extensive audio testing in a specialist Insitute elicited from the patient she had ear discharge many years ago.They said there is a possible hole in the ear(?) and suggested that she plug her ears before bathing and cover both ears with cotton plug when outside and prescribed Mucolite tablets for one month twice a day. I find that Bexter is Vit B12 and Mucolite is meant for thinning viscid material. Can this patient who hepls me around the house and is not very literate,take both medicines? Will that be useful? Will there be side effects?
