Removal of ear wax

Wax is a normal bodily secretion which provides a protective film on the meatal skin and need only be removed if it causes deafness or interferes with a proper view of the ear drum. Syringing is generally best avoided in young children, in patients with a history of recurrent otitis externa, a history of ear-drum perforation, or previous ear surgery.

Dose and Administration: should only be applied to the ear canal. With the head tilted, fill the ear with Waxsol using the dropper provided. On the next night apply Waxsol again as before.
