This medication is primarily used to treat otitis externa (swimmer's ear) and related ear conditions involving pain and inflammation. It may also be used for other topical applications where both antimicrobial coverage and local pain relief are desired, such as minor skin infections with associated discomfort.
Benzalkonium chloride acts as a quaternary ammonium antiseptic, providing broad-spectrum antimicrobial activity against bacteria and some fungi. Lidocaine is a local anesthetic that blocks nerve signals in the applied area, providing temporary numbing and pain relief. Together, they address both the infectious cause and symptomatic discomfort.
For topical/otic use only; avoid contact with eyes. Should not be used on large wound areas or for prolonged periods without medical supervision. Patients with known sensitivities to anesthetics or quaternary ammonium compounds should avoid use. Medical evaluation is recommended if symptoms persist beyond a few days or worsen.
