Ear drop

[9] Although ear drops typically contain preservatives that slow the growth of bacteria and other microorganisms, this does not offer long term protection from contamination.

The shelf life of ear drops varies with products generally needing to be discarded within 4 weeks after opening.

[10][11] With proper use and storage, ear drops should remain effective and safe until the expiration date printed in the medication package insert.

Drops should be used according to the package instructions (typically recommended maximum of 4 days) or as directed by a healthcare provider.

[6] Otitis externa, also known as swimmer's ear, is an inflammation (infectious or non-infectious) of the external auditory canal.

[16] Treatment of otitis externa is centered around antibiotic ear drops and pain control (e.g. acetaminophen, non-steroidal anti-inflammatory drugs, and opioids including oxycodone or hydrocodone).

Some studies have demonstrated that the addition of topical steroids to antibiotic ear drops provides quicker pain relief, but these results are conflicting.

If pain does not improve within 48 to 72 hours of antibiotic therapy, individuals should consult their provider to confirm the diagnosis.

[19] Ear drops work faster since the medication directly goes to the site of infection whereas oral antibiotics enter the bloodstream first.

[23] Otic analgestic-anesthetic are drops that can help alleviate swelling, pain and congestion caused by middle ear inflammation.

[24] A common over-the-counter product sold as Auralgan contained antipyrine (analgesic) and benzocaine (anesthetic).

It included 63 children who were between the ages of 3 and 17 who presented to the emergency department reporting of ear pain.

[26] There is another small study conducted in England and Wales that reported that an analgestic-anesthetics could reduce the amount of antibiotics being used in children.
