Ciprodex is a prescription ear drop used to treat two types of bacterial ear infections: swimmer’s ear (acute otitis externa) and middle ear infections in children who have ear tubes (acute otitis media with tympanostomy tubes). It combines an antibiotic with a steroid to fight infection and reduce swelling at the same time. The brand-name version has been discontinued, but the same medication is widely available as a generic called ciprofloxacin-dexamethasone otic suspension.
The Two Conditions It Treats
Swimmer’s ear (acute otitis externa) is an infection of the outer ear canal, the passage that runs from your outer ear to the eardrum. It often develops after water gets trapped in the ear, creating a moist environment where bacteria thrive. Symptoms include ear pain that worsens when you tug on the ear, itching, redness, and sometimes drainage. Ciprodex is approved for this condition in anyone six months of age or older.
Middle ear infection with ear tubes (acute otitis media with tympanostomy tubes) occurs in children who have had small tubes surgically placed in their eardrums to prevent fluid buildup. When bacteria enter through the tube, the infection causes drainage from the ear. Ciprodex is approved for this use in children six months and older. Because the drops are delivered directly through the tube, they reach the site of infection without the child needing to take oral antibiotics.
How the Two Ingredients Work Together
The medication contains two active ingredients that tackle different parts of the problem. Ciprofloxacin, a fluoroquinolone antibiotic, kills bacteria by blocking an enzyme they need to copy their DNA. Without that enzyme, the bacteria can’t reproduce and die off. Dexamethasone, a corticosteroid, suppresses the inflammatory response that causes swelling, fluid buildup, and pain in the ear canal. Together, the antibiotic clears the infection while the steroid speeds up relief from the symptoms that make ear infections so uncomfortable.
Dosage and How to Apply the Drops
The dosage is the same for both conditions and for all ages (six months and up): four drops in the affected ear, twice a day, for seven days. That schedule applies to both children and adults.
To get the most out of the drops, a few practical steps help. Warm the bottle in your hands for a minute or two before use, since cold drops in the ear can cause brief dizziness or discomfort. Tilt the head so the affected ear faces up, or lie on your side. After placing the drops, gently press on the small flap of cartilage at the front of the ear (called the tragus) a few times to help push the liquid deeper into the canal. Stay in that position for about a minute so the drops don’t run out.
The bottle is a suspension, meaning the medication can settle at the bottom. Shake it well before each use. Finish the full seven-day course even if symptoms improve after a few days, since stopping early can allow surviving bacteria to regrow.
Who Should Not Use It
Ciprodex is designed strictly for bacterial ear infections. It should not be used for viral infections of the ear canal, including herpes simplex infections. The steroid component can actually make viral and fungal infections worse by suppressing the local immune response, so an accurate diagnosis matters before starting treatment.
Anyone with a known allergy to ciprofloxacin or other quinolone antibiotics should not use this medication. The drops are also only for the ears. They are not interchangeable with eye drops or any other formulation, even though ciprofloxacin exists in ophthalmic versions as well.
Side Effects
Because the drops are applied directly to the ear rather than taken by mouth, the medication stays mostly local and systemic side effects are rare. The most commonly reported reactions are mild ear discomfort, itching, or a feeling of fullness in the treated ear. Some people notice a temporary change in taste if the drops travel through the ear tube or eardrum perforation and reach the back of the throat.
Allergic reactions are uncommon but possible. Signs include a rash, significant swelling, or worsening pain after starting the drops. If the infection doesn’t improve after a few days of treatment, the cause may not be bacterial, and a different approach may be needed.
Generic Availability and Cost
The brand-name Ciprodex was discontinued by its manufacturer, but generic ciprofloxacin-dexamethasone otic suspension is available from multiple manufacturers. The generic contains the same active ingredients in the same concentrations. Since the brand was removed from the market, insurance plans and state Medicaid programs have generally made the generic easier to access without prior authorization. If your prescription still says “Ciprodex,” your pharmacy will fill it with the generic version.
