Combination of Augmentin and Ciprofloxacin for Severe Otitis Media and Otitis Externa in Diabetic Patients
Yes, Augmentin (amoxicillin-clavulanate) and ciprofloxacin should be combined for treatment of severe otitis media and otitis externa in diabetic patients, as this combination provides comprehensive coverage against the most common pathogens while addressing the higher risk of complications in this population. 1
Rationale for Combination Therapy
- Diabetic patients with severe otitis media and concurrent otitis externa require both topical and systemic antibiotics, as topical therapy alone is insufficient for severe otitis media, while systemic antibiotics alone may not achieve adequate concentrations in the external ear canal 1
- The combination addresses both middle ear infection (otitis media) and external ear canal infection (otitis externa) simultaneously, which is particularly important in diabetic patients who are at higher risk for complications 1, 2
- Diabetic patients are more susceptible to necrotizing otitis externa, an aggressive infection that requires more intensive antibiotic coverage 3, 1
Recommended Regimen
- Topical therapy: Ciprofloxacin otic drops for direct treatment of the external ear canal 1, 2
- Systemic therapy:
Special Considerations for Diabetic Patients
- Diabetic patients should NOT have their ear canals irrigated to remove debris, as this may predispose them to necrotizing otitis externa 3
- Instead, atraumatic cleaning with aural suctioning under microscopic guidance is recommended 3, 1
- Careful monitoring for signs of necrotizing otitis externa is essential, including persistent pain, granulation tissue at the bone-cartilage junction, or cranial nerve involvement 3, 2
- Pseudomonas aeruginosa is isolated from exudate in more than 90% of cases of necrotizing otitis externa, making anti-pseudomonal coverage crucial 3, 1
Administration Guidelines
- Before administering ear drops, the ear canal should be cleared of inflammatory debris and obstructing cerumen to ensure medication reaches infected tissues 3, 2
- For proper administration of ear drops:
- Position the patient with the affected ear upward
- Pull the pinna down and back (for children) or up and back (for adults)
- Allow drops to run along the side of the canal until filled
- Patient should remain in this position for 3-5 minutes 3
- If the ear canal is edematous, a wick may be placed to facilitate drug delivery 3
Duration of Therapy
- Complete the full course of therapy even if symptoms resolve early 2
- For diabetic patients with severe infection, a longer course may be necessary to prevent recurrence 1, 4
- Monitor response to therapy with regular follow-up visits 1, 2
Potential Concerns with This Combination
- While resistance to ciprofloxacin is developing in some Pseudomonas strains, it remains an effective option for most cases 6, 7
- Gastrointestinal side effects may occur with both medications, but are generally mild and well-tolerated 5
- Drug interactions should be monitored, particularly with ciprofloxacin which can interact with several medication classes 2
Monitoring and Follow-up
- Reassess within 48-72 hours if symptoms worsen or fail to improve 1, 2
- Monitor for signs of necrotizing otitis externa, including:
- Persistent severe pain
- Granulation tissue in the ear canal
- Facial nerve or other cranial nerve involvement 3
- For diabetic patients, ensure strict glycemic control as part of management 4
By combining Augmentin and ciprofloxacin, clinicians can provide comprehensive coverage against the most common pathogens involved in severe otitis media and otitis externa in diabetic patients, while addressing the higher risk of complications in this vulnerable population.
