From the Guidelines
If Augmentin is ineffective for acute sinusitis, the next best antibiotic option is high-dose amoxicillin-potassium clavulanate, as it covers resistant bacteria and is a recommended choice for poor response to initial treatment. According to the study by 1, for poor response to treatment with amoxicillin or trimethoprim-sulfamethoxazole, an antibiotic should be prescribed that covers resistant bacteria, and high-dose amoxicillin-potassium clavulanate is listed as an appropriate choice. Some key points to consider in the management of acute sinusitis that is unresponsive to Augmentin include:
- Continuing antibiotic treatment for another 10 to 14 days or considering alternative antibiotic choices
- Evaluating the patient for underlying risk factors and considering consultation with an allergist-immunologist or otolaryngologist if necessary
- Reinforcing comfort and prevention measures, such as nasal saline irrigation and intranasal corticosteroids
- Considering a sinus CT scan if not already done to rule out complications or chronic sinusitis The use of broader-spectrum single agents, such as cefuroxime or cefpodoxime, with or without the addition of anaerobic coverage with clindamycin or metronidazole, may also be considered if the patient fails to improve after 21 to 28 days of initial antibiotic treatment, as noted in the study by 1.
From the FDA Drug Label
1.6 Acute Bacterial Sinusitis Moxifloxacin hydrochloride tablets are a fluoroquinolone antibacterial indicated for treating infections in adults 18 years of age and older caused by designated susceptible bacteria, in the conditions listed below: Acute Bacterial Sinusitis (1.6) To reduce the development of drug-resistant bacteria and maintain the effectiveness of moxifloxacin hydrochloride tablets and other antibacterial drugs. Moxifloxacin hydrochloride tablets should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria.
Alternative treatment options for acute sinusitis if Augmentin is ineffective include:
- Moxifloxacin (2): a fluoroquinolone antibacterial indicated for treating acute bacterial sinusitis in adults.
- Levofloxacin (3): a fluoroquinolone antibacterial indicated for treating acute bacterial sinusitis due to Streptococcus pneumoniae, Haemophilus influenzae, or Moraxella catarrhalis.
It is essential to note that the choice of alternative treatment should be based on the specific cause of the infection, patient factors, and local resistance patterns.
From the Research
Treatment Options for Acute Sinusitis
If Augmentin (amoxicillin-clavulanate) is ineffective in treating acute sinusitis, there are alternative treatment options available.
- Other antibiotics such as cefuroxime, cefpodoxime, or cefdinir can be used as alternatives 4.
- In cases of serious drug allergy, clarithromycin or azithromycin may be prescribed 4.
- Levofloxacin has been shown to be as effective as amoxicillin-clavulanate in treating acute sinusitis, with a once-daily administration and better tolerance 5.
- Moxifloxacin is also an effective treatment option, with a once-daily administration and rapid symptomatic relief 6.
Duration of Therapy
The optimal duration of therapy for acute sinusitis is unknown, but some studies suggest that a 10- to 14-day treatment course is recommended 4, 7.
- However, some evidence suggests that short-course (< or =5 days) antibiotic therapy may have equivalent or superior efficacy compared with traditional longer (10-14 days) therapies 7.
- Further research is needed to determine the optimal duration of therapy for acute sinusitis, especially in children and in adult patients with frontal, ethmoidal, and sphenoidal sinusitis 7.
Choosing the Right Treatment
When choosing the right treatment for acute sinusitis, it is essential to consider the patient's symptoms, medical history, and potential allergies.
- Images to confirm the presence of acute sinusitis are necessary in older children (> 6 years) and adults to enhance the certainty of diagnosis 4.
- The predominant bacterial species that are implicated in acute sinusitis are Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis in children 4.
- Empiric antibiotic therapy should provide adequate coverage against the most important pathogens 7.
