From the Guidelines

For a 41-year-old female experiencing stomach discomfort from Augmentin prescribed for a sinus infection, I recommend switching to a 5-day course of antibiotics, as this has been shown to have equal efficacy and fewer adverse effects compared to a 10-day course 1. Given that the patient is already 6 days into the treatment, it would be best to stop the current Augmentin course and consider an alternative 5-day antibiotic regimen. Some key points to consider when making this decision include:

  • The recent meta-analysis of antibiotic duration for acute bacterial sinusitis reported no difference in clinical success among patients in short-course versus long-course therapy 1
  • A sensitivity analysis comparing 5 versus 10 days of therapy found no difference in outcome, but fewer adverse events in the 5-day regimen 1
  • Switching to an alternative antibiotic such as azithromycin (500 mg on day 1, then 250 mg daily for 4 more days) or doxycycline (100 mg twice daily for 5 days) would be appropriate, considering the shorter course duration
  • It's essential to inform the patient to contact her provider immediately if she experiences severe abdominal pain, persistent vomiting, or signs of allergic reaction such as rash or difficulty breathing. The patient should also be advised to take the new antibiotic with food and consider adding a probiotic supplement to minimize gastrointestinal side effects.

From the Research

Patient Complaints and Antibiotic Side Effects

  • The patient is experiencing gastrointestinal side effects from the prescribed Augmentin (amoxicillin/clavulanate) 2.
  • Amoxicillin/clavulanate is known to have a well-tolerated safety profile, but gastrointestinal side effects can occur 3.
  • The patient's complaint of the antibiotic being "heavy on her stomach" may be related to the clavulanic acid component, which is more strongly associated with gastrointestinal side effects 2.

Alternative Antibiotic Options

  • Azithromycin has been shown to be effective in treating acute ear, nose, and throat infections with fewer gastrointestinal side effects compared to amoxicillin/clavulanate 4.
  • A study comparing azithromycin, amoxicillin/clavulanic acid, and cefaclor found that azithromycin had a higher clinical efficacy and fewer adverse effects 4.
  • However, it is essential to consider the specific infection being treated and the patient's individual needs before switching to an alternative antibiotic.

Treatment Considerations

  • The patient was initially prescribed Augmentin for a sinus infection, and it is crucial to ensure that the infection is adequately treated 3.
  • The decision to switch to an alternative antibiotic or adjust the treatment plan should be based on the patient's response to the current treatment and the severity of their side effects 5.
  • Factors such as the patient's age, medical history, and potential allergies should also be considered when selecting an antibiotic 5.
