From the Guidelines
I would consider changing the antibiotic for this patient to penicillin or amoxicillin, as these are the recommended treatments for Group A streptococcal pharyngitis, according to the Infectious Diseases Society of America guidelines 1. Since the patient developed sore throat and tonsil pain after a week of Augmentin (amoxicillin-clavulanate) treatment for an ear infection, this suggests either treatment failure, a new infection, or possibly a non-bacterial cause. A reasonable approach would be to switch to penicillin or amoxicillin, as these have been shown to be effective in treating GAS pharyngitis, with penicillin being the treatment of choice due to its proven efficacy, safety, and low cost 1. Before changing antibiotics, it would be important to examine the patient to determine if this is bacterial tonsillitis, viral pharyngitis, or possibly post-nasal drip from the original infection. A rapid strep test or throat culture may help guide therapy, as recommended by the guidelines 1. The change in symptoms could indicate that the original pathogen was resistant to Augmentin or that a new pathogen has emerged. If the patient has developed a rash along with the sore throat, this could represent an allergic reaction to Augmentin rather than treatment failure, which would definitely warrant changing the medication. It's also worth noting that the patient's symptoms may be due to a viral infection, in which case antibiotic treatment would not be effective, and supportive care would be the best course of action. In any case, the decision to change antibiotics should be based on a thorough evaluation of the patient's symptoms and medical history, as well as the results of any diagnostic tests, such as a rapid strep test or throat culture 1.
Some key points to consider when changing antibiotics include:
- The patient's medical history and allergy status
- The results of any diagnostic tests, such as a rapid strep test or throat culture
- The potential for antibiotic resistance or side effects
- The need for supportive care, such as pain management and hydration, regardless of the underlying cause of the symptoms. It's also important to note that the guidelines recommend a 10-day course of oral antibiotics for the treatment of GAS pharyngitis, and that penicillin and amoxicillin are the preferred treatments due to their efficacy, safety, and low cost 1.
In terms of specific treatment options, penicillin or amoxicillin would be reasonable choices, with dosages and durations as follows:
- Penicillin: 250-500 mg orally four times a day for 10 days
- Amoxicillin: 500-1000 mg orally three times a day for 10 days. It's also worth noting that azithromycin or clindamycin may be considered as alternative treatments, especially in cases where the patient is allergic to penicillin or amoxicillin, or where there is concern for resistant organisms 1.

From the Research
Patient's Condition
- The patient had an ear infection 1 week ago and was treated with Augmentin.
- The patient is now experiencing a sore throat and tonsil pain.
Treatment Options
- According to 2, azithromycin may be a more effective treatment option for acute ENT infections, including tonsillopharyngitis, compared to amoxicillin/clavulanic acid.
- 3 suggests that amoxicillin + clavulanic acid EXPRESS in the form of dispersible tablets may have a higher safety profile and therapeutic efficacy compared to film-coated tablets in the treatment of acute streptococcal tonsillopharyngitis.
- 4 compares the efficacy of oral clindamycin with oral amoxicillin/clavulanic acid in the treatment of acute recurrent pharyngotonsillitis caused by group A beta-hemolytic streptococci, and finds that both treatments have comparable rates of bacteriologic eradication and clinical cure.
Considerations for Changing Medication
- If the patient's sore throat and tonsil pain are caused by a bacterial infection, changing the medication to a more effective option such as azithromycin or clindamycin may be considered.
- However, if the patient's symptoms are caused by a viral infection, antimicrobial treatment may not be necessary, and supportive management with analgesia and hydration may be sufficient, as suggested by 5.
- Local therapy, such as the use of the drug Doritricin, may also be effective in treating patients with acute tonsillopharyngitis, as shown in 6.
