Augmentin Dosing for Tonsillitis

First-Line Treatment Approach

The American Heart Association recommends amoxicillin alone as the preferred initial treatment for Group A Streptococcal tonsillopharyngitis, not Augmentin 1, 2
Penicillin V is an acceptable alternative for 10 days, with dosing of 250 mg 2-3 times daily for children <27 kg and 500 mg 2-3 times daily for children ≥27 kg and adults 2
The addition of clavulanate does not improve outcomes for uncomplicated streptococcal pharyngitis and unnecessarily increases cost and side effects 2

Augmentin should be reserved for treatment failures after initial amoxicillin or penicillin therapy 1
Augmentin is also recommended for chronic carriers of Group A Streptococcus who have failed first-line therapy 1

The standard dose of Augmentin for pediatric patients is 40 mg amoxicillin/kg/day divided into three doses (maximum 2,000 mg amoxicillin per day) for 10 days 1
The maximum daily dose of Augmentin should not exceed 2,000 mg of amoxicillin component per day, regardless of weight 1

The American Heart Association recommends completing the full 10-day course of antibiotics even if symptoms resolve earlier to prevent recurrence, complications, and rheumatic fever 1, 2
Treatment duration for tonsillitis should be 10 days to ensure adequate eradication and prevent rheumatic fever 2
Assess response after 72 hours - if symptoms worsen or fail to improve, consider treatment failure 1

For patients with penicillin allergy, cephalexin is a recommended alternative for 10 days, avoiding immediate (Type I) hypersensitivity 1, 2
Clindamycin, azithromycin, and clarithromycin are also alternative options, with specific dosing recommendations 2
Macrolides have higher bacteriologic failure rates (20-25%) and should be used cautiously in areas with known resistance 6
