# Amoxicillin
## Overview
Amoxicillin is a semi-synthetic penicillin antibiotic with an expanded spectrum of activity, including activity against *Streptococcus pneumoniae*, *Haemophilus influenzae*, and *Escherichia coli*. It is bactericidal via inhibition of bacterial cell wall synthesis.
## Primary Indications
Acute otitis media, streptococcal pharyngitis, sinusitis, community-acquired pneumonia, and *Helicobacter pylori* eradication (in combination).
## Adult Dosing
* **Mild to Moderate Infections:** 500 mg every 12 hours or 250 mg every 8 hours.
* **Severe Infections:** 875 mg every 12 hours or 500 mg every 8 hours.
* **Max Dose:** Generally up to 3 g/day for routine infections; higher doses (up to 1 g TID) may be used for pneumonia or resistant *S. pneumoniae*.
## Pediatric Dosing
* **Standard Infections:** 20–40 mg/kg/day divided every 8 hours OR 25–45 mg/kg/day divided every 12 hours.
* **Acute Otitis Media (high-dose):** 80–90 mg/kg/day divided every 12 hours.
* **Max Dose:** 500 mg per dose (or up to 875 mg per dose per current clinical guidelines for high-dose regimens).
## Dose Adjustments
* **Renal Impairment:** Adjust for CrCl < 30 mL/min. If CrCl 10–30 mL/min, 250–500 mg q12h. If CrCl < 10 mL/min, 250–500 mg q24h.
* **Hepatic Impairment:** No specific adjustment required.
## Contraindications
History of severe allergic reaction (anaphylaxis) to any penicillin or cephalosporin (due to potential for cross-reactivity).
## Adverse Effects
Diarrhea, nausea, vomiting, skin rash (non-allergic morbilliform rash common in patients with mononucleosis), and potential *Clostridioides difficile*-associated diarrhea.
## Key Drug Interactions
* **Probenecid:** Increases serum concentrations of amoxicillin by decreasing renal tubular secretion.
* **Warfarin:** May increase INR; monitor closely when initiating or discontinuing antibiotics.
* **Oral Contraceptives:** Potential for decreased efficacy (controversial, but back-up contraception is often recommended).
## Monitoring
Monitor for signs of hypersensitivity (rash, pruritus, anaphylaxis), stool frequency/consistency, and resolution of infection symptoms. Long-term use requires periodic renal/hepatic function assessment.
## Clinical Pearls
* Amoxicillin is stable in the presence of gastric acid and absorption is unaffected by food.
* The non-allergic "ampicillin rash" is common in pediatric patients with Epstein-Barr virus; it does not necessarily represent a true IgE-mediated allergy.
* Always ensure the diagnosis is bacterial, not viral, to promote antibiotic stewardship.
