Augmentin works through a two-part mechanism. Amoxicillin kills bacteria by inhibiting bacterial cell wall synthesis, preventing bacteria from building the protective walls they need to survive. However, some bacteria produce enzymes called beta-lactamases that can break down amoxicillin before it works.
That's where Clavulanate Potassium comes in — it acts as a beta-lactamase inhibitor, blocking these enzymes and protecting amoxicillin from being destroyed. This combination extends Augmentin's effectiveness against a broader range of bacteria, including many strains that are resistant to amoxicillin alone.

Augmentin (Amoxicillin/Clavulanate) has a findability score of 50 out of 100, meaning it can be moderately difficult to locate — especially in liquid suspension form. ASHP reports ongoing shortages of oral suspensions and some tablet strengths from multiple manufacturers as of early 2026. Tablet forms (875/125 mg and 500/125 mg) are generally easier to find than suspensions. The shortage traces back to the 2022 RSV/flu/COVID triple-demic, and recurring supply disruptions have continued through 2025 and into 2026.
If your local pharmacy is out of stock, Medfinder can help you locate nearby pharmacies that currently have Augmentin available. You may also ask your doctor about switching to an equivalent tablet strength if the suspension is unavailable.
