Amoxicillin vs. Augmentin — What's the Difference?
Edited by Tayyaba Rehman — By Maham Liaqat — Updated on May 8, 2024
Amoxicillin is a standalone antibiotic effective against various infections, while Augmentin contains amoxicillin and clavulanic acid, which broadens its efficacy by combating bacteria resistant to amoxicillin alone.

Key Differences
Amoxicillin is a penicillin-type antibiotic that works well against numerous bacterial infections. Augmentin, on the other hand, includes amoxicillin and clavulanic acid, a beta-lactamase inhibitor that expands its effectiveness.
Amoxicillin is suitable for straightforward infections like ear infections or strep throat. In contrast, Augmentin is often prescribed when infections are more complicated or resistant, such as sinusitis, as clavulanic acid prevents bacterial resistance.
Amoxicillin is a good choice for patients with uncomplicated infections needing a more targeted treatment. Augmentin is chosen when broader-spectrum antibiotic action is required due to bacterial resistance concerns.
Amoxicillin may cause common side effects like nausea and diarrhea. In comparison, Augmentin, due to its combination, may have a higher risk of gastrointestinal side effects, such as an upset stomach.
Amoxicillin is generally more cost-effective since it contains a single active ingredient. However, Augmentin can justify its higher cost for complex infections by preventing treatment failure caused by resistant bacteria.

Augmentin
An antibiotic; a semisynthetic oral penicillin (trade names Amoxil and Larotid and Polymox and Trimox and Augmentin) used to treat bacterial infections
Amoxicillin
(pharmaceutical drug) A moderate-spectrum, bacteriolytic beta-lactam antibiotic C16H19N3O5S closely related to ampicillin and with similar properties, but more readily absorbed when taken orally. It is used to treat bacterial infections caused by susceptible microorganisms.

Common Curiosities
Can Amoxicillin treat sinus infections?
Yes, amoxicillin can be effective for uncomplicated sinus infections.
Are there higher risks of side effects with Augmentin?
Yes, Augmentin may cause more gastrointestinal side effects due to its combination.
Can both antibiotics cause allergic reactions?
Yes, individuals allergic to penicillin should avoid both medications.
Can Amoxicillin or Augmentin treat viral infections?
No, neither can treat viral infections like the flu or the common cold.
What conditions are specifically treated with Augmentin?
Resistant infections like severe sinusitis, UTIs, and bronchitis are often treated with Augmentin.
Why would a doctor prescribe Augmentin instead of Amoxicillin?
Augmentin is prescribed when infections may be resistant to amoxicillin alone.
Is Augmentin suitable for children?
Yes, it's available in child-friendly forms like liquids and chewable tablets.
How does clavulanic acid enhance Augmentin's effectiveness?
Clavulanic acid inhibits beta-lactamase, preventing bacterial resistance to amoxicillin.
Is Amoxicillin available over the counter?
No, it requires a prescription due to potential misuse and bacterial resistance.
Are there dietary considerations while taking these antibiotics?
Generally, no specific restrictions, but taking them with food may reduce stomach upset.
