AUGMENTIN - a patient's guide


Augmentin is a commonly prescribed antibiotic. This article discusses its uses and side effects.

Drug name: Amoxycillin and clavulanic acid (Co-amoxiclav)

Use: Antibiotic - broad spectrum penicillin

This medicine contains two active ingredients that extends the antibiotic activity to a wider range of infections. The rationale behind this is due to the addition of clavulanic acid which has special activity against beta-lactamase producing bacteria. These infections can cause resistance against certain penicillin antibiotics including amoxycillin by itself.

  • Bowel inflammatory conditions
  • Pregnancy

Side effects:


stomach upset
