What is amoxicillin and how does it work?

Amoxicillin is a penicillin type antibiotic that is effective against many types of bacteria. Bacteria have cell walls to protect themselves from the environment and to keep the contents of their cells together. Amoxicillin prevents bacteria from forming these walls, thus impeding them from multiplying and causing infections in the body.

What does amoxicillin treat?

It is used for treating infections caused by susceptible bacteria.

  • Infections of the middle ear, nose in adults and children.
  • Infections of the tonsils, throat, and larynx (laryngitis).
  • Infections of the bronchi (bronchitis) and lungs (pneumonia)
  • Urinary tract infections (UTI)
  • Skin infections
  • Gonorrhea
  • Combined with clarithromycin (Biaxin) and lansoprazole (Prevacid) for treating H. pylori infection and duodenal ulcer disease.

Amoxicillin drug interactions

  • Probenecid decreases the renal tubular secretion of amoxicillin. Co-administration on Amoxicillin and Probenecid may result in increased and prolonged blood levels of amoxicillin.
