What is Himox® used for?

Himox® (amoxicillin) is part of a class of antibiotics known as penicillins. Penicillins work by binding to penicillin-binding proteins (PBPs) that are embedded on certain bacterial cell walls. This binding prevents normal crosslinking and results in a weakened cell wall that ruptures and kills the bacteria.

It is a broad-spectrum antibiotic mainly indicated to treat the following bacterial infections:

  • Upper and lower respiratory tract infections, including ear, nose and throat infections (e.g. acute otitis media)

  • Bone infections (e.g. osteomyelitis)
  • Gall bladder / Biliary tract infections
  • Helicobacter pylori infections (in combination with other drugs)
  • Lyme Disease
  • Dental abscess (as an adjunct to surgical management)
