1. What Heracillin is and what it is used for
The active substance in Heracillin, flucloxacillin, is penicillin (antibacterial drug), which prevents the bacterium from building a normal cell wall. Without a functioning cell wall, the bacterium dies quickly. Heracillin differs from regular penicillin in that it is stable against an enzyme ( beta-lactamase ), which has the ability to break down regular penicillin.
Heracillin is used in infections of the skin and soft tissues and infections of the joints, bones, and lungs.
Flucloxacillin contained in Heracillin may also be approved for the treatment of other conditions not mentioned in this product information. Ask your doctor, pharmacist, or other healthcare professional if you have any further questions, and always follow their instructions.
