This medicine is an antibiotic used to treat serious bacterial infections, such as skin or blood infections, in adults and children over 1 year old.
The dose depends on your weight and the type of infection. It's usually 4 mg per kg for skin infections or 6 mg per kg for heart or blood infections.
A doctor or nurse will give it directly into a vein (intravenously). For adults, it's given as an infusion over 30 minutes or an injection over 2 minutes. For children (1-17 years), it's given as an infusion over 30-60 minutes.
This medicine is usually given once a day. If you have kidney problems, the dose might be given less often.
