What Gentamicin Injection is used for

Gentamicin Injection belongs to a group of medicines known as aminoglycoside antibiotics. Aminoglycoside

antibiotics work by preventing bacteria from growing and by killing them.

Gentamicin Injection is used to treat serious bacterial infections in many different parts of the body such as chest infections, urinary tract infections and infected wounds or burns.

Gentamicin Injection may be prescribed for other reasons that are not mentioned above. Your doctor will be able to tell you about the specific condition for which you have been prescribed it.

This medicine is available only with a doctor's prescription.

How it is given

Gentamicin Injection must only be given by a doctor or nurse. Gentamicin Injection is given by injection into the muscle or as a slow injection (infusion) into a vein.
