How DBL™ Gentamicin Injection BP is given
How much is given
Your doctor will decide what dose you will receive. This depends on your condition and other factors, such as your weight and kidney function.
How it is given
Gentamicin is given as an injection into a muscle or as a slow injection into a vein (intravenously). This medicine should only be given by a doctor, nurse or other trained person.
If you take too much (overdose)
As DBL™ Gentamicin Injection BP is usually given to you in hospital under the supervision of your doctor, it is very unlikely that you will receive an overdose.
Immediately telephone your doctor or the Poisons Information Centre (telephone 13 11 26) for advice, or go to Accident and Emergency at the nearest hospital, if you think that you or anyone else may have taken too much DBL ™ Gentamicin Injection BP.
