3. How Furosemide Injection is given
Your doctor or nurse will inject Furosemide Injection into a
muscle (intramuscularly) or into a vein (intravenously).
Furosemide will always be injected slowly.
Your doctor or nurse will decide on the correct dose for you but
usual initial doses are 20 - 50mg by intramuscular or slow
intravenous injection. If larger doses are required the injection
will be given to you as a slow infusion (drip). An infusion rate of
4mg per minute should not be exceeded. Your doctor or nurse
will adjust the dose according to its effects
For the treatment of difficulty in passing urine:
250mg may be given over the first hour. If the desired response
is not achieved within the next hour a further 500mg may be
given over the next 2 hours. If the desired response is still not
achieved within the next hour a further 1g may be given over the
next four hours. If a satisfactory response is still not achieved
your doctor may treat you using kidney dialysis. An effective dose
up to 1g may be repeated every 24 hours.
The elderly
The recommended dose is the same as for adults. Your doctor or
nurse may adjust your dose until the required effect is achieved
as this drug leaves the body more slowly in the elderly.
Usual dosage ranges from 0.5 - 1.5mg/kg body weight daily up to
