1. WHAT FUROSEMIDE INJECTION IS AND WHAT IT IS USED FOR
Furosemide is one of a group of medicines called diuretics. A diuretic helps get rid of excess fluid in the
body by causing more urine to be passed.

of urine.

Pregnancy, breast-feeding and fertility
Pregnancy
-if you are pregnant or breast feeding, think you may be pregnant or are planning to have a baby, ask
your doctor or nurse for advice before taking this medicine. Furosemide passes through the placenta and
hence should not be given during pregnancy unless doctor feels it extremely necessary. If it is given in
cases of swelling or water retention, the growth of the baby must be regularly monitored.
Breast-feeding
-furosemide passes into the milk and may inhibit secretion of milk. Hence it should be avoided in breast
feeding women.

Furosemide may cause some patients to be less alert which could interfere with the ability to drive or
to operate machines. If you notice that you are not as alert as usual, do not drive or operate machinery
and ask your doctor for advice.

3. HOW FUROSEMIDE INJECTION IS GIVEN TO YOU
Furosemide Injection will always be given to you by a doctor or nurse. This is because it can only be
given by injection. It may be given by injecting the solution into a muscle (intramuscular) or by injecting
it slowly into a vein (intravenous).
Your doctor will decide on the most suitable dose for you, and how the medicine will be given. The
dosage and frequency of repeated doses may change depending on how you respond to treatment.
The recommended dose is;
Adults: The initial dose may vary from 20 mg to 250 mg depending on how you respond.
Elderly: Furosemide is generally cleared from the body more slowly in the elderly. If you are elderly,
your doctor may decide to start with a low dose and increase the dose gradually according to your
response.
Children: The doctor will decide on the dosage, depending on how severely the kidneys are affected
and on the response to initial doses.
Whilst you are receiving treatment with this medicine, your doctor may want to take blood for testing
which will show if you have the right balance of fluid and chemicals in the body.
If you have any further questions on the use of this product, ask your doctor or pharmacist.

furosemide can cause an excessive depletion of bodily fluids (e.g. passing urine more often than
normal) and minerals (sodium, potassium, magnesium, calcium). Symptoms that can occur are
thirst, headache, confusion, muscle cramps, increased irritability of the muscles, muscular
weakness, heart rhythm disturbances and gastrointestinal problems such as sensation of unease
and discomfort in stomach with an urge to vomit, or diarrhoea
