Owhat FUROSEMIDE is and what IT IS USED FOR
• Furosemide 500 mg is a diuretic ("water tablet") used to remove excess water from the body by increasing the amount of urine produced
• Furosemide is used to treat oliguria, a condition in which there is reduced urine production.
2) BEFORE YOU TAKE FUROSEMIDE
DO NOT take Furosemide and tell your doctor if you:
• are allergic (hypersensitive) to any of the ingredients in your medicine
• are allergic (hypersensitive) to sulphonamides (used to treat infections) e.g. co-trimoxazole
• have severe liver disease
• have difficulty passing urine
• have kidney failure
• have severe hypovolaemia (an abnormally low volume of blood in the circulation)
• are dehydrated (you may have an increased thirst, dry lips and tongue, and pass smaller amounts of urine than usual)
• have been told that you have severe hyponatraemia (an abnormally low level of sodium in the blood)
• have been told that you have hypokalaemia (low levels of potassium in the blood)
• have been told that you have an electrolyte deficiency (low salt levels in the blood)
• are breast-feeding (see section on Pregnancy and breast-feeding)
• have normal or mildly to moderately reduced kidney function with a GFR greater than 20 ml/min, because of the risk of severe fluid and salt (electrolyte) loss.
This medicine is not recommended to the patients who
are in pre-coma or coma state associated with liver
disease.
Take special care with Furosemide
Tell your doctor before you start to take this medicine if
you:
• have a history of gout (causes excessive uric acid in the blood and painful inflammation of the joints mainly in the feet, hands and big toe)
• have diabetes
• have prostatic hypertrophy (enlargement of the prostate gland or narrowing of the ureter, the tube that connects the kidney and bladder)
• suffer with low blood pressure which can cause dizziness on standing, your fluid electrolyte balance should be regularly monitored and the dose should be adjusted accordingly. If you have circulation problems in the brain (cerebrovascular circulatory disorders) or heart vessels (coronary heart disease): the risks associated with a possible fall in blood pressure are higher
• have cirrhosis of the liver (tiredness, weakness, water retention, feeling or being sick, loss of weight or appetite, yellowing skin or eyes, itch) as well as reduced kidney function
• have been told that you have hyponatraemia (low concentration of sodium in the blood)
• have hypoproteinaemia which is an abnormally low level of protein in your blood
• are elderly.
Your doctor may need to do some blood tests from time to time to check the levels of sodium, potassium, creatinine and glucose in your blood. Close monitoring is necessary if you lose a lot of fluids (e.g. if you experience significant vomiting, diarrhoea or intensive sweating): any blood or fluid loss (hypovolaemia or dehydration) or any electrolyte or acid-base imbalance in your body will need to be corrected, which may require your doctor to temporarily stop your treatment with Furosemide. If you are to undergo a blood test remember to tell the doctor you are taking Furosemide. You should not lose more than 1 kg a day in body weight owing to the increase in urine production caused by Furosemide, regardless of how much urine you pass.
Your doctor may need to check the effect of your treatment with Furosemide periodically by temporarily stopping it.
If you are taking Furosemide for a long time, your doctor may recommend you to have a potassium rich diet (i.e. potatoes, bananas, tomatoes, spinach and dry fruits) or may also recommend a medical substitution of potassium.
If you see another doctor or go into hospital, let them or the staff know what medicines you are taking. Furosemide may increase the effects of muscle relaxants used in operations.
children
If the patient is a premature infant their kidney function will be monitored.
Furosemide may cause calcium deposits or stones in the kidneys of premature babies and increases the risk of a foetal blood vessel called the ductus arteriosus remaining open after birth when it should normally close, in premature babies with breathing difficulties. The doctor will therefore need to monitor the baby very closely.
Taking other medicines
Talk to your doctor if you are taking any of the
following:
• medicines used to treat high blood pressure (e.g. methyldopa), including other diuretics e.g. bendroflumethazide, as your blood pressure may become too low
• risperidone (used to treat mental illness)
• medicines used to treat abnormal heart rhythm (e.g. amiodarone)
• antibiotics (e.g. cefaloridine, kanamycin, gentamicin, tobramycin, cephalosporins, polymyxins), as there is an increased risk of kidney problems
• antibiotics known as an aminoglycoside, e.g. streptomycin or gentamicin
• non-steroidal anti-inflammatory drugs (e.g. aspirin, indometacin), as the effectiveness of Furosemide may be altered
• lithium, a treatment for depression, as lithium levels in the blood may be increased
• medicines used for diabetes (such as insulin or oral tablets), as the risk of "hypos" may be increased
• products that increase blood pressure (pressor amines e.g. adrenaline, noradrenaline)
• theophylline (used to help your breathing) or salicylates (e.g. aspirin), as their effectiveness may be increased
• cardiac glycosides (used for heart problems), e.g. digoxin, digitoxin, ACE inhibitors (used to treat heart and circulation problems), e.g. captopril or enalapril, sympathomimetics (used to treat asthma problems), e.g. salbutamol, or any medicines to treat low blood pressure, Angiotensin II receptor blocker e.g. losartan (used to treat high blood pressure)
• phenytoin or carbamazepine (used to treat epilepsy), aminoglutethimide (used to treat cancer), carbenoxolone (used to treat inflammation and ulceration), amphotericin (used to treat infections), reboxetine (used to treat depression), methotrexate (used to treat leukaemia) or you are being given cisplatin (used to treat cancer)
• corticosteroids (used to reduce inflammation and allergy), e.g. prednisolone, betamethasone, drugs that may affect your kidney function, e.g. probenecid, or any liquorice containing products
• laxatives used over a long period of time
• sucralfate (used to treat ulcers and inflammation of the stomach lining). Sucralfate and Furosemide must not be taken within 2 hours of one another as sucralfate may decrease the effectiveness of Furosemide
• curariform muscle relaxants (e.g. vecuronium).
Please tell your doctor or pharmacist if you are taking or have recently taken any other medicines, including medicines obtained without a prescription.
Pregnancy and breast-feeding
• If you are pregnant, planning to become pregnant or are breast-feeding, ask your doctor for advice before taking this medicine. Furosemide should only be used in pregnancy if indicated by your doctor or physician. Furosemide passes into breast milk; therefore you must stop breast-feeding if you are taking Furosemide.
Driving and using machines
• Furosemide may reduce your mental alertness. If you are affected, do not drive or operate machinery. Furosemide may impair your ability to react to such a degree that it may influence your capacity to drive and use machines. This is especially true at the beginning of treatment, when the dose is increased or the medicine switched, and if you consume alcohol during treatment.
Important information about some of the ingredients of Furosemide
• Patients who are intolerant to lactose should note that Furosemide tablets contain a small amount of lactose. If your doctor has told you that you have an intolerance to some sugars, contact your doctor before taking this medicine
• Furosemide 500 mg Tablets contain sunset yellow (EllO) which may cause allergic reactions.

howtotake furosemide
Always take Furosemide exactly as your doctor has told you. You should check with your doctor or pharmacist if you are not sure.
The tablets should be swallowed with a drink of water.
Sucralfate and Furosemide must not be taken within two hours of each other.
The usual dose is:
• Adults
Initially half a tablet a day. This may be increased to 3 or 4 tablets a day if necessary
• Children
Furosemide is not recommended for children
• Elderly
Your doctor will gradually adjust your dosage to suit your needs.
If you take more Furosemide than you should
If you (or someone else) swallow a lot of the tablets all together, or if you think a child has accidentally swallowed any of the tablets, contact your nearest hospital casualty department or your doctor immediately.
An overdose is likely to cause excessive urine production which could lead to dehydration and low salt levels in the blood. This in turn causes increased thirst, increased heartbeat and breathing, low blood pressure, blood clots, kidney problems, delirious states, feeling sick, sweating, loss of consciousness, appearance of a blue or purple coloration of the skin and confusion. The skin may look dry and lose its elasticity.
Please take this leaflet, any remaining tablets and the container with you to the hospital or doctor so that they know which tablets were consumed.
If you forget to take Furosemide
If you forget to take a tablet, take one as soon as you remember, unless it is nearly time to take the next one. Do not take a double dose to make up for a forgotten dose.
If you have any further questions on the use of this product, ask your doctor or pharmacist.
^4) possible side effects
Like all medicines, Furosemide can cause side effects, although not everybody gets them.
