For a full list of excipients, see section 6.1
Clear solution with a characteristic orange odor.
Furosemide is indicated in all conditions requiring prompt diuresis in patients
who are unable to take solid dose forms. Indications include cardiac,
pulmonary, hepatic and renal oedema, peripheral oedema due to mechanical
obstruction or venous insufficiency and hypertension.
Posology and method of administration
This liquid should only be taken orally.
The medication should be administered in the morning to avoid nocturnal
Adults (more than 18 years of age): The usual initial daily dose is 40mg. This
may be adjusted until an effective dose is achieved.
Elderly: in the elderly, Furosemide is generally eliminated more slowly.
Dosage should be titrated until the required response is achieved.
This product is not recommended to use in children below 18 years of age.
Hypovolaemia or dehydration. Anuria. Renal failure with anuria not
responding to furosemide, or as a result of poisoning by nephrotoxic or
hepatotoxic agents, or associated with hepatic coma. Severe hyperokalaemia,
hyperkalaemia and severe hyponatraemia. Pre-comatose and comatose states
associated with hepatic encephalopathy. Breast feeding.
Contra-indicated in hypersensitivity to Furosemide, sulphonamides or any of
the excipients listed.
Patients allergic to sulphonamides may show cross-sensitivity to furosemide.
Special warnings and precautions for use
This product should not be given to children because its ethanol content may
affect their CNS.
Caution is required in patients liable to electrolyte deficiency. Regular
monitoring of serum sodium, potassium and creatinine is generally
recommended during furosemide therapy; particularly close monitoring is
required in patients at high risk of developing electrolyte imbalances or in case
of significant additional fluid loss. Hypovolaemia or dehydration as well as
any significant electrolyte and acid-base disturbances must be corrected. This
may require temporary discontinuation of furosemide. Where indicated, steps
should be taken to correct hypotension or hypovolaemia before commencing
Urinary output must be secured. Patients with partial obstructions of urinary
outflow for example patients with prostatic hypertrophy or impairment of
micturition have an increased risk of developing acute urinary retention and
require careful monitoring.
Particularly careful monitoring is necessary in:
• Patients with hypotension
• Patients who are at risk from a pronounced fall in blood pressure
• Patients with gout
• Patients with hepatorenal syndrome
• Patients with hypoproteinaemia, e.g. associated with nephrotic syndrome (the
effect of furosemide may be weakened and its ototoxicity potentiated).
Cautious dose titration is required
Patients that might manifest latent diabetes
Diabetic patients who might show increased insulin requirements
• Premature infants (possible development nephrocalcinosus/nephrolithiasis;
renal function must be monitored and renal ultrasonography performed).
The use of some diuretics is considered to be unsafe in acute porphyria
therefore caution should be exercised.
This product contains:
Ethanol (alcohol) 11.7 vol %, i.e. up to 369.6mg per dose, equivalent to 9.4 ml
beer, 3.9 ml wine per dose. Harmful for those suffering from alcoholism. To
be taken into account in pregnant or breast-feeding women, children and highrisk groups such as patients with liver disease, epilepsy.
It may cause flatulence, abdominal distension or diarrhoea if given in large
quantities to adults who are unable to take solid oral dose forms of furosemide.
Patients with rare hereditary problems of fructose intolerance, should not take
Interaction with other medicinal products and other forms of interaction
ACE Inhibitors: Enhanced hypotensive effect when given with diuretics. A
marked fall in blood pressure and deterioration in renal function may be seen
when ACE inhibitors are added to furosemide therapy. The dose of furosemide
should be reduced for at least three days, or the drug stopped, before initiating
the ACE inhibitor or increasing the dose of an ACE inhibitor.
Alpha-blockers: Enhanced hypotensive effect when diuretics are given with
alpha-blockers, also increased risk of first dose hypotension with post-synaptic
alpha-blockers such as prazosin.
Analgesics: Diuretics can increase the risk of nephrotoxicity of NSAIDs, also
antagonism of diuretic effect. Antagonism of diuretic effect (especially with
indomethacin and ketorolac). Salicylic toxicity may be increased by
Angiotensin –II Receptor Antagonists: Enhanced hypotensive effect when
diuretics given with angiotensin-II receptor antagonists.
Anti-arrhythmics: Hypokalaemia caused by loop diuretics increases cardiac
toxicity with amiodarone, disopyramide, flecainide, and antagonises the action
of lidocaine and mexiletine.
Antibacterials: Avoid the use of diuretics in lymecycline treatment. There is
an increased risk of ototoxicity when loop diuretics are given with
aminoglycosides, polymyxins or vancomycin. Since this may lead to
irreversible damage, these drugs must only be used with furosemide if there
are compelling medical reasons. Impairment of renal function may develop in
patients receiving concurrent treatment with furosemide and high doses of
Antidepressants: Possible increase of hypokalaemia when loop diuretics are
given with reboxetine. There is an enhanced hypotensive effect when diuretics
are given with MAOIs. There is an increased risk of postural hypotension
when diuretics are given with tricyclic antidepressants.
Antiepileptics: There is an increased risk of hyponatraemia when diuretics are
given with carbemazepine. The effects of furosemide are antagonised by
Antifungals: There is an increased risk of hypokalaemia when loop diuretics
are given with amphotericin.
Antipsychotics: Hypokalaemia caused by diuretics increase the risk of
ventricular arrhythmias with amisulpiride or sertindole. An enhanced
hypotensive effect may be seen when diuretics are given with phenothiazines.
Hypokalaemia caused by diuretics increases risk of ventricular arrhythmias
with pimozide (avoid concomitant use).
Antivirals: Plasma concentration of diuretics may be increased by nelfinavir,
ritonavir or saquinavir.
Atomoxetine: Hypokalaemia caused by diuretics increases the risk of
ventricular arrhythmias with atomoxetine.
Barbiturates: Plasma concentrations of diuretics may be decreased. There may
be an increased risk of osteomalacia when diuretics are taken in combination
Beta-blockers: There is an enhanced hypotensive effect when diuretics are
given with beta-blockers. Hypokalaemia caused by loop diuretics increases the
risk of ventricular arrhythmias with sotalol.
Cardiac glycosides: Hypokalaemia caused by loop diuretics increases cardiac
toxicity with cardiac glycosides.
Ciclosporin: there is an increased risk of nephrotoxicity and possibly
hypermagnesaemia when diuretics are given with ciclosporin.
Cisplatin: There is a risk of increased ototoxic effects if cisplatin and
furosemide are given concomitantly. In addition, nephrotoxicity of cisplatin
may be enhanced if furosemide is not given in low doses (e.g. 40mg in
patients with normal renal function) and with positive fluid balance when used
to achieve forced diuresis during cisplatin treatment.
Corticosteroids: The diuretic effect of diuretics is antagonized by
corticosteroids. There is an increased risk of hypokalaemia when loop
diuretics are given with corticosteroids.
Other Diuretics: There is an increased risk of hypokalaemia when loop
diuretics are given with acetazolamide. Profound diuresis is possible when
metolazone is given with furosemide. There is an increased risk of
hypokalaemia when loop diuretics are given with thiazides and related
Lithium: Loop diuretics reduce the excretion of lithium, which may lead to
increased plasma concentrations and a risk of toxicity. Therefore, it is
recommended that lithium levels are carefully monitored and where necessary
the lithium dosage is adjusted in patients receiving this combination.
Potassium salts: There is an increased risk of hypokalaemia when given with
Sucralfate: Furosemide and sucralfate must not be taken within 2 hours of
each other as sucralfate decreases the absorption of furosemide from the
intestine and so reduces its effect.
Sympathomimetics, Beta 2: There is an increased risk of hypokalameia when
loop diuretics are given with high doses of beta2 synpathomimetics.
Tacrolimus: There is an increased risk of hypokalaemia when given with
Theophylline: There is an increased risk of hypokalaemia when loop diuretics
are given with theophylline.
Carbenoxolone, prolonged use of laxatives, liquorice: May increase the risk of
Warfarin and clofibrate: Warfarin and clofibrate compete with furosemide in
the binding to serum albumin. This may have clinical significance in patients
with low serum albumin levels (e.g. in nephrotic syndrome). Furosemide does
not change the pharmacokinetics of warfarin to a significant extent, but a
strong diuresis with associated dehydration may weaken the antithrombotic
effect of warfarin.
Probenecid, methotrexate and other drugs which, like furosemide, undergo
significant renal tubular secretion may reduce the effect of furosemide.
Conversely, furosemide may decrease renal elimination of these drugs. In
case of high-dose treatment (in particular, of both furosemide and the other
drugs), this may lead to increased serum levels and an increased risk of
adverse effects due to furosemide or the concomitant medication.
Pregnancy and lactation
Results of animal work, in general, show no hazardous effect of furosemide in
pregnancy. There is clinical evidence of safety of the drug in the third
trimester of human pregnancy; however, furosemide crosses the placental
barrier. It must not be given during pregnancy unless there are compelling
Furosemide passes into breast milk and may inhibit lactation. Breastfeeding
must be avoided during treatment with furosemide.
Effects on ability to drive and use machines
Mental alertness may be reduced and the ability to drive or operate machinery
may be impaired.

High-Ceiling Diuretic Sulfonamide - CO3C A 01
Furosemide is a potent loop diuretic which inhibits sodium and chloride
reabsorption at the Loop of Henlé. The drug eliminates both positive and
negative free water production. Furosemide acts at the luminal face of the
epithelial cells by inhibiting co-transport mechanisms for the entry of sodium
and chloride. Furosemide gains access to its site of action by being transported
through the secretory pathway for organic acids in the proximal tubule. It
reduces the renal excretion of uric acid. Furosemide causes an increased loss
of potassium in the urine and also increases the excretion of ammonia by the
Furosemide is a weak carboxylic acid which exists mainly in the dissociated
form in the gastro-intestinal tract. Furosemide is rapidly but incompletely
absorbed (60-70%) on oral administration and its effect is largely over within
four hours. The optimal absorption site is the upper duodenum at pH 5.0.
Regardless of route of administration, 69-97% of activity from a radio-labelled
dose is excreted in the first 4 hours after the drug is given. Furosemide is
mainly eliminated via the kidneys (80-90%); a small fraction of the dose
undergoes biliary elimination and 10-15% of the activity can be recovered
from the faeces.
When oral doses of Furosemide are given to normal subjects the mean
bioavailability of the drug is approximately 52% but the range is wide. In
plasma, Furosemide is extensively bound to proteins mainly to albumin. The
unbound fraction in plasma averages 2 - 4% at therapeutic concentrations. The
volume of distribution ranges between 170 - 270ml/Kg. The half life of the ß
phase ranges from 45 - 60 min. The total plasma clearance is about
200ml/min. Renal excretion of unchanged drug and elimination by metabolism
plus faecal excretion contribute almost equally to the total plasma clearance.
Furosemide is in part cleared by the kidneys in the form of the glucuronide
