These signs are episodic.
Other effects consistent with the pharmacological activity of torasemide were
observed in pre-clinical studies in healthy dogs at the recommended dose, i.e. dry
mucosa of the oral cavity, reversible increases in glucose and aldosterone serum
concentrations, decrease in urine specific gravity and increase in urine pH.
Reporting adverse events is important. It allows continuous safety monitoring of a
veterinary medicinal product. Reports should be sent, preferably via a veterinarian,
to either the marketing authorisation holder or its local representative or the national
competent authority via the national reporting system. See the package leaflet for
respective contact details.

Special precautions for use in animals
In dogs presenting with acute pulmonary oedema requiring emergency treatment,
the use of injectable medicinal products should be considered first before
commencing oral diuretic therapy.
Renal function (measurement of blood urea and creatinine as well as urine protein:
creatinine (UPC) ratio), hydration status and serum electrolytes status should be
monitored prior to and during treatment at very regular intervals according to the
benefit-risk assessment performed by the responsible veterinarian (see sections 4.5
and 4.9 of the SPC). The diuretic response to torasemide may increase over time
upon repeated dosing, particularly at doses greater than 0.2 mg/kg/day; therefore
more frequent monitoring should be considered.
Torasemide should be used with caution in cases of diabetes mellitus. Monitoring of
glycaemia in diabetic animals is recommended prior to and during treatment. In dogs
with pre-existing electrolyte and/or water imbalance, this should be corrected prior to
treatment with torasemide.
As torasemide increases thirst, dogs should have free access to fresh water.
In case of loss of appetite and/or vomiting and/or lethargy or in case of treatment
adjustment, renal function (blood urea and creatinine as well as urine
protein:creatinine (UPC) ratio) should be assessed.
In a clinical field trial, the efficacy of Isemid was demonstrated when it was used as a
first line treatment. Transferring treatment from an alternative loop diuretic to this
veterinary medicinal product has not been evaluated and such a change should only
be implemented based on a benefit-risk assessment performed by the responsible
veterinarian.
The safety and efficacy of the product has not been assessed for dogs weighing less
than 2.5 kg. For these animals use only according to the benefit/risk assessment by
the responsible veterinarian.
The tablets are flavoured.
Special precautions to be taken by the person administering the veterinary medicinal
product to animals
This veterinary medicinal product may cause increased urination, thirst and/or
gastrointestinal disturbances and/or hypotension and/or dehydration if ingested. Any
part-used tablets should be returned to the blister pack and then to the original
carton to help prevent access by children. In case of accidental ingestion, particularly
by a child, seek medical advice immediately and show the package leaflet or the
label to the physician.
This veterinary medicinal product may cause hypersensitivity (allergic) reactions in
persons that are sensitized to torasemide. People with known hypersensitivity to
torasemide, to sulfonamides or to any of the excipients should avoid contact with the

veterinary medicinal product. If symptoms of allergy occur, seek medical advice and
show the product packaging to the physician.
Wash hands after use.

response.
Concomitant use with NSAIDs, aminoglycosides or cephalosporins may increase the
risk of nephrotoxicity and/or ototoxicity of those medicinal products.
Torasemide may antagonise the action of oral hypoglycaemic agents.
Torasemide may increase the risk of sulfonamide allergy.
In cases of co-administration with corticosteroids, the effects of loss of potassium
may be potentiated.
In cases of co-administration with amphotericin B, increased potential for
nephrotoxicity and intensification of electrolyte imbalance can be observed.
No pharmacokinetic interactions have been reported following co-administration of
torasemide with digoxin; however hypokalaemia can enhance digoxin-induced
arrhythmias.
Torasemide can reduce the renal excretion of salicylates, leading to an increased
risk of toxicity.
Care should be exercised when administering torasemide with other highly plasma
protein bound drugs. Since protein binding facilitates the renal secretion of
torasemide, a decrease in binding due to displacement by another drug may be a
cause of diuretic resistance.
Concomitant administration of torasemide with other substances metabolised by
cytochrome P450 families 3A4 (e.g.: enalapril, buprenorphine, doxycycline,
cyclosporine) and 2E1 (isoflurane, sevoflurane, theophylline) may decrease their
clearance from the systemic circulation.
The effect of antihypertensive veterinary medicinal products, especially angiotensin
converting enzyme (ACE)-inhibitors, may be potentiated when co-administered with
torasemide.
Remaining tablet parts should be stored in the blister and be given at the next
administration.
Keep the tablets out of the reach of animals in order to avoid any accidental
ingestion.
