Do not use in case of hypersensitivity to the active substance or to any of the
excipients.
Do not use in cases of hypotension, hypovolaemia, hyponatraemia or acute renal
failure.
Do not use in cases of cardiac output failure due to aortic or pulmonary stenosis.
Do not use in pregnancy or lactation (see section 4.7).

In double-blind clinical trials in dogs with heart failure, the product was well tolerated
with an incidence of adverse reactions lower than observed in placebo-treated dogs.
A small number of dogs may exhibit transient vomiting, incoordination or signs of
fatigue.
In cats and dogs with chronic kidney disease, the product may increase plasma
creatinine concentrations at the start of therapy. A moderate increase in plasma
creatinine concentrations following administrations of ACE inhibitors is compatible with
the reduction in glomerular hypertension induced by these agents, and is therefore not
necessarily a reason to stop therapy in the absence of other signs.
The product may increase food consumption and body weight in cats.
Emesis, anorexia, dehydration, lethargy and diarrhoea have been reported on rare
occasions in cats.

Do not store above 25°C. Store in a dry place.
