Why has my vet prescribed Varenzin CA-1?
Chronic kidney disease is one of the most common long-term conditions affecting older cats. As kidney function declines, the kidneys produce less erythropoietin – the hormone responsible for stimulating red blood cell production. Over time this can lead to anaemia, reducing oxygen delivery around the body and contributing to lethargy, weakness and reduced quality of life.
Varenzin contains molidustat, which stimulates the body's natural response to low oxygen levels and encourages increased production of erythropoietin. This supports red blood cell formation and helps manage anaemia associated with chronic kidney disease under veterinary supervision.
Varenzin CA-1 is supplied as an oral liquid, allowing accurate dosing according to your veterinary surgeon's instructions.
What are the signs of anaemia in cats with kidney disease?
Cats affected by CKD-related anaemia may show signs including:
- Lethargy
- Weakness
- Sleeping more than usual
- Reduced appetite
- Weight loss
- Pale gums
- Reduced activity levels
- Poor exercise tolerance
Managing anaemia may help improve comfort, energy levels, appetite and overall wellbeing in affected cats.
How does Varenzin CA-1 work?
Varenzin contains molidustat, a hypoxia-inducible factor prolyl hydroxylase inhibitor (HIF-PHI). It works by activating the body's natural oxygen-sensing pathway, encouraging increased erythropoietin production and supporting red blood cell formation.
Treatment should always be initiated and monitored by a veterinary surgeon, with dosing adjusted according to haematology results and your cat's clinical response.
