Valsartan is an FDA-approved commercial product, dispensed by Mixlab for veterinary use in dogs and cats. Available by prescription.
The uses and pharmacology described below reflect the FDA-approved labeling for this active ingredient; your veterinarian determines whether and how they apply to your animal's treatment plan.
Valsartan is an angiotensin II receptor blocker (ARB) that relaxes blood vessels and reduces the workload on the heart and kidneys. On the FDA-approved human label, it is indicated for hypertension and certain heart failure and kidney-related conditions.
In veterinary medicine, ARBs are used off-label in dogs and cats, most often as part of managing proteinuric kidney disease or hypertension; telmisartan is the most studied ARB in veterinary medicine, and valsartan is used by some clinicians as an alternative within the same drug class. This information is not a substitute for veterinary diagnosis, prescribing, or monitoring.
Your veterinarian will likely recommend periodic blood pressure checks and bloodwork, including kidney values, while your pet is on this medication. Commonly reported effects include decreased appetite and lethargy; low blood pressure can also occur, particularly when starting treatment or combining with other blood pressure medications. Tell your veterinarian about all other medications your pet is taking.
