What is Fortekor?

Fortekor tablets contain the active ingredient known as Benazepril which is an angiotensin-converting enzyme (ACE) inhibitor. This medication is commonly used to manage health conditions such as heart failure in dogs and chronic renal insufficiency in cats. It's often used alongside other medications, particularly for congestive heart failure, which may be caused by conditions like degenerative mitral valve disease and dilated cardiomyopathy in dogs. Fortekor is also beneficial for pets with kidney disease or proteinuria, a condition where proteins are abnormally present in the urine.

How does it work?

The active ingredient Benazepril functions by decreasing blood pressure and widening blood vessels, thus reducing the workload on the heart. It achieves this by blocking ACE, a protein that narrows blood vessels. This relaxation of blood vessels leads to decreased blood pressure. In pets with kidney disease, it helps in reducing protein leakage into the urine by relaxing the kidney's blood vessels.

Dose and Administration

It is important to follow the veterinarian’s directions regarding dosage and administration. Typically the usual dosage is once a day, with or without food whilst avoiding high-sodium treats. It is important to ensure your pet has constant access to water while on this medication.

Missed dose:

If a dose is missed please consult your veterinarian for guidance. They might advise you to give the missed dose when you remember, but if it is near to the next dose, skip the missed dose, and give the next dose as scheduled. Avoid double dosing.

Overdose:

Symptoms of overdose can include weakness, vomiting, high heart rate, collapse or lethargy. If any of these symptoms are present it is essential to contact your veterinarian or the New Zealand National Poisons Centre (0800 869 738, www.poisons.co.nz/animal-helpline/) in case of suspected overdose.
