Hydralazine Tablets, 25mg

Hydralazine Tablets for Hypertension and Heart Failure in Pets

Product Description

Hydralazine 25 mg Tablets are a prescription-only arteriolar vasodilator used off-label in dogs and cats for hypertension and congestive heart failure. Relaxing the smooth muscle walls of arterioles widens blood vessels, lowers pressure, and eases the workload on the heart. Not FDA-approved for veterinary use, it is widely and legally prescribed off-label by licensed veterinarians.

Benefits

• Reduces Blood Pressure: Relaxes arterial smooth muscle to widen blood vessels, bringing systemic blood pressure down effectively in dogs and cats.
• Supports Heart Failure: Reduces cardiac afterload in dogs with congestive heart failure, easing the strain on the heart with every beat.
• Refractory CHF Management: Used when standard ACE inhibitors and pimobendan no longer give adequate control in dogs with advanced heart failure.
• Mitral Valve Support: A useful option for dogs with heart failure tied to degenerative mitral valve disease causing high arterial resistance.
• Hypertensive Crisis Use: Addresses acute and chronic systemic hypertension in dogs and cats, including urgent hypertensive crisis situations under veterinary care.

• Drug Interactions: ACE inhibitors, beta-blockers, calcium channel blockers, diuretics, and anaesthetics may all interact significantly with this product in treated pets.

Frequently Asked Questions

Q1: What is Hydralazine 25 mg used for in dogs and cats?

Ans: Used off-label in dogs and cats to manage systemic hypertension and congestive heart failure, this product relaxes arterial walls to lower pressure and ease cardiac workload. It tends to be reached for when standard heart medications are no longer holding up well enough.

Q2: Is Hydralazine a first-line blood pressure medication for pets?

Ans: No, this is not a first-choice antihypertensive for pets. It is held back for hypertensive crises and advanced heart failure where ACE inhibitors and pimobendan have stopped working adequately. Your vet will decide if it is the right fit for your pet.

Q3: Why does Hydralazine need to be started at a low dose?

Ans: The gap between a helpful dose and a harmful one is narrow with this product. Starting low and moving up slowly lets vets keep a close eye on blood pressure and steer clear of sudden drops causing weakness or fainting.

Q4: What should I monitor at home while my pet takes Hydralazine?

Ans: Watch for weakness, low energy, or fainting pointing to low blood pressure, and vomiting or poor appetite as digestive signs. Report anything unusual to your vet straight away. Blood pressure checks and kidney function tests are typically part of the ongoing monitoring plan.

Q5: Does Hydralazine interact with other heart medications in pets?

Ans: Yes. ACE inhibitors, beta-blockers, calcium channel blockers, diuretics, corticosteroids, and anaesthetics all have the potential to interact with this product. Give your vet a full and current list of every medication, supplement, and herbal remedy your pet is on before treatment begins.
