Hydralazine Tablets, 10mg

Hydralazine Tablets for Canine and Feline Blood Pressure

Product Description

Hydralazine 10 mg Tablets are a prescription-only arteriolar vasodilator used off-label in dogs and cats to manage systemic hypertension and congestive heart failure. Blocking calcium entry into arterial smooth muscle cells forces vessel walls to relax and open up, cutting vascular resistance and bringing blood pressure down while taking some of the load off the heart with each beat.

Benefits

• Dilates Arterial Walls: Prevents calcium from reaching arterial smooth muscle cells, widening vessels and improving blood flow in dogs and cats.
• Reduces Cardiac Workload: Lowers vascular resistance so the heart works less hard with every beat in dogs and cats receiving treatment.
• Pulmonary Edema Support: Brought in during emergency situations for life-threatening pulmonary edema in dogs with advanced or decompensated heart failure.
• Combination Therapy Option: Can be paired with diuretics, ACE inhibitors, or pimobendan to deliver broader cardiovascular support for pets on treatment.
• Flexible Strength Option: A lower-dose choice for smaller pets or those where careful initial dose titration is needed under veterinary guidance.

Additional Information

Precautions

• Hypovolemia Caution: Avoid in pets with low blood volume, as further pressure reduction in these animals risks triggering dangerous cardiovascular collapse.
• Hypotension Contraindication: Pets that already have low blood pressure must not receive this product, as it will push levels down to a point that becomes life-threatening.
• Autoimmune Disease Risk: Pets with autoimmune conditions should be treated with care, as this product has been known to set off lupus-like reactions in some animals.
• Coronary Artery Disease: This product must not be given to pets with coronary artery disease or mitral valvular rheumatic heart disease under any circumstances.
• Kidney and Liver Disease: Pets with kidney or liver problems may hold onto this product longer, which can make its effects stronger and last longer than expected.
• Pregnancy Caution: Whether this product is safe during pregnancy or nursing has not been confirmed; only go ahead if the benefit to the animal clearly tips the scale.
• Intracerebral Bleeding: Pets with intracranial bleeding need very careful handling, as changes in blood pressure from this product could make the situation worse.
• Drug Interactions: Keep your vet informed of all medications, as anaesthetics, diuretics, and antihypertensives all interact with this product in pets.
• Baseline Testing Required: Chest X-rays taken before starting treatment give a useful reference point for tracking any cardiac changes during therapy.
• Prescription Only: Not FDA-approved for veterinary use; a licensed veterinarian must directly order this product before it can be dispensed.

Possible Side Effects

• Severe Hypotension: The biggest risk is dangerously low blood pressure, which tends to develop when doses are raised too quickly.
• Reflex Tachycardia: Some pets respond to the blood pressure drop from this product by developing a noticeably elevated heart rate.
• Vomiting and Diarrhea: Vomiting and loose stools rank among the most frequently reported reactions in pets receiving this product during treatment.
• Reduced Appetite: A common reaction in treated pets; watch food intake carefully and report any noticeable drop to your veterinarian.
• Fluid Accumulation: Fluid and sodium may pool in the body, causing swelling or making existing accumulation worse in cardiac patients.
• Eye Inflammation: Conjunctivitis has been noted in some treated pets; flag this to your veterinarian as soon as it appears.

Storage Information

• Room Temperature Storage: These tablets hold up best in a sealed container between 68°F and 77°F, away from heat and light.
• Away from Sunlight: Direct sunlight degrades tablet quality over time; always store this product well away from any direct light source.
• Keep Out of Reach: Store in a secure spot that children and other household animals cannot access to prevent any accidental ingestion.

Frequently Asked Questions

Q1: What is Hydralazine 10 mg used for in dogs and cats?

Ans: Used off-label in dogs and cats to treat systemic hypertension and congestive heart failure, this product blocks calcium in arterial smooth muscle to widen vessels and lower pressure. It is generally reached for when first-line cardiac medications are no longer adequate.

Q2: How is Hydralazine 10 mg different from the 25 mg tablet?

Ans: Both carry the same active ingredient and work identically. The 10 mg tablet is the lighter option, suited to smaller pets or cases needing more careful dose titration at the start. The right strength must always be determined by a licensed veterinarian.

Q3: Why is monitoring so important while my pet takes Hydralazine?

Ans: The gap between a helpful and a harmful dose is narrow with this product. Blood pressure, gum colour, blood electrolytes, and cell counts are all monitored throughout treatment. Chest X-rays taken before starting give a useful baseline to compare against as therapy progresses.

Q4: Can Hydralazine cause my pet's heart rate to increase?

Ans: Yes. Reflex tachycardia is a known response to blood pressure falling from this product. The body speeds the heart up to compensate, and your vet may add a beta-blocker to the treatment plan to keep heart rate stable throughout.

Q5: What signs should prompt me to call the vet while my pet is on Hydralazine?

Ans: Call your vet if weakness, fainting, persistent vomiting, poor appetite, or eye inflammation develops. These may indicate the dose is too high or a reaction is occurring. Go to an emergency clinic straight away if your pet collapses.
