Vasorex is a medication used to treat high blood pressure. It is a human medication that may be prescribed off-label by a veterinarian for pets. It contains the active ingredient Amlodipine and is often used in pets to treat high blood pressure (hypertension). In cats, high blood pressure is often associated with chronic kidney disease and thyroid disease. For dogs, causes may include overactive adrenal glands, chronic kidney disease, diabetes, and some types of tumours. While Vasorex (Amlodipine) can be used alone, it is generally combined with other medications.
Classified as a calcium-channel blocker, Amlodipine aids in lowering blood pressure by preventing calcium from entering the smooth muscles of the heart and blood vessels. This action causes the blood vessels to relax and widen, thus improving blood flow.
Give as directed by your veterinarian. Your veterinarian will determine the suitable dose and frequency for your pet.
Missed Dose:
If you miss a dose, give it when you remember, or if it's close to the time for the next dose, skip the missed one and continue with the regular schedule. Avoid giving extra or double doses.
Overdose:
Contact your veterinarian or the New Zealand National Poisons Centre at www.poisons.co.nz/animal-helpline/ or phone 0800 869 738.
Hypersensitivity: Pets with known hypersensitivity to amlodipine or other calcium channel blockers should not be given this medication.
Liver Disease: Pets with severe liver disease may require cautious use or adjustment in dosage.
Low Blood Pressure (Hypotension): Amlodipine can lower blood pressure, so it's contraindicated in pets with already low blood pressure.
Heart Failure: Caution is advised in pets with heart failure if caused by aortic stenosis, due to the potential for exacerbation of cardiac conditions.
Pregnant or Nursing Animals: The safety of amlodipine in pregnant or nursing animals has not been established.
Although it is generally well-tolerated, Vasorex may cause side effects. Common side effects include lethargy, increased heart rate, weight loss, vomiting and decreased appetite. Swelling of the gums may also occur, especially in cats. In rare cases, pets might experience a drop in blood pressure, leading to weakness or collapse. If side effects occur contact your vet.
Amlodipine should be stored at a controlled room temperature below 25°C. Keep it in a tightly closed container to protect it from moisture and light. Keep out of reach of children and pets.
