Amlodipine besylate is used in cats for the treatment of systemic hypertension (high blood pressure). Although Amlodipine besylate is not FDA-approved for use in veterinary medicine, it is a commonly accepted practice for veterinarians to prescribe this medication for cats.
How it works: Amlodipine is known as a calcium-channel blocker. It works by blocking the calcium needed for muscle contraction. Amlodipine works primarily on the arterial muscles to relax them so they can dilate and the blood pressure decreases.
Cautions: Notify your doctor if your cat has liver problems before administering this medication. Amlodipine should not be used in pregnant or lactating animals. In rare instances, Amlodipine is used in dogs. If used in a dog, this medication may also cause the blood to take longer to clot.
Dosage & Administration: Give this medication exactly as directed by your veterinarian. If you do not understand the directions ask the pharmacist or veterinarian to explain them to you. Amlodipine besylate can be given with food. Do not stop giving amlodipine besylate. A missed dose can result in a sudden rise in blood pressure which can lead to blindness, kidney damage, seizures, or collapse. Store amlodipine besylate at room temperature away from moisture and heat. Keep this medication away from children and pets.
Possible side effects of Amlodipine: For dogs and cats, if any of the following serious side effects occur, stop giving amlodipine besylate and seek emergency veterinary medical attention; an allergic reaction (difficulty breathing; swelling of the lips; tongue or face; hives). In cats side effects are rare but may include drowsiness, loss of appetite, weight loss, swelling of the gums, or rapid heart rate. In dogs, may also cause the blood to take longer to clot. Other side effects may also occur. Talk to your veterinarian about any side effect that seems unusual or bothersome to the animal.
If you miss giving a dose: Give the missed dose as soon as you remember during the same day. However, if you don¿t remember until the next day, skip the dose you missed and give only the next regularly scheduled dose. Do not give a double dose of the medication.
If you overdose the pet: Seek emergency veterinary medical treatment. Symptoms of amlodipine besylate overdose include staggering due to dizziness, collapse, or slow heart rate.

Drugs other than those listed may also interact with amlodipine besylate. Talk to your veterinarian or pharmacist before giving any prescription or over the counter medicines including vitamins, and supplements.
