    What is Amlodipine?
    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. Amlodipine requires a prescription from your veterinarian, and is sold per tablet.
    For: Cats
    Treats high blood pressure in cats
    Relaxes the arterial muscles to help decrease blood pressure

    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.

    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.

Talk to your veterinarian or pharmacist before giving any prescription or over the counter medicines including vitamins, and supplements..

    Call your veterinarian for medical advice about any side effects to your pet. You may report side effects to the FDA at 1-800-FDA-1088.


    Give Amlodipine to your cat exactly as your veterinarian prescribes.

    Reduced calico cat's blood pressure My cat, Lexi, has hyperthyroidism for a few years. The meds manage her thyroid and keeps her weight up, but was not controlling her blood pressure. We have her checked every 6 months or so. One morning she had a bloody nose. We were distressed of course and took her to the vet. Her blood pressure was high. She was prescribed Amlodipine 2.5mg which I was getting from the local pharmacy. I was giving her 1/4 pill/day so the 7 pills I was getting each month was for approx. a month, 28 days. But, the price was $10.00 each time I filled the prescription. Was happy to be able to get Amlodipine here because the cost is so much better for a drug that is prolonging my 14 year old cat's life. 08/04/2014
    Works for us! My 16 year old cat suddenly went blind, so I rushed her to the animal hospital. The vet said that her blood pressure was through the roof (220-250). We started with 1/4 tablet, but that wasn't doing the trick. So we upped it to 1 tablet. She was doing better, but not great, so we upped it to 2 tablets. She can now see, and has gained a bit of weight back since she is less timid and scared. Her blood pressure is about 180, which is still high. We are now up to 2 and a 1/4 tablets, so I'm hoping it's helping her even more. The pills are small and she tolerates my throwing them down her throat on a daily basis... 02/16/2014
    My 20 year old cat has been on a low dose (6.25) of amlodipine for about 10days ...and she now hisses whenever I pick her up, put her down, pet her, etc. Is it possible this is a reaction to the drug? 11/04/2013
    Reversed Blindness!! My 16 year old cat went blind. The vet said there was nothing that could be done. She said that the blindness was probably caused by a brain thing. My husband looked up on internet,"Sudden Blindness in Cats". An article said that blindness could be brought on by high blood pressure (causing detached retinas). My vet hadn't even checked my cat's blood pressure. We brought our cat back to the vet. My cat's blood pressure was borderline high. The vet prescribed amlodipine (1/4 pill, 2.5 mg) along with enalapril (2.5 mg). Both pills once a day. After two days, my cat can see!! It is like a miracle!! 10/15/2012
    Helped my kitty so much!! In three short weeks, 1/2 a pill per day brought my cat's blood pressure down from over 200 to below 150. My cat seems very happy, and so am I. Putting it in a treat seems to work best for us, much better than the pill popper thing. I am glad her vet recommended this medicine for her. :) 01/29/2011

    Try a pill cutter and carefully cut into halves. Then take each half and cut that into halves.
    This is easier and more accurate than cutting with a knife or snapping with your fingers. Good Luck.

    The smallest size tablets available for amlodipine is 2.5mg, otherwise you may have to see if you can get it compounded into the appropriate dose for your cat.

    How hard is the pill

    I have had trouble cutting these pills in quarters. If this is made by a different supplier perhaps it will be easier to cut in fourths.

    Pill cutter shattered THIS PILL. Even bits would not dissolve in water or oil. Pharmacy "compounded" it for me in liquid; will try now. It has sugar so if pet is diabetic, can't use this.
    Thyroid med for cat divided and dissolved well in water...???

    Most of these small tablets are difficult to cut, you can try using a pill cutter (available at most drugstores) which should be much easier.
