Amodip for cats



Active ingredient



Blood pressure

What is Amodip?

Amodip is a brand name for a drug with the active ingredient amlodipine. Amlodipine is a calcium channel blocker. It reduces high blood pressure (hypertension) in cats by widening blood vessels.

What does Amodip do?

Amodip, containing the active ingredient Amlodipine, is a medication commonly prescribed for cats with hypertension (high blood pressure). It is a calcium channel blocker. This means that it blocks calcium from entering the cells of the heart and blood vessels. This reduces the heart rate and relaxes the blood vessels, which lowers blood pressure. In this way, Amodip manages high blood pressure (hypertension) in cats.

Amodip works quickly in cats, with peak activity within a few hours.

What is Amodip for?

Amodip is used for the following conditions in cats:

High blood pressure (hypertension): Often used in cats with hypertension due to kidney disease, abnormally high thyroid levels (hyperthyroidism), etc.

Untreated hypertension can lead to serious complications, such as seizures, blindness and heart damage. That is why Amodip plays a crucial role in the management of hypertension by lowering blood pressure and reducing the risk of associated complications.

What are the possible side effects with Amodip?

While generally well-tolerated, Amodip (like any other medication) can have side effects. Side effects include:

Hypotension: Amodip may cause low blood pressure in some cats, leading to symptoms such as weakness, lethargy, or fainting. Monitor your cat closely for such signs, and inform your vet immediately if you notice them in your cat. Also, do attend scheduled follow-ups with your vet, so that they can adjust your cat’s dose if required.

Gut upset: Gut issues such as nausea, vomiting, or diarrhoea may occur as side effects of Amodip treatment in cats. These symptoms are usually mild and transient but should be monitored closely. Contact your vet if these symptoms worsen or become prolonged.

Swollen limbs (peripheral oedema): Although uncommon, some cats develop swollen limbs while on Amodip, due to fluid retention. Contact your vet immediately if you notice this in your cat

Swollen lymph nodes: Some cats may develop swollen lymph nodes (lymph nodes are part of the immune system). Contact your vet if you notice lumps in your pet.

Mildly inflamed gums: Mildly reddened, swollen gums may occur in some cats.

Decreased blood potassium levels (Hypokalaemia):  Signs include weakness, an inability to raise their head, constipation and excessive drinking/urination. Older cats with kidney disease should be monitored particularly closely, as kidney disease can cause hypokalaemia. Speak to your vet promptly if you notice these signs in your cat.

Allergic reactions: Allergic reactions to Amodip are uncommon but can occur in some cats. Signs of an allergic reaction may include itching, rash, swelling of the face or throat, difficulty breathing, or collapse. Seek veterinary attention immediately if you suspect an allergic reaction.

Remember, not all pets will experience these side effects, and the benefits of using Amodip often outweigh the risks, especially in pets with serious health conditions. However, if you notice any concerning symptoms or changes in your pet’s behaviour or health while they are taking Amodip, contact your veterinarian immediately. They can provide guidance and adjust the treatment plan if necessary to ensure your pet’s safety and well-being.

Which pets is Amodip not suitable for?

  • Cats with liver failure as amlodipine is broken down by the liver.

  • Cats with abnormally narrowed, thickened aortic valves (aortic stenosis).

 Amodip should be used with caution in the following cats:

  • Cats with liver disease

How to give Amodip safely

  1. Follow vet instructions: Always use Amodip exactly as your vet has prescribed. This includes the right dose and frequency. Never adjust the dose on your own, even if your dog or cat seems to be feeling better or worse. If you aren’t sure of the dose prescribed, please call your vet to confirm.
  2. Give with or after food: Amodip can be given to cats with or without food. However, do give Amodip according to your vet’s instructions.
  3. Check with your vet if giving anything else:  Amodip may increase the risk of side effects if given with other medications (e.g. ondansetron).

    Your vet should be aware of other drugs your pet is on, but it’s always worth double-checking in case there’s been a miscommunication somewhere.
    If your dog is on supplements or non-prescription treatments you should also tell your vet when they prescribe Amodip, as they may not be suitable to be given together.
  4. Storage and Handling: Store Amodip according to the instructions on the label, usually in a cool and dry place. Make sure it’s out of reach of children and other pets.
  5. Report any accidental overdose to your vet immediately: If you have mistakenly given too much Amodip, report it to your vet as soon as you realise the error. They may recommend blood tests, intravenous fluids, or monitoring, depending on the severity of the overdose.
