Amlodipine Side Effects in Cats

Amlodipine side effects are not very common in cats, but they can still occur. The side effects may include depression, increased heart rate, weakness and fainting, weight loss and reduced kidney function. Amlodipine is a prescription medication used to control high blood pressure (hypertension). Left untreated, high blood pressure can affect the heart, eyes, kidneys and brain.

Amlodipine Side Effects in Cats

Amlodipine is an effective drug used in cats with high blood pressure and is considered safe in most cases. However, it can have a number of side effects in some cats. Watch out for side effects such as:

  • Low blood pressure (hypotension)
  • Loss of appetite and weight loss
  • Reduced kidney function
  • Increased heart rate
  • Depression
  • Weakness
  • Sudden fainting

Basically, all of the above mentioned side effects are the result of decreased blood pressure. The heart rate increases in order to supply blood in the body. If the cat is affected by low blood pressure, the tissues in the body are not properly oxygenated and nourished and this leads to weakness, depression and fainting. If the blood pressure in the kidneys is below the normal level, the transfer and elimination of toxins is more difficult.These symptoms might also manifest when the blood pressure is reduced to normal levels, but only if the blood pressure suddenly drops from a very elevated level.

It is recommended to notify your veterinarian as soon as you notice any side effects that you can link to the administration of the meds. Your veterinarian will decide the future course of treatment.Regular blood pressure measurements are recommended in cats suffering from high blood pressure that receive amlodipine.

Administration of Amlodipine in Cats

When treating your cat with amlodipine you should closely follow your veterinarian’s recommendations regarding the dosage and the period of administration. Complete the treatment even if the cat’s condition seems to be improved.

Amlodipine comes in tablets which could be cut in smaller pieces when administered to cats. It can be given along with the meals. If you forget to administer a dose, do not try to compensate by doubling it when you administer the following dose. If you suspect a medication overdose, you should contact your veterinarian. If another animal in your household takes the drug by mistake, visit the vet. Make sure you store the drug according to the manufacturer’s specifications.

Contraindications of Amlodipine

Amlodipine should be avoided in animals that are hypersensitive or allergic to the medicine. There are drugs which interfere with amlodipine such as diuretics or other medication administered to lower blood pressure. Let your veterinarian know if your cat has a history of liver problems. Amlodipine should be administered cautiously in these cases. Cats suffering from high blood pressure should not get medication that will increase blood pressure (i.e. asthma medicine or phenylpropanolamine). You should consult your veterinarian and let him know about all types of treatments you administer to your pet before he decides on the amlodipine treatment.

Amlodipine is not recommended in pregnant cats or felines that are during their lactation period.
