Beta-blocker

A representation of Beta-blocker

Beta-blockers are drugs that lower blood pressure and relieve the heart. They are often used for people with cardiovascular disease, but they can also be helpful for dogs. In this article, you will find out when and how beta blockers are used in dogs, what side effects they have and what you need to watch out for.

When are beta-blockers used in dogs?

Beta-blockers work by reducing the effect of adrenaline and other stress hormones on the heart. This causes the heart to beat more slowly and less forcefully, which lowers blood pressure and improves the oxygen supply to the heart muscle. Beta-blockers can be used in dogs with various heart problems, for example

  • Cardiac arrhythmias: Beta-blockers can stabilize the heart and prevent dangerous extra beats.
  • Heart muscle thickening : Beta-blockers can slow down the growth of the heart muscle and improve the filling of the heart.
  • Heart valve defects: Beta-blockers can reduce the strain on the heart and alleviate the symptoms of heart failure.

How are beta-blockers used in dogs?

Beta-blockers are usually administered as tablets or capsules, which the dog must take regularly. The dosage depends on the severity of the condition, the weight of the dog and the type of beta-blocker. The vet will determine the optimal dose for your dog and adjust it if necessary. It is important that you follow the vet's instructions exactly and do not stop or change the medication on your own. This could lead to serious complications.

What side effects do beta-blockers have in dogs?

Beta-blockers are generally well tolerated, but can also have side effects. The most common are:

  • Fatigue: as the heart beats more slowly, the dog may be less active and less able to perform.
  • Low blood pressure : This can lead to dizziness, weakness or fainting.
  • Low blood sugar: This can lead to tremors, cravings or seizures.
  • Breathing difficulties: In dogs with asthma or chronic bronchitis, beta-blockers can constrict the bronchial tubes and make breathing difficult.

If you notice these or other unusual symptoms in your dog, you should contact your vet immediately. They can adjust the dose or prescribe a different medication.

What should you watch out for?

Beta-blockers are effective medications that can help your dog to keep his heart healthy. However, there are a few things you need to bear in mind for them to work optimally:

  • Tell the vet about any other medications or supplements your dog is taking. Some may not be compatible with beta-blockers or may increase or decrease their effect.
  • Monitor your dog's pulse and blood pressure regularly. The vet can show you how to do this. This will allow you to determine whether the medication is dosed correctly and how your dog is reacting to it.
  • Stick to a fixed feeding schedule. This will help to keep your dog's blood sugar stable and prevent food cravings.
  • Provide your dog with sufficient exercise. This promotes blood circulation and strengthens the cardiovascular system. However, make sure that you don't overdo it and give your dog enough rest breaks.

With these tips, you can give your dog a long and happy life with a healthy heart. If you still have questions about beta-blockers in dogs, you can contact your vet at any time. They will be happy to help you.
