What is Beta-blockers Poisoning?

Beta-blockers are used for heart disease in the regulation of blood pressure in humans. They are also prescribed to dogs to regulate the heartbeat; however, it is prescribed carefully by veterinarians. When an overdose occurs by a dog, heart failure and kidney failure can ensue. Beta-blockers decrease the workload of the heart by altering the response to nerve impulses, and an overdose can very quickly lead to adverse effects.

Propranolol is a common beta-blocker that is successful in blocking the beta-1 and beta-2 receptors, known as norepinephrine and epinephrine. These receptors are responsible for the elevation of the heart rate during stressful situations. Beta-blockers decrease the heart rate, thus the amount of oxygen required for the cardiovascular system to work properly.

Propranolol can negatively interfere with other medications. It is important to only have this beta-blocker prescribed under a veterinarian’s care, as the veterinarian is aware of the other medications the dog is taking. Anesthetic agents, thyroid medications, hydralazine, cimetidine, insulin, lidocaine, and antacids are some of the medications that can interfere with propranolol.

Beta-blockers poisoning in dogs is a result of dogs ingesting human beta-blocker medication, such as propranolol, or overdosing on a beta-blocker medication that has been prescribed to them.

Symptoms of Beta-blockers Poisoning in Dogs

Beta-blockers can poison a dog very rapidly and it only takes a small amount to do so. Symptoms of beta-blocker poisoning in dogs include:

  • Vomiting
  • Nausea
  • Decreased heart rate
  • Lethargy
  • Weakness
  • Slow breathing
  • Slow heart rate
  • Seizures
  • Collapse


Propranolol can also be referred to a beta-blocker with another name. If your dog has ingested a beta-blocker medication prescribed to you, it is important to know the other names of these types of medications. Alternate names include:

  • Heart medication
  • Esmolol
  • Nadolol
  • Sotalol
  • Metoprolol
  • Timolol
  • Carvedilol
  • Atenolol
  • Generic cardiac medication
  • Generic blood pressure medication

Causes of Beta-blockers Poisoning in Dogs

Causes of beta-blocker poisoning in dogs occurs when dogs overdose on human beta-blocker medication, or are given an overdose of their own medication. Causes of the toxicity within the dog’s systems include:

  • Negative chronotropic and inotropic actions affect the cardiovascular system
  • The rapid blocking of adrenergic receptors
  • Depression of the central nervous system

Diagnosis of Beta-blockers Poisoning in Dogs

A very small amount of beta-blocker overdose can quickly result in toxicity. If your dog has overdosed on beta-blockers, call your veterinarian immediately. The veterinarian will perform a physical examination, including blood work, a biochemistry profile, and urinalysis. The veterinarian will be checking the blood potassium levels, as well as the blood glucose and plasma levels. The serum electrolyte levels will also be tested.  The physician will also come to a definitive diagnosis by observing the clinical signs, as he is aware that treatment must begin very quickly in order for the dog to survive.  It is important to communicate with the veterinarian the type and amount of medication the dog ingested.

The veterinarian will perform an electrocardiogram to check the heart rate and function in order to determine a slowed heartbeat, severe low blood pressure, and any other symptoms that may be associated with an overdose of this type of medication. The ECG will be a vital tool in diagnosing an overdose of beta-blockers, and when combined with the clinical signs, the veterinarian will be able to diagnose the situation.

Treatment of Beta-blockers Poisoning in Dogs

It is very important that treatment be started immediately to help reverse the effects of the poisoning. Treatment methods include:


Gastric lavage, a procedure used to flush out the toxins that were ingested, may be performed. This will also be followed up with the use of activated charcoal to help absorb any of the toxic substance. Vomiting may be induced in place of gastric lavage, and this depends on the amount ingested and what the veterinarian feels is necessary.


The veterinarian will closely monitor the dog’s blood pressure and heart rate. He will also monitor the bloodwork on a regular basis.

IV fluids

Intravenous fluids will be given to keep the dog hydrated and to help excrete the substance during urination. Intravenous fluids are also very helpful to stabilize the electrolyte levels and to help the kidneys continue to function properly. Calcium can also be given intravenously, and has been proven to increase the amount of calcium in the cells. Once the calcium is released into the cytoplasm of the dog, blood pressure can stabilize, cardiac output can strengthen, and inotropy can occur. 


In severe cases of beta-blocker toxicosis, insulin therapy may be given. This type of treatment option has recently emerged as being quite effective in treating severe beta-blocker toxicity. In some cases, IV lipid emulsion therapy is also used.

Recovery of Beta-blockers Poisoning in Dogs

If the dog was able to receive immediate treatment, and the dosage level was not too high, the prognosis is fair to good. Unfortunately, an overdose of beta-blockers can prove fatal in many cases. If your dog has survived treatment, your veterinarian may want to keep him for at least 24 hours to monitor his system. More than likely, your dog may be hospitalized for longer periods if he is stabilized and responding to treatment.

Once you bring your dog home, the veterinarian will give you directions on how to care for your dog. He will want to see him for follow-up visits to be sure he is recovering properly. He will also tell you what to watch for in terms of side-effects from the treatment or any new symptoms. If your dog begins to exhibit any new behaviors or symptoms, it is very important to contact your veterinarian.

My dog has been prescribed Sotalol for Congenital Heart Disease. He is prescribed 80mg twice daily. It was to be tapered up and today was his first day to receive the 80mg twice however my husband gave him two tablets in the morning instead of one in the morning and one at night. So he received an immediate dose of 160mg instead of it broken up in two 80 mg doses. He is 92 lbs. Should we be worried?

I accidentally dropped a 10mg propranolol tablet on the floor and couldn't find it. I saw my dog eat something off the floor but I'm not sure if it was that. Would 10mgs cause adverse effects?

If a 3kg chihuahua swalowed a 2,5 mg tablet of Concor beta blocker, how long would it take for symptoms to show?
the reason I am asking is that my dog was diagnosed with mitral valve disease and heart murmur of 5/6 and a suspected ruptured chordae tendinae. he had no clinical signs and was taking medication for it. my question is due to uncertainty whether i accidentally gave him my own half pill of Concor instead of his vetmed pill. he died 6 hours later without any symptoms. I want to ask how long after ingestion would concor show effect in his behavior? I repeat that i am fairly certain I did not mix up the pills, but since he did die, I want to rule out the poisoning possibility. thank you.

My dog is currently taking cerenia for an upset stomach, he had it about 8 am today. Tonight around 10pm he got a pill that my grandmother had dropped on the floor, it was atenolol 50mg. I realized what he had done and opened his mouth and got the pill out, it was still in an intact circle but the outside had slightly dissolved but not much. I wiped his mouth with a washcloth but I am scared the pill will harm him? Is it worth the trip to an after hours vet or should he be okay?

If you were able to retrieve the tablet from Wrigley’s mouth, I wouldn’t be too concerned; atenolol is used in veterinary medicine and the amount possibly consumed would be not significant. You should of course keep an eye on Wrigley for the time being to be on the safe side and visit a Veterinarian if you have any concerns. Regards Dr Callum Turner DVM

Beta blockers have a narrow safety margin and requires immediate veterinary care in cases of accidental ingestion. The type of beta blocker and the amount consumed will have a bearing on the overall prognosis; low heart rate, low blood pressure, lethargy and other symptoms may present. I wouldn’t wait for symptoms I would visit your Veterinarian or Emergency Veterinarian immediately. Regards Dr Callum Turner DVM

I dropped a 25mg metoporol and my 50 pound dog ate it. He just ate one. Should I be worried about this. I see dogs can be prescribed this drug also so I would think one pill would do much harm to him. Its been about 20 minutes and no symptoms as yet.
Thank you

Despite the use of metoprolol in dogs, the possible effects are not serious at this dosage but it would be best to induce vomiting using 3% hydrogen peroxide; there isn’t a lot of toxicology data on metoprolol in dogs but Buddy should be fine. If you notice lack of energy, fainting or any worrying symptoms visit your Veterinarian immediately. Regards Dr Callum Turner DVM
