Can Antihistamines Cause Heart Palpitations

Ventricular Tachycardia Following Ingestion Of A Commonly Used Antihistamine

The Causes of Heart Palpitations

Non-sedating antihistamines are available as “over-the-counter” preparations and have been widely promoted in public advertisements. However, two such antihistamines, terfenadine and astemizole, have been withdrawn in Australia and overseas. Their use was associated with ventricular arrhythmias QT-interval prolongation on the surface electrocardiogram and polymorphic ventricular tachycardia .13

We report a case of ventricular tachycardia which was probably “torsade de pointes” following ingestion of a single tablet of loratadine.

A 43-year-old woman presented after her identical twin died suddenly, presumably from cardiac arrhythmia. The patient was asymptomatic, had no other risk factors and was not taking any regular medication. Clinical examination showed evidence of mitral valve prolapse, with normal left ventricular function and trivial mitral regurgitation on echocardiography. Several ECGs and her biochemical profile were normal. An electrophysiological study did not show inducible ventricular arrhythmias with standard stimulation testing or adrenaline provocation. Atrial fibrillation was induced during catheter introduction into the right atrium, with ventricular rate less than 130/minute. A prophylactic automatic implantable defibrillator was subsequently inserted. Transient prolongation of the QT interval was noted on ECG monitoring in association with non-sustained VT within 48 hours of the implant.

So Why Are Decongestants Bad For Your Heart

You reach for a decongestant to help clear a runny, stuffy nose. A decongestant eases congestion by constricting the blood vessels in your nasal passages. This dries up nasal mucus.

But these medications can also abnormally stimulate the heart and blood vessels throughout the body. This can cause an increase in blood pressure and heart rate, or skipped beats. And it can interfere with your heart medications, Dr. Kaminski says.

If you have a heart condition, heart palpitations can last several hours after you take a decongestant. It is a dangerous and worrisome feeling that should be avoided at all costs.

What Causes Heart Palpitations

Heart palpitations can occur for a number of reasons. These include:

  • Psychological triggers such as stress, anxiety, or fear
  • Excessive exercise exerting too much pressure on the heart
  • Certain stimulants such as coffee, tea, and energy drinks. Drugs such as cocaine and amphetamines may also cause heart palpitations
  • Alcohol

Is It Safe To Stop Using Beta

Its dangerous to stop taking beta-blockers suddenly, even if youre experiencing side effects.

When you take beta-blockers, your body gets used to your hearts slower speed. If you stop taking them suddenly, you could increase your risk of a serious heart problem, such as a heart attack.

Contact your doctor if you experience unpleasant side effects with beta-blockers that last for more than a day or two. Your doctor might suggest another type of medication, but youll still need to slowly taper your beta-blocker dose.

A Look At Allergies And Heart Health With Tips To Endure Pollen Season Amid Coronavirus Fears

Cetirizine Dihydrochloride  An Antihistamine to Treat ...

Lea en;español

Spring brings warmer temperatures, blooming flowers and, for millions of Americans, the arrival of allergy season. It also coincides this year with the arrival of COVID-19, which could make allergy sufferers hyperaware of every sneeze and sniffle.

But there are key differences in symptoms. Seasonal allergies can cause sneezing, runny nose, itchy eyes and cough. Yet unlike allergies, coronavirus causes a fever, with other symptoms including cough and shortness of breath.

When seeking relief, people with allergies who are concerned about heart disease or high blood pressure must be especially careful when taking blood pressure-raising, over-the-counter decongestants. They’re also stimulants, which can increase heart rate.

But determining the extent of the direct connection between allergies and heart health is a topic that needs more research. A look at two studies offers examples of differing conclusions.

A 2016 study in the American Journal of Epidemiology examined the relationship between airborne allergen concentrations and emergency room visits for heart attacks in Ontario, Canada, from 2004-2011. The study found the risk of having a heart attack was 5.5% higher on days with the highest pollen levels compared to days with the lowest levels. Heart attack risk was highest in May and June, when tree and grass pollen are most common.

And her advice for patients still hasn’t changed.

Talking To Your Doctor

The good news is that antihistamines and anti-inflammatory choices are most likely safe even for people with heart conditions. However, if you are actively taking medications for high blood pressure this may not be the case. You may experience heart palpitations while taking allergy medications as well, but in healthy individuals this is usually not cause for concern. While this is general information, it is always recommended that you discuss any medication changes with your doctor even if they are minor or over the counter, because everyones situation is unique.

The good news is that you can ease your allergy symptoms by taking simple steps at home that reduce your exposure to pollen, without putting you at risk if you have high blood pressure. Keeping your car and home windows shut and leaving your shoes outside are just a couple of ways to prevent pollen from lurking in your clothes and home. While allergy medications are usually fairly safe, you never know exactly how your body will react, especially if you suffer from heart disease or a heart condition.

What To Do If Foods Cause You Heart Palpitations

  • Shortness of breath
  • Pain or discomfort in the upper back, arms, neck, or jaw
  • Feeling of impending doom

If its the first time youve ever noticed heart palpitations, make a follow-up appointment with your doctor. Its likely nothing is wrong, but its always best to err on the side of caution and make sure that the food-related episode isnt the first sign of a bigger issue.

Next, start a log and record times when the palpitations recur. Note what you ate or drank and what sort of emotional state you were in. If specific foods or beverages tend to cause recurrences, take that as a sign you should reduce or eliminate those foods from your diet. Your body and your heart couldnt be telling you any more clearly that those substances are doing you harm.

Zyrtec & Cardiac Side Effects

Histamine is a substance produced by the body in response to allergic reactions that triggers immune response symptoms such as watery eyes, runny nose, and sneezing. Antihistamines are a class of drugs that block the action of histamine and reduce these symptoms. Older antihistamines had many side effects such as severe drowsiness. Newer antihistamines, called selective H1-receptor antagonists, do not cross into the brain and have fewer side effects. In 2007, the FDA approved Zyrtec, or cetirizine, as an over-the-counter drug to treat allergic rhinitis and chronic urticaria, a skin condition characterized by recurrent hives 2.

If you are experiencing serious medical symptoms, seek emergency treatment immediately.
