Ozempic<\/span><\/a> is the brand name for semaglutide, which is a medication that\u2019s FDA approved to treat high blood sugar in people with Type 2 diabetes. It is also often prescribed off-label as a weight loss medication, even in patients with normal blood sugars. Ozempic is a type of medication called a<\/span> glucagon-like peptide-1 agonist<\/span><\/a> (GLP-1) and is only given by injection.<\/span><\/p>\n

If you are taking Ozempic and notice symptoms of heart palpitations, fast heart rate, heart flutters, or irregular heartbeats, you might be wondering: Can Ozempic cause heart palpitations? The good news is that heart palpitations are uncommon<\/span> side effects of Ozempic<\/span><\/a>, and if you are experiencing them, they can be managed.<\/span><\/p>\n

What to know about Ozempic and heart palpitations<\/span>\u00a0<\/span><\/h2>\n

While some people get heart palpitations while taking Ozempic, it\u2019s not very common. Additionally, this symptom is not found in medical literature about the medication or in clinical trials. For example, it\u2019s not listed as a side effect in the FDA\u2019s 2025 prescribing information.<\/span><\/p>\n

\u201cAs a pain management doctor, I see a lot of patients taking Ozempic, whether for diabetes, weight loss, or both,\u201d says Sean Ormond, MD, dual board-certified in anesthesiology and interventional pain management physician at Atlas Pain Specialists. Like any other medication, Ozempic has side effects, Dr. Ormond says. But heart palpitations aren\u2019t typically one of them.<\/span><\/p>\n

Still, heart palpitations can happen when people take Ozempic. \u201cSome people on Ozempic notice their heart skipping beats, racing, or fluttering, especially when they first start taking it or after a dose increase,\u201d Dr. Ormond describes. \u201cMost people don\u2019t have this issue, but for those who do, it can feel unsettling.\u201d<\/span><\/p>\n

According to <\/span>Hosam Hmoud, MD, cardiology fellow at Northwell Lenox Hill Hospital, while the research and clinical trials we have so far on Ozempic and other<\/span> GLP-1s<\/span><\/a> don\u2019t include heart palpitations or arrhythmias as side effects, some studies have actually shown the opposite. \u201cThere has been a growing body of literature demonstrating the protective and mitigating effects of GLP-1RA for significant arrhythmias such as atrial fibrillation,\u201d Dr. Hmoud shares.<\/span><\/p>\n

One example of this is a meta-analysis published in <\/span>Frontiers in Cardiovascular Medicine<\/span><\/i> in 2022. This study found that GLP-1s may be linked to a reduced risk of arrhythmias, especially among people with<\/span> Type 2 diabetes<\/span><\/a> who have myocardial infarctions (heart attacks).<\/span><\/p>\n

Causes and risk factors<\/span><\/h3>\n

There are several possible reasons why someone may experience heart palpitations while taking Ozempic. According to Dr. Ormond, one possible reason is that<\/span> Ozempic affects digestion<\/span><\/a>, which can impact the nervous system, and in turn, the heart. \u201cIt also impacts blood sugar and hydration levels, which can sometimes trigger palpitations,\u201d Dr. Ormond describes.<\/span><\/p>\n

Additionally, Dr. <\/span>Hmoud notes, people who take Ozempic may have underlying health conditions that may cause heart palpitations, independent of Ozempic use.\u00a0<\/span><\/p>\n

\u201c<\/span>It’s important to consider that patients taking GLP1-RA may have other comorbidities that can contribute to palpitations\/arrhythmias such as GI symptoms leading to electrolyte imbalances, diabetes, chronic kidney disease, and a weakened heart muscle (heart failure),\u201d says Dr. Hmoud. \u201cWhenever I see a patient for suspected arrhythmias or frequent palpitations, I always check their blood work to ensure normal electrolyte balances and organ function as well as heart function with a cardiac sonogram (echocardiogram).\u201d<\/span><\/p>\n

What about drug interactions? As Dr. Ormond explains, use of<\/span> stimulants<\/span><\/a>, certain<\/span> blood pressure medications<\/span><\/a>, or<\/span> thyroid medications<\/span><\/a> might increase the risk of experiencing heart palpitations while taking Ozempic. The higher the dose of Ozempic you take, the greater the risk.<\/span><\/p>\n

How to manage and treat heart palpitations<\/span><\/h2>\n

When it comes to managing heart palpitations while taking Ozempic, each person is unique. You should seek medical advice from your healthcare provider about your specific situation.<\/span><\/p>\n

That said, you may not need to stop taking Ozempic if you experience heart palpitations. \u201cI would not change the dosage or stop a GLP1-RA in the setting of arrhythmias or palpitations,\u201d Dr. Hmoud says. \u201cI would first obtain a detailed patient history, blood work, echocardiogram, and medication reconciliation to identify more common causes of palpitations\/arrhythmias.\u201d<\/span><\/p>\n

Additionally, making some<\/span> lifestyle changes<\/span><\/a> may be helpful in this situation. \u201cStaying hydrated, making sure your electrolytes (like potassium and magnesium) are in check, and cutting back on caffeine and alcohol can help,\u201d Dr. Ormond says. Since stress can also be a big trigger for heart palpitations, taking time to destress, or engaging in practices like meditation and relaxation exercises, can help.<\/span><\/p>\n

If your doctor recommends it, it may also make sense to wait patiently. If your heart palpitations are mild and only occur occasionally, they may decrease as your body adjusts to the medication, Dr. Ormond says.<\/span><\/p>\n

\u201cBut if they keep happening, get worse, or come with dizziness, chest pain, or shortness of breath, call your doctor,\u201d he advises. \u201cYou might need a dose adjustment, a medication switch, or some tests to make sure nothing else is going on.\u201d<\/span><\/p>\n

\u00a0<\/b>Alternatives to Ozempic<\/span><\/h2>\n

Although unlikely, in some cases, your doctor may advise you to stop Ozempic altogether. But that doesn\u2019t mean you have to stop taking Type 2 diabetes medication or weight loss medication.<\/span><\/p>\n

Some<\/span> Ozempic alternatives<\/span><\/a> to consider include, according to Dr. Ormond:\u00a0<\/span><\/p>\n
