... taking it and had to stop because they got so bad. Unfortunately, they are still occurring even though I have been off the drug for almost 3 months. Has anyone else had this experience? I am sure the palpitations are not anxiety related.
Has anyone experienced heart palpitations after taking Lexapro? I developed palpitations soon after?

alpha23; Yes this sure could have started off from the Lexapro but no way should it go on for 3 months from one table. You should really just make sure with you GP doctor anxiety or whatever it can show up in many different ways but please get it check out

Hi, alpha! Palpitations CAN be a rare side effect of Lexapro, but Lexapro's half life would have it cleared from your system within a week at the most.
If you're sure it's not due to anxiety you might consider contacting your doctor for a diagnostic work-up.
Best regards and I hope you feel better soon.

I know from my own experience while taking Lexapro that it does in fact cause palpitations even several months after I stopped taking it. I did notice that candy including chocolate and caffeine products also contribute to the palpitations. I don't know if you use these products but if so, try to lessen the intake and see if you notice a difference. If you have anxiety, that too will cause palpitations. It certainly can't hurt to talk to your Dr about this. Good luck.

Hi Robyn, thanks for your answer - it's reassuring to know I'm not the only one to experience palpitations several months after stopping Lexapro. Have your palpitations calmed down now? I also noticed that caffeine and chocolate have an adverse effect, so I've cut them out from my diet. Thanks once again for your response!

No problem! Yes, the palpitations have just recently started to calm down and it's been about 7 months since I weaned off Lexapro. If you feel any anxiety and start getting palpitations from it, do the slow breathing exercises (in thru the nose and slowly out our mouth) a few times and they will calm down. Keep in mind too that your brain is now releasing it's own serotonin as opposed to Lexapro doing it so your body is still adjusting. Try not to worry. All will be okay!

Hi, I started on 5mg Lexapro yesterday morning for anxiety and I been having palpitations all day and night. I feel restless it made me feel worse. I was very dizzy and my stomach felt sick. I will suspend the use today. I was given Lorazepam 00.05 mg to give me extra kick. I took both medicines yesterday and made symptoms worse. I started having anxiety in May and I been taking Lorazepam as needed every other day. Yesterday I finally decided to give Lexapro a try. I will suspend treatment. Please read this: Logo for WebMD

Some Antidepressants Tied to Irregular Heartbeat
FROM THE WEBMD ARCHIVES
TUESDAY, Jan. 29 (HealthDay News) -- People taking certain antidepressants, including Celexa and Lexapro, may have a slightly increased risk of developing an abnormal heart beat.
Researchers say the drugs, which are in a class of medications called selective serotonin reuptake inhibitors (SSRIs), may extend the length of electrical activity in the heart, called a QT interval. A long QT interval is an indicator of abnormal heart rhythms.
"For people who are taking higher doses of citalopram (Celexa) or escitalopram (Lexapro), they should discuss these doses with their doctors," said lead researcher Dr. Roy Perlis, director of the Center for Experimental Drugs and Diagnostics in the psychiatry department at Massachusetts General Hospital in Boston. I was reading this on the internet. I hope this helps. Thank you

I quit taking lexapro about 3 months due to it causing palpitations. I am still having palpitations but they have calmed down quite a bit. I know these palpitations aren't from anxiety but how long will these last? Has anyone stopped having them completely?

It's hard to say how long the palpitations will last, but it's a good sign that they have calmed down quite a bit. How long were you on Lexapro and how long since you quit?

It's been about 3 months since I quit taking it and I still have at least 4 palpitations a day it's starting to get old.

It sounds like the palpitations have calmed down a lot for you. Things will continue to improve over time, especially if you are not taking any other medication.

I got on Lexapro due to having palpitations daily and five days later I woke up from the most intense heart racing panic attack. I was up to 175 and the feeling with it was super intense, I had attack after attack (smaller ones) for about 4.5 hrs. This is the second time recently I tried Lexapro and I just can’t take it so I am now trying Zoloft. Just looking for some relief.

Has the Zoloft helped you? I just started Lexapro and I am having heart palpitations. I am looking for something that will not cause them but will help with my anxiety and depression. Thanks

I had been having issues with palpitations which I believe was due to diet. I saw the doctor about the palpitations to check out other potential causes. In addition to running a bunch of tests, she prescribed Lexapro for potential anxiety as a cause. There was a week's delay in getting the medication, at which time I changed my diet and the palpitations ceased. Then I started taking the Lexapro. I've only been on 10mg once a day, for four days and the palpitations started again. Didn't think it was related as I had started a new food plan, and thought this was the cause. Two days into taking Lexapro, I had skipped heart beats again. Yesterday, I had skipped beats for two hours, and had the sensation of feeling nervous, jittery; I knew it wasn't the lectin free diet I was on. I also experienced skipped beats during the night, which was unusual for me. So glad I decided to google if anyone else was experiencing this. I'm discontinuing Lexapro today.

"Cardiovascular
Common (1% to 10% of users): Palpitation
Uncommon (0.1% to 1% of users): Abnormal ECG, hypotension"
"Psychiatric
Common (1% to 10% of users): Agitation, anxiety, nervousness, restlessness"
"Some side effects of escitalopram may occur that usually do not need medical attention. These side effects go away during treatment as your body adjusts to the medicine. Also, your health care professional may be able to tell you about ways to prevent or reduce some of these side effects."
"Side effects have been reported to be generally mild and transient. They are most common during the first 2 weeks of treatment and decrease in intensity and frequency with continued treatment. They generally do not lead to treatment cessation."
Although these side effects should be reported to your doctor they aren't generally cause for concern.

I took Lexapro for 4 weeks at 5 mg. After two weeks I developed a premature heartbeat (assuming this is the same as a palpitation). I got off the medicine about 2 weeks later. The palpitations were less intense and less frequent after quitting, but were still there. I'm now 4 months off of the drug and still have 4 - 8 events a day. I've worn a 30 day heart monitor and they diagnosed it as a benign arrhythmia. I never had that before taking the drug so I think it is a fair conclusion to say this is all a result from the drug. They now want to put me on a Beta Blocker which I really don't want to do. Just curious if anybody else was told to try a Beta Blocker and if it worked? For those that had it resolve on its own did you do anything special to help it go away?
Cheers!

Hi Heels, I would avoid taking the Beta Blocker if at all possible. It will have its own side effects and you don't want to become dependent on it long term. It took me about 9 months for the issue to resolve itself, so even though you are 4 months off the drug I would wait to see if it gets better on its own. One of things that can be helpful for palpitations is Magnesium supplements. If you are interested, I would suggest googling "magnesium and palpitations" to see what supplements other people have found helpful. There are a lot of different types of Magnesium, so you want to make sure you get the right type. I also found moderate exercise to be very helpful. At first it was just walking, but I built up to jogging and then running. Finally, one of the most important things you can do is try your best not to focus on the palpitations because anxiety about them will only make them worse. I know this is easier said than done, but it is very true!

I took Trazodone and Lexapro (both 25mg) for only 3 days and woke up in the middle of the night to my heart not beating, then suddenly racing. Obviously went to the ER as I thought it was a heart attack. When I was at the ER, my heart did that a few more times but slowly went away over time. The episodes being about 5-30 min separated from one another. That was Oct. 31, 2020. Leaving the ER they had diagnosed me with (SVT), and had me start taking Metoprolol (25mg). Had extreme discomfort in my chest for a couple days (pounding, fluttering) and it happened again 3 days after the initial one on the 31st. Went back to the ER and they said it was Palpitations but recommended I put on a 24-hour Holter, and my PCP switched me to Atenolol (25mg). I felt good for a couple weeks after that, and in the time of me feeling good for those couple weeks (although still having minor discomfort with pounding in chest laying down) I had the Holter on but it caught nothing.
Then, two weeks after, around Nov. 14, it happened again, but it wasn't as bad as the initial one pounding wise, but I had a severe shake in my whole body that was uncontrollable. This time I went to the ER they did all the tests they could and said my heart was normal and told me it was just palpitations.
I've had a LOT since then, each one not as bad as the last but they've become more frequent. Now I have a bit of dizziness, sharp pains in the back of my neck sometimes, flushing in the face, I can't sleep on my side as much anymore.
Just yesterday morning I was sleeping on my right side when I woke up, the right side of my chest was numb. No pins and needles feeling, but it was numb. I had a 2-week monitor on that I've yet to get the results back from. I can't find anything online that helps. This is the closest thread to what I've experienced. Hoping I can get a reply.

I started Lexapro on 10/6 10mg I took it for three days. All three days had severe heart palpitations most of them being while I was trying to fall asleep. Also kept waking up to feeling like I wasn't breathing and had to catch my breath. None of that was happening before I started the medication. Yesterday 10/9 I did not take the Lexapro bc I decided it wasn't right for me and it causing this to happen was not worth it and scares me. Last night I still had some palpitations but no where near as many. I know it takes some time to get out of your system but I am hoping once it is out that they stop completely. This seems to be a common thing to happen to people that start this medication which is concerning to me.
