I've been diagnosed with SVT and my doctor prescribed Adenosine 6mg/2ml Syringe. I'm a bit nervous about the side effects, especially the ones that require immediate medical attention. I've heard it works fast, but I'm not sure what to expect. Has anyone here used this medication? I'd love to hear about your experiences and any tips you might have. Also, is it true that the side effects only last a short time? I've read that it can cause flushing, shortness of breath, or chest discomfort, but it's comforting to know it should pass quickly. I'm just not sure what to expect when it comes to the more severe side effects — do they happen often? Any advice on how to prepare for this would be greatly appreciated.

I got it in the ER. They told me it might feel like a brief terror of death, but it works. It's called Adenosine. You know, it’s like your heart gets reset. Be prepared for that moment when you think you’re dying, but it passes quickly.

I've been using adenosine for a while now. It's a bit scary at first, especially the first time you get it. The dizziness went away quickly for me, but the flushing was intense. Bring a blanket if you can, it helps to shield you when you get flushed. It's definitely worth it to get your heartbeat back to normal.

Who else has felt like they were dying when they first got it? Definitely a rollercoaster of emotions.

Side effects are usually short-lived, but be prepared for them. Make sure you have someone with you when you take it, and lie down if you feel dizzy. And keep your doctor informed about any changes in your symptoms.

Don't use it if you have asthma. My friend has asthma and had a pretty bad reaction but it lasted for a few minutes and he was fine.

I'm an ER nurse, and I can tell you, adenosine works like a charm but the patient reaction is always a bit scary to watch. Make sure you're with someone when you take it for this reason.

I got it in the ER a few years ago when I had an SVT episode. The nurse warned me about the feeling like you're dying but I was so out of it that I just fainted from relief that it stopped.

I've had it once, and honestly, the worst part was the fear of missing out on the race after the race. The adrenaline was still there when my doctor came. The side effects didn't last long, but the excitement from this experience was long-lasting.

Make sure you tell your doctor about any previous reactions to medications. My mom had a really bad reaction to it. She was on the ground after she was injected.
