After a recent episode of SVT, my cardiologist prescribed Adenosine 12mg/4ml to be given by IV push. The medication is supposed to quickly stop the rapid heart rhythm, but I'm nervous about the potential side effects. I've read that it can cause flushing and shortness of breath, but what if I experience something more severe? Has anyone here had experience with this medication? What were your experiences like? Any tips or insights would be greatly appreciated. I just want to be prepared for whatever might happen.

Were you able to get any information about the injection process? Like, how long does it take to administer?

Adenosine is a fast-acting medication, so you might feel the effects pretty quickly. Just remember, the short-term side effects usually pass within a few minutes. The one time I had really bad dizziness, so prepare for that. I don't want you to worry too much, though—tons of people have taken it without any major issues.

I've heard that adenosine can cause some really strange neurological symptoms. Is this something I should worry about?

I've had adenosine before and had a bit of flushing, which went away quickly. No big issues, but it's always smart to be prepared and know the signs of a bad reaction.
