FDA Approved Drugs and User Comments: ADENOSINE

User Comments:

For Supraventricular Tachycardia: “I was given this drug one evening when already in hospital for an unrelated infection. I’d felt palpitations for a while but when they did my routine obs my heart rate couldn’t be read. They called in a cardiac team who swiftly entered my room with all sorts of machines, they hooked me up to a more sophisticated heart monitor and my pulse was 236bpm, the doctors couldn’t understand why I was so calm (I was just used to them so just assumed as it usually went away that it would do the same this time) I was warned that the drug could make you feel “an impending sense of doom”. I had to have 2 doses and to be honest I didn’t have any adverse reaction, the 2nd dose got my bpm back to normal straight away!”

For Supraventricular Tachycardia: “I had undiagnosed supra ventricular tachycardia for a couple years. Episodes lasted a minute or so and would pass after holding my breath and bearing down. In August 2015, I was at a clinic on a hospital campus when the SVT started. It didn’t stop and continued to go faster. The doctor had them call the paramedics and the EKG showed my heart rate was 220. On the way to the ER, I got an IV and adenosine, as my heart rate was still increasing. It was the weirdest, scariest feeling, like the intense pressure of being on a roller coaster heading downhill, and breaking really hard. It passed in seconds, my heart rate was down to 130, then was a more normal 80 when they released me 4 hours later. I didn’t enjoy it, but it helped me immensely.”

For Supraventricular Tachycardia: “I have had this given through IV 2x and each time it cause my heart rate to go up to 200 and up, it never lowered it. Yes I had the crazy heavy feeling (like an elephant is on my chest) couldn’t breath and was hot and dizzy not good! I will not allow doctors to inject this while having an episode I get another medication that works for me. Unfortunately adenosine doesn’t!”

For Supraventricular Tachycardia: “Could not control my heart rate naturally after going into SVT of 200 bpm. Tried bearing down, breathing techniques, but nothing worked. Had my wofe drive me into the ER where they prepped me for an IV and then gave me Adenosine. First time ever I had taken it for my SVT in the 36 years I have had it. It dropped my heart rate instantly to 130 then down to 90. I was amazed and relieved. I still prefer controling it myself but it is good to know there is something out there that works to control it when all other ways fail. I had no burning experience like others did. I do have a cottony feeling head and extreme tiredness 2 days after but that seems to come with a 1-2 hour 200bpm episode.”

For Supraventricular Tachycardia: “This drug was given to me when I was totally unaware of what was going on. I was transported 60 miles to nearest heart center. Given to me a second time in 12 hours. I was aware and let me tell you it was painful in my chest and then I got an intense headache. The doctor tried to get me to take the drug a third time about 24 hours later, and I said no! I ended up putting my head into a bucket of ice water to get my heart rate back down to normal. There are ways to do things with out chemicals! over and over again!”

For Supraventricular Tachycardia: “Heart ramped up to 200 bpm. Received two doses of adenosine in ambulance as first dose didn’t work. EMT’s warned me it would cause some pretty unpleasant feelings. Intense burning and pressure occurred instantaneously, from my head to my toes. It was pretty horrific, but short lived. I even manged to joke how excited I was to receive a second dose and experience it again. Heart rate was in upper 90’s by time I was settled in emergency room at the hospital.”
