Lexiscan (regadenoson) "Immediately after the Lexiscan was injected, lightheaded, dizzy, nauseated, an uncomfortable substernal feeling, my arms and legs felt weak, a very brief strong urge to defecate, followed by severe abdominal pain that persisted for hours! I developed numbness in my feet and a crampy pain in both calf muscles that lasted all day. They gave me a large cup of regular coffee to reverse the drug. This helped but only temporarily. That evening, I started feeling really sick - not actually nauseated but I had no desire to eat. The substernal discomfort lasted for 2 days. The weakness, generalized fatigue and muscle aching were still present more than 9 days after the test, severe enough to prevent me from being able to do many of the basic things that need to be done every day!"

Lexiscan (regadenoson) "The assistants are not RNs. They believed the 1/2 life is 15 seconds. Online info is good, but education about this is non-existent before the test. No reversal agent used. I think it should be mandatory. Still have headache and tired eyes, 3 hrs. after."

Lexiscan (regadenoson) "I had an anaphylactic reaction. Within 30 seconds of the drug being injected, my chest began to tighten, and I could not feel my feet. The numbness continued to spread upward until I could feel nothing from my chest down, with continuing increased chest pain and wheezing. They placed me in reverse Trendelenburg position and called for a cardiologist. I became increasingly diaphoretic, increasing chest pressure, still unable to feel anything below my neck, and I could not move my head. I received several IV pushes. It took them over 30 minutes to stabilize me and return me to baseline-able to move all four limbs with normal vital signs. This occurred within a hospital setting, but they proceeded with the test anyway. I am asthmatic on meds."

Lexiscan (regadenoson) "This is for all the folks that will be getting Lexiscan for a nuclear test. I read the reviews here and was prepared for the very worst. When I got the injection, I waited and steeled myself for side effects. Nothing. I mean nothing at all. Please, please don't worry about the injection. You may well have a non-experience like I did. My guess is there are oodles of people that didn't have a reaction and so didn't write a review."

Lexiscan (regadenoson) "I was admitted to the hospital due to high blood pressure and chest pain. The stress test using Lexiscan was one of the tests I did. The RN told me I would be feeling my heart pounding as I was exercising, and that some people would feel nausea too. The technician waited for a cardiologist to be present before the drug was injected. The first thing I felt was warmth taking over my heart. Then I started to feel pressure. The RN advised me to move my feet as it made people feel better, according to her. I believe the test lasted 10 minutes or a little bit less. They reminded me to take deep breaths. I felt a lot of nausea too. It took a lot of mental effort to go through this test, especially to avoid getting into panic mode. The nurse waited for my heart rate to go down before I was taken to another room. After that exam, I felt extremely tired for over 24 hours. My heart rate would go up from simply walking to the bathroom during one day. I started feeling better after the second day."

Lexiscan (regadenoson) "Today I had a nuclear stress test with Lexiscan and thallous chloride (Tc-99m rapidly becoming unavailable). As a former nuclear medicine tech, I used to give these tests, most of which were conducted with Persantine; I would advise the patients that they would briefly feel like an elephant was sitting on their chest. I was a bit apprehensive about the stressing agent but noted absolutely no effects from it. I'm impressed."
