Regadenoson for Radionuclide Myocardial Perfusion Study "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!"

Regadenoson for Diagnosis and Investigation "Scary... extreme and rapid shortness of breath... bad headache that went behind eyes and towards the end of the test, nausea. Would never agree to this test again. Cannot believe this is appropriate or safe for anyone like me who has had a STEMI and coronary artery disease. Also, shouldn't BP be monitored several times throughout the test?"

Regadenoson for Diagnosis and Investigation "I had this test today. I did feel somewhat dizzy and flushed, but for only a couple of seconds. I did get a headache that did not go away, so they gave me the antidote and it went away almost right away. It was not as bad as I had expected. The only thing I am wondering about is later in the day I became very nauseated. Not sure if this was from the medicine."

Regadenoson for Diagnosis and Investigation "Had it used for a stress test at a local VA Medical Center. Had mild chest discomfort, mild discomfort in both legs, and raised pulse. Not as bad as expected, no nausea or other side effects. Do not worry if you are asked to have a stress test using it."

Regadenoson for Diagnosis and Investigation "When the Lexiscan was injected in the IV on Oct. 1, 2019, immediately the adverse reactions started with shortness of breath, nausea, headache, tightness, jaw pain, and stiffness, as well as dizziness. Upon rising up, a nitro was administered, but still could not eat anything afterward, but did intake liquids (Sprite) to help nausea. This was definitely a cakewalk compared to 2018, which the Lexiscan helped indicate my 95% blockage. I think if Lexiscan helps any cardiologist save a life, then the minor adverse reactions are worth it."

Regadenoson for Diagnosis and Investigation "I was injected with the Cardioli te first, waited approximately 30 minutes, pictures taken, and then injected with the Lexiscan for the stress test. I became extremely sick after leaving the exam room. My thighs were in cramps, pain in my left arm, and vomiting. Took hours for it to wear off. Was I allergic to medicine?"

Regadenoson for Diagnosis and Investigation "I was very stressed for my Echo and Lexiscan, but I had both this morning, and I had a little shortness of breath, facial redness, headache, nausea, but they gave me meds that made me feel better 15 to 20 minutes later. Everything went fine, less than I had expected, surrounded by staff that were with me every step of the way. Nothing to it. Easy."
