For Nausea/Vomiting "Following surgery, I was administered cyclizine IV for nausea and had an immediate adverse reaction. My whole body was shaking, my teeth were chattering uncontrollably, I was losing sensation in my hands and feet, and felt like I was falling into blackness. I had tightening in my chest and chest pains with an increased heart rate. For 1 1/2 hours after it was administered, I was unable to pass urine, although I was absolutely desperate. My heart rate remained higher than usual for the following 8 to 10 hours, and I was unable to sleep also. I have now noted this drug with my GP and will take extra caution next time. My nurses told me I was having a panic attack as I probably wanted to pass urine after my surgery. This was far worse."

For Nausea/Vomiting "To cut a long story short, I got septic from a failed appendicitis operation as a teenager. On morphine to help with the pain, I got the sickness and spent some time on another antiemetic. This stopped working eventually, so I was given a cyclizine injection. I vividly remember my leg going into convulsions, watching the fear in my mum's face as she stood by, then my whole body shaking uncontrollably with sweats. I passed out soon after, woke up with no idea how much time had passed but was told I was allergic to it. Horrible reaction to a horrible drug."

For Nausea/Vomiting "I had unexplained sickness, where I had unbelievable stomach pains. Drs weren't sure what was wrong, but they gave me cyclizine to help. I felt awful, was totally manic, flushed, and my heartbeat was very rapid. Turns out I am allergic to it. Terrifying experience, but luckily I was given another drug to counteract the symptoms. Was lucky I was in the hospital when I took this."
