For Nausea/Vomiting "Cyclizine stopped the sickness, but the side effects were horrendous. The first made me feel lightheaded and drowsy. The second made me agitated and stopped me from sleeping. It also gave me palpitations and a sense of dread. Awful medication, I will never take it again. Disappointed the doctor prescribed it, I really wish I hadn't had them."

For Nausea/Vomiting "I'm emetophobic (fear of vomiting) and have these pills for any times I get sick or feel really nauseous. They do get rid of the nausea, but they come with a lot of side effects. They make me incredibly drowsy, to the point where I have to sleep. If I fight it, I get this 'high' feeling where I'm disoriented and not fully aware of the passage of time or what's going on around me. I get super dizzy and feel all floaty and strange. The weirdest symptom is every time someone speaks or I hear a loud noise, it feels like my brain has fallen out of my skull or like I've just dropped several feet. They do work to get me to sleep, but if I wake after a few hours, I can still feel the confusion and dizziness side effects."

For Nausea/Vomiting "I’m on cyclizine for pregnancy sickness and nausea. It definitely works for mild nausea and prevents me from vomiting, however, cyclizine makes me incredibly sleepy and drowsy. I feel like I’m “high.” Definitely can’t leave my house or drive after each pill."

For Nausea/Vomiting "I have a condition called Cyclical Vomiting Syndrome (CVS) and am often hospitalized due to persistent vomiting. Having cyclizine injected through the cannula into the vein is the only thing that helps. It does make me feel very drowsy and sometimes gives heart palpitations in injection form, however, this is a welcome break at the time. I find the medication very useful, and the tablets work reasonably well too for preventing the feeling of nausea."

For Nausea/Vomiting "Was prescribed this to counteract nausea from another medication. The first day I took it, I felt so “high” and awfully drowsy, could do nothing but sleep. Every time I take it, I normally get that same “high” feeling along with trembling and drowsiness. I kept taking it because it was fixing the nausea, and I could go to sleep straight away. 5 months later, for whatever reason, I experienced much different side effects. Struggling to breathe, throat felt like it was closing slightly, stomach pains, headache, hot chest, nervousness, irritated sinuses, and sweats. Definitely would not be taking again despite the fact it’s helped me for so long!"

For Nausea/Vomiting "I have unexplained nausea that has been going on for about a month. The doctor gave me cyclizine. It does help with nausea for sure but I've experienced some weird side effects, e.g., knocks me out for a good few hours and I had to take one at work. I felt awful. I honestly felt like I was having a bad trip. Made me unbelievably anxious, heart palpitations. I was so drowsy and I couldn't even walk because I felt like I was going to pass out. I'm not sure if I'll be taking it again but it's the only thing that helps with nausea :("
