For Sedation "Please be careful with these. About 3 years ago, I took some to get a few hours of sleep. I had to ask the pharmacist for them as they were kept behind the counter. I got the 25mg tablets and had no idea how strong they were. I’m embarrassed and still feel humiliated by what happened. I took 2 at first, I honestly thought they would just give me a few hours of sleep and nothing else. I was hallucinating! I won’t go into great detail, but I thought my family were in the house with me, they weren’t. My family and neighbor told me some of the things I did. They ended up calling an ambulance. I wrote to the company and also did a long internet search which I discovered that one rare side effect was, in fact, hallucinating. Please be careful with them. A big lesson learned, always take as prescribed."

For Sedation "I took two to get some sleep as I suffer from insomnia, and we had a family gathering the following day. Still hadn't fallen asleep by 5 am, so I took another one. Family turned up, I don't remember. I thought there were worms crawling in my carpet, I was talking to a mop, which I thought was a person, thought I saw millions of baby spiders on the walls. I lost track of about 36 hours and was hallucinating the entire time! After doing an internet search, I found out they can cause hallucinations! They should have it on the box. I wrote to the company but never heard back. I was so embarrassed and felt humiliated in front of my family. At one stage, they phoned for an ambulance. PLEASE be careful with them."

For Nausea/Vomiting "Do not use this medication for anyone over 60. My mother was given this in the hospital for a mild nauseous feeling. I think they thought she would be sedated by it. She is elderly. This drug put her into a terrible state of hallucinations, delirium, and all-around restlessness for about 8 hours. It’s awful. She would have been better off with Tums. Be aware of all the side effects."

For Allergic Reactions "My son was given a one-time dose of 25 mg of this drug intravenously for nausea in the hospital, while on IV drips which included nitroglycerin, blood pressure medications, and pain opiates. He had a *severe* reaction, which included extremely high BP spikes (over 200 systolic), seizures, disorientation, and hallucinations. The blood pressure spikes and seizures were extremely dangerous, as he had just suffered aortic dissection. It was fortunate that this drug reaction was not fatal. This drug should have a huge warning against usage with blood pressure meds, as that is a potentially fatal combination. The pharmacy should reject any request to use this drug in such a combination."

For Nausea/Vomiting "My wife has taken this medicine in pill form to combat nausea due to chemo, with no adverse side effects. Last week, she was given a dose via her central line. She became psychotic and combative. Phenergan via IV was not good for her. Zofran is an excellent alternative."

For Nausea/Vomiting "It took care of the nausea, but the hallucinations that came with it were a very unwelcome side effect."
