"My partner was prescribed 25mg to take each night as he wasn't sleeping. The first night he took one, it wiped him out, and he was soaking with sweat. I had to help him get undressed and into bed, he was that drowsy. The next day he looked drugged up. Then the second night he took another and never woke up, he passed away in his sleep. I thought he was just sleeping until I found him. The post-mortem came back unascertained, and I have been told it will take anywhere between 6-8 months to get an answer. However, this is the only new medication he had taken. His other meds he took regularly, so I blame this. Please be careful with this drug."

"I suffer from PMS and insomnia. I tried all types of herbs and supplements for sleep aids, even Melatonin, which worked for me for a couple of nights, but I'd be back to the same thing - waking up at 3 am or not sleeping more than 3 hours a night. My GP told me about Phenergan. I took the 25mg dose 2 hours before bed for 5 nights, and it 100% worked. I am able to carry on month by month with great sleep. Wonder drug, thank you Phenergan, my friend."

"This stuff is garbage for sleep. My doctor put me on this & took me off Zolpidem, which worked great. Why screw with what works? Promethazine may work for people with mild sleeping issues, but for those of us with severe insomnia, it's like taking a skittle candy. Doesn't do a thing!"

"I took 25mg Phenergan to help me sleep. It worked! I've been taking it for almost 2 years but only recently realized, when I stopped taking it, that it was causing me to have a low mood and a REALLY dry mouth to the point where I needed a drink with me at every meeting because it would affect my speech. When I stopped taking it, I woke up 4-5 times in the night, which is normal given I've got small children, but woke in the morning feeling a lot more clear-headed, less headaches, and didn't have the need to guzzle glasses of water! Pharmacists only ever warned of drowsiness but not these side effects so wanted to share them with everyone! This medicine will get you to sleep, but it comes with a significant cost!"

"I found half a 25mg tablet good for sleep. Can take hours before it starts working. The first time you take it, it works wonderfully. Be mindful it is an old antipsychotic and has a long half-life, so what that means is it builds up in your body. Always start on a low dose of 10mg and increase when needed. High doses can give you restless leg syndrome as it drops your dopamine level. It can also suppress breathing - not ideal! Best taken an hour before bed as its plasma peak is approx. 2 to 3 hours (the most effect) although that time level is dependent on your rate of metabolism. I am horrified reading how many people double the max recommended dose when they take the first time, not knowing how it affects you."

"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."

"I've used Phenergan, which is sold over the counter, as a sleeping aid for about one year now. Taken one hour before bedtime, it rarely fails to put me to sleep. The wondrous thing is that I have kept the same dose, and there are no withdrawal symptoms if you stop using the drug for a week or two. Definitely the best substitute for any prescription sleep aid that I've ever tried. Highly recommended as a sleep aid."

"Although I have fairly high blood pressure - for which I take medication, and use asthma inhalers to prevent asthma, I have found Phenergan to be absolutely marvelous for insomnia - I have an overactive mind! I find it's best to take it about four hours before I go to bed - then it knocks me out for the night. Sometimes I still feel a bit drowsy in the mornings and have discovered I only need the lowest dose to get a good night's sleep. I only take it the night following a sleepless night. Hope this is helpful."

"I took 3x 25mg Phenergan to help me sleep. The next morning, I woke up covered in bumps & bruises. Apparently, I had a grand mal seizure during the night. I haven't had a seizure in 9 years. The chemist failed to tell me that this drug can bring on seizures. I just want other people to know about this as I was unaware... Thanks."

"I have no problem falling asleep, but wake in the night and sometimes cannot fall back to sleep. I take one half tablet 12.5 mg of Phenergan and even if my sleep is disturbed, I fall back to sleep easily and wake up refreshed."

"Has anyone had weight gain with Phenergan 25mg? I've put on 5 kilos quickly since using this & another drug, Valdoxen. Valdoxen helps with your melatonin receptors, is also an antidepressant, & says you do not put weight on. Not sure which one it is! Phenergan does say it can cause weight gain, especially in females, but they are not sure why. Though they state it's thought it can make you hungry thus you eat more. This isn't the case for me. I've been eating & exercising normally so something is going on. It's fabulous for sleep though, I finally get a great sleep. Confused!!"

"I only take 6 mg (1/4 of a 25 mg tablet) at night before I have to work the next day, i.e., Sun to Thurs night. The first time I took a whole pill, never again as it knocked me out, but the next morning I had to stay home as I was so drowsy! I prefer this to taking Lorazepam."

"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."

"This medicine helped sedate me when I was having back pain. I had two herniated discs, and it calmed me down before and after the surgeries. It is not habit-forming and was a plus with all the other medicines I was on."

"Took one 25mg to help me sleep, however, the next day I felt awful. Like I'd been drugged, just couldn't wake up. This lasted all day. I won't be taking them again. My wife, on the other hand, takes them every night with no problems."

"I got these over 4-5 months. I started with 25 mg and ended up taking 2 every evening before bed. I started getting restless legs to the point where I had to wander around in my flat for hours like a zombie, and I sometimes only got a few hours of sleep. Also, I began to get a bloody nose. Every morning I had to clean my nose with tissues, and the paper was always bloody. And the weight gain. I gained 15 kilos in that time. Right before I quit taking them, I was miserable. Almost every night I had restless legs, and I didn’t get much sleep. I have been off Phenergan since the beginning of August - I lost 7.6 kilos, my nose is just fine, and I haven’t had one second with restless legs since. I’m back to having trouble falling asleep, but I definitely prefer that to all the horrible side effects."

"Phenergan is the best sedation I have seen... I find over 12.5 mg knocks me for 'six.' Most of these medications are best when used sparingly, when needed. Taking sedation every night tells me a powerful antipsychotic may be a more suitable option."

"I don't know if I classify myself as an insomniac, but I usually wake up a lot of times in the night, which disturbs my sleep and makes me tired in the day, so I decided to try Phenergan. This medication should really be taken just before you go to bed, I wouldn't recommend taking it while you're watching TV or anything because, in my experience, you have to be trying to fall asleep for this to work. Even then, it's a horrible drug. 25 mg is too little, and I still wake up in the night a lot, 50 mg is way too much, and I'm pretty sure my throat closed up for a second in the middle of the night because I woke up gagging, and I don't suffer from sleep apnea, so that was weird. Either way, any dosage of this stuff causes terrible daytime drowsiness the next day, I'm not sure if that's down to the half-life of the medication or whether it is purely because it gives you really poor quality sleep."

"I have restarted taking 3 months ago, after coming off amitriptyline cold turkey. These are more suited as you can take most cold and flu medication without issues, which was always an issue. The tablets take effect quickly (1.5 hours). I first started on 50 mg per night, now down to 30 mg due to tablets now making me more sleepy during the daytime than before. I would recommend these to any anxiety or insomnia sufferer as they do not have neuro side effects like other sleepers."

"I have been taking these for almost 5 years, what started as 1 x 10 mg then turned into a huge dose. I have now dropped down to 3 x 10 mg a night and have decided it’s time to go completely cold turkey off them. I started taking these to sleep easier, as due to anxiety it was hard to fall asleep. I have made the decision to come off them, as I was getting intense nightmares which made me afraid to fall asleep, my body was bruising extremely easily, and my platelets were beginning to drop. Just be careful if you have an addictive personality."

"After experiencing a severe onset of anxiety, I developed insomnia and couldn't sleep for over three weeks, remaining awake throughout the night. Additionally, I woke up with nausea and vomited for some days. I was prescribed 25 mg to take before bed to help with sleep and nausea. The first time I took it, I slept for 12 hours! I felt drowsy the next morning but also refreshed and didn't wake up with nausea. The second time I took it, I slept for 8 hours and was still a little drowsy. Taking 25 mg before bed definitely helps sedate me and improves my sleep throughout the night."

"I have really bad insomnia. I cannot get to sleep at all. I take 50 mg of Phenergan. And it takes a while to work, like 4 hours, then I fall asleep. I have tried other meds, and they work for a short time, but it is slow to work, so that I lay in bed for at least 4 hours until I fall asleep, but at least it works."

"Take 50 mg at night to help me sleep, as it takes away the anxiety. It works a treat. I'm very sedated and calm after 1 hour and can sleep 8 hours. Only downside, I seem to crave sugary foods like chocolate, so I tend to binge (can eat a whole entire packet of biscuits in 10 mins)."

"I have recently started taking Phenergan, I take two 50 mg tablets about 20 minutes before sleep. 9 times out of 10, I'm having the most intense nightmares! I've literally just woken up from another. These tablets do work, however, you need to be mindful that nightmares can occur."

"Taken to help me sleep, didn't really feel it worked as still awake at 1 AM (took it at 8 PM). The next morning, I couldn’t wake up. I was tired all the next day, dry mouth, and was exhausted. Had to stay home as I could barely open my eyes. Won’t be taking it again."
