For Sedation "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!"

For Sedation "I have suffered with insomnia for years, mostly because of racing thoughts that I find hard to control. So, need to take a sedative about 3 times a week for sleep to function. I've been on prescription-strength sleeping pills in the past, but doctors are very reluctant to prescribe, which is no surprise given the side effects and high addiction risk. So, I take Phenergan/promethazine. I find after an hour I get sleepy, gives me a mellow feeling, and it seems to switch off my thoughts, making it easier to fall asleep. I do wake up tired on this drug because it is a sedative and have a dry mouth, but after a strong coffee and shower, I am back to normal and feel refreshed, like I had a good sleep on this drug. Other than a dry mouth, I find it a good medication with little to no side effects."

For Urticaria "Chronic hives - 25 mg works well after desloratadine ceased working for me. Side effects of sedation, lethargy, falling asleep very quickly (sometimes inappropriately), dry eyes and mouth. (If I was working and not retired, the side effects may not have been manageable)"

For Sedation "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."
