For Nausea/Vomiting "I was prescribed Phenergan after having my wisdom teeth removed. When I got home, I immediately fell asleep (still under the influence of the anesthesia). Upon waking and attempting to stand, I began to heave and vomit profusely, but after laying back down and taking Phenergan, my symptoms were gone nearly instantly. Would definitely recommend; Phenergan was an important part of my recovery!"

For Nausea/Vomiting "I had gallbladder surgery and got narcotics for pain afterwards. No matter what painkiller I got, they made me vomit even at half the dose. Ondansetron (Zofran) helped some but not fully. Once I got my first dose of Phenergan, my nausea was completely gone. It made me very sleepy, but I was very happy about it. This was the best anti-nausea medication that I ever had!"

For Nausea/Vomiting "I suffered from Cyclic Vomiting Syndrome; similar to an abdominal migraine. The gastroenterologist prescribed Phenergan suppositories as a prophylaxis. It prevented the onset of the nausea and vomiting. Just knowing it is in my refrigerator should I need it has stopped the cycle."

For Nausea/Vomiting "I had a very serious vomiting problem with my first pregnancy. I had to be hospitalized and then put on an IV at home for fluids. When I was about two months pregnant with my second child, I was given promethazine, and it was the only thing that kept me from the same issues as the first pregnancy. I was still sick every day, and I was still vomiting sporadically. However, I was able to actually eat and drink and gain weight. My son was born fine. Now I am pregnant with my third and have started on it earlier than the second pregnancy. I was not aware that the effects of the drug on unborn children are unknown. My doctor had told me it was safe. Hopefully, this next baby will be fine as well."

For Opiate Adjunct "I have been taking Phenergan 25 mg for years now. I have no problem with it, and it works fine for me. This is for the lady that said she was 65 years old and her daughter had the same reaction. You are severely allergic to Phenergan, do not take it anymore, please. My wife was prescribed it for nausea and vomiting. She started taking it, and every time she started feeling like throwing up, by the time I made her go to the emergency room, she was on the couch with her feet raised. I mean, I had to put a cinder block under the end of the couch to raise it up enough for her. She could not stand up without throwing up, and I had to hold her up to get to the bathroom. She was in the hospital for a week. Now she cannot look up without getting dizzy and going to pass out!"

For Nausea/Vomiting "As a type 1 diabetic, I occasionally get nausea and/or vomiting with low blood sugar. If blood sugar levels are severely low, you may feel nausea and something similar to a migraine headache, in my case, with locking-tight neck muscles. It is hard to get blood sugar levels up when you are vomiting. I have found a Phenergan suppository is the only thing that works for me during these episodes. It works very quickly to stop nausea and gives me enough time to eat before making me sleepy. I have been diabetic for more than 40 years, so it is not as though I am inexperienced, and I have both an insulin pump and blood testing equipment with which to check my glucose levels before I ever consider going to sleep. I do not recall ever being truly 'knocked out' long term, but asleep for a few hours, long enough for the headache and tight neck muscles to subside."

For Nausea/Vomiting "I've been taking this medication for a minimum of 15 years. It is a very good medication. I use it for nausea and vomiting. It does the trick. It also aids with my pain & insomnia, only when combined with other meds. But, even though I'm well educated on Phenergan, if I take it too frequently, it gets built up in my system and gives me severe restless leg symptoms! If you've never had it - avoid it! Just take it only when necessary."
