For Nausea/Vomiting "I have Cyclic Vomiting Syndrome. Believe me, I tried EVERYTHING for my nausea. Zofran, Omeprazole, Dramamine, etc. You name it, I've tried it. Nothing could stop my violent vomiting episodes. Phenergan suppositories are the only thing that could ever put a stop to my nausea and vomiting. The only problem is, it makes me very, very tired, so I can hardly function in classes if I have to take it during the day. But I'll take being a little 'out of it' over being so sick any day!"

For Nausea/Vomiting "Woke up with dizziness and terrible nausea. After 5 hours of dry heaving, went to doctor. One injection and nausea gone almost immediately. Slept for 3 hours, then ate dry bagel, chicken soup without any problems. Next day, eating normally but feel tired and a little 'under the weather'."

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 Nausea/Vomiting "I use Phenergan for nausea. I take 25 mg to 50 mg. More effective than Zofran, which doesn’t work on me. It causes a bit of tiredness, but not the putting me to sleep type—just relaxes me, which is appreciated when I have nausea."

For Light Sedation "I took the recommended dose and was extremely drowsy, yet angry and restless. It was like I wanted to scream out of frustration, but was too tired and edgy."

For Nausea/Vomiting "This medicine helped my nausea, but made me too tired to function properly. It would be great if you have nausea at nighttime."
