For Nausea/Vomiting "Had an outpatient procedure and put into a 'twilight sedation,' with additional pain meds through the IV, although I can’t recall what that was. The pain meds caused me terrible nausea and dizziness. I was given a dose of Zofran and a motion sickness patch before surgery to try and prevent this, as I get nauseous from pain meds so easily... that didn’t work. I was given 12.5 mg of Phenergan, and 15 minutes later, symptoms had improved greatly. I was able to get dressed and start on my way home, although the nausea was still present somewhat due to the motion of the car ride home. Hit the bed and slept like a rock for four hours, felt sleepy the rest of the evening. Blood pressure did go up some as well, 132/88. Took my usual beta blocker at bedtime that helped my BP come down."

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 Nausea/Vomiting "Second trimester of pregnancy and had lost 30 lbs due to hyperemesis. None of the other nausea meds were working, they even gave me suppositories. I was admitted to the hospital, and I ended up on an IV drip of Zofran for a couple of days to give me some relief. Once they took me off the drip, I was scheduled to get the Zofran regularly. One particular nurse was terrible about giving me my medication on time, and I got so sick they had to look for an alternative. She gave me Phenergan, which made me drowsy, uncoordinated, disoriented, and gave me restless leg for a while. That experience was terrifying. When the doctors came in to check on me, they told me that I was given too big of a dose, so they were going to try it again at half a dose. That half dose was AMAZING!!! It took away the nausea immediately and allowed me to sleep comfortably. That became my regular nausea med for the rest of the hyperemesis, and I was given a prescription to use at home as needed. It saved my life."

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 Sedation "Hated it. Sure enough, I slept straight through for 8 hours, but I experienced attacks of vertigo for 2 days afterwards. Never again."
