I just learned about Phenergan through this site and am intrigued. I have been to the ER more times than I can remember for vomiting and no doctor ever mentioned this drug. Even though it sounds sedating I would rather be asleep at home rather than vomiting and dehydrated in the ER. Has anyone suffered serious side effects from taking it? If they give it to pregnant women how bad can it be? Zofran doesn’t work for me.
