I’ve been given phenergan IV in a hospital setting, and it provides profound sedation, and a wonderful anti-anxiety effect. I also have prescriptions for phenergan at home via oral and IM route, in which I get none of these effects. In fact, via oral route it doesn’t seem I’ve taken the drug at all. Via IM, it just burns and I don’t get any beneficial effect. What’s the difference between getting phenergan in the hospital setting vs at home, and where should I inject the phenergan at home to get the sedation, relaxing effect ? Thanks.
