I was prescribed Promethazine 50mg Suppositories for severe nausea and vomiting during a recent bout of illness. The doctor explained that it works by blocking certain natural substances in your body that cause these symptoms. It did help, but I want to share my experience and discuss the potential side effects and risks of this medication. I'm curious about how others have experienced this treatment, and if anyone has insights on managing the side effects. Has anyone else used this for allergic reactions or to calm down before a procedure? What were your experiences like? The possible side effects are quite concerning, and I'm worried about the risk of severe reactions.

What do you do if you experience confusion or altered mental state? Is that a common side effect or do those symptoms indicate something more serious?

This drug can be a lifesaver for severe nausea, but the side effects are no joke. I've heard of people experiencing neurological symptoms and abnormal heart rhythms. If you're taking this, make sure to stay in close contact with your doctor and report any unusual symptoms immediately.

Promethazine really helps with my sickness, but can it cause you to faint or something? What kind of changes in eyesight are common?

I used Promethazine for allergies and it helped me a lot. I didn't experience any severe side effects, just a bit of drowsiness and dry mouth. But I'm glad to know about the potential for serious reactions now.

You need to be careful with this medication. I've seen people experience severe breathing problems and abnormal heart rhythms. If you experience any of these symptoms, contact your doctor or seek medical attention immediately.

If you experience any signs of an allergic reaction, such as rash, hives, or trouble breathing, seek medical attention immediately. Don't wait to see if it gets better.

I was given Promethazine suppositories before a procedure and it helped me stay calm. No side effects but I was monitored constantly.
