Effectiveness

How Phenergan Affects PatientsPromethazine is a medicine that helps to reduce pain, induce sleepiness, and treat allergies. The effects of the drug last for 4-6 hours, but may last up to 12 hours. Patients should be aware of the potential risks such as reduced alertness or breathing, increased risk of seizures, and decreased production of red blood cells.
How Phenergan works in the bodyPromethazine helps reduce allergic reactions, improve sleep, manage anxiety and tension, and reduce nausea and vomiting. It does this by blocking certain receptors in the body, including histamine H1, dopamine, alpha adrenergic, muscarinic, and NMDA receptors.

Patient Q&A Section about phenergan

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

Why does Phenergan make you sleepy?

"Promethazine blocks histamine receptors in the brain, which reduces symptoms. It also crosses the blood-brain barrier in large quantities, which can make you feel drowsy. Promethazine also blocks dopamine receptors, which prevents nausea."

Answered by AI

Is Phenergan a sedative?

"Phenergan may cause drowsiness in some people. A single dose may still affect you in the morning. Children and the elderly are especially sensitive to the effects of antihistamines."

Answered by AI

Is Phenergan good for sleep?

"Phenergan Night Time works by blocking histamine to help with insomnia and by working directly on the brain to help you feel more relaxed."

Answered by AI

What is a Phenergan used for?

"Phenergan Tablets are used as a short-term sleep aid for adults with difficulty sleeping, and to treat hay fever or hives in adults and children. They can also be used to treat nausea and vomiting, such as travel sickness."
