Final treatment plans are shared decisions determined with your clinician after this online assessment. Always read the leaflet and treatment plan.

Who is it for?

Promethazine is suitable for people that can't fall asleep, that wake up during sleep and suffer from insomnia. We typically recommend it for those that need an on demand solution occassionly throughout the month. An example being someone that might have had a really stressful day at work and need help that night to drop off, a shift worker that has irregular sleeping patterns or someone that may be suffering with occasional night time discomfort that keeps them up.

How to take it?

Take one tablet 30 mins before bed.

Are there any side effects?

Promethazine is not addictive and side effects are usually rare and mild. Common side effects include feeling sleepy, nightmares and feeling dizzy or confused.

Been using Good nights now for approx three months and it has significantly improved the quality of my sleep. I sleep longer and deeper when I have had a tablet. Very much recommend.

Promethazine: Everything you need to know
Curated by Dr. Earim Chaudry, Manual Medical Director
Overview

Promethazine is a drowsy antihistamine that is medically proven to help with insomnia. Unlike traditional sleeping tablets (Z-drugs), Promethazine is effective without being addictive. It works by preventing the release of histamine, a compound that wakes you up.

Are there any side effects?

Promethazine is not addictive, and side effects are usually mild. Common side effects include feeling sleepy, nightmares and feeling dizzy or confused. Do not drive or use machinery for four to five hours after taking Phenergan (Promethazine), or if you feel sleepy.

How do I take Promethazine?

Take one tablet 30 mins before bedtime and do not combine with alcohol. We recommend pairing it with Good Nights, our natural supplement that contributes to the reduction of tiredness and fatigue.
