How to take Promethazine

Depending on what you are using Promethazine for, the dosage will vary. You may also vary your dose depending on the response, but this should be done according to the patient information leaflet, or on your doctor's advice. 

Below is a summary of the most common uses of Promethazine and the corresponding dosages.

Insomnia
When taken for insomnia, the usual dose of Promethazine is 25mg taken once daily at night. You should take this around one hour before bedtime. Promethazine is intended for short term use only when treating insomnia, so if your symptoms go on for longer than 3 nights, see your GP.

Hay Fever
Those taking Promethazine for hayfever generally use the 10mg tablet, and this is taken 2-3 times daily depending on symptom control. Many hayfever sufferers prefer non-drowsy anti-histamines however, as these are less likely to impact your alertness during the day. These include cetirizine and loratadine.

Travel Sickness
The dosage of Promethazine, when used to prevent travel sickness, is generally one 25mg tablet taken about 60 minutes before travel. This gives the drug enough time to be absorbed into your system and get to work! Promethazine can be very effective in reducing nausea felt in those travelling by land, air or sea.
