How to take Phenergan
Depending on what you are using Phenergan 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 Phenergan and the corresponding dosages.
When taken for Insomnia, the usual dose of Phenergan is 25mg taken ONCE daily at NIGHT. You should take this around one hour before bedtime. Phenergan is intended for short term use only when treating insomnia, so if your symptoms go on for longer than 3 nights, see your GP.
Those taking Phenergan 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.
The dosage of Phenergan, 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.
