Avomine tablets contain promethazine which belongs to a group of medicines called phenothiazines. Avomine is an anti-emetic (anti-sickness drug) which helps to prevent, and treat nausea and vomiting, including travel sickness, and vertigo.
Preventing travel sickness
The usual dose for adults is:
- Long journeys: take one tablet each night at bedtime starting the night before you travel.
- Short journeys: take one tablet one or two hours before travelling.
Treatment of travel sickness
Take one tablet as soon as you feel sick followed by a second tablet the same evening. Take a third tablet the next evening if necessary.
Nausea and vomiting due to other causes
One tablet each night is usually enough, but two or three tablets may be required by some patients. These can be taken at intervals during the day, but it is often not necessary for more than 4 tablets to be needed in any 24 hour period.

Like all medicines Avomine can cause side effects, although not everybody gets them. If you experience any of the following side effects speak to your doctor immediately:
