Always follow your doctor's instructions about how and when to take your medicine.
Dosage and strength
Betahistine comes as 8mg or 16mg tablets.
The usual starting dose is 16mg, taken 3 times a day.
Leave 6 to 8 hours between doses.
When your symptoms are under control, your doctor may reduce your dose to 8mg, taken 3 times a day.
How to take it
Swallow the tablet whole with a drink of water.
It's a good idea to take your betahistine tablets after a meal. It will be less likely to upset your stomach.
How long to take it for
You may need to take betahistine for a long time, such as several months or years, to prevent the symptoms of Ménière's disease.
If you forget to take it
If you forget to take a dose of betahistine skip the missed dose and take your next dose at the usual time.
Do not take 2 doses at the same time. Never take an extra dose to make up for a forgotten one.
If you often forget doses, it may help to set an alarm to remind you. You could also ask a pharmacist for advice on other ways to help you remember to take your medicine.
If you take too much
Taking too much betahistine can make you feel sick or sleepy, or give you stomach ache.
