Dosage and how to take peppermint oil
Dosage
The usual dose of peppermint oil capsules, for adults and children aged 12 years and over, is 1 capsule, taken 3 times a day until your symptoms get better.
You can increase this to 2 capsules, taken 3 times a day, if 1 capsule does not help your symptoms.
How to take peppermint oil capsules
It's best to take peppermint oil capsules around 30 to 60 minutes before food (which can be a meal or snack).
Swallow the capsules whole, with water. Do not break or chew them.
Leave a gap of at least 2 hours between taking a dose of peppermint oil and taking an indigestion medicine. This allows the peppermint oil capsules to work properly.
