Take 1 tablet up to three times a day, ideally around 20 minutes before your usual main meals. Swallow each tablet with plenty of water – do not chew them.

If you miss a dose, take it as soon as you remember, but skip it if it's almost time for your next dose; do not double up on doses. Continue taking alverine as prescribed, even if you start feeling better, and do not stop without consulting your doctor.

Unless you have been specifically advised by your doctor, only take this medicine when needed. This means that you should only take it once your symptoms begin to flare up and stop taking it when they subside. This can take a couple of weeks.

If your symptoms have not improved after two weeks, or if they get worse, you should stop using this medicine and contact your doctor.

Always use this medication exactly as your clinician has told you. Check with our clinical team or your GP or pharmacist if you are not sure.
