What is mebeverine?

Mebeverine is used to relieve the symptoms of irritable bowel syndrome (IBS) such as abdominal (tummy) pain and cramps, diarrhoea (runny poos), constipation and flatulence (farting).

Mebeverine relaxes the tummy muscles and in this way helps to ease bloating and the spasm-type pain that can occur with irritable bowel syndrome (IBS). Read more about irritable bowel syndrome

In New Zealand, mebeverine is available as tablets (135 mg).

Dose

  • The usual dose of mebeverine is 1 tablet 3 times a day. 
  • It is generally recommended that you take mebeverine only when necessary. Start taking it when your symptoms flare up and continue to take it until you feel better. Stop taking it when your symptoms settle down again (this is usually within a week or two). 
  • Always take mebeverine exactly as your doctor or pharmacist has told you. The pharmacy label on your medicine will tell you how much to take, how often to take it, and any special instructions.

How to take mebeverine

  • Mebeverine is best taken 20 minutes before a meal.
  • Swallow the tablets with a glass of water.
  • If you forget your dose, take it as soon as you remember. But, if it is nearly time for your next dose, just take the next dose at the right time. Do not take double the dose

Precautions – before taking mebeverine

  • Have you ever had problems with your bowel (such as bowel obstruction)?
  • Do you have problems with your heart such as a fast heart rate?
  • Do you have problems with your kidneys or liver?
  • Are you pregnant or breastfeeding?
  • Are you taking or using any other medicines? This includes any medicines being taken which are available to buy without a prescription, as well as herbal and complementary medicines.

If so, it’s important that you tell your doctor or pharmacist before taking mebeverine. Sometimes a medicine isn’t suitable for a person with certain conditions, or it can only be used with extra care.
