Colofac is a medication used in the treatment of irritable bowel syndrome (IBS). It contains the active ingredient mebeverine hydrochloride, which works by relaxing the muscles in and around the gut. This helps to relieve spasming symptoms caused by IBS. It is a well-tolerated medication that is used extensively in the treatment of patients with IBS. 

It is available as both normal release tablets or modified-release tablets (Colofac MR).

Colofac Dosing

You can take up to 1 tablet 3 times a day. It may be more effective if taken around 20 minutes before a meal. The reason for this is that some people find their symptoms are worse after food.

Colofac MR capsules have a different dose. One capsule can be taken twice a day because the tablets stay in your system longer.

You should always take the medicine exactly as the doctor has told you to.
