Colofac (Mebeverine Hydrochloride) – Patient Information

Colofac is a medicine used to help relieve the symptoms of irritable bowel syndrome (IBS), particularly bowel spasms and cramp-like pain. It contains mebeverine hydrochloride, an antispasmodic medicine that works directly on the gut to reduce spasm-related discomfort.

This page explains how Colofac works, how to take it, what to expect, and important safety information. If you have any questions, speak to a pharmacist or clinician.

Key facts at a glance

• Active ingredient: Mebeverine hydrochloride
• Common use: Symptoms of IBS (spasms, cramps, abdominal discomfort)
• How it works: Helps relax bowel muscle spasms without broadly affecting normal bowel function
• Typical form: Tablets/capsules (brand presentation may vary by pack)
• UK availability: Sold through UK pharmacies; suitable for many people with IBS symptoms

What is IBS and what does Colofac help with?

IBS is a common gut–brain condition that can cause symptoms such as:

• Crampy abdominal pain
• Bloating and discomfort
• Changes in bowel habit (constipation, diarrhoea, or mixed)
• Urgency or a feeling of incomplete emptying

Colofac is used to relieve symptoms caused by bowel spasm. It is not a cure for IBS, but it can help many people manage day-to-day symptoms.

Mechanism of action (how it works)

Mebeverine works as a direct-acting smooth muscle antispasmodic in the intestine. In simplified terms, it:

• Reduces abnormal contractions (spasm) of the bowel muscle
• Helps normalise intestinal motility so the gut can move more comfortably
• Targets the muscle in the gut wall rather than causing widespread sedation or general pain relief

Because it mainly addresses spasm-related symptoms, some people find it particularly helpful for cramping and pain that comes and goes.

Pharmacokinetics (absorption, distribution, metabolism, elimination)

Pharmacokinetics describe what the body does to the medicine. While exact details can vary between individuals, the general pattern for mebeverine is:

• Absorption: After oral use, mebeverine is absorbed from the gastrointestinal tract.
• Metabolism: The medicine is largely metabolised in the body (it is broken down into metabolites).
• Excretion: Metabolites are then eliminated, mainly via urine.
• Duration of effect: Dosing is designed to maintain symptom relief over the course of the day.

If you have liver or kidney problems, it is sensible to discuss this with a pharmacist, as they may advise how best to manage your treatment.

Typical uses (indications)

Colofac is indicated for the symptomatic treatment of irritable bowel syndrome where bowel spasm contributes to:

• Abdominal pain
• Cramping
• Discomfort related to intestinal spasm

It is often chosen when symptoms are intermittent and appear linked to gut muscle contractions.

How and when to take Colofac

General dosing principles

Always follow the instructions provided with your pack or by your clinician/pharmacist. Dosage may depend on age and the specific strength/formulation.

Common adult use: Typically taken two or three times daily, depending on the product strength and formulation. For many IBS patients, regular dosing for the first few days helps assess response.

If you miss a dose: Take it when you remember, unless it is close to the next dose. Do not take a double dose to make up for a missed one.

Timing (with or without food)

• Colofac can usually be taken with or without food.
• Many people find it easiest to take alongside meals to maintain routine.

Consistency is important in IBS management, as symptoms can fluctuate.

Dosing information (overview)

The table below summarises typical adult dosing schedules commonly used for mebeverine products. Because pack strengths vary, check your specific carton/blister instructions for exact directions.

Food interactions

There are no well-known major food interactions for mebeverine, and it is generally regarded as suitable to take either with or without food.

However, IBS is strongly influenced by diet and gut sensitivity. You may find that:

• Taking Colofac consistently helps you distinguish medicine effects from dietary triggers
• Large, fatty meals or foods that trigger your symptoms may still cause discomfort even if you are taking an antispasmodic

If your symptoms worsen after specific meals, consider keeping a short diary of triggers and discuss options with a pharmacist or clinician.

Alcohol interactions

There is no commonly reported direct interaction between mebeverine and alcohol. That said, alcohol can worsen IBS symptoms in some people by affecting gut motility, increasing sensitivity, or triggering diarrhoea.

Practical advice:

• If you choose to drink alcohol, start with a small amount to see how you react.
• Be cautious if you notice cramping, urgency, or worsening pain after alcohol.

Medicine interactions

Mebeverine has a relatively low risk of clinically significant drug interactions. However, as with all medicines, it is important to consider your entire medication list.

Before starting Colofac, tell a pharmacist if you take any of the following:

• Other gut-related medicines (for IBS, diarrhoea, constipation, or antacids)
• Medicines for pain relief (especially if they upset your stomach)
• Medicines that may affect bowel habits
• Any herbal supplements or remedies

If you are pregnant, breastfeeding, or have significant medical conditions, get tailored advice before using any medicine.

Safety profile and side effects

Most people tolerate Colofac well. Like all medicines, it can cause side effects, though not everybody gets them.

Common side effects

Common side effects are typically mild and may include:

• Headache
• Dizziness
• Nausea

Less common or serious reactions (seek advice urgently if needed)

Stop the medicine and seek urgent medical advice if you develop signs of a serious allergic reaction, such as:

• Swelling of the face, lips, tongue, or throat
• Difficulty breathing or wheezing
• Severe rash, blistering, or widespread hives

When to speak to a clinician urgently

While IBS is common, certain symptoms may indicate a different condition. Get medical advice promptly if you have:

• Unexplained weight loss
• Blood in your stool or black/tarry stools
• Persistent vomiting
• Fever
• Symptoms that begin suddenly at an older age
• New symptoms that steadily worsen despite treatment

Practical use tips for getting the best results

IBS symptoms often fluctuate, so a few practical steps can improve the chance of success with treatment:

• Start consistently: Try taking Colofac regularly for a short period (for example, several days) to assess benefit.
• Track your pattern: Note when pain/cramping starts, what you eat beforehand, stress levels, and bowel changes.
• Pair medicine with lifestyle changes: Consider dietary adjustments such as reducing known triggers (common ones include high-fat meals, certain sweeteners, and caffeine) and increasing fibre gradually if constipation is an issue.
• Hydrate: Adequate fluid intake can help bowel function and reduce discomfort.
• Manage stress: The gut–brain connection can make stress a powerful trigger.
• Know when to reassess: If you see no improvement after trying for the recommended period on the pack, speak to a pharmacist about other options.

What to expect (timing of symptom relief)

People often report symptom improvement after starting antispasmodic treatment, but the timing can vary:

• Some notice relief within hours to days, especially when the main symptom is cramping.
• For others, it may take several days of consistent dosing to judge effectiveness.

If your symptoms are severe or you experience any concerning features (e.g., bleeding, weight loss), seek medical advice promptly rather than continuing self-management alone.

Alternative options for IBS symptoms

IBS management in the UK may involve lifestyle adjustments, dietary strategies, and different medicines depending on your dominant symptoms (pain/spasm, diarrhoea, constipation, bloating). Options your pharmacist or clinician may discuss include:

For cramping and pain

• Other antispasmodics (choice depends on availability and suitability)
• Muscle-relaxant/antispasmodic approaches tailored to your symptoms

For diarrhoea-predominant IBS

• Loperamide (for short-term control of diarrhoea)
• Medicines targeting gut fluid secretion or motility (availability varies)

For constipation-predominant IBS

• Osmotic laxatives (where appropriate)
• Fibre supplements or stool softening strategies (gradual introduction is often best)

For bloating

• Dietary adjustments (for example, identifying triggers)
• Carminatives or other therapies depending on local availability

Because IBS symptoms overlap, the “best” option depends on what bothers you most. Colofac is generally chosen for spasm-related pain and discomfort.

UK market and legal context (availability and classification)

In the United Kingdom, medicines are regulated and categorised under the Medicines and Healthcare products Regulatory Agency (MHRA) framework. Products may be supplied through different routes depending on safety considerations and licensing status.

Colofac is commonly supplied for IBS symptom relief through UK pharmacy channels. Availability can vary by presentation and strength, and retailers may provide counselling based on the product’s classification.

If you are uncertain whether Colofac is the right choice for your situation, a pharmacist can help you review symptoms, suitability, and how to use it safely.

Recent guidance and care approach in the UK

UK healthcare guidance for IBS typically emphasises a stepwise approach:
