Colofac (Mebeverine Hydrochloride) – Patient Information

Colofac contains mebeverine hydrochloride, an antispasmodic medicine used to help relieve symptoms of bowel spasm. It is commonly used for conditions such as irritable bowel syndrome (IBS), where the gut may feel crampy, bloated, or unpredictable.

This guide is designed to be patient-friendly and helpful when choosing and using Colofac in the United Kingdom. Always follow the dosing instructions provided with your product and speak to a healthcare professional if you are unsure.

Quick product overview

What is Colofac?

Colofac is a medicine containing mebeverine hydrochloride. It is used to relieve symptoms caused by spasms in the bowel. It does not “cure” IBS or permanently change the condition, but it may help reduce symptoms such as:

• Cramping or colicky abdominal pain
• Bowel spasms and associated discomfort
• Abdominal bloating and irregular bowel sensations in IBS

Many people find that symptoms improve when the medicine is taken regularly as advised, particularly during flare-ups.

How does Colofac work? (Mechanism of action)

Mebeverine works as an antispasmodic. Its main effect is to reduce abnormal muscle contractions in the gut wall (smooth muscle). In IBS, the bowel can become overly sensitive and may spasm. By helping to stabilise gut smooth muscle activity, Colofac can:

• Reduce the intensity and frequency of spasms
• Help relieve cramp-like abdominal pain
• Support more comfortable bowel function in some patients

Importantly, it targets spasm-related symptoms rather than directly treating an infection or inflammation.

Pharmacokinetics: how your body processes it

Pharmacokinetics describes what happens to the medicine after you take it—how it is absorbed, broken down, and cleared from the body.

• Absorption: Mebeverine is absorbed after oral dosing.
• Distribution: It acts on the gut, with effects related to its local influence on bowel muscle function.
• Metabolism: The medicine is metabolised in the body into metabolites (breakdown products).
• Excretion: Metabolites are eliminated largely via the urine and to a lesser extent through other routes.

Because the medicine is designed to act on bowel spasm activity, dosing is commonly structured to maintain symptom control over the day.

Typical uses and indications (what it is for)

In the UK, Colofac is mainly used for symptomatic treatment of irritable bowel syndrome (IBS) where bowel spasms and crampy pain are prominent.

Possible IBS-related symptoms it may help

• Spasm-associated abdominal pain
• Bowel discomfort linked to cramping
• General symptom relief in IBS (not necessarily every symptom for everyone)

If you have IBS symptoms, it’s helpful to remember that IBS can involve multiple factors—diet triggers, stress, gut sensitivity, and bowel habit changes. Colofac focuses on the spasm component.

When to take Colofac (timing and routine)

Many people take Colofac in a steady daily routine. Your leaflet or pharmacist’s instructions are the best guide for your specific product and dose.

Common timing approach

• Often taken before meals to align with gut activity after eating.
• Typically taken twice daily, spaced throughout the day.

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

Tip: If your symptoms are linked to particular meals (for example, after breakfast or dinner), consistent timing before those meals can help you notice whether the medicine is working for you.

Food interactions (what about eating?)

Food interactions: Colofac can be taken as directed and is commonly used before meals. There are no widely expected “food exclusions” for this medicine for most people.

However, IBS is often influenced by food type and portion size. Even though Colofac helps with spasms, you may still notice triggers such as:

• Large or fatty meals
• Certain carbohydrates (e.g., some people find high FODMAP foods worsen symptoms)
• Alcohol and fizzy drinks for some individuals

Practical approach: Keep taking Colofac at the advised times, and consider tracking what you eat and when symptoms occur. This can help you and your healthcare professional fine-tune your IBS management plan.

Alcohol interactions and combining with other medicines

Alcohol

There is no specific, well-known direct interaction between mebeverine and alcohol for most users. That said, alcohol can worsen IBS symptoms in some people by affecting gut motility, sensitivity, and hydration.

• If you drink alcohol, consider whether it triggers your pain, cramping, diarrhoea, or bloating.
• Moderation is sensible for overall IBS management.

Other medicines

Mebeverine has fewer common interaction concerns than some other medicines, but you should still inform a healthcare professional about:

• Any ongoing medicines (including over-the-counter products)
• Herbal remedies and supplements
• Any allergies or previous medication reactions

Seek advice if you are taking multiple medicines, especially if you have other bowel conditions or significant medical problems.

How to use Colofac: dosing guidance

Dosing can vary by age, formulation, and local prescribing/dispensing guidance. Always follow the dosage given by your product leaflet or your pharmacist.

Typical adult dosing

• Commonly taken twice daily
• Often before meals (e.g., morning and evening), depending on your routine

Children and adolescents

For children, use depends on age and the exact product strength. If the medicine is being considered for a child, check the patient information leaflet and ask a healthcare professional or pharmacist for appropriate advice.

How long should you take it?

Many people take Colofac during periods when symptoms are active. Others use it more regularly for symptom control. If your symptoms persist or worsen despite taking Colofac as directed, you should seek medical advice for review.

Safety profile: who should be careful?

Like all medicines, Colofac (mebeverine) can cause side effects, although not everyone gets them. Most people tolerate it well.

Common side effects

• Generally mild and uncommon; side effects vary person to person.

Less common or serious side effects

Stop using the medicine and seek urgent medical help if you experience signs of a serious allergic reaction, such as:

• Swelling of the face, lips, tongue, or throat
• Difficulty breathing or swallowing
• Widespread rash, hives, or severe skin reactions

When to talk to a healthcare professional promptly

Speak to a healthcare professional if you have:

• New or worsening abdominal pain
• Unexplained weight loss
• Blood in stool or black/tarry stools
• Fever, persistent vomiting, or severe dehydration
• Symptoms that significantly change pattern, especially after age 50

These symptoms may indicate conditions other than IBS and should be assessed.

Practical use tips for best results

• Be consistent: Take Colofac at the times you’ve been advised to help maintain symptom control.
• Use alongside IBS strategies: Medicines often work best with lifestyle changes such as regular meals, adequate fluid intake, and stress management.
• Track symptoms: Note when cramps occur and what seems to trigger them (food, stress, sleep disruption).
• Consider bowel habit: If your IBS involves constipation or diarrhoea, you may need additional measures beyond an antispasmodic.
• Don’t ignore red flags: Seek prompt medical review if you notice blood in stool, unexplained weight loss, or persistent severe symptoms.

Alternative options for IBS spasm symptoms

If Colofac does not provide sufficient relief, there are other approaches commonly used for IBS symptom management. Alternatives may include medicines and non-medicine treatments.

Medication options (examples)

• Other antispasmodics: Some medicines in this class may be used depending on symptoms and availability.
• Osmotic laxatives (if constipation is a major feature): to help stool consistency and ease.
• Anti-diarrhoeal treatments (if diarrhoea is a major feature): to reduce stool frequency and urgency.
• IBS-targeted options (for specific symptom patterns): your pharmacist or clinician can advise based on your IBS subtype.

Non-medicine options

• Dietary changes: such as reducing known triggers or considering a structured low-FODMAP approach.
• Fibre adjustments: soluble fibre may help some people (always consider individual tolerance).
• Probiotics: evidence varies; some people benefit, others do not.
• Psychological therapies: options like cognitive behavioural therapy can help gut–brain interaction.

The best choice depends on your symptoms (pain only versus pain plus diarrhoea/constipation), severity, and how you respond to treatment.

UK market and legal context (what this means in practice)

In the UK, medicines are regulated to ensure quality, safety, and appropriate use. How you obtain Colofac may depend on its legal classification (for example, certain medicines may be sold via pharmacies under specific conditions).

Online pharmacies in the UK should:

• Provide clear product information and dosing instructions
• Offer appropriate customer checks where required by UK regulations
• Ensure you receive a genuine product in authorised packaging

If you’re shopping online, choose a reputable UK-registered pharmacy and confirm delivery options and return policies before ordering.

Recent guidance and best-practice approach

In the UK, IBS management typically follows a stepwise approach. In general terms, healthcare advice often emphasises:

• Confirming that symptoms are consistent with IBS and not another condition
• Providing lifestyle and dietary guidance
• Using targeted medicines based on symptom pattern (pain, diarrhoea, constipation)
• Reviewing treatment if symptoms persist or change

Colofac fits into this approach by addressing spasm-related pain.

Delivery and availability in the United Kingdom

Colofac may be available through:

• High-street pharmacies
• Online pharmacies that deliver across the UK (within applicable regulations)

Delivery speed and costs vary by retailer. Common options include standard and express delivery where offered. Always check:

• Estimated delivery date at checkout
• Packaging and dispatch times
• Availability of your preferred pack size
• Customer support and contact details

Keep the medicine in its original packaging and store according to the leaflet’s temperature and storage instructions (commonly “store below 25°C” unless stated otherwise on your specific pack).
