Campral (Acamprosate) – Patient Guide (UK)

Campral contains acamprosate, a medicine used to help maintain abstinence in people who have stopped drinking alcohol. This guide explains how it works, how to take it safely, what to expect, and key interactions—written in clear, patient-friendly language for the United Kingdom.

Basic product information

Campral is an established medicine in the UK for helping people who have successfully stopped drinking alcohol to stay abstinent. It is used alongside broader alcohol support, such as counselling or addiction services.

When considering any treatment for alcohol dependence, it’s important to involve healthcare professionals—especially if you have other medical conditions (particularly kidney problems) or take multiple medicines.

How Campral works (mechanism of action)

Long-term heavy alcohol use can change how certain chemical messengers work in the brain. After stopping alcohol, some people experience persistent cravings and a feeling of imbalance in brain activity, which can make relapse more likely.

Acamprosate is thought to help by modulating neurotransmission—particularly systems involving glutamate and GABA (brain signalling pathways linked with reward, stress responses, and excitability). In simple terms, it helps the brain rebalance after alcohol withdrawal, reducing the pull toward drinking and supporting long-term abstinence.

Important: Campral is not designed to treat acute alcohol withdrawal symptoms (such as shaking, sweating, or severe agitation). It supports maintaining abstinence over time.

Pharmacokinetics (how the body handles it)

Pharmacokinetics describes what happens to a medicine once you take it—absorption, distribution, metabolism, and elimination.

• Absorption: Acamprosate is absorbed after oral dosing, with levels reaching peak concentration within a few hours.
• Distribution: It spreads through the body and may distribute into relevant tissues, including the central nervous system.
• Metabolism: It is not extensively metabolised by the liver.
• Elimination: The medicine is primarily eliminated via the kidneys (renal excretion).

Why this matters: Because Campral is mainly cleared by the kidneys, dose adjustments and extra caution may be needed in people with reduced kidney function.

Typical use in the UK

In the UK, Campral is used to help people maintain alcohol abstinence after they have stopped drinking. It is commonly used as part of a wider plan that may include:

• Support from a GP or specialist addiction service
• Psychosocial interventions (for example, counselling, relapse-prevention programmes)
• Monitoring and follow-up to improve adherence
• Addressing related issues such as anxiety, depression, sleep problems, or housing/finance stress

Indications (who Campral is for)

Campral is indicated for:

• Maintenance of abstinence in adults who have already stopped drinking alcohol.

It should not be used as a standalone solution for severe alcohol withdrawal. If you are currently withdrawing from alcohol or have severe symptoms, urgent medical assessment is needed.

When to start and timing

Campral is generally started when a person has already stopped drinking. The exact timing should follow your individual treatment plan.

• Best time to start: After achieving abstinence and when it is medically appropriate.
• Consistency matters: Taking the medicine at the right intervals helps maintain steady effect.
• How soon you feel it: Some people notice changes over weeks; it is typically used for ongoing maintenance rather than immediate effects.

Dosing (typical adult regimen)

Dosing can vary based on age, kidney function, and clinical judgement. Below is the typical adult regimen used in many settings. Always follow the instructions provided by your clinician and the product information leaflet.

How to take:

• Take tablets regularly across the day (commonly morning, afternoon, and evening).
• Try to keep roughly even intervals between doses.
• If you miss a dose, take it when you remember unless it is close to the next dose—do not double up.

Food interactions and taking with meals

Food effects: Acamprosate can be taken with or without food for most people. However, maintaining a routine (for example, taking doses after meals) can support adherence and reduce stomach upset in some individuals.

Practical suggestion: If you find it easier, take doses with meals or consistently at similar times each day. If you have any digestive concerns, talk to your pharmacist.

Alcohol and medicine interactions

Campral’s purpose is to support abstinence. Therefore, continuing to drink alcohol can reduce the usefulness of the treatment and may worsen your overall health.

Can you take Campral if you drink occasionally?
Ideally, no. Campral is intended for maintenance of abstinence—your outcome is generally better when you do not drink.

Interaction with other medicines:

• Acamprosate has minimal metabolism in the liver, so it is generally considered to have fewer drug-drug interactions than some other alcohol-dependence medicines.
• However, individual risk depends on your overall medication list, kidney function, and other conditions.

Tell your pharmacist or GP about all medicines you take, including:

• Over-the-counter products (including cough/cold remedies)
• Herbal products and supplements
• Other treatments for alcohol dependence (if applicable)
• Any medicines that affect the kidneys

Safety profile and common side effects

Like all medicines, Campral can cause side effects. Many people tolerate it well, especially when doses are appropriate for kidney function.

Common side effects

• Diarrhoea (one of the more frequently reported effects)
• Nausea
• Abdominal discomfort
• Headache
• Dizziness
• Fatigue

Serious side effects (seek medical advice urgently)

Serious reactions are uncommon. Contact urgent medical services or seek urgent advice if you develop:

• Signs of a severe allergic reaction (for example, swelling of the face/lips, difficulty breathing, widespread rash)
• Severe persistent diarrhoea or signs of dehydration (such as marked weakness, fainting, very reduced urination)
• Any symptoms suggesting kidney problems, especially if you already have kidney disease

Who needs extra caution

• People with kidney disease: dosing may need adjustment and monitoring may be required.
• People with severe medical conditions: overall risk-benefit should be reviewed.
• Pregnancy and breastfeeding: discuss with a healthcare professional to weigh benefits and risks.

Practical use tips (to help you succeed)

Campral can only work well if it’s taken consistently and supported by an overall recovery plan. The following practical tips may help:

• Set reminders: Use a phone alarm, pill organiser, or calendar prompts for three-times-daily dosing.
• Plan ahead: If your routine changes (work shifts, travel), make sure you can take doses on time.
• Use a pill organiser: Many people find weekly boxes with compartments helpful.
• Stay connected: Regular check-ins with a clinician or support service can improve adherence and address triggers.
• Handle missed doses calmly: If you forget, resume your normal schedule—avoid “catching up” by taking extra.
• Support abstinence: If cravings increase, use coping strategies (avoid high-risk situations, use grounding techniques, reach out to support).

Dealing with diarrhoea: If you experience diarrhoea, it may be temporary. Stay hydrated and seek advice if it is persistent or severe. Don’t stop the medicine without speaking to a healthcare professional.

Alternative options (for alcohol dependence)

Several medicines and non-medicine options may be considered depending on individual needs, health history, and preferences. Alternatives discussed in UK clinical practice may include:

• Naltrexone: helps reduce the rewarding effects of alcohol (often used when some drinking may still occur early on; clinician-dependent).
• Disulfiram: causes unpleasant effects if alcohol is consumed; requires strong motivation and supervision.
• Psychosocial interventions: cognitive behavioural therapy (CBT), relapse prevention programmes, motivational interviewing, and structured support groups.
• Withdrawal management: medically supervised detox if needed, depending on severity.

Choosing the right option: Your clinician may consider factors such as kidney/liver health, current drinking status, past treatment response, and co-existing mental health conditions.

Pharmacovigilance and UK market/legal context

Campral (acamprosate) is an established medicine available in the UK, supplied in licensed pharmaceutical packaging and subject to UK medicines regulation. In the UK, the safety and effectiveness of medicines are monitored after marketing through a national pharmacovigilance system, which encourages reporting of suspected side effects.

Medicines safety: If you think you have experienced an adverse effect, it is generally encouraged that it be reported to the relevant medicines safety reporting channels via healthcare professionals or the public reporting route described by UK health authorities.

Recent guidance and current best practice (UK)

In the UK, treatment for alcohol dependence typically follows a stepped, individualised approach. Best practice usually includes:

• Assessment of alcohol use severity and withdrawal risk
• Support for abstinence or reduction goals tailored to the person
• Combination of medicine + psychosocial interventions where appropriate
• Monitoring for adherence, side effects, and comorbidities
• Attention to kidney function for acamprosate where required

Because guidance can evolve, it’s sensible to review recommendations with your GP or local alcohol service and to follow the most up-to-date information from reputable UK health bodies.
