Campral (Acamprosate) – Patient Information

Campral contains the active ingredient acamprosate, a medicine used to support people who have stopped drinking alcohol. It helps reduce the likelihood of returning to drinking by supporting brain chemistry that becomes disrupted by long-term alcohol use.

This page is written to help you understand how Campral works, how it’s typically taken, what to expect, and important safety information. If you have questions about your own situation, speak to a healthcare professional.

Quick overview

Basic product information

Campral (acamprosate) is used in adults to help maintain abstinence in those with alcohol dependence who have already stopped drinking. It is often used alongside psychosocial support such as counselling or structured therapy.

In the UK, availability and local brand packaging can vary depending on supply. Your pharmacist can confirm the exact product you are receiving.

How Campral works (mechanism of action)

Alcohol dependence changes the balance of chemicals in the brain that regulate nerve signalling. Over time, this can lead to altered stress responses and cravings, making it harder to remain abstinent.

Acamprosate helps restore parts of this disrupted balance. While it does not “block” alcohol in the body like some medicines, it supports normal functioning of the brain’s signalling systems involved in alcohol-related adaptation.

• Glutamate modulation: Acamprosate influences glutamatergic neurotransmission, which is thought to play a role in alcohol withdrawal and the longer-term drive to drink again.
• GABA-related balance: It may also indirectly help normalise the balance between excitatory and inhibitory signals.

The overall goal is to reduce the risk of relapse and help support sustained abstinence.

Pharmacokinetics (what the body does to the medicine)

Pharmacokinetics describes how a medicine is absorbed, distributed, metabolised, and eliminated. Knowing this helps explain dosing frequency and why kidney function can be important.

• Absorption: Acamprosate is absorbed after you take it, with the amount reaching the bloodstream depending on factors like individual metabolism and gastrointestinal conditions.
• Distribution: It reaches tissues where it can exert its effects on brain signalling systems.
• Metabolism: Acamprosate is not extensively broken down by the liver.
• Elimination: It is mainly eliminated through the kidneys (urinary excretion).

Why this matters: Because acamprosate is cleared by the kidneys, people with reduced kidney function may need caution, dose adjustment, or alternative management. Your clinician may check kidney function before starting and during treatment as appropriate.

Typical use in the UK

Campral is indicated to help maintain abstinence in adults who are dependent on alcohol and have already stopped drinking.

It is commonly used as part of a broader relapse-prevention plan that may include:

• Psychological support or counselling
• Motivational or behavioural therapy
• Management of triggers (e.g., stressful situations, social settings)
• Support for sleep, mood, and general wellbeing

Medicines alone rarely provide the full solution; the best outcomes often occur when medication is combined with ongoing support.

Indications (who it is for)

Campral is used for:

• Adults with alcohol dependence who have achieved abstinence

It is not intended for “detox” or for stopping withdrawal symptoms in the short term. The focus is relapse prevention after drinking has stopped.

Timing and how to take Campral

Campral is usually taken regularly through the day to maintain consistent levels. Exact dosing depends on individual factors such as kidney function and the specific tablet strength/brand.

General practical guidance:

• Take at the same times each day (e.g., morning, midday, and evening—exact schedule depends on the prescribed regimen).
• Try not to miss doses. If you do miss one, follow the advice given by your healthcare professional or the medicine leaflet.
• Keep taking it for as long as advised, even if you feel well.

Duration of treatment: Many people take Campral for months as part of a relapse-prevention plan. Your prescriber/clinical team will advise how long, based on your progress, risk of relapse, and overall plan.

Dosing (general information)

Dose must be individualised. The most important factors include your kidney function and the specific formulation you receive.

Typical adult dosing (general):

• Often involves multiple daily doses to reach an effective daily total.
• In some situations, kidney impairment may require a lower dose or a decision that Campral is not suitable.

Important: Do not change your dose without clinical advice. If you are unsure about your dose schedule, speak to your pharmacist and check the patient information leaflet included with your medicine.

Food interactions and swallowing tips

Food interactions: In most cases, Campral can be taken with or without food. However, some people find it easier to take tablets with meals or snacks to improve consistency and reduce stomach upset.

Swallowing:

• If tablets are difficult to swallow, speak to your pharmacist about practical options.
• Do not crush or alter tablets unless the pharmacist or leaflet confirms this is appropriate for your specific product.

Consistency matters: Taking doses at regular times is usually more important than timing around meals.

Alcohol and medicine interactions

Alcohol: The aim of Campral is to support abstinence. Drinking alcohol while taking acamprosate may undermine treatment goals and may worsen risk of relapse.

Key message: Campral is intended for people who have stopped drinking. If you drink again, contact your clinical team for advice—continued support and possible adjustment of the plan can make a difference.

Interactions with other medicines

Acamprosate has a pharmacokinetic profile that generally results in fewer liver-based metabolic interactions. However, interactions can still occur depending on your health status and other medicines.

Tell your healthcare professional if you take:

• Any medicines for mental health (e.g., antidepressants, antipsychotics)
• Medicines that affect the nervous system (e.g., sedatives)
• Medicines for epilepsy or sleep
• Any treatments that may affect kidney function
• Over-the-counter products, herbal remedies, or supplements

Kidney-related caution: Because acamprosate is cleared by the kidneys, medicines that also stress the kidneys (or conditions that reduce kidney function) may increase risk of side effects. Your clinician may review your medication list and kidney function tests.

Safety profile

Like all medicines, Campral can cause side effects. Not everyone experiences them, and many are mild and manageable.

Common or possible side effects

• Diarrhoea
• Nausea or stomach discomfort
• Headache
• Dizziness
• Fatigue or feeling weak

Less common but important side effects

• Allergic reactions (for example, rash, itching, swelling, or breathing difficulties)
• Significant worsening of diarrhoea leading to dehydration

If you develop signs of an allergic reaction or severe symptoms, seek urgent medical advice.

Who should take extra care?

Extra caution is particularly relevant if you have:

• Reduced kidney function
• Severe ongoing diarrhoea or dehydration risk
• Multiple medicines with complex health conditions

Your healthcare professional may arrange blood tests (such as kidney function) before or during treatment.

Practical use tips (to make treatment easier)

• Set reminders: Use phone alarms or blister pack calendars to reduce missed doses.
• Use a routine: Link doses to daily activities (e.g., breakfast, lunch, evening meal).
• Stay hydrated: If diarrhoea occurs, drink fluids and speak to your pharmacist/GP if it becomes persistent.
• Plan for cravings: Write down coping strategies (call a friend, attend support meetings, avoid high-risk triggers).
• Keep support in place: Continue counselling/therapy if you’re receiving it—medication works best alongside support.
• Don’t stop abruptly without advice: If you stop early, relapse risk may rise. If you need to stop due to side effects, seek advice first.

Managing side effects: For mild diarrhoea or stomach upset, simple measures may help initially, but persistent or severe symptoms should be discussed with a healthcare professional.

What to expect during treatment

Campral helps maintain abstinence, but it doesn’t “remove” all risk of cravings. Many people notice:

• Gradual strengthening of relapse resistance when combined with support
• Cravings may still happen, particularly during stressful periods
• Consistency and coping strategies remain essential

It can take time to build new routines and reduce triggers. If you relapse or begin drinking again, it doesn’t mean your effort has failed—seek support promptly to re-plan your next steps.

Alternative options for alcohol dependence relapse prevention (UK context)

There are several approaches used in the UK to support recovery from alcohol dependence. Your eligibility and best choice depend on your medical history, kidney/liver function, and personal circumstances.

Medication options (general)

• Naltrexone (for some people, reduces the rewarding effects of alcohol)
• Acamprosate (Campral) – supports maintaining abstinence
• Other medically supervised approaches depending on comorbidities and local services

Non-medicine supports

• Psychological therapies (e.g., CBT, motivational techniques)
• Peer support and structured community programmes
• Specialist alcohol services (including relapse-prevention planning)

If you’re considering alternatives or stopping Campral, speak with a healthcare professional to tailor the plan to your needs and safety considerations.
