Campral (Acamprosate) — Patient Information (UK)
Campral contains acamprosate, a medicine used to help people maintain abstinence from alcohol after they have stopped drinking. It can reduce the likelihood of relapse for some individuals and is often used alongside support such as counselling or structured programmes.
This page explains how Campral works, how it’s used, what to expect, and important safety information. If you have questions or concerns, speak to a healthcare professional.
Quick facts
- Active ingredient: Acamprosate
- Common purpose in the UK: Support with maintaining alcohol abstinence
- How it may help: Helps normalise brain signalling related to alcohol dependence
- Typical schedule: Taken three times daily (morning, midday, evening)
- Time to benefit: Ongoing use is usually needed; effects are typically aimed at reducing relapse risk over time
What is Campral?
Campral is an alcohol dependence medicine. It is designed for people who have already stopped drinking and want help to stay abstinent. It is not intended to treat acute alcohol withdrawal symptoms.
In the UK, Campral is supplied in tablet form (strengths and brand presentation may vary). Your pharmacist or healthcare professional can confirm the exact product you are receiving.
How does Campral work? (Mechanism of action)
Long-term heavy alcohol use can change the balance of chemical signals in the brain. Acamprosate is thought to help restore this balance by influencing neurotransmission, particularly in systems involving:
- GABA (gamma-aminobutyric acid) — associated with inhibitory signalling
- Glutamate — associated with excitatory signalling
Clinically, this may reduce the “pull” of alcohol cues and help the brain’s networks settle after stopping. It is a maintenance approach rather than a quick “anti-craving” rescue.
Pharmacokinetics: how the body handles acamprosate
Pharmacokinetics describes what happens to a drug after you take it.
- Absorption: Acamprosate is absorbed after oral dosing. Food does not usually prevent absorption, but taking it consistently helps maintain stable levels.
- Distribution: It distributes throughout the body, reaching relevant tissues.
- Metabolism: Acamprosate is not extensively metabolised by the liver.
- Elimination: It is mainly cleared via the kidneys. This makes kidney function a key consideration for safe use.
- Half-life: The medicine is designed for regular dosing to maintain effect through the day.
Clinical implication: Because kidney function matters, dose adjustments or avoidance may be needed for people with reduced renal function (kidney impairment).
What is Campral used for in the UK?
Campral is indicated for the maintenance of abstinence in patients dependent on alcohol. It is generally used after alcohol has been stopped, as part of a broader plan that may include:
- Psychosocial support (for example counselling or talking therapies)
- Support groups
- Relapse-prevention strategies
- Monitoring of overall health and wellbeing
It is not a treatment for acute withdrawal (such as delirium tremens). Acute withdrawal needs urgent medical management.
Who might be suitable?
Campral may be considered for people who:
- Have alcohol dependence
- Have already stopped drinking and aim to remain abstinent
- Can follow a three-times-daily regimen
- Have kidney function that allows safe use (this is assessed before starting)
Suitability depends on individual health circumstances. A clinician or pharmacist can check any medicines you take and your kidney function before recommending it.
Dosing and timing
Important: Always follow the dosing instructions provided by a healthcare professional. The below is general guidance to help you understand the typical approach.
Typical adult dosing (general information)
For many adults, the usual dose is:
- Three times daily (morning, midday, evening)
The exact tablet number and strength will depend on the specific formulation you receive. Your pharmacy label will show the correct directions.
When to start
Campral is intended for maintenance after stopping alcohol. Clinicians typically aim for starting once alcohol use has ceased, as part of a relapse-prevention plan.
How to take it
- Take it at the same times each day where possible.
- Swallow tablets with water.
- If you miss a dose, do not double up to make up for it. Take your next dose at the usual time.
How long to use it
Campral is used for relapse prevention over time. The duration varies from person to person depending on recovery progress, support needs, and the overall plan agreed with healthcare professionals.
Food interactions and taking with meals
In many patients, Campral can be taken with or without food. That said, consistency is helpful:
- If you find that food reduces stomach upset for you, take it after meals.
- Try not to drastically change your routine from day to day.
Practical tip: Linking doses to daily habits (e.g., breakfast, lunch, evening meal) can improve adherence to a three-times-daily schedule.
Alcohol and medicine interactions
Because Campral is used to support alcohol abstinence, drinking alcohol while taking it is not the goal. Alcohol can undermine treatment and increase relapse risk.
Interactions with other medicines
Acamprosate has a relatively low tendency for liver-based drug interactions because it is not extensively metabolised by the liver. However, interactions can still occur indirectly through effects on health, adherence, or kidney function.
When starting Campral, it’s important to tell a pharmacist or clinician about:
- All prescription medicines
- Over-the-counter products (including sedatives and sleep aids)
- Herbal remedies and supplements
- Any history of kidney problems
Medicines that may require extra caution
Because acamprosate is primarily cleared by the kidneys, medicines that affect kidney function—or situations that reduce kidney function—may require review. Examples include:
- Dehydration
- Some medicines that can stress the kidneys
- Use of diuretics (“water tablets”) in certain circumstances
This does not mean you can’t take Campral with other medicines, but it does mean medication review is important.
Indications and evidence-based use
Campral is used for maintenance of abstinence in people who are alcohol dependent. It may be especially helpful when combined with other relapse-prevention strategies, such as:
- Structured counselling
- Motivational interviewing approaches
- Recovery programmes
- Regular check-ins and support
Effectiveness varies across individuals. Some people may notice improvement in stability and reduced urge-related distress; others may benefit more when combined with behavioural and psychosocial supports.
Safety profile: side effects and precautions
Common side effects
Like all medicines, Campral can cause side effects. Commonly reported ones may include:
- Diarrhoea
- Nausea
- Abdominal discomfort
- Headache
- Dizziness
These effects may be dose-related and often improve as your body adjusts. If symptoms are persistent or severe, seek medical advice.
Serious side effects (seek urgent advice)
Contact urgent medical help if you develop signs of a serious allergic reaction, such as:
- Swelling of the face, lips, tongue, or throat
- Severe rash or itching with breathing difficulties
- Fainting or severe dizziness
Kidney impairment and why it matters
Because acamprosate is cleared by the kidneys, kidney function strongly influences safe use. Your clinician/pharmacist may:
- Check kidney function before starting
- Consider dose adjustment or avoidance if kidney function is significantly reduced
- Advise monitoring if kidney status changes
Pregnancy and breastfeeding
If you are pregnant, trying to conceive, or breastfeeding, discuss risks and benefits with a healthcare professional. Medicines used for alcohol dependence should be considered carefully on an individual basis.
Driving and operating machinery
Campral is not typically associated with major impairment of alertness for most people. However, some individuals experience dizziness or unsteadiness. Avoid driving or using machinery if you feel affected.
Practical use tips (to support adherence and recovery)
- Create a routine: Tie each dose to a daily anchor (breakfast, lunchtime, evening).
- Use reminders: Smartphone alarms, pill boxes, or blister packs can help.
- Plan for gastrointestinal effects: If diarrhoea occurs, staying hydrated and taking doses with meals (if suitable) may help; speak to a pharmacist if it’s troublesome.
- Don’t stop suddenly without advice: If you feel you want to stop, discuss with a healthcare professional—maintenance therapy is often most useful when continued as planned.
- Pair medicine with support: Counselling, peer support, and relapse-prevention planning often improve outcomes.
- Relapse plan: If you drink accidentally, seek guidance quickly rather than waiting. A healthcare professional can help adjust the recovery plan.
Alternative options (if Campral isn’t suitable)
In the UK, treatment for alcohol dependence may include medication, psychosocial support, or a combination. Alternative medication options that clinicians may consider include:
- Naltrexone — can help reduce heavy drinking in some people by affecting opioid receptors
- Disulfiram — works differently and may discourage alcohol use by causing unpleasant reactions when alcohol is taken
- Other supportive interventions — including counselling and structured recovery programmes
Which option is best depends on your medical history, goals (abstinence versus reduced drinking), and suitability (e.g., kidney or liver status). A healthcare professional can help you compare benefits and risks.
