Campral (Acamprosate) — Patient Information (Australia)

Campral is a medicine used to help people maintain abstinence after stopping alcohol. It contains acamprosate, which works in the brain’s chemical pathways involved in alcohol dependence. This page explains how Campral works, when it’s taken, key safety information, and practical tips to support treatment.

Important: Alcohol dependence is a complex condition. Medicines work best when combined with support such as counselling, education, and relapse-prevention strategies.

1) Basic product information

• Medicine: Campral
• Active ingredient: Acamprosate
• Common form: Tablets (strengths vary by market; check the pack for your exact strength)
• ATC code: N07BB03
• Therapeutic use: Alcohol dependence—maintenance of abstinence
• Availability in Australia: Commonly supplied through Australian pharmacies and approved distribution channels

2) What Campral is used for (indications)

Campral (acamprosate) is indicated to help maintain abstinence in people who have already stopped drinking. It is most beneficial for those with alcohol dependence who are committed to continuing alcohol-free living.

It is generally used as part of a broader plan, which may include:

• Psychosocial support or counselling
• Trigger management and coping strategies
• Health monitoring (e.g., nutrition, liver function if needed)
• Support for co-existing conditions (e.g., anxiety, depression)

3) How Campral works (mechanism of action)

Alcohol dependence changes brain signalling. Over time, the brain adapts to the presence of alcohol, affecting balance between key neurotransmitter systems. When alcohol is stopped, this balance can shift, contributing to cravings, sleep disturbance, and discomfort.

Acamprosate is thought to help restore balance by acting on the glutamate system:

• It modulates signalling related to excitatory neurotransmission.
• It may help reduce the “hyperexcitability” that can occur during early abstinence.
• As a result, it can help reduce the likelihood of relapse and support sustained abstinence.

Unlike medicines that create an unpleasant reaction to alcohol, Campral’s effect is aimed at brain chemical stability after stopping drinking.

4) Typical course and timing

Campral is commonly used as a maintenance medicine—typically started after alcohol has been stopped.

• Start timing: Begin after the person has stopped drinking (often once abstinence is established, as advised by the treating clinician and the product information).
• Ongoing use: Treatment is usually continued for a period of months to support early recovery and long-term maintenance.

Consistency matters: Taking Campral at the correct times each day helps maintain stable levels and may improve effectiveness.

5) How to take Campral (dosing guidance)

Dose may vary based on kidney function and individual factors. Always follow the instructions provided with your specific pack and advice from your healthcare professional.

Common adult dosing approach

In many settings, acamprosate dosing for alcohol dependence is taken in divided doses across the day (often three times daily), because it has a dosing schedule designed to maintain therapeutic levels.

Renal (kidney) function is important: If kidney function is reduced, the dose may need adjustment and closer monitoring may be required. This is because acamprosate is eliminated mainly through the kidneys.

Missed dose advice

• If you miss a dose, take it when you remember unless it’s close to the next scheduled dose.
• Do not take double doses to make up for a missed one.

If you’re unsure, ask your pharmacist for personalised advice based on your schedule and pack instructions.

6) Pharmacokinetics (how the body processes it)

Pharmacokinetics describes how the body absorbs, distributes, metabolises, and excretes a medicine.

• Absorption: Acamprosate is absorbed after oral dosing. Food may influence the speed of absorption.
• Distribution: It distributes throughout the body; protein binding is not typically the major driver of clearance.
• Metabolism: Acamprosate is not extensively metabolised by the liver.
• Elimination: It is largely eliminated through the kidneys as unchanged drug.
• Half-life: The effective half-life supports divided dosing throughout the day.

Why this matters: Because kidney elimination is the main route, reduced kidney function can lead to higher drug levels and a higher chance of side effects if not adjusted appropriately.

7) Food and Campral interactions

Many patients ask whether they must take Campral with food. In general, food interactions are relatively modest compared with some other medicines.

However, to support consistent absorption:

• Follow the dosing instructions on your product label.
• If the instructions allow flexibility, taking it around the same mealtimes each day may help with adherence.
• If you experience stomach upset or other symptoms, speak to your pharmacist about whether taking it with food (if permitted) helps.

Key principle: Maintain a regular schedule. If your clinician recommends a specific approach (e.g., due to tolerability), follow that advice.

8) Alcohol and medicine interactions

Campral is used to support people who are already abstinent. Continuing to drink alcohol may undermine treatment goals.

Alcohol during treatment

• Do not drink alcohol while using Campral if your goal is abstinence.
• If you relapse, seek support promptly. The overall care plan can be reviewed and adjusted.

Other medicines

Acamprosate has a relatively low likelihood of major metabolic interactions (because it is not extensively processed by the liver). Still, interactions can occur based on your overall medication list and health status.

Tell your pharmacist if you take:

• Medicines for anxiety or sleep
• Medicines affecting the kidneys (including some diuretics or other renally cleared drugs)
• Over-the-counter medicines or supplements

Always check: Even when interaction risk is low, individual health factors (especially kidney function) can change how you should take Campral.

9) Safety profile and side effects

Most people tolerate Campral well. As with all medicines, it can cause side effects. The table below lists commonly reported effects and what to do.

Seek urgent help if

• You develop signs of a severe allergic reaction (e.g., facial swelling, difficulty breathing, widespread rash)
• Symptoms are severe, rapidly worsening, or you feel seriously unwell

Special safety considerations

• Kidney impairment: Extra caution is needed because acamprosate is cleared by the kidneys.
• Dehydration: If you have diarrhoea, drinking enough fluids is important to prevent dehydration.
• Co-existing liver disease: Acamprosate is not mainly metabolised by the liver, but individual circumstances still matter—follow professional advice.
• Pregnancy and breastfeeding: Discuss risk–benefit with a healthcare professional.
• Older adults: Kidney function often changes with age, so dose and monitoring may be adjusted.

10) Practical use tips (how to get the most from Campral)

Medication is only one part of recovery. The tips below may improve day-to-day success:

• Use a routine: Link doses to regular activities (e.g., breakfast, lunch, evening).
• Set reminders: Phone alarms or blister-pack schedules help prevent missed doses.
• Track cravings: If cravings increase, note the time, context, and what helped—this information can guide adjustments to your support plan.
• Stay connected: Attend counselling or peer support where available. Many people benefit from structured follow-up.
• Hydration and diet: If you experience gastrointestinal upset, staying hydrated can help.
• Avoid “testing” alcohol: Even small amounts can trigger patterns that lead to relapse.
• Plan for high-risk times: Weekends, payday, or social events may be challenging—prepare coping strategies in advance.

11) Alternative options for alcohol dependence in Australia

There are different medicines and non-medicine supports used for alcohol dependence. Choice depends on your goals (abstinence vs reducing drinking), health history, side effects, and clinician assessment.

Other medications commonly considered

• Naltrexone (oral or injectable forms in some settings): may help reduce heavy drinking for some people.
• Disulfiram: aims to deter alcohol use by causing an unpleasant reaction if alcohol is taken.
• Benzodiazepines (short-term, clinician-guided): may be used for alcohol withdrawal management under medical supervision.

Non-medicine options

• Psychological therapies (e.g., cognitive behavioural therapy)
• Motivational interviewing
• Community and peer support programs
• Relapse-prevention planning and family support strategies

Your pharmacist or clinician can help compare options based on your situation, including kidney function and previous medication experiences.

12) Market and legal context for Australia
