Acamprosate Side Effects: What You Should Know
Acamprosate, commonly known by the brand name Campral, is a prescription medication that supports individuals in recovery from alcohol use disorder. By helping to restore balance to brain chemistry disrupted by long-term alcohol use, it can reduce cravings and make sobriety more sustainable.
Like any medication, though, understanding potential acamprosate side effects and how to manage them safely is an important part of a successful recovery journey.
What Is Acamprosate, and How Does It Help with Alcohol Addiction?
Acamprosate is an FDA-approved medication for alcohol dependence. Sometimes called Campral or acamprosate calcium, it helps individuals who have already stopped drinking maintain abstinence by stabilizing neurotransmitters in the brain.
Unlike disulfiram (Antabuse), which causes unpleasant reactions when alcohol is consumed, Acamprosate helps reduce the urge to drink by restoring chemical balance. It is non-addictive and generally safe when used under medical supervision.
Common Acamprosate Side Effects During Recovery
Most people tolerate acamprosate well, but mild to moderate side effects can occur, especially in the first few weeks of use. The most frequently reported side effects include:
- Digestive symptoms: diarrhea, nausea, or upset stomach
- Changes in appetite: reduced hunger or altered eating patterns
- Sleep disturbances: difficulty falling or staying asleep
- Mood symptoms: feeling sad, mild anxiety, irritability, or restlessness
- Fatigue: Tiredness or loss of interest or pleasure
These effects often fade as the body adjusts. However, persistent symptoms should always be discussed with a healthcare professional.
Serious Acamprosate Side Effects and When to Seek Medical Help
While uncommon, acamprosate serious side effects can occur. Contact your doctor or seek emergency help immediately if you notice:
- Allergic reactions, such as rash, itching, swelling, or difficulty breathing
- Severe mood changes, including depression or thoughts of self-harm
- Chest pain or irregular heartbeat
- Burning, tingling, or numbness in the hands, feet, arms, or legs
These symptoms are rare but require urgent medical evaluation. Never stop or alter your dosage without consulting your provider.
How Acamprosate Works in Alcohol Recovery Treatment
While acamprosate doesn’t eliminate cravings entirely, it helps the brain heal from long-term alcohol exposure. By restoring normal neurotransmitter activity, it reduces emotional distress and withdrawal-related anxiety that can lead to relapse.
It is most effective when combined with behavioral therapy, counseling, and structured support—all of which are available at Monterey Bay Recovery. Medication alone isn’t a cure but an important tool within a comprehensive recovery plan.
Tips for Managing Acamprosate Side Effects Safely
You can minimize the side effects of acamprosate calcium and improve treatment success by following a few key guidelines:
- Follow prescribed dosage: Take acamprosate exactly as directed by your doctor.
- Stay hydrated: Drinking plenty of water can help reduce digestive symptoms.
- Eat balanced meals: Proper nutrition supports your body’s adjustment to medication.
- Track your symptoms: Keep a journal to share accurate feedback with your care team.
- Avoid alcohol: Combining acamprosate with alcohol reduces its effectiveness.
Open communication with your provider helps ensure the safest and most effective treatment outcome.

Acamprosate isn’t suitable for everyone. People with severe kidney disease or certain medical conditions should avoid it. Always inform your healthcare provider about any:
