Acamprosate (brand name Campral) is an FDA-approved medication that plays a unique role in alcohol recovery. Unlike medications that reduce cravings or create aversion to alcohol, acamprosate works by stabilizing brain chemistry disrupted by chronic alcohol use. For many individuals committed to sobriety, it provides crucial neurochemical support during the critical early recovery phase.
What Is Acamprosate?
Acamprosate is a synthetic compound structurally similar to the amino acid taurine. It's FDA-approved for maintaining abstinence in alcohol-dependent individuals. Available as oral tablets (666 mg), it's typically dosed three times daily. Unlike some other medications, acamprosate has minimal interactions and does not require baseline blood work, making it relatively straightforward to initiate.
How Does Acamprosate Work?
Chronic alcohol use disrupts the balance between two major neurotransmitter systems: GABA (which calms the brain) and glutamate (which excites it). Alcohol initially increases GABA and decreases glutamate, creating a sense of relaxation. With chronic use, the brain adapts by reducing GABA and increasing glutamate. When alcohol is withdrawn, this imbalance triggers anxiety, insomnia, and hyperexcitability—making early sobriety extremely uncomfortable.
Acamprosate helps restore this balance by modulating glutamate signaling and supporting GABA function. This neurochemical stabilization reduces post-acute withdrawal symptoms (PAWS) and diminishes the emotional discomfort that often triggers relapse in early recovery.
Who Benefits Most from Acamprosate?
Acamprosate is particularly beneficial for individuals recently detoxified from alcohol who struggle with anxiety, insomnia, or emotional dysregulation in early sobriety. It's also a good choice for those who cannot tolerate naltrexone or for whom naltrexone has been ineffective. Because acamprosate doesn't reduce cravings directly like naltrexone does, some benefit from combining both medications.
Starting Acamprosate: Dosing and Timeline
The standard dose is two 333 mg tablets (666 mg total) three times daily, beginning as soon as detoxification is complete. Most individuals tolerate acamprosate well. The most common side effect is mild gastrointestinal upset, which often resolves within the first week. Diarrhea, nausea, and rarely headaches may occur. Many of these side effects improve over time.
Acamprosate typically requires 5-7 days to reach steady-state levels. Improvements in mood stability and sleep often become noticeable within 2-3 weeks.
Important Considerations
- Acamprosate should only be started after complete detoxification; starting during active withdrawal is not recommended.
- Kidney function should be assessed before starting, especially in older adults or those with renal impairment.
- Acamprosate does not prevent relapse on its own—it must be paired with psychotherapy, support groups, and behavioral interventions.
- If you miss doses, take them as soon as remembered, but do not double-dose.
- Do not abruptly stop acamprosate; taper under medical guidance to prevent rebound symptoms.
Acamprosate vs. Naltrexone vs. Disulfiram
Each medication addresses alcohol recovery differently. Naltrexone blocks reward pathways (reducing cravings), acamprosate stabilizes neurochemistry (easing withdrawal discomfort), and disulfiram creates aversion (discouraging drinking through unpleasant reactions). Your psychiatrist will recommend based on your clinical picture, co-occurring conditions, and personal preferences.
Long-Term Outcomes with Acamprosate
Research indicates that acamprosate is most effective when combined with counseling and behavioral support. Studies show it helps maintain abstinence and may reduce relapse rates by 15-20% compared to placebo. The medication works best for individuals committed to recovery and actively engaged in therapy.

Frequently Asked Questions
Can I drink alcohol while taking acamprosate?
Acamprosate does not prevent drinking or cause unpleasant reactions if alcohol is consumed. It works by supporting your neurochemistry during recovery, making sobriety more emotionally sustainable. It's intended for individuals committed to abstinence.
How long should I take acamprosate?
Duration varies based on individual recovery needs. Many individuals benefit from 6-12 months of therapy. Some require longer-term maintenance, especially those with multiple relapse history. Your prescriber will help determine the appropriate timeline.
Does acamprosate interact with other medications?
Acamprosate has minimal drug interactions, making it relatively safe to combine with other psychiatric medications. Always inform your prescriber of all medications and supplements to ensure safety.
