Acamprosate (Campral): What It Is
A general-education explainer on acamprosate, where it fits among FDA-approved AUD medications, and what to ask a clinician.
Acamprosate, also known by the brand name Campral, is one of three FDA-approved medications for alcohol use disorder. The other two are disulfiram and naltrexone. Acamprosate is generally framed as a relapse-prevention medication for people who have already stopped drinking and want support staying stopped. This page is general education, not a dosing guide, not an efficacy ranking, not a prescription pathway, and not a substitute for a clinician conversation.
Key takeaways
- Acamprosate is an AUD medication to discuss with a licensed clinician.
- It is usually talked about in the context of staying abstinent after stopping, not as an at-home withdrawal plan.
- This article does not compare acamprosate, naltrexone, and disulfiram as "best to worst."
- Kidney function, medical history, goals, and other medications are clinician questions.
- This site is educational today and does not provide medical care, prescriptions, accounts, payments, or health questionnaires.
What acamprosate is
NIAAA's treatment-options resource lists acamprosate, disulfiram, and naltrexone as FDA-approved medications for AUD, alongside behavioral therapies and mutual-support groups. That list is a category map, not a ranking.
Acamprosate is often discussed for people who have already stopped drinking and want help maintaining abstinence. That distinction matters for a reader whose goal is moderation. It does not mean your goal is wrong; it means this medication question belongs with a clinician who can match the option to the goal and medical context.
How it is thought to work
Acamprosate is generally described as helping stabilize brain signaling that has been disrupted by chronic heavy drinking. The exact mechanism is still discussed in scientific language, so this page stays at the category level. It will not make a stronger mechanism claim than the public-health record supports.
It is also not a withdrawal medication. If you are drinking daily and planning to stop, read understanding alcohol withdrawal symptoms and treatment options before treating any long-term medication question as the first step.
What the treatment gap says
NIAAA documents that roughly 28.9 million U.S. adults 18+ met criteria for AUD in 2024 NSDUH. NIAAA's treatment summary also documents that only a minority of adults with past-year AUD receive any treatment in a given year, and the share receiving FDA-approved AUD medications is smaller still.
That gap matters because medication questions often carry shame: "If I need medication, is my problem worse than I thought?" NIAAA identifies stigma as a barrier to alcohol-related help-seeking; needing to ask about medication is not a moral failure.
What to ask a clinician
A clinician may ask about your current drinking, whether you have already stopped, kidney function, liver history, other medications, pregnancy status, mental health, prior withdrawal, and support at home. Those questions are not hoops to prove you deserve help. They are how medication decisions get made safely.
NIAAA's telehealth-options summary lists professional telehealth, self-guided online programs, and online mutual-support communities as care pathways for AUD that can include medication management. This page does not say any specific service, app, or clinic can prescribe acamprosate for you.
It helps to describe the drinking pattern in standard terms. NIAAA defines a U.S. standard drink as 0.6 fluid ounces, or 14 grams, of pure alcohol. NIAAA defines binge drinking as a pattern that typically brings BAC to 0.08% or higher, often 5 or more drinks for males or 4 or more drinks for females in about 2 hours. Those definitions are not a fit test, but they help keep the conversation specific.
The abstinence and moderation question
Many readers land here because they are comparing medication names, not because they have already chosen a goal. Acamprosate is commonly framed around staying stopped after stopping. If your goal is to reduce rather than stop, say that plainly to the clinician. The answer may be acamprosate, a different medication discussion, behavioral support, a withdrawal-safety plan first, or something else entirely.
The point is not to force yourself into the medication's frame. The point is to bring the honest frame to care: what you want, what you have tried, what happened when you tried to stop or cut back, and what would make the next attempt safer.
How to compare acamprosate without ranking it
It is natural to ask whether acamprosate is "better" than naltrexone or disulfiram. That question is usually too blunt. A better clinician-facing question is, "Given my goal and history, which medication category is worth discussing first?"
Acamprosate, naltrexone, and disulfiram are not three versions of the same promise. They are different tools with different clinical fits. A person who has already stopped and wants help staying stopped may be asking a different question from a person trying to reduce drinking while still drinking, or a person who needs a safety plan before stopping. This page keeps the comparison at that level because individual selection belongs in care.
If a medication does not fit, that is not the end of treatment. AUD care can be iterative: goals change, side effects matter, support changes, and the next conversation can be adjusted.
What this page will not tell you to do
It will not give a dose, tablet count, lab cutoff, side-effect frequency, response percentage, insurance estimate, or pharmacy advice. It will not say whether you can or cannot drink while taking acamprosate. It will not promise that any company, including Clero, can prescribe it today.

FAQ
Is acamprosate the same as naltrexone?
No. They are different FDA-approved medications for AUD and are generally discussed in different clinical contexts. This page does not rank them.
Is acamprosate for withdrawal?
This page does not frame acamprosate as withdrawal management. If withdrawal is a concern, talk to a clinician before stopping or reducing alcohol.
Can my regular doctor prescribe acamprosate?
Some primary-care clinicians and other licensed clinicians can discuss AUD medications. Whether it fits you is an individual medical question.
What to do next
If acamprosate came up in a search or clinician conversation, write down your goal, current drinking pattern, prior withdrawal history, and questions. Bring that to a licensed clinician. For confidential referral help, SAMHSA's National Helpline is available 24/7 at 1-800-662-HELP.
