Acamprol (acamprosate calcium) is a prescription medication specifically formulated to support long-term abstinence in patients recovering from alcohol dependence. It functions by restoring the balance of neurotransmitter systems in the brain disrupted by chronic alcohol use, thereby reducing the psychological distress and cravings associated with withdrawal. Clinically proven and widely recommended, Acamprol is an integral component of comprehensive treatment programs that include counseling and psychosocial support. Its targeted mechanism offers a pharmacological strategy to sustain sobriety and improve quality of life in motivated individuals.

Common use
Acamprol is indicated for the maintenance of abstinence from alcohol in patients with alcohol dependence who are abstinent at the time of treatment initiation. It is most effective when used as part of a comprehensive management program that includes counseling, support groups, and behavioral interventions. Treatment should be initiated as soon as possible after the acute withdrawal period, once physical withdrawal symptoms have subsided. It is intended for use in motivated patients committed to achieving sustained sobriety.
Dosage and direction
The recommended dosage of Acamprol for most adults is two 333 mg tablets taken three times daily (total daily dose 1998 mg). Tablets should be swallowed whole with water and not crushed or chewed. It may be taken with or without food, though consistent timing is advised to maintain stable drug levels. Dosage adjustment is recommended in patients with moderate renal impairment (creatinine clearance 30–50 mL/min): one 333 mg tablet three times daily. Not recommended in severe renal impairment (creatinine clearance ≤30 mL/min). Treatment duration should be individualized, often continuing for several months to a year or longer based on clinical response.
Precautions
Acamprol should be used with caution in patients with a history of depression or suicidal ideation, as alcohol dependence is associated with an increased risk of depressive symptoms. Renal function should be assessed before initiation and periodically during treatment. It is not indicated for the treatment of acute alcohol withdrawal symptoms. Patients should be advised that Acamprol does not eliminate or reduce the intoxicating effects of alcohol and should not be used to facilitate controlled drinking. Use during pregnancy or breastfeeding should be considered only if clearly needed and under strict medical supervision.
Contraindications
Acamprol is contraindicated in patients with severe renal impairment (creatinine clearance ≤30 mL/min). It should not be used in patients with known hypersensitivity to acamprosate calcium or any excipients in the formulation. It is not intended for use in patients who have not achieved abstinence prior to treatment initiation. Contraindicated in children and adolescents under 18 years of age due to lack of safety and efficacy data in this population.
Possible side effects
The most commonly reported adverse reactions include diarrhea, nausea, abdominal pain, pruritus, and rash. These are generally mild to moderate and often transient. Less frequently, patients may experience fluctuations in libido, dizziness, headache, or insomnia. Cases of suicidal ideation, depression, and anxiety have been reported, though a direct causal relationship has not been firmly established. Severe cutaneous reactions such as Stevens-Johnson syndrome are very rare. Patients should be monitored for emergent mood changes or severe dermatological symptoms.
Drug interaction
No clinically significant pharmacokinetic drug interactions have been established. However, given its renal excretion and mechanism, caution is advised when used concomitantly with other centrally acting agents or drugs that affect renal function. Acamprol does not interact with disulfiram or diazepam, but combined use with naltrexone may offer synergistic benefits in some patients. Always inform your healthcare provider of all medications, including over-the-counter drugs and herbal supplements.
Missed dose
If a dose is missed, it should be taken as soon as remembered unless it is nearly time for the next scheduled dose. In that case, skip the missed dose and resume the regular dosing schedule. Do not double the dose to make up for a missed one. Consistent adherence is important to maintain therapeutic effect; use of a pill organizer or alarm may help support routine administration.
Overdose
Cases of overdose have been reported and were generally characterized by gastrointestinal symptoms (such as diarrhea) and dizziness. No specific antidote is available. Treatment should be symptomatic and supportive. Gastric lavage may be considered if ingestion was recent. Hemodialysis may remove acamprosate, though clinical data are limited. In case of suspected overdose, seek immediate medical attention or contact a poison control center.
Storage
Store Acamprol tablets at room temperature (15–30°C or 59–86°F) in a dry place, protected from light and moisture. Keep the tablets in their original blister packaging until use. Do not store in bathrooms or near sinks. Keep out of reach of children and pets. Do not use beyond the expiration date printed on the packaging.

Reviews
Clinical studies and meta-analyses have consistently demonstrated the efficacy of acamprosate in supporting abstinence, with a number needed to treat (NNT) of approximately 9–12. It is endorsed by treatment guidelines including those from the World Health Organization and the American Psychiatric Association. Patient reports often highlight reduced craving intensity and improved ability to engage in recovery-oriented activities, though individual experiences may vary. Long-term real-world evidence supports its role as a valuable tool in multidisciplinary addiction treatment.
