Acamprol (acamprosate calcium) is a prescription medication specifically formulated to support the maintenance of abstinence in patients with alcohol dependence who have achieved initial withdrawal and are committed to continued sobriety. It functions by helping to stabilize the chemical balance in the brain, which is often disrupted by chronic alcohol use. By targeting the neuroadaptive changes caused by long-term alcohol consumption, Acamprol aids in reducing the physiological craving for alcohol, thereby supporting long-term recovery efforts as part of a comprehensive treatment plan that includes counseling and psychosocial support.

Common use
Acamprol is indicated for the maintenance of abstinence from alcohol in patients with alcohol dependence who are abstinent at treatment initiation. It is most effective when integrated into a comprehensive management program that includes psychological support, behavioral therapy, and social reinforcement. Treatment should be initiated as soon as possible after the acute withdrawal period, once physical withdrawal symptoms have subsided. It is not intended for use in patients who are actively drinking or experiencing acute withdrawal symptoms.
Dosage and direction
The recommended dose of Acamprol for most patients is two 333 mg tablets taken three times daily (total daily dose 1998 mg). For patients with moderate renal impairment (creatinine clearance 30–50 mL/min), the dosage should be reduced to one 333 mg tablet three times daily. It is not recommended for patients with severe renal impairment (creatinine clearance ≤30 mL/min). Tablets should be swallowed whole with water and can be taken with or without food, though consistent timing is advised to maintain stable plasma concentrations. Treatment should continue even during periods of perceived stability, and discontinuation should be medically supervised.
Precautions
Acamprol should be used with caution in patients with renal impairment; dosage adjustment is necessary for moderate impairment, and it is contraindicated in severe impairment. It is not recommended during pregnancy unless clearly needed, and breastfeeding should be avoided due to insufficient safety data. Patients with a history of depression or suicidal ideation should be closely monitored, as alcohol dependence itself carries an increased risk of depression. It does not eliminate or reduce withdrawal symptoms, and patients should be advised that Acamprol is most effective when combined with a comprehensive abstinence program.
Contraindications
Acamprol is contraindicated in patients with severe renal impairment (creatinine clearance ≤30 mL/min). It should not be used in patients who are hypersensitive to acamprosate calcium or any excipients in the formulation. It is not indicated for the treatment of acute alcohol withdrawal symptoms. Use during pregnancy is not recommended unless the potential benefit justifies the potential risk to the fetus.
Possible side effects
The most commonly reported adverse reactions include diarrhea, nausea, abdominal pain, pruritus, and various rash manifestations. These are generally mild to moderate and often transient. Less frequently, patients may experience fluctuations in libido, dizziness, headache, insomnia, or anxiety. Serious side effects are rare but may include severe allergic reactions, suicidal thoughts, or clinical depression. Patients should report any persistent or severe symptoms to their healthcare provider promptly.
Drug interaction
Acamprol is not metabolized by the liver and does not inhibit cytochrome P450 enzymes, reducing its potential for pharmacokinetic interactions. However, concomitant use with naltrexone may increase the incidence of diarrhea and abdominal discomfort. No clinically significant interactions have been observed with antidepressants, anxiolytics, hypnotics, or other medications commonly used in this patient population. Nevertheless, all concomitant medications should be reviewed by the prescribing physician.
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, the missed dose should be skipped, and the regular dosing schedule resumed. Patients should not double the dose to make up for a missed one. Consistency in dosing is important to maintain therapeutic plasma levels and efficacy.
Overdose
There is limited clinical experience with Acamprol overdose. Reported cases have primarily involved diarrhea and gastrointestinal discomfort. There is no specific antidote; treatment should be symptomatic and supportive. Hemodialysis may remove acamprosate, though its efficacy in overdose situations has not been established. In cases of suspected overdose, medical attention should be sought immediately.
Storage
Acamprol tablets should be stored at room temperature (15–30°C or 59–86°F) in a dry place, protected from light and moisture. Keep the medication in its original container, tightly closed, and 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 Acamprol in supporting abstinence, with many patients reporting reduced cravings and improved ability to engage in recovery programs. It is regarded by specialists as a valuable component in a multifaceted approach to alcohol dependence treatment. Patient experiences often highlight the importance of combining medication with counseling for optimal outcomes.
