Acamprosate is contraindicated:

– in the event of renal insufficiency (serum creatinine> 120 µmol / l);

In women who are breast-feeding (see section Pregnancy and breast-feeding ).


How it works ?

  1. Absorption of acamprosate through the gastrointestinal tract is moderate. It is slow and sustained, with significant inter-individual variability.
  2. Administration of acamprosate with food decreases the bioavailability of the drug compared to administration on an empty stomach.
  3. Steady state is reached within 5-7 days after repeated oral administration.
  4. Acamprosate is not bound to plasma proteins.
  5. The elimination of acamprosate occurs exclusively via the renal route and in unchanged form, the renal clearance of acamprosate being almost identical to the total plasma clearance. In addition, taking acamprosate by injection shows that there is a linear relationship between the degree of renal failure and the prolongation of the plasma elimination half-life.
  6. While digestive absorption is prolonged, elimination of acamprosate is rapid. The half-life of between 15 and 30 hours is therefore more representative of absorption than elimination.
  7. The pharmacokinetics of acamprosate are not affected by impaired hepatic function.

Warnings and Precautions


  • This medication should not be administered to children and the elderly.

Precautions for use

  • Acamprosate is not a treatment for the acute symptoms of alcohol withdrawal.
  • In the absence of efficacy and safety data, acamprosate is not recommended in patients under 18 years of age and in subjects over 65 years of age.
  • In the absence of efficacy and safety data, acamprosate is not recommended in patients with severe hepatic impairment (Group C of the Child-Plugh classification).
  • Since alcohol, depression and suicide are closely related, monitoring of changes in mood or behavior in patients withdrawing from acamprosate should be observed.

Abuse and addiction

  • Non-clinical studies suggest that acamprosate has little or no potential for abuse. No evidence of acamprosate dependence was found in clinical studies, thus demonstrating the absence of significant potential for acamprosate dependence.



  • There are no adequate data from the use of AOTAL in pregnant women. Animal studies have not produced any evidence of foetotoxic or teratogenic effects. AOTAL can therefore be administered during pregnancy only after careful consideration of the risk / benefit ratio when the patient cannot abstain from alcohol consumption without being treated with AOTAL and, therefore, there is a risk of fetotoxicity. or teratogenesis due to alcohol.

Feeding with milk

  • AOTAL is excreted in human milk in animals. It is not known whether acamprosate is excreted in human breast milk. There are no adequate data from the use of acamprosate in infants. Therefore, AOTAL should not be used in nursing women.
  • If a breastfeeding woman cannot abstain from alcohol consumption without being treated with acamprosate, a decision should be made to either discontinue breastfeeding or to discontinue treatment, taking into consideration the importance of treatment for the mother.


  • Animal studies do not show harmful effects on fertility. The effect of acamprosate on fertility in men and women is not known.
