  • Avoid alcohol beverages and foods that contain alcohol during this time.
  • Drinking alcohol during pregnancy can harm your baby and lead to foetal alcohol syndrome which causes birth defects, learning disabilities, and growth retardation.

  • Remember that your medications are prescribed to you for your individual medical needs. Do not share medications with others.
  • Your doctor may suggest laboratory tests and kidney function tests to help monitor your progress and check for side effects. During this time it's important that you keep all your medical appointments and attend all your counselling and support group sessions.
  • Acamprosate should be stored at room temperature and away from light and moisture.
  • Store Acamprosate away from sunlight and moisture. Keep your medications away from children and pets.

Avoid storing medications in the bathroom where they can be easily reached.

Interactions and overdose

  • Discuss all possible drug interactions with your doctor or pharmacist before taking Acamprosate. Inform your doctor or pharmacist of all prescription, non-prescription, or herbal medications you are using. This will help prevent negative side effects from drug interaction.
  • Don't start, stop, or alter a dosage without the consent of your doctor. Doing so can hinder the effectiveness of the drug.
  • If you've missed a dose, take it as soon as you remember. If you are closer to your next dose, skip the one you missed and resume your usual dosage schedule. Do not try to double doses to catch up as this can lead to overdose.
  • If you suspect drug overdose, contact your nearest poison control centre or emergency room right away. Symptoms of Acamprosate overdose may include persistent diarrhoea.
