Acamprosate comes as a delayed-release (releases the medication in the intestine) tablet to take by mouth. It is usually taken with or without food three times a day. To help you remember to take acamprosate, take it around the same times every day. Taking acamprosate with breakfast, lunch, and dinner may help you to remember all three doses. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take acamprosate exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Swallow the tablets whole; do not split, chew, or crush them.
Acamprosate helps to prevent you from drinking alcohol only as long as you are taking it. Continue to take acamprosate even if you do not think you are likely to start drinking alcohol again. Do not stop taking acamprosate without talking to your doctor.
If you drink alcohol while you are taking acamprosate, continue to take the medication and call your doctor. Acamprosate will not cause you to have an unpleasant reaction if you drink alcohol during treatment.
Take the missed dose as soon as you remember it. However, if it is almost time for the next dose, skip the missed dose and continue your regular dosing schedule. Do not take a double dose to make up for a missed one.
In case of overdose, call your local poison control center at 1-800-222-1222. If the victim has collapsed or is not breathing, call local emergency services at 911.
