What this medicine is used for
The name of your medicine is APO-Acamprosate Enteric Coated Tablets. It contains the
active ingredient acamprosate calcium.
It is used to treat alcohol dependence. It helps people who are dependent on alcohol
to abstain from drinking alcoholic beverages.
Alcohol dependence is an illness that can and should be treated. Drinking too much
alcohol may harm your health and cause physical, psychological and social problems.
If this happens to you, your doctor may advise you to stop drinking alcohol altogether.
If you drink too much alcohol, your body and nervous system adapt to its effects.
When you suddenly stop drinking, you may experience some unpleasant symptoms (known
as alcohol withdrawal syndrome or the "shakes"), which can last up to 2 weeks.
During alcohol withdrawal, you may feel shaky, have an upset stomach, a fast heart
beat and high blood pressure. You may also feel anxious, down, or be in a bad mood.
Sometimes, you may see things that are not there, or suffer from a headache or not
be able to sleep.
If these symptoms are severe, you may need observation in hospital.
After going through this difficult period, your doctor will encourage you to live
without alcohol through counselling. Acamprosate, in combination with counselling
from a general practitioner, psychiatrist, psychologist, or a drug and alcohol counsellor,
will help you to stop yourself from starting to drink again.
Ask your doctor if you have any questions about why this medicine has been prescribed
for you. Your doctor may have prescribed this medicine for another reason.
This medicine is available only with a doctor's prescription.
How it works
This medicine works by acting on certain chemical changes that have taken place in
your brain over the time that you have been drinking alcohol.
