Print Friendly, PDF & Email

Generic Name: acamprosate calcium
Product Name: Acamprosate Mylan

Indication: What Acamprosate Mylan is used for

Acamprosate Mylan is used in the treatment of 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 heartbeat 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 Mylan, 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.

Acamprosate Mylan is not recommended for use in children or elderly patients.

Acamprosate Mylan is available only with a doctor’s prescription.

There is no evidence that Acamprosate Mylan is addictive.

Action: How Acamprosate Mylan works

Acamprosate Mylan works by acting on certain chemical changes that have taken place in your brain over the time that you have been drinking alcohol.

The active ingredient in Acamprosate Mylan is acamprosate calcium. Each tablet contains 333 mg of acamprosate calcium. The tablets also contain crospovidone, microcrystalline cellulose, magnesium silicate dihydrate, sodium starch glycollate, colloidal anhydrous silica, magnesium stearate, purified talc, propylene glycol, and Eudragit L 30 D-55.

The tablets do not contain sucrose, lactose, gluten, tartrazine or any other azo dyes.
