How alcohol misuse is treated depends on how much alcohol a person is drinking. Treatment options include:
There are two main types of medicines to help people stop drinking. The first is to help stop withdrawal symptoms, and is given in reducing doses over a short period of time. The most common of these medicines is chlordiazapoxide (Librium).
The second is a medication to reduce any urge you may have to drink. The most common medications used for this are acamprosate and naltrexone. These are both given at a fixed dose, and you'll usually be on them for 6 to 12 months.
