The duration of alcohol addiction treatment can vary depending on the individual's needs and the severity of their addiction. The first source [1] provides information on a medication called ALCOHOL, which is used to treat alcohol dependence. However, it does not mention the duration of treatment.

According to the American Addiction Centers [2], the length of alcohol rehab can range from 30 to 90 days, with some programs lasting up to a year. The duration of treatment depends on the individual's specific needs and the level of care required. Inpatient programs typically last longer than outpatient programs, as they provide more intensive treatment and support.

Addiction Center [3] notes that the length of treatment can also depend on the type of treatment program. For example, detoxification typically lasts 3-7 days, while residential treatment can last up to 90 days. Outpatient treatment can last several months, and aftercare programs can continue for years.

In conclusion, the duration of alcohol addiction treatment varies depending on the individual's needs and the severity of their addiction. It can range from a few days to several months or even years. The type of treatment program and level of care required can also impact the length of treatment.
