Treatment Options for Addiction and Abuse

Flexeril addiction treatment depends on each individual’s situation. No single treatment works the same for everyone.

Common treatment options include:

Inpatient treatment includes entering a residential facility where clients live full-time during recovery. The stay can be as short as a few weeks, 30 days, or longer if the case is severe. Residential treatment programs use a combination of approaches such as medical detox, individual counseling, group therapy, and 12-step programs.

Outpatient treatment is another option that offers the same types of therapies as residential rehab. During this type of treatment, clients live at home. Outpatient treatment is a good choice for anyone who wants to attend treatment while continuing to work, attend school, or meet family obligations.

Don’t hesitate to reach out for help if you suspect the presence of a Flexeril use disorder. Recovery is possible.
