Baclofen is a prescription medication used to treat muscle spasms and muscle stiffness caused by conditions such as multiple sclerosis or spinal cord injuries. Although it is not typically considered to be an addictive drug, it can be habit-forming if misused or abused. It is possible for individuals to become dependent on baclofen if they use it regularly or in higher doses than prescribed. However, with proper medical supervision and treatment, it is possible to overcome a dependence on baclofen.
