    How It Works

    The muscle-relaxing effects of these medicines are most likely the result of their ability to depress the central nervous system.

    Why It Is Used

    Muscle relaxants can be helpful when severe muscle spasms follow the start of low back pain.

    Muscle relaxants are not recommended for use by pregnant women, older adults, or people who have depression or a history of drug or alcohol addiction.

    How Well It Works

    Muscle relaxants may improve acute or chronic low back pain, muscle tension, and mobility. But side effects are common.1, 2

    Side Effects

    Possible side effects of muscle relaxants include:

    See Drug Reference for a full list of side effects. (Drug Reference is not available in all systems.)

    What To Think About

    Muscle relaxant medicines work best when they are taken before bedtime. They should not be used by a person who needs to drive or operate machinery.

    Use of muscle relaxants is restricted to short-term use to avoid addiction.
