What CLOFEN is used for
CLOFEN belongs to a group of medicines called muscle relaxants.
This medicine is used to reduce stiffness and/or spasms in your muscles.
CLOFEN is used to control muscle spasms in conditions such as:

CLOFEN may be used alone, or in combination with other medicines, to treat your condition.
Ask your doctor if you have any questions about why this medicine has been prescribed for you. Your doctor may have prescribed it for another reason.
