Educational Pearls:

• Baclofen is used to treat muscle spasms or spasticity.
• Baclofen comes in two forms: oral and intrathecal
• Withdrawal is much more common with those receiving intrathecal administration from a Baclofen pump, which is typically spinal cord patients
• Withdrawal symptoms usually start within 1-3 days after stopping baclofen
• Symptoms include altered mental status, muscle rigidity, and fevers, which can mimic other severe illnesses
• It is nearly impossible to reverse withdrawal symptoms with oral baclofen if a patient is receiving it intrathecally, so solving the pump problem is key
