Baclofen basics
Baclofen is a prescription-only medication used to reduce spasticity. It works primarily in the spinal cord by activating GABA-B receptors, which suppress excessive nerve signals that lead to involuntary muscle tightness and spasms.
It is most commonly prescribed for symptoms where central nervous system overactivity causes troublesome muscle tone and pain.
Who might benefit from this
Your doctor may recommend baclofen for the following situations:
- Spasticity and muscle stiffness after spinal cord injury
- Muscle clonus and frequent spasms
- Cramping and painful contractions of skeletal muscle
- Spasticity associated with multiple sclerosis
Whether baclofen is appropriate depends on the underlying diagnosis, other medical conditions, and treatment goals. Discuss suitability as advised by your prescriber.
How to administer baclofen
Observe your prescription without deviation. Do not augment the dose or the dosing frequency without advice from a medical professional. Do not use for longer than prescribed.
- Administration: swallow tablets with water. Food is not usually required but follow any specific instructions given by your clinician.
- Adults often start at 5 mg, administered three times per day.
- Titration: your prescriber may increase the total daily dose gradually, for example by around 15 mg every 3 days, adjusting each dose by small increments based on effect and tolerance.
- Usual upper limit: many patients do not exceed 80 mg per day in divided doses unless a specialist advises otherwise.

Alternative drugs and related therapies

- Tizanidine: another central muscle relaxant; may cause hypotension and drowsiness and sometimes requires liver tracking and monitoring of performance.
- Diazepam: a benzodiazepine used for short term relief of muscle spasm; has sedative effects and latent potential for dependence.
- Dantrolene: works directly on muscle fibers; long term use can be associated with liver toxicity.
- Gabapentin or pregabalin: often used as adjuncts when neuropathic pain is present.
- Botulinum toxin injections: useful for focal spasticity affecting specific muscles.
- Intrathecal baclofen delivered by implantable pump: option for severe refractory spasticity managed by specialists.
