Quick Overview

Baclofen is a prescription medicine that helps reduce muscle spasticity. It primarily relaxes skeletal (striated) muscles by acting on the spinal cord to dampen overactive nerve signals.

What Baclofen Is Used For

Baclofen is most often prescribed for conditions where muscles are tight, cramping, or spasming because of nerve problems. It may help if you experience:

  • Muscle rigidity and painful spasms after spinal cord injury
  • Spasticity related to multiple sclerosis
  • Muscle clonus and cramping associated with other neurological disorders

By reducing involuntary muscle contractions, Baclofen can improve comfort, mobility, and function in daily activities.

How to Take Baclofen (Dosage and Direction)

Use Baclofen exactly as prescribed. Do not change your dose or stop suddenly unless your prescriber guides you.

  • Typical adult starting dose: 5 mg by mouth three times a day.
  • Dose increases: your clinician may raise the total daily dose by 15 mg every 3 days as tolerated.
  • Usual maximum: 80 mg per day in divided doses.
  • Take with water and swallow whole. Food is optional.

Strengths available on this site typically include 25 mg and 10 mg. Your pharmacy may offer other strengths; your clinician will choose what best fits your titration plan.

Important: If therapy needs to be stopped, your dose should be tapered to avoid withdrawal symptoms. See Precautions and Warnings.

Precautions and Warnings

Tell your prescriber about your medical history before starting Baclofen, including:

  • Kidney disease or reduced kidney function
  • Seizure disorders or history of epilepsy
  • History of stroke or blood clots
  • Any prior allergic reactions to medicines, foods, dyes, or preservatives
  • Pregnancy, plans to become pregnant, or breastfeeding

Safety tips:

  • Baclofen may cause dizziness or drowsiness, especially when starting or changing doses. Avoid driving or operating machinery until you know how you respond.
  • Stand up slowly from sitting or lying positions to reduce the chance of lightheadedness or falls.
  • Do not stop Baclofen abruptly. Sudden discontinuation can cause severe symptoms such as agitation, hallucinations, seizures, high fever, and rebound spasticity. Your dose must be reduced gradually under medical supervision.

Who Should Not Use Baclofen (Contraindications)

  • People with a known hypersensitivity or allergy to Baclofen
  • Use with great caution or avoid if your clinician advises against it due to kidney impairment, seizure disorders, or certain neurological conditions

If any of these apply to you, discuss alternatives in Similar and Alternative Medicines.

Possible Side Effects

Call your clinician right away or seek urgent care if you notice severe reactions such as:

  • Allergic symptoms: rash, itching, hives, swelling of face/lips/tongue, trouble breathing
  • Hallucinations, profound confusion, or seizures
  • Very low blood pressure, chest pain, or trouble breathing
  • Severe vomiting or persistent constipation
  • Urinary retention or markedly increased urinary frequency

Other effects that are usually mild but should be reported if persistent or bothersome:

  • Drowsiness, dizziness, or weakness
  • Headache or insomnia
  • Nausea or mild gastrointestinal upset
  • Confusion or fatigue

Risk may be greater when combined with other sedating substances. See Drug and Alcohol Interactions.

Drug and Alcohol Interactions

Baclofen can increase sedation and impair coordination when taken with other central nervous system depressants. Be especially cautious with:

  • Alcohol and recreational sedatives
  • Opioid pain relievers such as oxycodone, codeine, or tramadol
  • Sleep medications and sedative-hypnotics
  • Antihistamines that cause drowsiness
  • Medications for mood or anxiety, including tricyclic antidepressants and benzodiazepines
  • Monoamine oxidase inhibitors (MAOIs), which may worsen low blood pressure or CNS depression
  • Phenobarbital and other barbiturates

Always provide your clinician and pharmacist with a full list of all prescription drugs, OTC products, and supplements you take.

Missed Dose and Overdose

Missed dose: Take it when remembered unless it is nearly time for the next dose. If so, skip and resume your regular schedule. Do not double up.

Overdose: If you or someone else may have taken too much, call Poison Control (in the USA: 1-800-222-1222) or go to the nearest emergency department immediately. Symptoms may include extreme drowsiness, respiratory depression, confusion, seizures, or loss of consciousness.

Storage

  • Store at room temperature, 15 to 30 C (59 to 86 F).
  • Keep tightly closed in the original container and out of reach of children and pets.
  • Protect from excess moisture and heat.
