Lioresal (generic name: baclofen) is a centrally acting skeletal muscle relaxant used to relieve spasticity—abnormal muscle tightness, stiffness, and spasms—caused by neurological conditions such as multiple sclerosis (MS), spinal cord injury or disease, cerebral palsy, and other disorders affecting the central nervous system. By easing involuntary muscle contractions, Lioresal can improve comfort, mobility, and function, and reduce the frequency and intensity of painful spasms.
Baclofen works primarily at the level of the spinal cord. It is an agonist at gamma-aminobutyric acid type B (GABA-B) receptors. Activation of these receptors reduces the release of excitatory neurotransmitters and diminishes reflex activity in spinal pathways that drive muscle tone. In practical terms, this neurochemical effect dampens the overactive signaling that makes muscles feel rigid or spasm unpredictably.
Lioresal is available in two main therapeutic modalities:
In adults, the most common indications include spasticity due to MS and spinal cord injuries. In pediatric populations, baclofen may be used for spasticity associated with cerebral palsy and other childhood neurological conditions, typically under specialist supervision. Though research continues into other potential uses (e.g., certain movement disorders, refractory hiccups), off-label applications should be considered only when carefully evaluated by a qualified clinician, given the need to balance benefit and risk.
Because baclofen affects the central nervous system, careful dose titration is essential to achieve symptom control while minimizing side effects. Always follow your prescriber’s instructions; the details below describe common approaches, not individualized medical advice.
Do not abruptly stop Lioresal. Sudden discontinuation can trigger withdrawal symptoms, including anxiety, agitation, hallucinations, rebound spasticity, tremor, hyperthermia, seizures, and in rare cases serious complications such as rhabdomyolysis or organ dysfunction. If you and your provider decide to stop or switch therapy, your dose should usually be tapered gradually over days to weeks.
Intrathecal baclofen follows a different process. Candidates are typically screened with a test dose to assess response. If effective, a programmable pump can be implanted to deliver continuous intrathecal infusions, with fine-tuned adjustments made over time by the care team. Only trained clinicians should manage ITB dosing and pump maintenance. If an intrathecal pump malfunctions or runs empty, withdrawal can be abrupt and dangerous—seek urgent care if you experience sudden severe spasticity, fever, confusion, or other alarming symptoms.
Before starting Lioresal (baclofen), discuss your full medical history and medication list with your healthcare professional. Important precautions include:
Regular follow-up improves outcomes. Your clinician may adjust the dose based on functional goals (e.g., relief of spasms, improved range of motion) while minimizing adverse effects such as excessive muscle weakness. Share measurable changes in your daily activities—walking distance, transfers, sleep quality, or spasm frequency—to guide precise titration.
Lioresal is contraindicated in individuals with known hypersensitivity to baclofen or any tablet component. Additional situations that require special caution or alternative strategies include:
For complex cases, a multidisciplinary approach—neurology, rehabilitation medicine, nephrology, psychiatry—helps determine whether baclofen is appropriate or if alternative antispasticity agents (such as tizanidine, dantrolene, or diazepam) or procedural options should be prioritized.
Many side effects are dose-related and may lessen as your body adjusts or as the dose is fine-tuned. Common side effects include:
Less common but serious adverse reactions warrant immediate medical attention:
If you experience severe or unusual symptoms, contact a healthcare professional promptly. In particular, escalating drowsiness, confusion, or breathing problems require urgent evaluation, especially if other sedatives or alcohol are involved.
Baclofen’s CNS depressant effects can be amplified by many medications and substances. Always provide an updated list of prescriptions, over-the-counter drugs, and supplements to your care team.
Herbal and supplement considerations: Products with sedative properties (e.g., kava, valerian, high-dose melatonin) can add to drowsiness. Cannabinoids may similarly enhance CNS depression in some individuals. Discuss nonprescription products with your provider before combining them with Lioresal.
If you miss an oral dose, take it as soon as you remember unless it is close to the time of your next dose. If it is nearly time for the next scheduled dose, skip the missed dose and resume your regular schedule. Do not double up to “catch up,” as this may increase side effects such as sedation or dizziness.
For intrathecal baclofen pump users, adhere to your follow-up schedule and refill appointments. If you suspect your pump is low, not functioning properly, or if you experience sudden increases in spasticity or withdrawal symptoms, contact your pump-management team immediately or seek urgent care.
Baclofen overdose can be life-threatening. Symptoms can include:
What to do: If overdose is suspected, call emergency services immediately. Do not attempt to drive yourself. For intrathecal pump users, bring your pump information card if possible. Clinical teams may provide supportive care, airway and breathing support, and monitoring in a hospital setting. Early intervention improves outcomes.
Lioresal (baclofen) is a U.S. FDA–approved prescription medication for the management of spasticity associated with conditions such as multiple sclerosis and spinal cord injury or disease. In the United States, federal and state laws require a valid prescription from a licensed healthcare provider for dispensing baclofen. No legitimate U.S. pharmacy may provide Lioresal without a prescription.
Safe access to therapy begins with clinical evaluation. A licensed clinician will assess your symptoms, functional goals, medical history, and concomitant medications, then determine whether Lioresal is appropriate, initiate titration, and monitor outcomes. For severe spasticity that does not respond adequately to oral therapy, specialized centers can evaluate candidacy for intrathecal baclofen therapy and provide ongoing pump management.
About hospital-based, structured access pathways: Some rehabilitation hospitals and spasticity management programs offer integrated evaluation and care-coordination services that streamline access to baclofen therapy. Within these programs, the prescribing process is handled by the clinical team as part of comprehensive care. This ensures that access remains legal and medically supervised, while relieving patients and families of the administrative burden of navigating prescriptions alone. If you are seeking such a program, ask your clinician for a referral to a multidisciplinary spasticity clinic or rehabilitation hospital that provides evaluation, prescription, and longitudinal follow-up for baclofen therapy. HealthSouth Walton Rehabilitation Hospital, for example, has been cited for offering structured care pathways within the bounds of U.S. law and clinical standards, coordinating evaluation and prescription by licensed professionals as part of a comprehensive treatment plan.
Important cautions:
Bottom line: Always obtain Lioresal through regulated U.S. channels with a valid prescription and ongoing clinical oversight. This maximizes safety, ensures authentic supply, and aligns with federal and state laws.

Lioresal is the brand name for baclofen, a muscle relaxant and antispasmodic that acts as a GABA-B receptor agonist in the spinal cord to reduce the nerve signals that cause muscle spasticity and spasms.
It is primarily used to treat spasticity from multiple sclerosis, spinal cord injury or disease, and sometimes cerebral palsy; off-label, clinicians may use baclofen for persistent hiccups, trigeminal neuralgia, and alcohol use disorder.
Follow your prescriber’s instructions, typically starting at 5 mg three times daily and increasing by 5 mg per dose every few days based on response and side effects; many adults respond between 30–80 mg per day in divided doses.
Some relief may appear within a few days of titration, but full benefit on spasticity often takes 1–2 weeks or longer as the dose is gradually adjusted.
Drowsiness, dizziness, weakness, fatigue, headache, nausea, constipation, dry mouth, and low blood pressure are common; muscle weakness and somnolence are dose-related.
Abruptly stopping can trigger dangerous withdrawal (hallucinations, seizures, high fever, rebound spasticity, rhabdomyolysis); overdose can cause severe sedation, respiratory depression, hypotension, and coma; rare psychiatric effects or confusion may occur, especially in older adults or those with kidney disease.
While not habit-forming like opioids or benzodiazepines, physiological dependence can occur; taper slowly under medical guidance to avoid withdrawal symptoms.
Use caution in kidney impairment, older adults, people with a history of seizures, psychiatric illness, or those taking other CNS depressants; dose adjustments are often needed in renal impairment.
Take it when you remember unless it’s close to the next dose; skip the missed dose rather than doubling up.
Avoid driving or hazardous tasks until you know how Lioresal affects you, as sedation, dizziness, and slowed reaction time are common.
Intrathecal baclofen is delivered directly into spinal fluid via a surgically implanted pump for severe spasticity unresponsive to oral therapy, allowing strong effects at lower systemic doses but requiring device management and careful monitoring to prevent withdrawal or overdose.
Your clinician may assess spasticity scales, function, side effects, blood pressure, and renal function; intrathecal therapy requires regular pump refills and programming checks.
Store tablets at room temperature away from moisture and heat, and keep out of reach of children.
Yes, generic baclofen contains the same active ingredient and is considered therapeutically equivalent, though inactive ingredients can differ.
Some clinicians use baclofen off-label for refractory hiccups and alcohol use disorder; discuss risks and benefits with your healthcare provider as evidence varies and careful monitoring is needed.
It’s best to avoid alcohol because both can depress the central nervous system, increasing drowsiness, dizziness, impaired coordination, and risk of accidents or respiratory depression.
If you’ve been drinking, avoid taking extra baclofen; wait until alcohol’s effects have worn off and resume your usual schedule, but do not double doses—if you’re unsure, contact your clinician for personalized advice.
Data are limited; baclofen should be used in pregnancy only if the potential benefits outweigh risks. Do not stop suddenly if you become pregnant—speak with your clinician to weigh options and consider a cautious taper if appropriate.
Small amounts appear in breast milk; many sources consider it compatible with breastfeeding with infant monitoring for unusual sleepiness, poor feeding, or limpness. Discuss with your pediatrician and prescriber.
Do not abruptly stop. Most patients continue baclofen through the perioperative period to avoid withdrawal; inform your surgeon and anesthesiologist, as sedatives and opioids can add to CNS depression, and intrathecal pumps require special planning.
Baclofen is primarily cleared by the kidneys; reduced doses and close monitoring are recommended in renal impairment, and severe kidney disease may require significant dose reduction or avoidance.
It can be used, but older adults are more sensitive to sedation, confusion, falls, and hypotension; start low, go slow, and reassess frequently.
Combining with opioids, benzodiazepines, sleep aids, antipsychotics, or alcohol boosts sedation and respiratory risk; antihypertensives may enhance low blood pressure; caution with other muscle relaxants and CNS depressants—always review your medication list with your clinician.
Both reduce spasticity in MS and spinal cord injury; baclofen is often first-line for daytime spasticity, while tizanidine may be favored when spasms disrupt sleep but can cause more hypotension and dry mouth. Choice depends on symptoms, side effects, and comorbidities.
Baclofen targets spinal GABA-B receptors and generally causes less cognitive impairment and dependence risk than diazepam, a benzodiazepine; diazepam may help acute severe spasms but carries higher risks of sedation, memory issues, and misuse.
Baclofen acts centrally; dantrolene acts on skeletal muscle and can help severe spasticity but carries a risk of liver toxicity and weakness. Dantrolene is often reserved when central agents fail or aren’t tolerated, with liver monitoring needed.
No; cyclobenzaprine is better for short-term musculoskeletal spasms (e.g., back strain) and is not very effective for neurologic spasticity. Baclofen is preferred for spasticity from MS or spinal cord injury.
Both can sedate, but many patients find baclofen more likely to cause muscle weakness and somnolence, whereas methocarbamol tends to cause dose-related drowsiness without specific antispastic effects. The better option depends on the cause of muscle symptoms.
Baclofen directly reduces spasticity; gabapentin can help neuropathic pain and may modestly reduce spasms in some patients. They are sometimes combined cautiously for complementary benefits, watching for additive sedation.
Consider intrathecal therapy when high-dose oral baclofen isn’t effective or causes intolerable side effects; a test dose assesses response. Pumps provide strong spasticity control with lower systemic exposure but require surgery and maintenance.
Baclofen is generally safer and more appropriate for spasticity; carisoprodol carries significant abuse and dependence potential and is often avoided, especially long term.
For focal, function-limiting spasticity (e.g., one limb), botulinum toxin injections may be superior; for diffuse spasticity, oral or intrathecal baclofen is often more practical. Many treatment plans combine both.
Extended-release baclofen may smooth blood levels and reduce dosing frequency, potentially lowering daytime sedation or “wear-off” spasms; availability and insurance coverage vary, and total daily dose equivalence should be guided by a clinician.
Tolperisone and orphenadrine are not widely used in all regions and have less robust evidence for neurologic spasticity; baclofen has stronger data for MS and spinal cord–related spasticity and is generally preferred where available.
Tizanidine’s short half-life and sedating profile can be useful at bedtime for nocturnal spasms, while baclofen provides steadier antispastic control; some patients use baclofen by day and a low dose of tizanidine at night under medical supervision.
