Drug Class: Central Acting Skeletal Muscle Relaxant / GABA-B Agonist | Form: Oral Tablet | Prescription Status: Prescription Only (Rx) — DRAP Registered
What is Baclin 20mg Tablet? Baclin 20mg contains Baclofen — a centrally acting muscle relaxant that works directly on the spinal cord to reduce severe muscle spasticity caused by neurological conditions. Unlike peripheral muscle relaxants, Baclofen acts on GABA-B receptors in the spinal cord — reducing the excessive nerve signals responsible for painful muscle spasms, stiffness, and involuntary contractions. It is prescribed for patients with significant spasticity that impairs mobility, causes pain, or interferes with daily activities. Baclofen must be started at a low dose and increased very gradually — and must never be stopped suddenly as abrupt withdrawal can be life-threatening.
What is Baclin 20mg Used For?
- Multiple sclerosis — painful muscle spasticity and stiffness (ایم ایس میں پٹھوں کی اکڑن)
- Spinal cord injury — muscle spasms and rigidity following injury (ریڑھ کی ہڈی کی چوٹ میں اکڑن)
- Cerebral palsy — muscle stiffness and spasticity in neurological disability (دماغی فالج میں پٹھوں کی سختی)
- Stroke-related spasticity — muscle stiffness following brain stroke (فالج کے بعد پٹھوں کی اکڑن)
- Traumatic brain injury — spasticity management under neurological supervision
- Severe painful muscle spasms from other neurological conditions (شدید پٹھوں کا کھنچاؤ)
How Does it Work? Baclofen is a structural analogue of GABA — the brain and spinal cord's main inhibitory neurotransmitter. It selectively activates GABA-B receptors in the spinal cord — reducing the release of excitatory neurotransmitters that cause abnormal muscle activity. This reduces the frequency and severity of muscle spasms, decreases muscle tone, and relieves the pain associated with spasticity. Unlike older muscle relaxants, Baclofen acts specifically at the spinal level — providing targeted relief of spasticity without completely blocking voluntary muscle function when used at appropriate doses.
Dosage and Administration
⚠️ Always start at lowest dose and increase very slowly. Never stop suddenly — abrupt withdrawal causes dangerous seizures, hallucinations, and life-threatening complications. Dose must be reduced gradually under strict doctor supervision. Causes significant drowsiness — avoid driving especially when starting or changing dose.
| Indication | Usual Starting Dose | Maintenance Dose | Frequency |
|---|---|---|---|
| Spasticity — all neurological causes | 5mg three times daily | Up to 80mg daily | Three times daily — increased slowly |
| Elderly patients | 5mg twice daily initially | Lower maintenance dose | Increased very cautiously |

Who Should NOT Take Baclin 20mg?
- Allergy to Baclofen or any component of the tablet
- Epilepsy or history of seizures — Baclofen lowers seizure threshold
- Peptic ulcer disease — Baclofen may worsen stomach ulcers
- Severe kidney impairment — Baclofen accumulates dangerously
- Psychiatric disorders — psychosis, schizophrenia, or severe depression
- Parkinson's disease — Baclofen may worsen symptoms
- Pregnancy and breastfeeding — consult neurologist before use
- Children under 12 years unless specifically directed by specialist
- Cerebrovascular disease — stroke history requires careful specialist assessment
Side Effects
Common: Significant drowsiness and sedation (زیادہ نیند آنا), dizziness especially on standing, muscle weakness, nausea, dry mouth, fatigue, mild confusion — particularly in elderly patients. Drowsiness usually reduces after dose stabilisation.
Serious — Stop and seek emergency help immediately: Seizures or convulsions — particularly if dose missed or stopped suddenly (مرگی کے دورے — فوری ہسپتال جائیں), severe confusion or hallucinations (وہم اور خیالی باتیں — فوری مدد لیں), sudden severe muscle weakness causing inability to move, respiratory depression — very slow or shallow breathing especially at high doses, severe psychiatric symptoms including suicidal thoughts (فوری ڈاکٹر کو بتائیں), significant low blood pressure with fainting, signs of Baclofen withdrawal — high fever, severe agitation, muscle rigidity if stopped abruptly.
Drug Interactions
| Medicine | Interaction |
|---|---|
| CNS depressants / sedatives / sleeping tablets | Severely additive sedation and respiratory depression — use with extreme caution |
| Antihypertensives | Baclofen increases blood pressure lowering effect — increased hypotension risk |
| Tricyclic antidepressants (Amitriptyline) | Increased muscle weakness and sedation |
| Antiepileptics | Additive CNS depression — increased sedation and seizure threshold lowering |
| Lithium | Baclofen may worsen hyperkinetic symptoms in Lithium-treated patients |
| Levodopa / Carbidopa | Combination may cause confusion and hallucinations — use with caution |
| Morphine / Opioid pain medicines | Severely increased sedation and respiratory depression risk — use with extreme caution |
| Alcohol (شراب) | Severely increases CNS and respiratory depression — avoid completely |
Storage: Store below 25°C in a cool, dry place. Protect from moisture and direct sunlight. Keep out of reach of children (بچوں کی پہنچ سے دور رکھیں). Do not use after expiry date.
FAQs
Q: Can Baclin 20mg be stopped suddenly if side effects become too difficult? Never stop suddenly under any circumstances — abrupt Baclofen withdrawal causes life-threatening seizures, severe hallucinations, and dangerous rebound spasticity. Always consult your neurologist for a very slow and carefully supervised dose reduction plan.
Q: Why does Baclin cause so much drowsiness compared to other muscle relaxants? Baclofen acts directly on the central nervous system at the spinal cord level — CNS depression and drowsiness are expected effects, particularly when starting or increasing dose. Drowsiness usually improves significantly once the dose stabilises over several weeks.
Q: Can Baclin 20mg completely eliminate muscle spasms in multiple sclerosis? Baclofen significantly reduces spasm frequency and severity but may not eliminate them completely — the goal of therapy is meaningful improvement in comfort and mobility rather than complete elimination, balancing benefit against acceptable side effects.
