Drug Class: Skeletal Muscle Relaxant | Form: Oral Tablet | Prescription Status: Prescription Only (Rx) — DRAP Registered
What is Myolax 4mg Tablet? Myolax 4mg contains Thiocolchicoside — a muscle relaxant that works on the central nervous system to relieve painful muscle spasms, rigidity, and involuntary contractions. It is prescribed for short-term management of acute muscle spasm caused by spinal disorders, trauma, and neurological conditions. Thiocolchicoside is typically used for a maximum of 7 consecutive days — it is not suitable for long-term use. It is often prescribed alongside pain medicines or physiotherapy for better overall relief.
What is Myolax 4mg Used For?
- Painful muscle spasms from spinal disorders — neck and back (گردن اور کمر کی اکڑن)
- Acute low back pain with muscle rigidity (کمر درد اور پٹھوں کی سختی)
- Post-traumatic muscle contractions after injury (چوٹ کے بعد پٹھوں کا کھنچاؤ)
- Muscle stiffness associated with neurological conditions (اعصابی بیماریوں میں پٹھوں کی سختی)
- Cervical spondylosis — neck stiffness and spasm (گردن کی ہڈی کا درد)
How Does it Work? Thiocolchicoside acts on GABA-A and glycine receptors in the central nervous system — increasing inhibitory signals that reduce abnormal muscle activity. This relaxes overactive, spasming muscles without causing significant sedation at therapeutic doses, allowing patients to remain functional during treatment.
