Clinical Overview
Tizanidine Tablets (2mg) is an oral centrally acting imidazoline-derivative alpha-2 adrenergic receptor agonist on the WHO Model List framework. It binds to presynaptic alpha-2 adrenergic receptors in the spinal cord, reducing facilitation of spinal motor neurons and suppressing polysynaptic reflexes, relieving muscle hypertonia and spasms without causing significant muscle weakness. Indicated for painful muscle spasms associated with spinal disorders, torticollis, lumbago, and spasticity in multiple sclerosis or spinal cord injury.

Usage Guidelines
Take orally starting with 2 mg up to three times daily with water, with or without food. Can be titrated up to 4 mg to 8 mg per dose (maximum 24-36 mg daily). Be consistent with food timing (food increases bioavailability).
General Administration Advice: Adhere strictly to the prescribed dosage, frequency, and treatment course. For oral medications, swallow with sufficient water. Never stop antibiotics, psychiatric medications, or antihypertensives abruptly without clinical direction.
Possible Side Effects
Common: Somnolence, dry mouth, dizziness, fatigue, asthenia, hypotension, bradycardia. Rare/Severe: Severe hypotension, syncope, QT prolongation, and drug-induced hepatotoxicity (transaminase elevations in ~5%).
*Note: Individual physiological responses vary. While many patients experience few or no side effects, notify your treating physician if adverse reactions persist or if hypersensitivity (angioedema, skin rash, dyspnea) occurs.
Precautions & Warnings
Black Box Contraindication: Strictly contraindicated with potent CYP1A2 inhibitors (fluvoxamine, ciprofloxacin) due to massive increases in tizanidine plasma concentrations causing profound hypotension, bradycardia, and coma. Monitor liver enzymes at baseline, 1, 3, and 6 months. Causes marked sedation; do not drive.
