Mechanism Of Action | Tizanidine is an agonist at centrally acting alpha2- receptor sites and presumably reduces spasticity by increasing presynaptic inhibition of motor neurons. |
INDICATIONS | Tizanidine is a short-acting drug for the acute and intermittent management of increased muscle tone associated with spasticity. FLEX is indicated for the treatment of spasticity associated with multiple sclerosis or spinal cord injury or disease |
CONTRAINDICATIONS | FLEX is contraindicated in patients with known hypersensitivity to tizanidine. |
Side EFFECTS | The most common side effects, that may go away as the body adjusts to the medication and do not require medical attention unless they continue for more than two weeks or are bothersome, include drowsiness, fatigue, dizziness, dry mouth, nausea, gastro-intestinal disturbances, blurred vision, and hypotension. Bradycardia, insomnia, hallucinations, and rarely acute hepatitis, are also reported |
WARNINGS | THIS MEDICINE MAY CAUSE DROWSINESS. Using this medicine alone, with other medicines, or with alcohol may lessen the ability to drive or to perform other potentially dangerous tasks. Caution should be exercised when FLEX is given to elderly, and patients with renal and hepatic impairment. The liver function should be monitored monthly for first 4 months during treatment, articularly, in those who develop unexplained nausea, anorexia or fatigue. Concomitant administration of drugs that prolong QT interval should be avoided during treatment with |
DRUG INTERACTIONS | Oral contraceptives may slow the release of tizanidine from the body; therefore, the dose level of tizanidine can be reduced in women using birth control pills. Tizanidine will add to the effects of alcohol and other central nervous system (CNS) depressants (such as antihistamines, sedatives, tranquilizers, prescription pain medications, seizure medications, and other muscle relaxants), possibly causing drowsiness.

The dose becomes 1-2 tablets of FLEX-4 mg every 6 to 8 hours. The total daily dose should not exceed 36 mg. Children- not recommended. |
OVERDOSE | Should overdosage occur, the most common symptoms involve depressed consciousness (somnolence, stupor, or coma), depressed cardiovascular function (bradycardia, hypotension), and depressed respiratory function (respiratory depression or failure). The treatment includes the basic steps to ensure the adequacy of an airway and the monitoring of cardiovascular and respiratory systems. In general, symptoms resolve within one to three days following discontinuation of tizanidine and administration of appropriate therapy. |
