Tizanidine - generic Zanaflex - is used to treat muscle spasms. Tizanidine is a
short-acting drug for the management of spasticity. Because of the short
duration of effect, treatment with Zanaflex should be reserved for
those daily activities and times when relief of spasticity is most
important
A single oral dose of 8 mg of Zanaflex reduces muscle tone in patients
with spasticity for a period of several hours. The effect peaks at
approximately 1 to 2 hours and dissipates between 3 to 6 hours. Effects
are dose-related.
SIDE EFFECTS: Nausea, drowsiness, dizziness, constipation,
unusual weakness or dry mouth might occur. If these side effects
continue or are bothersome, notify your doctor. To minimize dizziness,
stand up slowly when arising from a sitting or lying position. Notify
your doctor if you develop: yellowing skin or eyes, stomach pain,
vomiting, hallucinations. Very unlikely but report: vision or hearing
changes, urinary frequency or burning, slow or irregular heartbeat,
black stool. A serious allergic reaction to this drug is unlikely, but
seek immediate medical attention if it occurs. Symptoms of a serious
allergic reaction include: rash, itching, severe dizziness, trouble
breathing. |
