What happens if I overdose (Zanaflex)?
Seek emergency medical attention if you think you have used too much of this medicine.
Overdose symptoms may include drowsiness, confusion, slow heart rate, shallow breathing, feeling light-headed, fainting, or coma.
What should I avoid while taking tizanidine (Zanaflex)?
Tizanidine can cause side effects that may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be awake and alert. Dizziness is most likely to occur when you rise from a sitting or lying position. Get up slowly to prevent dizziness and a possible fall.
Do not use tizanidine at a time when muscle tone is needed to assure safe balance and movement for certain activities. In some situations, it may endanger your physical safety to be in a state of reduced muscle tone.
Cold or allergy medicine, narcotic pain medicine, sleeping pills, other muscle relaxers, and medicine for seizures, depression or anxiety can add to sleepiness caused by tizanidine. Tell your doctor if you need to use any of these other medicines together with tizanidine.
Avoid drinking alcohol. It can increase some of the side effects of tizanidine.
