Tizanidine Overdose

As with most medicines, it is possible to overdose on tizanidine (Zanaflex). Some of the possible symptoms of an overdose include low blood pressure, lethargy, confusion, and irregular breathing. Taking too much tizanidine can be dangerous, possibly even resulting in death. Seek immediate medical attention if you think you may have taken an overdose.

Can You Take Too Much Tizanidine?
