CONTRAINDICATIONS FLEX is contraindicated in patients with known hypersensitivity to tizanidine.

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.

In general, symptoms resolve within one to three days following discontinuation of tizanidine and administration of appropriate therapy.
