Because the therapeutic range of tizanidine is narrow, care should be exercised if it is given to patients taking oral contraceptives. Headache Results from an open-label study and a later controlled study suggested that tizanidine might be of value in the prophylaxis of chronic daily headache. It is an a-adrenergic agonist structurally related to clonidine and acts mainly at spinal and supraspinal levels to inhibit excitatory interneurones. Oral contraceptives Mean peak plasma concentrations after a single 4-mg dose of tizanidine were 3 times greater in 15 women using an oral contraceptive containing ethinylestradiol and gestodene than in controls; the elimination half-life was not, however, significantly different.
