What should you know about tizanidine for headache?

Tizanidine reduces muscle spasm through effects on the nervous system. A prescriber may consider it when neck or jaw muscle tightness contributes to a headache, or when other approaches have not suited the person. It is not a general painkiller and does not treat every cause of headache. Sleepiness, dizziness, dry mouth, weakness and a fall in blood pressure are possible. Alcohol, sedatives and some other medicines can intensify these effects; the prescriber needs a complete medication list.

Take it only in the dose and schedule prescribed, and do not drive or operate machinery until you know how it affects you. Rise slowly if you feel dizzy. Do not stop regular use suddenly without medical advice, because the body may react with a rapid pulse or raised blood pressure. Keep a headache diary with timing, triggers, neck symptoms, dose and response. Hydration, regular meals and sleep may support recovery, but a new or changing pattern needs assessment.

Seek emergency care for a sudden severe headache, new weakness, trouble speaking, confusion, seizure, fainting, fever with a stiff neck, or a headache after a significant head injury. Contact your prescriber urgently for extreme sleepiness, faintness, slow heartbeat, yellowing of the skin or eyes, or an allergic reaction. Repeated headaches, vomiting, or headaches that are becoming more frequent also warrant review.

Ask why tizanidine is being considered, how long to use it, which medicines or drinks to avoid, how to taper it, and what warning symptoms should prompt a call.
