Tizanidine Patient Tips

How it works

Tizanidine relaxes muscles by dampening down nerve impulses that are sent from spasming muscles to the brain.

Upsides

  • Effective at relaxing muscles (reduces muscles spasms).

Downsides

If you are between the ages of 18 and 60, take no other medication or have no other medical conditions, side effects you are more likely to experience include:

  • Low blood pressure, drowsiness, dizziness, energy loss, hallucinations, and a dry mouth.
  • May affect a person's ability to drive or operate machinery. Avoid alcohol.
  • May cause withdrawal symptoms if stopped abruptly after regular extended dosing (decrease dose slowly under a doctor's advice).

Notes: In general, seniors or children, people with certain medical conditions (such as liver or kidney problems, heart disease, diabetes, seizures) or people who take other medications are more at risk of developing a wider range of side effects.

Bottom Line

Tizanadine is an effective muscle relaxant; however, it causes sedation and has a high risk of liver toxicity, so monitoring of liver enzymes is required.

Tips

  • Capsules may be opened and the contents sprinkled on food.
  • Taking with food increases absorption by 20% but slows time for effect. Can be taken with or without food, but should be dosed consistently (either with or without food).
  • Effects are dose-related (the bigger the dose, the stronger the effect, but the more noticeable any side effects are).

Response and Effectiveness

Effect peaks within 1-2 hours and diminishes within 3 to 6 hours. may be dosed on an "as needed" basis (during times when muscle spasms are most severe).
