   Tizanidine is a short-acting muscle relaxer. It works by blocking

   muscle tone.

   guide.

What should I discuss with my healthcare provider before taking tizanidine
(Zanaflex)?

   You should not use tizanidine if you are allergic to it, or if:
     * you also take the antidepressant fluvoxamine (Luvox); or
     * you also take the antibiotic ciprofloxacin (Cipro).

   To make sure tizanidine is safe for you, tell your doctor if you have:

   It is not known whether this medicine will harm an unborn baby. Tell
   your doctor if you are pregnant or plan to become pregnant.

   It is not known whether tizanidine passes into breast milk or if it
   could harm a nursing baby. Tell your doctor if you are breast-feeding a
   baby.

How should I take tizanidine (Zanaflex)?

   Follow all directions on your prescription label. Your doctor may
   occasionally change your dose to make sure you get the best results. Do
   not use this medicine in larger or smaller amounts or for longer than
   recommended.

   In most cases you may take tizanidine up to 3 times in one day if
   needed. Allow 6 to 8 hours to pass between doses.

   You may take tizanidine with or without food, but take it the same way
   each time. Switching between taking tizanidine with food and taking it
   without food can make the medicine less effective or cause increased
   side effects.

   Switching between tizanidine tablets and capsules can also cause
   changes in side effects or how well the medicine works.
     * Taking the tablets with food can increase your blood levels of
       tizanidine.
     * Taking the capsules with food can decrease your blood levels of
       tizanidine.

   Follow your doctor's instructions carefully. After making any changes
   in how you take tizanidine, contact your doctor if you notice any
   change in side effects or in how well the medicine works.

   Tizanidine is a short-acting medication, and its effects will be most
   noticeable between 1 and 3 hours after you take it. You should take
   tizanidine only for daily activities that require relief from muscle
   spasms.

   Do not take more than three doses (36 mg) in a 24-hour period. Too much
   of this medicine can damage your liver.

   You will need frequent blood tests to check your liver function.

   If you stop using tizanidine suddenly after long-term use, you may have
   withdrawal symptoms such as dizziness, fast heartbeats,
   tremors, and anxiety. Ask your doctor how to safely stop using this
   medicine.

   Store at room temperature away from moisture and heat.

What should I avoid while taking tizanidine (Zanaflex)?

   may be dangerous for you to have reduced muscle tone.

   Drinking alcohol with this medicine can cause side effects.

   This medicine may impair your thinking or reactions. Be careful if you
   drive or do anything that requires you to be alert. Avoid getting up
