Zanaflex

Brand name:

Zanaflex

Pronounced: ZAN-uh-flecks
Generic name: Tizanidine

Why is Zanaflex prescribed?

Zanaflex relaxes the tense, rigid muscles caused by spasticity. It is prescribed for people with multiple sclerosis, spinal cord injuries, and other disorders that produce protracted muscles spasms. The effect of the drug peaks 1 to 2 hours after each dose and is gone within 3 to 6 hours, so it's best to schedule doses for shortly before the daily activities when relief of spasticity is most important.

Most important fact about Zanaflex

Zanaflex causes drowsiness in almost half the people who use it. It also tends to reduce blood pressure in many people, frequently leading to dizziness and light-headedness. The likelihood of significant drowsiness increases when Zanaflex is combined with other spasticity drugs, such as Lioresal, Klonopin, and Valium. When taking Zanaflex, always be cautious about driving or operating dangerous machinery.

How should you take Zanaflex?

Take Zanaflex exactly as directed. The danger of side effects increases with the size of the dose.

--If you miss a dose...

Doses should be taken only as needed. Allow 6 to 8 hours between doses. Take no more than 3 a day. Never double the dose.

--Storage instructions...

Store at room temperature.

What side effects may occur?

Side effects cannot be anticipated. If any develop or change in intensity, tell your doctor as soon as possible. Only your doctor can determine if it is safe to continue using Zanaflex.

• More common side effects may include:
  Abnormal movements, blurred vision, constipation, dizziness, drowsiness, dry mouth, flu-like symptoms, frequent urination, low blood pressure, nervousness, runny nose, slow heartbeat, sore throat, speech disorders, urinary and other infections, vomiting, weakness or fatigue

Why should Zanaflex not be prescribed?

You'll need to avoid Zanaflex if it gives you an allergic reaction.

Special warnings about Zanaflex

Researchers have little information on the long-term consequences of using Zanaflex in single doses of more than 8 milligrams, or in total amounts of more than 24 milligrams a day. If you require a higher dosage, previously unrecognized side effects could possibly appear.

Remember that Zanaflex can cause low blood pressure and should be used with caution if you are taking blood pressure medication. Be cautious, too, when first standing up. Dizziness and light-headedness are especially likely at that time.
