Generic name: Tizanidine ,TIZANIDINE HCL
Why is TIZANIDINE HCL prescribed?

TIZANIDINE HCL 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 TIZANIDINE HCL

TIZANIDINE HCL 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 TIZANIDINE HCL is combined with other spasticity drugs, such as Lioresal, Klonopin, and Valium. When taking TIZANIDINE HCL, always be cautious about driving or operating dangerous machinery.

Special warnings about TIZANIDINE HCL

Researchers have little information on the long-term consequences of using TIZANIDINE HCL 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 TIZANIDINE HCL 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.

TIZANIDINE HCL has been known to cause liver injury in a few patients. If you have a liver condition, make sure the doctor knows about it. Alert your doctor immediately if you develop warning signs of a liver problem such as loss of appetite, nausea, vomiting, or yellow skin or eyes.

You'll need a reduced dose of TIZANIDINE HCL if you have a kidney problem. Be sure to inform the doctor about your condition, and be quick to report side effects such as dry mouth, drowsiness, dizziness, and weakness. They could be signs that your dose is too high.

Use TIZANIDINE HCL with caution if spasticity helps you maintain your posture and balance while walking, or helps to increase other functions.

Although there are no reports of eye damage from TIZANIDINE HCL, it has occurred in animal tests. Be sure to report any vision problems to your doctor.

Possible food and drug interactions when taking TIZANIDINE HCL

Oral contraceptives tend to boost the amount of TIZANIDINE HCL in the system. If you are using an oral contraceptive, you'll probably need a smaller dose of TIZANIDINE HCL.

Alcohol, or any drug that slows the nervous system (including other drugs taken for spasticity), increases the likelihood of drowsiness when taken with TIZANIDINE HCL.
