Tizanidine (AKA Zanaflex) is a muscle relaxant that is used to treat muscle cramps and tightness as found in certain types of arthritis especially fibromyalgia. Tizanidine is typically used for any disorder that causes your muscle to become stiff. In arthritis, it is commonly prescribed as a temporary relief measure. (Same in fibromyalgia treatment.)
How does Zanaflex work?
Tizanidine is a short acting muscle relaxer that blocks nerve signals from the spinal cord to the brain. When Tizanidine decreases the muscle cramps, the pain being experienced can be improved.
The safeness for use by pregnant ladies or lactating moms
No, it is not safe for pregnant ladies or lactating moms. They should never try it.
Potential Zanaflex side effects
Just when it was starting to sound pretty good…Tizanidine can cause more serious side effects than other drugs in its class. Aside from the usual dizziness, fatigue, dry mouth and confusion, Zanaflex may also cause low blood pressure and heart rate, urinary tract infection, flulike symptoms and speech disturbances! And that’s not all! Serious side effects include severe low blood pressure, high blood pressure and heart rate (upon discontinuance), cornea and retinal damage, kidney toxicity and hallucinations. Yikes!
Dangers of drug interactions
Because of the risk of drug interactions, it cannot be taken with the antidepressant Luvox or the antibiotic Cipro.
Drawbacks & limitations
Watch out if you have low blood pressure, heart disease, kidney disease or liver disease. The elderly should take extra care because they may be more sensitive to the effects.
