Zanaflex is a fastacting drug, meaning that it remains in the body for only a few hours. Zanaflex should therefore only be taken when necessary during the day.
Zanaflex is mostly used as a treatment to ease the pain that is associated with certain conditions. These conditions include multiple sclerosis, back pain, injuries to the spine, and a form of cerebral palsy known as spastic diplegia.
Zanaflex may also be used in the treatment of headaches and insomnia.
How Zanaflex Works
Zanaflex belongs to a group of drugs called alpha-2 adrenergic agonists. These block the action of the alpha-2 receptors in the central nervous system, leading to a reduction in the strength of the signals that are sent to the spinal cord and therefore to the brain.
This will relieve the muscle of some of the tension as well as reduce muscular contraction.
Zanaflex also allows for increased mobility for those who are undergoing rehabilitation by reducing the stiffness of the muscles. It acts on the spine and not directly on the muscles.
Zanaflex Dosage: You should use Zanaflex as prescribed by the doctor. You should also not exceed thirtysix milligrams of Zanaflex in any twenty four hour period.
You should speak to your doctor before he prescribes Zanaflex for you if you suffer from any liver condition such as liver cirrhosis, hepatitis or liver failure. You should also inform your doctor if you suffer from a condition known as QT syndrome, if you are allergic to any ingredient in the medication, if you have any kidney problems, if you have a condition known as hypotension (low blood pressure) or if you suffer from a slow heart rate, a condition known as bradycardia.
Before you start to use Zanaflex inform your healthcare professional of any drugs that you may be taking, because they may interact with Zanaflex.
You should also not take Zanaflex if you partake in any activity that will require muscle tone. Zanaflex comes in capsule and tablet forms.
You should not change the kind of Zanaflex that you are using unless it is following your doctor’s advice. Each of these have different therapeutic effects.
