How does Zanaflex work?Tizanidine belongs to a group of medicines called muscle relaxants. When muscles in your body spasm, cramp, or become tight due to medical problems such as multiple sclerosis or spine injury, the condition is known as spasticity. Muscle relaxants like tizanidine and baclofen are used to treat this condition. They work by blocking excess firing of the nerve cells that control muscle movement. Your doctor may choose to use this medication for other conditions not listed here. If you're unsure why you are taking this medication, please ask your doctor. The benefits of tizanidine are related to its effects on the nervous system. The beneficial effects of tizanidine are noticeable within about one hour of taking the first dose.
How should I use Zanaflex?The recommended initial adult dose of tizanidine is 4 mg up to three times daily. The dose is then increased gradually in 2 mg to 4 mg steps until a dose of 8 mg up to three times a day (every 6 to 8 hours) is reached. No more than 36 mg of tizanidine should be taken within a 24-hour period. The use and dose of tizanidine for children must be determined by the doctor.
