Summary
Tizanidine is used to treat muscle spasms, which are sudden, involuntary muscle contractions. It is effective for conditions like multiple sclerosis, which is a disease affecting the brain and spinal cord, and spinal cord injury, which refers to damage to the spinal cord that can cause loss of function.
Tizanidine works by blocking nerve signals that cause muscles to tighten. It acts on the central nervous system, which includes the brain and spinal cord, to relax muscles and reduce spasms, improving muscle tone and comfort.
Tizanidine is usually taken orally, which means by mouth, with a starting dose of 2 mg up to three times a day. The maximum recommended dose is 36 mg per day. Dosage may be adjusted by a doctor based on individual needs.
Common side effects of Tizanidine include drowsiness, which means feeling sleepy, dry mouth, which is a lack of saliva, and dizziness, which is a sensation of spinning or losing balance. These effects are usually mild and temporary.
Tizanidine can cause low blood pressure, which may lead to dizziness or fainting. It should not be taken with certain medications like ciprofloxacin, which is an antibiotic. People with liver disease should use caution, as Tizanidine can affect liver function.
