Tizanidine
About Tizanidine
Tizanidine is used to treat muscle spasticity (muscles become heavy, stiff, and difficult to move) caused by spinal cord injuries or multiple sclerosis (the immune system attacks the protective covering of nerves). It is also used to relieve pain, stiffness, and discomfort associated with acute musculoskeletal conditions.
Tizanidine contains Tizanidine (a skeletal muscle relaxant), which works in the spinal cord and brain by calming overactive nerves and blocking the release of chemicals that trigger muscle tightening. Thereby, it allows the muscles to relax and relieves pain, spasms, and stiffness.
Take Tizanidine exactly as advised by your doctor. Swallow it whole with a glass of water; do not crush, chew, or break it. Tizanidine may cause common side effects, including drowsiness, dizziness, dry mouth, flu-like symptoms, vomiting, constipation, nervousness, sore throat, runny nose, blurred vision, or weakness. Please consult your doctor if these side effects persist or worsen.
Inform your doctor if you are allergic to Tizanidine or any other medicines. Let your doctor know before taking Tizanidine if you have low blood pressure or liver/kidney diseases. Tizanidine is not recommended for children, as its safety and effectiveness have not been established. Consult your doctor if you are pregnant or breastfeeding before taking Tizanidine.

Things to avoid:
- Avoid exposure to extreme cold and heat.
- Avoid wearing tight-fitting clothing; instead, choose loose, comfortable garments.
Rest and recovery:
- Rest well and obtain sufficient sleep to support muscle recovery.
- To prevent pressure ulcers, change your position at least every two hours.

Patients Concern
Disease/Condition Glossary
Muscle spasticity: It is a condition in which muscles become stiff, contract, or cause involuntary spasms, making it difficult to move, walk, or talk, and can be painful and uncomfortable. It occurs when the nerve impulses that control muscle movements are damaged or interrupted. Symptoms include muscle tightness, joint stiffness, unusual posture, difficulty in moving, and pain in affected muscles and joints.
