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.
FAQs
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.
You are not recommended to take Tizanidine with ciprofloxacin as co-administration of these two medicines may cause adverse effects such as slurred speech, dizziness, weakness, confusion, low blood pressure, and drowsiness. However, please consult a doctor before taking Tizanidine with other medicines.
Tizanidine may cause low blood pressure, especially in patients taking antihypertensive drugs (high blood pressure-lowering medicines) or other medicines such as fluvoxamine or ciprofloxacin. However, if you experience signs of low blood pressure, such as dizziness, lightheadedness, blurred vision, or fainting, please consult a physician.
Tizanidine is not recommended for patients suffering from psychotic disorders, as it may cause hallucinations or worsen the condition. Therefore, inform your doctor if you have any psychotic disorders before taking Tizanidine.
You are recommended to avoid taking caffeinated foods with Tizanidine as Tizanidine interacts with caffeine and causes severely low blood pressure and increases the risk of other adverse effects such as dizziness, irregular heartbeat, light-headedness, drowsiness, or fainting. However, please consult a doctor if you experience any of these symptoms while taking Tizanidine.
