Faq for TIZANIDINE - ORAL

Tizanidine is used to treat muscle spasms caused by conditions such as multiple sclerosis or spinal cord injury.

Tizanidine works by blocking nerve impulses that are sent to the brain, which helps to reduce muscle spasms and improve muscle control.

Common side effects of tizanidine may include drowsiness, dizziness, dry mouth, weakness, and fatigue. It may also cause low blood pressure, so it is important to stand up slowly from a sitting or lying position.

Tizanidine should be taken exactly as prescribed by your doctor. It is usually taken every 6 to 8 hours, with or without food. It is important not to suddenly stop taking tizanidine without consulting your doctor, as it may cause withdrawal symptoms.

Tizanidine may harm an unborn baby, so it is important to inform your doctor if you are pregnant or planning to become pregnant. It is generally not recommended to use tizanidine during pregnancy unless the potential benefits outweigh the risks.

Tizanidine may interact with other medications, including blood pressure medications, antidepressants, and certain antibiotics. It is important to inform your doctor about all the medications you are taking to prevent any potential interactions.

If you miss a dose of tizanidine, take it as soon as you remember. However, if it is almost time for your next dose, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for a missed one.

Drinking alcohol while taking tizanidine may increase the side effects of drowsiness and dizziness. It is generally recommended to avoid or limit alcohol consumption while on tizanidine.

Tizanidine may start working within 1 to 2 hours after taking it. The full effects may take several days or weeks to become noticeable, so it is important to be patient and follow your doctor's instructions.
