Zanaflex (active ingredient: tizanidine) is a prescription muscle relaxant used to manage muscle spasticity. Muscle spasticity causes certain muscles to remain unusually tight, stiff, or difficult to control.
This condition may occur when the brain, spinal cord, or nerves are damaged or affected by disease. Common causes include multiple sclerosis, spinal cord injury, stroke, and other neurological conditions.
Zanaflex can help reduce muscle tightness and spasms, making movement easier and more comfortable. It may also help improve flexibility, positioning, walking, and the ability to perform daily activities.
Muscle spasticity develops when the nerves that control muscle movement send too many signals to the muscles. These abnormal nerve signals cause the muscles to contract more strongly or more often than they should.
Symptoms may include:
The severity of spasticity can vary throughout the day. Symptoms may become worse with stress, fatigue, sudden movement, infection, or changes in body position.
Zanaflex belongs to a class of medications called alpha-2 adrenergic agonists. It works mainly in the brain and spinal cord, where it reduces the release of nerve signals that cause muscles to tighten.
By decreasing these overactive nerve signals, Zanaflex helps the affected muscles relax. This can reduce muscle tone, stiffness, and spasms without directly acting on the muscle fibres themselves.
Zanaflex does not completely block normal muscle movement. Instead, it helps reduce excessive muscle activity so that movement may become more controlled.
Zanaflex may help improve comfort and physical function by reducing the severity and frequency of muscle spasms. It may also make stretching, physiotherapy, personal care, and daily movement easier.
Some people may use Zanaflex before certain activities, such as physiotherapy, bathing, dressing, or sleeping, when muscle relaxation is especially helpful.
The medication has a relatively short duration of action. For this reason, a healthcare provider may schedule each dose around the times when symptom relief is most needed.
The dose of Zanaflex is usually adjusted for each person. A healthcare provider may begin with a low dose and increase it gradually based on symptom control, treatment goals, and side effects.
The correct dose depends on several factors, including the severity of spasticity, other medical conditions, current medications, and how the body responds to treatment.
Taking too much Zanaflex can cause excessive drowsiness, dizziness, weakness, slow heart rate, or low blood pressure. The medication should only be taken as prescribed.
Zanaflex helps control the symptoms of muscle spasticity, but it does not cure the condition causing it. It may be used together with physiotherapy, stretching, mobility exercises, braces, or other treatments.
A complete treatment plan may focus on reducing pain, improving movement, preventing muscle shortening, and supporting greater independence with daily activities.
Zanaflex may cause drowsiness, dizziness, weakness, or low blood pressure. These effects may be more noticeable when treatment begins or after the dose is increased.
Avoid driving, operating machinery, or performing activities that require alertness until you know how the medication affects you.
Do not stop taking Zanaflex suddenly after regular or high-dose use. Sudden discontinuation may cause increased blood pressure, a rapid heartbeat, or worsening muscle tightness. A healthcare provider may need to reduce the dose gradually.
Contact a healthcare provider if your muscle spasms become worse, the medication causes severe side effects, or the treatment is not providing enough relief.
Take Zanaflex exactly as prescribed by your healthcare provider. The medication is taken by mouth as a tablet and is usually used two or three times a day, depending on the severity and timing of your muscle spasticity.
Read the prescription label carefully and follow all dosing instructions. Do not take a larger dose, take it more often, or continue treatment longer than directed.
Because Zanaflex has a relatively short duration of action, a healthcare provider may schedule each dose around times when muscle relaxation is most needed, such as before physiotherapy, daily activities, or bedtime.
Zanaflex should be taken consistently in relation to meals. Take every dose either with food or without food.
Food can change the way the body absorbs Zanaflex. Frequently switching between taking it with food and taking it on an empty stomach may change the amount of medication in your bloodstream. This can affect how well the medication works and may increase the risk of side effects.
Speak with a healthcare provider before changing how you take Zanaflex in relation to meals.
The usual starting dose for adults aged 18 years and older is 2 mg by mouth. This dose may be taken up to three times daily, as directed by a healthcare provider.
Treatment usually begins with a low dose because Zanaflex can cause drowsiness, dizziness, weakness, low blood pressure, or a slow heart rate. Starting with a small dose allows the body time to adjust to the medication.
A healthcare provider may gradually increase the dose if the starting dose does not provide enough relief. Dose adjustments are based on several factors, including:
Do not increase the dose on your own. Taking more medication than prescribed can increase the risk of severe drowsiness, fainting, breathing problems, or dangerously low blood pressure.
The total amount of Zanaflex should not exceed 36 mg within 24 hours. The medication is usually divided into several smaller doses rather than taken all at once.
Do not take more than the prescribed number of doses per day. Leave the recommended amount of time between doses.
Take a missed dose when you remember, unless it is almost time for your next scheduled dose. If your next dose is due soon, skip the missed dose and continue with your regular schedule.
Do not take two doses at the same time or take extra medication to make up for a missed dose.
Do not suddenly stop taking Zanaflex without speaking with a healthcare provider. Abruptly stopping treatment can cause withdrawal symptoms, particularly after using high doses or taking the medication regularly for a long period.
Possible withdrawal symptoms include:
A healthcare provider will usually reduce the dose gradually. This process allows the body to adjust and lowers the risk of withdrawal symptoms.
Zanaflex is not approved for use in children younger than 18 years. Its safety and effectiveness have not been established in this age group.
A healthcare provider should carefully evaluate other treatment options for children with muscle spasticity.
Zanaflex may cause drowsiness, dizziness, weakness, or reduced alertness. Avoid driving, operating machinery, or performing activities that require balance or concentration until you understand how the medication affects you.
Stand up slowly after sitting or lying down because Zanaflex may lower blood pressure and cause dizziness or fainting.
Avoid drinking alcohol unless a healthcare provider says it is safe. Alcohol can increase drowsiness, dizziness, and other nervous system effects.
A healthcare provider may monitor your response to Zanaflex and adjust the dose when necessary. Blood pressure, heart rate, liver function, and muscle symptoms may be checked during treatment.
Contact a healthcare provider if Zanaflex does not adequately control your muscle spasms or causes severe drowsiness, fainting, yellowing of the skin or eyes, unusual weakness, hallucinations, or difficulty breathing.
Zanaflex (Tizanidine) is available in the following forms and strength:
Zanaflex may cause drowsiness, dizziness, weakness, or reduced alertness. These effects can impair your ability to drive, operate machinery, or perform tasks that require concentration and coordination.
Avoid these activities until you know how the medication affects you.
Zanaflex may lower blood pressure, especially when treatment begins or after the dose is increased. This can cause dizziness, light-headedness, or fainting.
Stand up slowly after sitting or lying down. Contact a healthcare provider if you experience severe dizziness, fainting, or unusual weakness.
Zanaflex can interact with certain medications, including some antibiotics, antifungal medicines, blood pressure medications, sedatives, and other drugs that cause drowsiness.
Tell your healthcare provider about all prescription medications, nonprescription products, vitamins, and supplements you use. Some combinations may increase the risk of severe drowsiness, low blood pressure, or other serious side effects.
Zanaflex should be used carefully in people with liver disease because it may cause or worsen liver damage. A healthcare provider may order blood tests to monitor liver function during treatment.
Seek medical attention if you develop yellowing of the skin or eyes, dark urine, unusual tiredness, loss of appetite, nausea, or pain in the upper-right side of the abdomen.
Zanaflex should only be used during pregnancy when a healthcare provider determines that the potential benefits outweigh the possible risks.
Tell your healthcare provider if you are pregnant, planning to become pregnant, or think you may be pregnant.
Do not use Zanaflex if you are allergic to tizanidine or any other ingredient in the medication.
Seek immediate medical care if you develop swelling of the face, lips, tongue, or throat, difficulty breathing, hives, or a severe skin reaction.
Zanaflex may cause dry mouth. Reduced saliva can increase the risk of tooth decay, gum disease, mouth sores, and discomfort.
Drink water regularly, maintain good oral hygiene, and speak with a dentist or healthcare provider if dry mouth continues or becomes severe.
Zanaflex may cause nausea, vomiting, stomach discomfort, constipation, or other digestive symptoms.
Contact a healthcare provider if these effects are severe, persistent, or prevent you from eating or drinking normally.
Zanaflex may slow thinking, reaction time, and physical coordination. Use extra caution if your work or daily activities require a high level of alertness, balance, or precision.
This is especially important for people who drive professionally, operate heavy machinery, work at heights, or perform safety-sensitive tasks.
Do not stop taking Zanaflex suddenly after regular or long-term use. Abrupt discontinuation may cause withdrawal symptoms, including increased blood pressure, rapid heart rate, worsening muscle tightness, or increased spasms.
A healthcare provider will usually reduce the dose gradually to help prevent withdrawal symptoms.
Zanaflex is not usually considered addictive in the same way as opioids or certain sedatives. However, the body can become physically dependent on it, especially when it is taken regularly, in high doses, or for a long time. Do not take more than prescribed or stop the medication suddenly. A healthcare provider may need to reduce the dose gradually to prevent withdrawal symptoms such as increased blood pressure, a rapid heart rate, or worsening muscle tightness.
Yes. Zanaflex can interact with other medications and may increase the risk of severe drowsiness, dizziness, low blood pressure, or other side effects.
