Which is Stronger Tizanidine or Cyclobenzaprine?

Multiple drug ingestion (including alcohol) is common in deliberate cyclobenzaprine overdose. As management of overdose is complex and changing, it is recommended that the physician contact a poison control center for current information on treatment. Signs and symptoms of toxicity may develop rapidly after cyclobenzaprine overdose; therefore, hospital monitoring is required as soon as possible. The acute oral LD50 of FLEXERIL is approximately 338 and 425 mg/kg in mice and rats, respectively. The plasma concentration of cyclobenzaprine is increased in the elderly (see CLINICAL PHARMACOLOGY, Pharmacokinetics, Elderly).

• Muscle spasm, local pain and tenderness, limitation of motion, and restriction in activities of daily living were evaluated.
• The usual dose is 5–10mg three times daily and treatment for more than 2–3 weeks is not recommended.
• Also avoid driving, operating machinery, or other hazardous activities until you know how cyclobenzaprine affects you.
• This can help keep levels of this drug from building up too much in your body.

The incidence of drowsiness, the most frequent adverse reaction, was similar with both drugs. Eight double-blind controlled clinical studies were performed in 642 patients comparing FLEXERIL 10 mg, diazepam, and placebo. Muscle spasm, local pain and tenderness, limitation of motion, and restriction in activities of daily living were evaluated.

Health Concerns

Its side effect profile is generally manageable, involving potential dizziness or lightheadedness; it is also well-tolerated across diverse populations. This study also highlighted that Chlorzoxazone has become a common choice globally for treating musculoskeletal disorders due to its effectiveness. Flexeril, on other hand, is also used as a muscle relaxant but it works differently than Chlorzoxazone.

Cyclobenzaprine is a muscle relaxer used to treat muscle spasms and acute muscle pain. It’s not intended for long-term use or to treat chronic pain. Cyclobenzaprine and muscle relaxers like it are usually prescribed following an injury, car accident, or another minor incident that causes muscle spasms and other temporary muscle conditions. It can also enhance the effects of agents with CNS depressant activity.

Also, cyclobenzaprine can cause dry mouth because it has anticholinergic effects. Cyclobenzaprine belongs to a class of drugs called muscle relaxants. A class of drugs is a group of medications that work in a similar way. The recommended dose of immediate-release cyclobenzaprine is 5 to 10mg, three times a day, while that for extended-release versions is 15 to 30 mg, once a day. Maximum daily dose for either form is 30 mg over the course of 24 hours. Taking more may result in adverse Flexeril side effects or overdose.

CLINICAL PHARMACOLOGY

The efficacy of FLEXERIL 5 mg was demonstrated in two seven-day, double-blind, controlled clinical trials enrolling 1405 patients. One study compared FLEXERIL 5 mg and 10 mg t.i.d. to placebo; and a second study compared FLEXERIL 5 mg and 2.5 mg t.i.d. to placebo. Primary endpoints for both trials were determined by patient-generated data and included global impression of change, medication helpfulness, and relief from starting backache. Each endpoint consisted of a score on a 5-point rating scale (from 0 or worst outcome to 4 or best outcome).

Properly discard this product when it is expired or no longer needed. This medication has been prescribed for your current condition only. Do not use it later for another condition unless your doctor directs you to do so. Alcohol or marijuana (cannabis) can make you more dizzy or drowsy. Do not drive, use machinery, or do anything that needs alertness until you can do it safely.

Less frequent dosing should be considered for hepatically impaired or elderly patients (see PRECAUTIONS, Impaired Hepatic Function, and Use in the Elderly). All patients suspected of an overdose with FLEXERIL should receive gastrointestinal decontamination. This should include large volume gastric lavage followed by activated charcoal. If consciousness is impaired, the airway should be secured prior to lavage and emesis is contraindicated. It is not known whether this drug is excreted in human milk. Because cyclobenzaprine is closely related to the tricyclic antidepressants, some of which are known to be excreted in human milk, caution should be exercised when FLEXERIL is administered to a nursing woman.

Tricyclic antidepressants have been reported to produce arrhythmias, sinus tachycardia, prolongation of the conduction time leading to myocardial infarction and stroke. FLEXERIL may enhance the effects of alcohol, barbiturates, and other CNS depressants. Changes in the electrocardiogram, particularly zanaflex vs flexeril which is stronger in QRS axis or width, are clinically significant indicators of cyclobenzaprine toxicity. Safety and effectiveness of FLEXERIL in pediatric patients below 15 years of age have not been established. FLEXERIL may enhance the effects of alcohol, barbiturates, and other CNS depressants.

How to take cyclobenzaprine

Tricyclic antidepressants have been reported to produce arrhythmias, sinus tachycardia, prolongation of the conduction time leading to myocardial infarction and stroke. Always consult your healthcare provider to ensure the information displayed on this page applies to your personal circumstances. Avoid driving or hazardous activity until you know how cyclobenzaprine will affect you. Call your doctor if your symptoms do not improve after 3 weeks, or if they get worse. Older adults may be more sensitive to the effects of this medicine.
