Quick Facts Scannable
- Flexeril: Primarily used as a muscle relaxant for skeletal muscle spasms.
- Xanax: Used mainly to treat anxiety and panic disorders.
- Mechanism: Flexeril works by blocking nerve impulses. Xanax enhances the effect of a neurotransmitter called GABA.
- Common Forms: Flexeril is usually available in tablet form. Xanax can be found as tablets or an oral solution.
- Key Caution: Both are not advisable for long-term use without medical supervision.
- Common Side Effects: Flexeril may cause drowsiness and dry mouth; Xanax often leads to sedation and dizziness.
- Interactions: Caution is advised when taking with other CNS depressants, such as alcohol.
- Special Populations: Use cautiously in pregnant women, elderly, and individuals with liver or kidney disease.
- Seek Urgent Help: If experiencing severe side effects like difficulty breathing or swelling in the face.
What It Is and How It Works
Flexeril
Flexeril (cyclobenzaprine) is a muscle relaxant that works by blocking nerve impulses (or pain sensations) sent to your brain. It is typically used in conjunction with rest and physical therapy for short-term relief of muscle spasms associated with acute musculoskeletal conditions.
Xanax
Xanax (alprazolam) is a benzodiazepine that affects the brain and nerves (central nervous system) to produce a calming effect. It works by enhancing the effects of gamma-aminobutyric acid (GABA), a natural chemical in the body that has calming effects.
Indications / Uses
Flexeril
Approved primarily for the relief of muscle spasms associated with acute, painful musculoskeletal conditions. It is not intended for long-term use and is typically prescribed for a few weeks.
Xanax
Primarily indicated for the management of anxiety disorders or for the short-term relief of symptoms of anxiety. It is also used in the treatment of panic disorders, with or without agoraphobia. Off-label uses might include treatment for sleep disorders, but such use should be guided by a clinician.
Dosage Forms and Typical Dosing Considerations
Flexeril: Commonly found in tablet form, with typical dosing ranging from 5 mg to 10 mg, taken three times a day. Its use should be carefully monitored especially in older adults or those with hepatic impairment.
Xanax: Available as tablets and extended-release tablets, starting typically at doses of 0.25 mg to 0.5 mg for anxiety, taken 2 to 4 times daily. As with Flexeril, dosage must be individualized with careful monitoring, particularly in the elderly and those with hepatic conditions.
How to Take It Correctly Step-by-Step
- Always follow the prescription label and your doctor\’s instructions.
- Take Flexeril and Xanax exactly as prescribed by your healthcare provider.
- Flexeril can be taken with or without food, typically 3 times a day.
- Xanax should generally be taken as needed for anxiety but prescribed for regular use based on condition and response.
- Store both medications at room temperature, away from excessive heat and moisture.
- If you miss a dose of Flexeril, take it as soon as you remember unless it\’s almost time for your next dose. With Xanax, maintain the prescribed schedule.
- Avoid alcohol and other CNS depressants while taking either medication.
- Do not double doses to make up for a missed one.
Side Effects Common to Serious
Common Side Effects
Flexeril: Drowsiness, dry mouth, and dizziness.
Xanax: Drowsiness, sedation, and fatigue.
Less Common Side Effects
Flexeril: Confusion, nervousness.
Xanax: Headache, difficulty concentrating.
Serious Side Effects
Seek immediate medical help if experiencing:
- Shortness of breath

Contraindications & Precautions
Flexeril: Contraindicated in individuals taking MAO inhibitors or with thyroid troubles, heart block, or cardiac arrhythmias. Exercise caution in the elderly and patients with hepatic impairment.
Xanax: Contraindicated in those with acute narrow-angle glaucoma and individuals on ketoconazole or itraconazole. Careful use is advised in elderly patients and those with a history of substance abuse.
Drug, Food, and Supplement Interactions
Flexeril and Xanax both have potential interactions with other CNS depressants. Mixing these with alcohol can increase sedative effects, potentially leading to dangerous levels of respiratory depression.
Patients should always inform their healthcare provider about all medications, including OTC drugs and supplements, to avoid adverse interactions.
