Is Flexeril Addictive ?
Flexeril (generic name: cyclobenzaprine) is a muscle relaxant commonly prescribed for short-term use to treat muscle spasms. While Flexeril is not classified as a controlled substance and has a low potential for abuse compared to opioids or benzodiazepines, it can still be habit-forming in certain individuals, especially if misused or taken in higher doses than prescribed.
Cyclobenzaprine, sold under several brand names including, historically, Flexeril, is a muscle relaxer used for muscle spasms from musculoskeletal conditions of sudden onset. It is not useful in cerebral palsy. It is taken by mouth.
Common side effects include headache, feeling tired, dizziness, and dry mouth. Serious side effects may include an irregular heartbeat. There is no evidence of harm in pregnancy, but it has not been well studied in this population. It should not be used together with MAOIs. How it works is unclear. In any case, it is known to inhibit serotonin and norepinephrine reuptake and to block serotonin, adrenergic, histamine, and muscarinic acetylcholine receptors. Chemically, it is very similar to tricyclic antidepressants like amitriptyline.
Cyclobenzaprine was approved for medical use in the United States in 1977. It is available by prescription as a generic medication. In 2022, it was the 45th most commonly prescribed medication in the United States, with more than 13 million prescriptions. It was not available in the United Kingdom as of 2012.
Potential for Addiction
- Low Addiction Potential:
- Flexeril is not chemically similar to substances known for high addiction risk, like opioids or stimulants.
- However, misuse or long-term use can lead to psychological dependence in rare cases.
- Physical Dependence:
- Although rare, prolonged use of Flexeril may cause some users to develop tolerance, requiring higher doses to achieve the same effect.
- Abrupt discontinuation after long-term use might cause mild withdrawal symptoms, such as nausea, headache, or fatigue.
- Misuse:
- Some individuals may misuse Flexeril for its sedative effects, leading to off-label or recreational use.
- Misuse increases the risk of dependency, side effects, and other health complications.
Signs of Misuse or Dependence
- Taking Flexeril in higher doses or for longer periods than prescribed.
- Using it without a prescription or for recreational purposes.
- Difficulty stopping the medication despite no longer needing it for medical reasons.
Risks Associated with Misuse
- Sedation and Drowsiness: May impair daily functioning or increase the risk of accidents.
- Cardiovascular Effects: In high doses, Flexeril can cause irregular heartbeat or serious heart-related issues.
- Overdose Risk: Combining Flexeril with alcohol, opioids, or other sedatives can lead to dangerous respiratory depression or even fatal overdose.
Recommendations
- Use as Prescribed:
- Take Flexeril exactly as directed by your healthcare provider, typically for no more than 2-3 weeks.
- Monitor Side Effects:
- Report any unusual symptoms, such as cravings or withdrawal-like feelings, to your doctor.
- Avoid Combining with Alcohol or Sedatives:
- This can amplify the sedative effects and increase risks.
If you have concerns about addiction or dependency on Flexeril, consult a healthcare professional for guidance on tapering or alternative treatments.
