Is Flexeril (Cyclobenzaprine) Addictive?

Key Takeaways

Is Flexeril (Cyclobenzaprine) Addictive?

Flexeril depresses the user’s central nervous system, easing discomfort and increasing feelings of relaxation. Although most doctors don’t consider Flexeril addictive, people who find its effects enjoyable might misuse it.

Flexeril is intended for short-term use. Long-term use can lead to physical dependence. Taking the drug in higher-than-recommended doses also increases the risk of addiction.

Signs of a Flexeril addiction include:

  • Using the drug for longer than prescribed
  • Needing to increase dosage amount to achieve the same effects
  • Not being able to stop using the drug
  • Spending a lot of time thinking about the drug, trying to get more of it, and using it
  • Experiencing withdrawal symptoms when not taking the drug
  • Neglecting responsibilities and relationships in favor of taking the drug

What is Flexeril?

Flexeril (cyclobenzaprine) is a prescription muscle relaxer. Doctors prescribe it for the short-term relief of muscle pain and muscle spasms. It’s often prescribed for people who suffer strains or sprains. Sometimes people take it in conjunction with physical therapy.

Used properly, Flexeril is considered safe and effective. Abusing Flexeril puts users at a higher risk of complications and drug addiction. 

Can You Take Flexeril Long Term?

Flexeril is a prescription medication recommended for short-term use. Long-term use of muscle relaxers increases the risk of addiction. 

There is also a risk of physical problems from long-term use, including stomach problems and physical tolerance. Long-term use increases the chances users will experience withdrawal symptoms when they stop using Flexeril.

Risks of Flexeril Abuse

Most people misuse and abuse Flexeril because it produces a feeling of relaxation. Over time, people tend to increase their dosage to increase the same effects.

Abuse increases the risk of overdose. Flexeril overdose symptoms include:

  • Hallucinations
  • Chest pain
  • Rapid heartbeat
  • Vomiting
  • Difficulty breathing
  • Slurred speech
  • Extreme drowsiness

Flexeril overdose puts people at risk of:

  • Cardiac arrest
  • Low blood pressure
  • Seizures
  • Central nervous system depression

Combining Flexeril with alcohol and/or other drugs increases the risk of overdose.

Flexeril Addiction Treatment

Flexeril addiction treatment varies based on the person’s specific situation. Common treatment options include:

Inpatient Treatment

Inpatient treatment allows people to live full-time at the treatment facility. They receive round-the-clock medical supervision. Most inpatient programs last 30 days, but some need a longer stay.

The programs combine a variety of treatment approaches, including:

  • Medically supervised detox
  • Group counseling
  • Individual therapy
  • Support groups and 12-step programs 

Outpatient Treatment

Outpatient treatment allows people to participate in treatment without staying overnight. They live off-site but spend several hours per week in treatment. These programs include:

  • Individual counseling
  • Group therapy
  • Access to medication

The primary benefit of these programs is that participants can still tend to their responsibilities and spend time with loved ones while undergoing treatment.

12-Step Programs

12-step programs, including Narcotics Anonymous, offer access to treatment with great flexibility. These programs use the traditional 12-step approach introduced by Alcoholics Anonymous. These programs are used independently or in conjunction with other treatment approaches.


Dual-diagnosis treatment programs treat a person’s addiction and any co-occurring mental health issues.

When choosing a treatment program, consider the following:

  • Location
  • Cost and health insurance coverage
  • Accreditation
  • Philosophy
