Have you ever wondered why a widely used muscle relaxant like Flexeril was discontinued? Flexeril, also known by its generic name cyclobenzaprine, was a popular medication for treating muscle spasms and associated pain.
Its discontinuation left many patients and healthcare providers searching for answers and alternative treatments. In this article, we’ll explore the reasons behind Flexeril’s discontinuation and its impact on the medical community.

What is Flexeril?
Flexeril was first approved by the FDA in 1977 as a short-term treatment for muscle spasms. It works by blocking nerve impulses sent to the brain, thereby helping to relax muscles. Typically, doctors prescribed it for no more than two to three weeks.
Despite its effectiveness, Flexeril came with several side effects, such as drowsiness, dizziness, and dry mouth. It was also known to interact with other medications, including antidepressants and opioids,
which increased the risk of side effects. Over the years, Flexeril became one of the most prescribed medications in the United States, with millions of prescriptions filled annually.
Why Was Flexeril Discontinued?
Flexeril’s discontinuation was due to a combination of safety concerns, the risk of abuse, and the availability of safer alternatives. One major reason was the side effects. Common side effects included drowsiness, dizziness, and dry mouth. More severe side effects like cardiac issues and serotonin syndrome posed significant risks. These side effects often outweighed the benefits, especially given the availability of newer medications with fewer adverse effects.
Moreover, Flexeril had a potential for misuse and dependency. Although it was classified as a Schedule IV controlled substance, indicating a low potential for abuse, there were increasing reports of misuse. Patients sometimes used it in combination with other substances, leading to dangerous interactions and heightened risk of addiction.
Another critical factor was the introduction of newer, safer muscle relaxants. Medications such as Baclofen, Tizanidine, and Methocarbamol offered similar benefits but with fewer side effects. These alternatives provided effective muscle relaxation without the same level of risk, making them preferable options for many healthcare providers and patients.
Additionally, regulatory changes and market dynamics played a role. Stricter regulations on the use of muscle relaxants led to a re-evaluation of Flexeril’s safety profile. In 2020, Amneal Pharmaceuticals, the manufacturer, decided to discontinue Flexeril, partly due to these evolving standards and the competitive landscape.
Alternatives to Flexeril
With Flexeril no longer available, several alternatives have emerged to fill the gap in muscle relaxant therapy. These alternatives vary in their mechanisms of action and side effect profiles, offering different benefits for patients with muscle spasms and related conditions.
Baclofen
Baclofen is a commonly prescribed muscle relaxant, particularly for conditions like multiple sclerosis and spinal cord injuries. It works by inhibiting nerve transmission in the spinal cord, reducing muscle spasticity.
While effective, Baclofen can cause side effects such as dizziness, fatigue, and weakness. It is available in both oral and injectable forms, providing flexibility in administration.
Tizanidine
Tizanidine is another alternative to Flexeril. It acts on the central nervous system to block nerve impulses that cause muscle spasms. Tizanidine is particularly noted for its lower incidence of drowsiness compared to Flexeril, making it a preferred option for some patients.
However, it can cause side effects like dry mouth, low blood pressure, and sedation, which need to be managed carefully.
Methocarbamol
Methocarbamol is often used to treat muscle spasms associated with acute pain and injuries. It works by depressing the central nervous system, leading to muscle relaxation.
Methocarbamol is available in oral and injectable forms, and its side effects include drowsiness, dizziness, and nausea. Its relatively mild side effect profile makes it a suitable alternative for many patients.
Diazepam
Diazepam, known by its brand name Valium, is a benzodiazepine that also functions as a muscle relaxant. It is effective for short-term relief of muscle spasms but comes with a higher risk of dependency and abuse.
Diazepam can cause sedation, dizziness, and coordination issues, so it is typically used with caution.
Non-Pharmacological Treatments
Beyond medications, non-pharmacological treatments can provide significant relief for muscle spasms. Physical therapy helps improve muscle strength, flexibility, and overall function.
Techniques like stretching, massage, and exercise are often recommended. Additionally, practices such as yoga and meditation can aid in managing muscle tension and pain, promoting overall well-being.
Patients should work closely with their healthcare providers to determine the most appropriate treatment. Each alternative has its own set of benefits and risks, and a personalized approach ensures optimal care and symptom management.

No, Flexeril has been discontinued and should not be used for any condition. Patients previously using Flexeril should consult their healthcare providers to find suitable alternatives.
Are there safer alternatives to Flexeril?
Yes, there are several safer alternatives to Flexeril. Medications like Baclofen, Tizanidine, Methocarbamol, and Diazepam offer similar muscle relaxant benefits with fewer side effects and lower risk of abuse.
What should I do if I have been prescribed Flexeril?
If you have been prescribed Flexeril, it is important to consult your healthcare provider about transitioning to an alternative treatment. Your provider can recommend other muscle relaxants or non-pharmacological therapies that are better suited to your needs.
Can I still use cyclobenzaprine instead of Flexeril?
While Flexeril has been discontinued, the generic version, cyclobenzaprine, is still available. However, it is essential to consult with your healthcare provider before using cyclobenzaprine to ensure it is safe and appropriate for your condition.
Wrapping Up
In summary, the discontinuation of Flexeril (cyclobenzaprine) was driven by multiple factors, including safety concerns, the potential for misuse, and the emergence of safer alternatives. This decision has significantly impacted both patients and healthcare providers, necessitating adjustments in treatment plans and the adoption of new medications or therapies.
