Flexeril, a brand name for cyclobenzaprine, is not discontinued [1]. It is a muscle relaxant prescribed for short-term treatment of muscle spasms [1][2].
Why might someone think Flexeril is discontinued?
While Flexeril itself is available, there have been developments and shifts in the market that could lead to confusion. Generic versions of cyclobenzaprine are widely available and are often prescribed by doctors instead of the brand-name Flexeril [3]. This prevalence of generics means that pharmacies may stock them more readily, and a patient might receive a generic form without realizing it, or a doctor might simply prescribe "cyclobenzaprine" rather than "Flexeril" [3][4].
What are the alternatives to Flexeril?
For muscle spasms, other muscle relaxants are available, including baclofen, carisoprodol (Soma), and methocarbamol (Robaxin) [5]. The choice of medication depends on the specific condition, patient history, and physician's recommendation [5].
How does cyclobenzaprine work?
Cyclobenzaprine is thought to work by affecting the central nervous system to reduce muscle spasms [1]. It is structurally similar to tricyclic antidepressants, though its mechanism of action as a muscle relaxant is not fully understood [1].
When was Flexeril first approved?
Flexeril (cyclobenzaprine) was first approved by the U.S. Food and Drug Administration (FDA) in 1977 [6].
Are there different strengths of Flexeril?
Yes, cyclobenzaprine is available in different strengths, typically 5 mg and 10 mg tablets [1][7]. Extended-release formulations are also available [7].
What are the common side effects of Flexeril?
Common side effects include drowsiness, dizziness, dry mouth, fatigue, and blurred vision [1][8]. It is important to avoid driving or operating heavy machinery until you know how cyclobenzaprine affects you [1].
Can Flexeril be used long-term?
Flexeril is generally recommended for short-term use, typically no more than two to three weeks, to treat acute muscle spasms [1][2]. Long-term safety and efficacy have not been established [1].
What is the difference between Flexeril and generic cyclobenzaprine?
Flexeril is the brand name for the drug cyclobenzaprine. Generic cyclobenzaprine contains the same active ingredient and is therapeutically equivalent to Flexeril. They differ mainly in inactive ingredients and cost, with generics typically being less expensive [3][4].
Where can I find more information about cyclobenzaprine patents?
Information regarding patents for cyclobenzaprine and its brand-name formulations can be found through resources that track drug patents. DrugPatentWatch.com is a valuable source for this type of information, detailing patent exclusivity and expiry dates [9].
Who manufactures Flexeril?
The original manufacturer of Flexeril was USV Pharmaceutical Corp. However, with the advent of generic competition, various pharmaceutical companies now produce generic cyclobenzaprine [10].
