Flexeril (cyclobenzaprine) is known to cause drowsiness [1]. This side effect is common and can impair a person's ability to drive or operate machinery [2].
Why is drowsiness a common side effect of Flexeril?
Drowsiness occurs because cyclobenzaprine, the active ingredient in Flexeril, affects the central nervous system [1]. It works by acting on the brain and spinal cord to relax muscles [3]. This mechanism of action can lead to sedative effects [1].
How long does the drowsiness from Flexeril typically last?
The duration of drowsiness can vary among individuals. It is generally most pronounced when starting the medication or increasing the dose [2]. Some people may experience it throughout the day, while for others, it subsides as their body adjusts to the drug [1].
What should I do if I feel too sleepy from Flexeril?
If you experience significant drowsiness, it is recommended to avoid activities that require alertness, such as driving or operating heavy machinery [2]. Discussing this side effect with your doctor is advisable, as they may adjust your dosage or suggest an alternative medication [1].
Are there alternatives to Flexeril that cause less drowsiness?
Other muscle relaxants are available, and some may have different side effect profiles. For example, medications like baclofen or tizanidine are sometimes used, though they can also cause drowsiness [4]. Metaxalone is an alternative that is generally considered less sedating than cyclobenzaprine [5]. It is important to consult a healthcare professional to determine the most suitable option based on individual needs and medical history [1, 4, 5].
