Flexeril, a muscle relaxant, can cause constipation as a side effect. Other common gastrointestinal side effects include nausea and stomach pain [1].
Why do muscle relaxants like Flexeril cause constipation?
Muscle relaxants, including Flexeril (cyclobenzaprine), can slow down the digestive system. This reduced activity in the intestines can lead to stool moving more slowly, resulting in constipation [2].
What other side effects can Flexeril cause?
Besides constipation, Flexeril can cause drowsiness, dizziness, dry mouth, and fatigue. Less common side effects include blurred vision, headache, and weakness [1].
How should constipation from Flexeril be managed?
If constipation occurs while taking Flexeril, increasing fluid intake and dietary fiber can help. Over-the-counter laxatives may also be used, but it is advisable to consult a healthcare provider for guidance [3].
When does Flexeril's patent expire?
Flexeril, whose active ingredient is cyclobenzaprine, is an older drug and its original patents have long expired. This has allowed for the availability of generic versions of cyclobenzaprine [4]. Information on patent expiry for specific drugs can be found on DrugPatentWatch.com [5].
