What gastrointestinal side effect is commonly associated with Baclofen?

Baclofen is a muscle relaxant primarily used to treat spasticity. One of the gastrointestinal side effects commonly associated with Baclofen is constipation. This occurs because Baclofen can reduce gastrointestinal motility, which leads to slower movement of stool through the intestines. As the stool remains in the intestines longer, water is reabsorbed, making the stool harder and more difficult to pass, resulting in constipation.

While other gastrointestinal issues such as nausea, diarrhea, and abdominal cramps can occur with various medications, they are not as specifically noted as side effects of Baclofen. It is essential for patients taking Baclofen to be aware of this potential side effect and manage it proactively, such as by drinking plenty of fluids and incorporating fiber into their diet.
