What is a common side effect of muscle relaxers?

1. Increased heart rate

2. GI upset

3. Insomnia

4. Dry mouth

The correct answer is: GI upset

A common side effect of muscle relaxers is gastrointestinal (GI) upset, which can manifest as nausea, constipation, or diarrhea. Muscle relaxers work by affecting the central nervous system or directly on muscle tissue, which can disrupt normal digestive processes and cause discomfort. This disruptive effect on the gastrointestinal system is notable because muscle relaxers can influence muscle tone and motility in the gut. While other options like dry mouth or insomnia can also occur with some muscle relaxers, GI upset tends to be more frequently reported. The impact on the digestive system is a critical consideration for those taking these medications, as it can significantly affect a patient's comfort and overall quality of life. Understanding the side effects assists in monitoring and managing any discomfort that may arise during treatment.
