Mucinex, a popular over-the-counter medication, is widely used to relieve chest congestion and cough caused by various respiratory conditions, including the common cold, bronchitis, and sinus infections.

This mechanism of action helps to relieve chest congestion and cough, providing quick relief from respiratory symptoms. However, like all medications, guaifenesin can cause side effects, ranging from mild to severe.
