Mucinex, in its standard form, is designed to relieve congestion without causing drowsiness. Its active ingredient, Guaifenesin, works to thin mucus but does not have sedative properties. However, it's important to check the specific product variant as Mucinex D contains pseudoephedrine, which could contribute to restlessness or difficulty sleeping for some individuals. Always read labels carefully and consult with a healthcare provider for personalized advice.
