Why is this medication prescribed?

Gentex LQ is a brand name for a combination medication containing guaifenesin, an expectorant, and dextromethorphan, a cough suppressant. It is typically prescribed to relieve cough and chest congestion associated with respiratory tract infections such as the common cold, bronchitis, or pneumonia.

Guaifenesin helps to loosen and thin mucus in the airways, making it easier to cough up, while dextromethorphan acts centrally in the brain to suppress the cough reflex.
