This combination medication is used to temporarily treat cough and runny/stuffy nose (nasal congestion) caused by infections (such as the common cold), allergies (such as hay fever), and other breathing illnesses. This product is usually not used for ongoing cough from smoking or long-term breathing problems (such as chronic bronchitis, emphysema) unless directed by your doctor. Guaifenesin is an expectorant. It works by thinning and loosening mucus in the airways, clearing congestion, and making breathing easier. Pseudoephedrine is a decongestant (sympathomimetic). It reduces nasal congestion by narrowing the blood vessels in the nose.
If you are self-treating with this medication, it is important to read the package instructions carefully before you start using this product to be sure it is right for you. (See also Precautions section.)
