Expectorants are a type of over-the-counter drug that is used to loosen and thin mucus, making it easier to cough up. They can also help clear the sinuses by loosening any congestion or pressure in the nasal passages. In this blog post, we will discuss how expectorants work, what they’re typically used for, and which brands are best! The key ingredient in most expectorants is guaifenesin, which helps loosen the mucus and thin it to make it easier to cough up. Guaifenesin also functions as a drying agent, so when taken along with other over-the-counter medications that are used for colds or congestion like decongestant nasal sprays (e.g., phenylephrine), they can help dry out your nose and sinuses too! Some people may not experience much of an effect from taking guaifenesin alone, but if you’re having difficulty coughing up phlegm or mucus due to congestion caused by allergies or asthma medication use then this drug might be helpful. It’s always best
