Mucinex, the brand name for guaifenesin, is a commonly used expectorant for relieving chest congestion and other symptoms associated with respiratory conditions. Guaifenesin works by increasing the water content in the mucus. This drug is often combined with other medications to address multiple symptoms. Mucinex is commonly found in both single-ingredient and combination products, making it a versatile option for managing cough and congestion. Although generally well-tolerated, Mucinex can cause certain side effects in some individuals who use it.

Mucinex is an expectorant that contains guaifenesin as its active ingredient, which functions by increasing the water content of mucus, reducing its viscosity, and helping clear congestion. It stimulates the gastric mucosa, which further helps loosen the mucus in the airways, making it easier to cough out through the mouth. This mechanism of action makes it effective in relieving respiratory conditions such as colds and bronchitis.
Common Mucinex side effects may include:
Serious side effects (rare):
Note: Call your healthcare provider if you experience any severe symptoms or unusual changes.

Certain medications may interact with Mucinex, including prescription and over-the-counter drugs, as well as herbs, and affect how it works. Inform your doctor beforehand to prevent and manage potential interactions with Mucinex.
