Inistón Mucosidad Sabor Menta (Guaifenesin)

Guaifenesin is an expectorant that acts on the respiratory tract to thin and loosen mucus, aiding its clearance in several conditions.

• Chest congestion: loosens thick mucus to improve airway clearance.
• Acute bronchitis: reduces cough severity by facilitating mucus expectoration.
• Upper respiratory tract infection: helps clear nasal and throat secretions.
• Cough associated with the common cold: eases productive cough by thinning secretions.

• Guaifenesin increases the volume of airway secretions while decreasing their viscosity. By stimulating the serous cells of the respiratory epithelium, it promotes the production of a more watery mucus, which can be more readily moved by ciliary action and cough, thereby enhancing mucociliary clearance and reducing airway obstruction.

Guaifenesin is generally well tolerated, but some users may experience adverse reactions.

Guaifenesin may interact with certain medications; awareness helps prevent reduced efficacy or increased risk.

Major Interactions (Avoid)

• Monoamine oxidase inhibitors (MAOIs): concurrent use may increase the risk of hypertensive episodes.
• Phenylpropanolamine-containing products: combined use can elevate blood pressure.

Moderate Interactions (Monitor Closely)

• Codeine or other opioid antitussives: may diminish the expectorant effect of guaifenesin.
• Antihypertensive agents: guaifenesin may modestly affect blood pressure control.
• Diuretics: increased fluid loss could alter mucus hydration; monitor hydration status.
