Mucinex Fast-Max

Description

Mucinex® FAST-MAX® COLD, FLU & SORE THROAT is a combination medication formulated to address multiple symptoms associated with colds and flu. The active ingredients include acetaminophen, which serves as a pain reliever and fever reducer; dextromethorphan HBr, a cough suppressant; guaifenesin, an expectorant that thins and loosens mucus; and phenylephrine HCl, a nasal decongestant. This formulation is indicated for the control of cough, alleviation of nasal and chest congestion, relief of sinus pressure and congestion, and management of body pain, headache, fever, and sore throat. The product is packaged in a 6 FL OZ (180 mL) bottle and is intended for use by individuals aged 12 years and older.

Uses and Indications

This drug is indicated for the temporary relief of common cold and flu symptoms, including cough, nasal congestion, minor aches and pains, sore throat, headache, stuffy nose, and sinus congestion and pressure. Additionally, it temporarily reduces fever and promotes nasal and/or sinus drainage. The formulation aids in loosening phlegm (mucus) and thinning bronchial secretions, facilitating the clearance of mucus from the bronchial passageways and making coughs more productive.

There are no teratogenic or nonteratogenic effects associated with this drug.

Dosage and Administration

Patients should adhere strictly to the recommended dosage and administration guidelines. The maximum dosage should not exceed 6 doses within a 24-hour period. It is imperative to measure the dose using only the dosing cup provided with the product; the dosing cup should not be used with any other products to ensure accurate measurement.

For adults and children aged 12 years and older, the recommended dose is 20 mL, administered every 4 hours as needed. For children under 12 years of age, the use of this product is not recommended.
