What is a Generic Drug?

A generic drug is a copy of the brand-name drug with the same dosage, safety, strength, quality, consumption method, performance, and intended use. Before generics become available on the market, the generic company must prove it has the same active ingredients as the brand-name drug and works in the same way and in the same amount of time in the body.

The only differences between generics and their brand-name counterparts is that generics are less expensive and may look slightly different (eg. different shape or color), as trademarks laws prevent a generic from looking exactly like the brand-name drug.

Generics are less expensive because generic manufacturers don't have to invest large sums of money to develop a drug. When the brand-name patent expires, generic companies can manufacture a copy of the brand-name and sell it at a substantial discount.

  • Product Details

    Description

    Buckley's Mucus and Phlegm Relief is an over-the-counter (OTC) medication designed to alleviate the discomfort associated with excessive mucus and phlegm. This medication combines guaifenesin and menthol to provide effective relief from respiratory congestion.

    Buckley's Mucus and Phlegm Relief treats conditions with the symptoms of overproduction of mucus and phlegm, such as the common cold, bronchitis, and respiratory infections. Guaifenesin, the active ingredient, is an expectorant. It thins and loosens mucus in the airways, making it easier to clear by coughing. Menthol provides a soothing effect, alleviating throat irritation and enhancing overall comfort.

    Directions

    For adults and children over 12, the usual dosage is 2-3 tsp (10-15 mL) every 6 hours as needed. 

    Follow the dosing instructions provided on the packaging, and only take as directed by your doctor.
