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.

    Description

    Mucinex (guaifenesin) is a drug used to help with chest congestion and cough. It works by breaking up mucus in your airways and allowing it to be coughed up more easily. You can buy Mucinex as 600mg or 1200mg tablets. The tablets have an extended-releasing coating on them to allow the drug to be taken less frequently. You should store your Mucinex tablets at room temperature and keep them out of reach of children.

    Directions

    • Swallow the tablets whole. Do not crush or chew them.
    • Take Mucinex with plenty of water.
    • Mucinex can be taken on an empty stomach or with a meal.
    • Mucinex Dosage:
      • Take 600mg - 1200mg every 12 hours. Do not exceed 2400mg per day.
