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


    Your healthcare provider may have prescribed Foradil to treat a chronic lung condition. This medication is indicated for:

    • Treatment of asthma in patients five years or older when combined with other long-term inhalers
    • Prevention of exercise-induced bronchospasm in patients five years or older
    • Treatment of bronchoconstriction in COPD

    Foradil is a long-acting beta-agonist (LABA). These medications work by relaxing the smooth muscles of the bronchioles in the lungs. By doing so, Foradil helps to reduce the daily symptoms of lung disease.


    The usual dosage for asthma or COPD is inhaling one capsule by mouth twice daily.

    For exercise-induced bronchospasm, inhale one capsule 15 minutes before physical activity.

    Do not swallow the capsule. Use the included inhaler device.


    The active ingredient in Foradil is formoterol fumarate.
