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.

    Macrobid Antibiotic 100 mg Uses & indications:

    Chemical Name: NITROFURANTOIN (nye-troe-fyoor-AN-toyn)

    Macrobid antibiotic is also known as nitrofurantoin. This medication is used to treat bladder infections and urinary tract infections. It works by stopping the growth of bacteria.

    This medication only works for bacterial infections, and it will not work for viral infections such as common cold or flu. Macrobid antibiotic should not be used for infants younger than 1-month-old and should not be used to treat infections apart from those caused by bacteria.

    You can grab Macrobid 100mg from Canada pharmacy.


    Macrobid 100mg is to be taken orally and can be taken with or without food; as advised by your doctor. It can be taken every usually 2 times a day, every 12 hours.

    The dosage of this infection medicine depends on your medical condition and how you respond to treatments. Make sure to take the Macrobid antibiotic at an evenly spaced time.

    Do not use magnesium trisilicate which contains antacids while taking this drug as these antacids can bind with nitrofurantoin and prevent it from being absorbed into the system fully.

    Continue to take this medication even after the full prescribed time is finished and the symptoms disappear as stopping the medication too early will allow the symptoms to return and the bacteria to grow again.


    The ingredients include nitrofurantoin 100mg, talc, corn starch, lactose, carbopol, povidone, sugar, and magnesium stearate.
