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


    Valtrex is a prescription antiviral that can be used to treat the following conditions:

    • Cold sores
    • Genital herpes
    • Herpes zoster

    Valtrex can also be used for viral suppression in patients who are positive for HIV.

    Valtrex works by incorporating into an important virus enzyme that helps it to replicate. Once incorporated, viral particles cannot reproduce, and the body can suppress the infection. Valtrex does not cure herpes infection, but it can stop symptoms.


    The dosage of Valtrex depends on why it is being used:

    • Cold sores: Take 2 grams by mouth every 12 hours for one day
    • Genital herpes, initial episode: Take 1 gram by mouth twice daily for ten days
