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


    ENVARSUS XR (tacrolimus) is a medication prescribed for people who have received kidney transplants. It prevents organ rejection by suppressing the immune system.

    When people receive kidney transplants, their body does not recognize the foreign organ and tries to attack it. ENVARSUS XR prevents the activation of T-cells, which are cells of the immune system that attack foreign bodies.

    ENVARSUS XR requires careful monitoring by the doctor to ensure correct blood levels.


    The prescribing doctor will determine the appropriate dose. Take it exactly as prescribed by the doctor and do not adjust the dose.


    The active ingredient in ENVARSUS XR is tacrolimus.


    ENVARSUS XR and other forms of tacrolimus have many drug-drug interactions. Some of these interactions can be toxic, and some can decrease the drug levels until it is ineffective, which can cause organ rejection. Never start, stop, or change the drugs you are taking without talking with your doctor and pharmacist first.
