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.


Gastrofil is a prescription drug used to reduce the risk of infections in individuals undergoing immune-suppressive therapies to treat different types of cancers. It is indicated for patients with non-myeloid malignancies at a notable risk of febrile neutropenia but can also be used for acute myeloid leukemia (AML), following bone marrow transplantation, peripheral blood progenitor cell (PBPC) collection and therapy, severe chronic neutropenia, and HIV infection.

Grastofil has the same structure as a naturally occurring hormone called granulocyte colony-stimulating factor (G-CSF). Grastofil increases the production of white blood cells within the bone marrow.


The dosage varies based on the disease being treated and the patient's characteristics.

Use Grastofil exactly as directed by the doctor, and do not change, stop, or start therapy without discussing with your doctor.

Grastofil is available in prefilled syringes for easy administration.


The active ingredient in Grastofil is filgrastim.


  • Grastofil has no known drug-drug interactions


Use caution if you have a history of latex allergy because the pre-filled syringe contains natural latex. Use an alternative treatment if needed.

Tell your doctor if you have a history of sickle cell disease before starting this drug.

Tell your doctor immediately if you have abdominal or shoulder pain. This type of pain may be an indication of an enlarged spleen and impending splenic rupture, which is a medical emergency.
