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.


GONAL-F is a prescription medication used in the treatment of infertility. It contains follitropin alfa, a synthetic hormone that stimulates the growth and development of ovarian follicles in women and can induce spermatogenesis in men when administered with hCG.

GONAL-F should be prescribed by a healthcare professional experienced in treating infertility. Before starting treatment, a thorough medical evaluation is necessary to rule out any underlying conditions that may affect fertility.

GONAL-F is available in a powdered form mixed with a sterile liquid before injection. It is administered subcutaneously (under the skin).

The active ingredient in GONAL-F is follitropin alfa, which is a recombinant form of follicle-stimulating hormone (FSH).


  • There are no known significant interactions.


Do not use GONAL-F if you are allergic to follitropin alfa, lactose, or any other ingredient in the medication.

Tell your doctor if you have a history of ovarian cysts, abnormal vaginal bleeding, thyroid or adrenal gland disorders, or pituitary gland tumors.

GONAL-F may increase the risk of multiple pregnancies, which can lead to complications for both the mother and the fetus.
