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.


Kuvan is used with a phenylalanine (Phe)-restricted diet to lower Phe levels in the blood in adults and pediatrics one month old and older and have hyperphenylalaninemia due to tetrahydrobiopterin-(BH4-) responsive Phenylketonuria (PKU).

  • 100 mg tablet

  • 500 mg powder for oral solution


Take Kuvan as directed by your doctor. Refer any questions or concerns to your doctor or pharmacist.

The dose of Kuvan depends on the patient’s age and weight.

Take Kuvan with a meal. Swallow the tablets whole or after mixing in a small amount of soft foods (i.e., applesauce or pudding) or dissolved in liquid (water or apple juice). Swallow the oral solution after mixing the powder in a small amount of soft foods or dissolving in recommended liquid.
