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.
Ibrance is a cancer medicine that interferes with the growth and spread of cancer cells in the body. Ibrance is used in men and women to treat HR-positive, HER2-negative breast cancer that has spread to other parts of the body. In postmenopausal women, Ibrance is given in combination with a hormonal medicine such as letrozole (Femara). In others, Ibrance is given together with fulvestrant (Faslodex).
Take Ibrance exactly as it was prescribed for you. Follow all directions on your prescription label and read all medication guides or instruction sheets. Your doctor may occasionally change your dose. Ibrance is given in a 28-day treatment cycle, and you may only need to take the medicine during the first 3 weeks of each cycle. Your doctor will determine how long to treat you with Ibrance.
