What is a generic medicine?
All medicines have two names:
brand
generic
For example:
Brand:
Prozac
Generic:
Fluoxetine
Each medicine has a generic name to describe the ingredients. Drug companies give their medicines brand names.
Is there a difference between brand name and generic drugs?
Usually, the difference is in the name and the price of the medicine. A generic drug must have the same active ingredients as the brand name drug in order for the Food and Drug Administration (FDA) to approve the generic. The generic drug must also be the same strength, and the same dosage form (pill, liquid, shot) as the brand name.
Sometimes, generic medicines have different fillers or additives that may cause slightly different effects. If you have questions or concerns about taking a generic medicine, be sure to let your doctor know.
Generic medicines might not look like brand name medicines. The way the generic medicine looks does not change the way it works in your body. Remember, never assume that a medicine that looks different is "generic." Double check with the pharmacist before you leave the pharmacy. If you have questions about the way your medicine looks, ask your pharmacist to explain.
How do I get a generic medicine?
Ask your doctor or pharmacist if an equivalent generic form of your brand name medicine is available. You can also discuss the difference in price between the generic and brand name medicine.
Not all medicines are available in a generic form. Your doctor may prescribe a medicine that is available only in the brand name form.
What if I do not want generic medicine?
Share your concerns with your doctor. If you both agree that a generic medicine is not the best choice for you, ask your doctor to write, "Do not substitute" on your prescription. This lets your pharmacist know that only the brand name is to be used in filling the prescription. Depending on your health plan, you may have to pay more for, or cover the entire cost of, the brand name.
