Florbetapir F 18 is a radioactive agent that allows images of specific organs in the body to be detected by a PET (Positron Emission Tomography) scan.

Florbetapir F 18 is used together with a PET scan to detect the amount of plaque in the brain. Plaque is a build-up of certain proteins and diseased nerve cells that is often found in the brain of a person who has signs of Alzheimer's disease or other causes of dementia.

Florbetapir F 18 may also be used for purposes not listed in this medication guide.

Receiving a radioactive agent such as florbetapir F 18 may increase your long-term risk of developing cancer. Talk with your doctor about your specific risk.

Florbetapir F 18 is injected into a vein by a healthcare provider.

florbetapir F 18 is usually given 30 to 50 minutes before your PET scan.

Usual Adult Dose for Positron Emission Tomography Imaging:

370 MBq (10 mCi), maximum 50 microgram mass dose, intravenously as a single bolus in a total volume of 10 mL or less

Comments: The injection should be followed with an intravenous flush of 0.9% sterile sodium chloride.

Use: PET imaging of the brain to estimate beta-amyloid neuritic plaque density in adult patients with cognitive impairment who are being evaluated for Alzheimer's Disease (AD) and other causes of cognitive decline.
