Important Risk and Safety Information About DaTscan

DaTscan™ (Ioflupane I 123 Injection) for Intravenous Use, CII

DaTscan™ is a radioactive drug that is injected into your bloodstream to help take pictures of areas of your brain using a special camera (called a SPECT). If you are an adult with a movement difficulty that may be a parkinsonian syndrome (PS), your doctor may decide to conduct a SPECT using DaTscan contrast, along with other medical tests, to help decide if your movement difficulties are due to PS or a similar condition known as essential tremor. Some types of PS are Parkinson’s disease, multiple system atrophy, and progressive supranuclear palsy.

You should not take DaTscan if:
  • You are sensitive to iodine or any of the components of DaTscan; your doctor can help you understand what these ingredients are
  • DaTscan can cause a reaction. When this occurs, it is usually a skin rash or itching
  • Before you receive a DaTscan injection, your doctor will give you a medication that will reduce the radioactivity going into your thyroid gland
The most common side effects of DaTscan:
  • Headache, upset stomach, a sensation of motion, dry mouth, or dizziness has occurred in fewer than one out of every 100 patients
What you should know about taking DaTscan with other medications:
  • Some drugs may interfere with the DaTscan-enhanced picture. Be sure to tell your doctor what drugs you are taking so that he or she can decide whether you should stop any of them for a period of time before using DaTscan
  • Always talk to your doctor if you have any questions about SPECT imaging or the use of DaTscan
