Determining whether health information on the Internet is accurate and reliable can be difficult, even for practicing physicians. Professional appearing sites may contain inaccurate information, or may be biased towards commercial interests that support the site. Meanwhile, unprofessional appearing sites may potentially contain accurate information.

There are several keys to finding and using accurate health care information on the Internet:

• Discuss information that you find on the Internet with your physician., who can help you better understand the information and help determine if it is accurate. Bring hard copies with you to your visit if you have a specific question about a site or information contained on it.
  
  
• Look for information on sites from credible sources including your physician's site, medical societies, government agencies, and university health centers.
  
  
• A site that is linked to a credible site could potentially have inaccurate information, as the organization that maintains a site cannot control information on sites to which they link, and these sites are subject to change.
  
  
• Ask your physician to recommend sites for your condition.
  
  
• Read all health information critically, and be aware that potential inaccuracies may exist.

• Keep your passwords protected, and do not share your accounts with family or friends.
