How to find reliable health info on the web

In order to evaluate health information, first ask yourself the following questions:

What is the purpose of the site?
How current is the site?
Who sponsors the site - a health institution or a company selling drugs, vitamins, herbal or alternative remedies?

The following offer reliable information:
www.webMD.com

www.MedicineNet.com (general health, one of the most popular)
www.Drugs.com (check out side-effects, drug interactions)
