How we gather our data?

Healthcare data is obtained from a number of sources including the Food and Drug Administration (FDA). This information is aggregated and used to produce personalized reports that patients can reference.

The information that eHealthMe collects includes:

  • Side effects (including severity and how people recover from them)
  • Associated conditions or symptoms
  • Drug effectiveness
  • Demographic data regarding drug use

How the study uses the data?

The study is based on niacin and magnesium (the active ingredients of Niacin and Magnesium, respectively), and Niacin and Magnesium (the brand names). Other drugs that have the same active ingredients (e.g. generic drugs) are not considered.

What is Niacin?

Niacin has active ingredients of niacin. It is often used in high blood cholesterol. (latest outcomes from Niacin 7,453 users)
