Directive new drug warning

EXPERIMENTAL

Survey contains information about when the drug was approved by the FDA (2009)and a directive warning (i.e., stating the issue and why it matters) for new drugs. This directive warning mentions that serious drug side effects may emerge only after the drug is already on the market, and the reader should ask their doctor there is an available drug with a longer track record.

Other: Presentation of information about drug approval and level of warning

Non-directive new drug warning

EXPERIMENTAL

Survey contains information about when the drug was approved by the FDA (2009) and a non-directive warning (i.e., just stating the issue) for new drugs. This non-directive warning mentions only that serious drug side effects may emerge only after the drug is already on the market.

Other: Presentation of information about drug approval and level of warning
