The short answer

The responsible person for a dietary supplement β€” the manufacturer, packer or distributor whose name is on the label β€” must send every serious adverse event report it receives about the product used in the U.S. to FDA within 15 business days, on a MedWatch form (21 U.S.C. 379aa-1). Records of all adverse event reports must be kept for 6 years.

And every supplement label needs a domestic U.S. address or domestic U.S. phone number where consumers can report β€” a website or email alone is not enough.

Setting up adverse event handling

  1. 1Put the U.S. contact on the labelStreet address or P.O. box with city, state and ZIP, or a U.S. phone number with area code. FDA recommends a clear statement telling consumers they can report serious adverse events there.
  2. 2Route every reportFrom the U.S. contact, Amazon, your website, distributors and social media to one person who decides if it is serious.
  3. 3Submit serious reportsWithin 15 business days on MedWatch Form 3500A, with a copy of the label.
  4. 4Send follow-upsNew medical information received within 1 year, within 15 business days.
  5. 5Keep records 6 yearsSerious and non-serious reports alike, available for FDA inspection.

Example: a supplement brand from Australia

An Australian brand sells a pre-workout powder on Amazon US. Its label had only an Australian phone number and a website, so it adds a U.S. phone number and the line β€œReport serious adverse events to the number above.” When a customer reports being hospitalized with a fast heart rate after use, the brand files a MedWatch report within 15 business days, attaches the label and keeps the record for 6 years.
