How to read this: Each report says someone told FDA an event happened while a product was used. A report does not show the product caused it, and counts rise and fall with how many people report. Data from openFDA, FDA's public API. FDA says not to rely on it to make decisions about medical care and to treat every result as unvalidated; confirm against FDA's own record and the product labeling. Not medical or legal advice.
