FDA Testosterone Warnings

  • January 2014: The JAMA and PLoS One studies prompted the FDA to announce a an investigation of low-T therapies and their potential cardiovascular side effect.
  • June 2014: The FDA orders new blood clot warnings for prescription testosterone treatments, specifically for venous blood clots such as pulmonary embolism and deep vein thrombosis. The agency noted that the drugs’ labeling already included a warning regarding blood clots associated with polycythemia. However, regulators determined that a more general warning was needed due to reports of venous blood clots occurring in the absence of the condition. Read More
