"We are further concerned by the confusion that may result from various state government agencies and boards issuing emergency rules limiting or restricting access to chloroquine, hydroxychloroquine or other emerging therapies or requiring new procedures for physicians and other healthcare professionals and patients. If these bodies promulgate new rules, we urge that they emphasize professional responsibility and leave room for professional judgment. We further urge that patients already on these medications should not be impacted by new laws, rules or other guidance. In a time of national pandemic, now is not the time for states to issue conflicting guidance, however well-intentioned, that could lead to unintended consequences. We applaud the ongoing efforts to conduct clinical trials and generate evidence related to these and other medications during a time of pandemic. We are also encouraged that some pharmaceutical manufacturers are increasing production of high-demand medications as well as supplying them for use in clinical trials."
