One thing I did notice in the Fox video was that both the doctors took time to warn about the potential for significant cardiac risk from these drugs. One mentioned doing a baseline EKG and frequent follow up EKGs to watch for changes. They both know that this risk can develop very quickly with these drugs, long term therapy is not required. There are many reports from recent hydroxychloroquine usage in Covid of having to stop the drug because of changes, including some in the Fox segment. I mention this now because in an earlier thread somebody claimed that the FDA said it only was a risk after six months, because that person did not understand the difference between no risk before six months, and increase risk after six months. What the FDA clearly said was risk increased with duration of medication. It never said there was no risk with shorter duration. But the author of that post misunderstood what was written and claimed that posters who warned about cardiac risk were wrong.
Your google fu is not quite up to the task.
