Hydroxychloroquine: ALL doctors can use it (red, blue, purple, green). Oh gosh, it's a conspiracy that the FDA wants it tested like all other drugs. It does have some serious side effects like the heart rhythm issue that is killing people. It's good to figure out if it is an issue with patients who have heart disease, possibly due to a medication the patient is taking or possibly patients who have high blood pressure. All doctors can use it in any hospital. The only thing they are saying now before it is approved is to do it under a doctors care. It makes sense.
