It depends on what information is available to establish trends and then subsequently determining causation. Formulation of all possible solutions must rest on evidence and we have a lack of information in that regard.
If a drug company comes out with a drug and the drug ends up being related to an abnormal number of fatalities, you can bet that federal agencies would research and provide grants for research to gather every bit of information available. What were the circumstances, what was the patient’s condition, what happens with similar drugs, what other drugs might be involved, etc... then a determination would be made. Do you pull the drug altogether, do you change the dosage, is it interacting with other drugs so now it’s contraindicated for patients on the drugs it interacts with, is there a certain patient population that the drug is contraindicated for? All are possibilities and all might be implemented based on relevant INFORMATION GATHERING.
I know for certain the FDA wouldn’t throw their hands up and say “oh well, the patients that are taking these drugs just need to be responsible for their own actions” and leave it at that. That line of thinking is so lazy and ineffective.
