Do adverse drug reactions have to have a clear causal relationship before they can be reported?

No. Determining the causal relationship between a drug and a suspected adverse reaction is sometimes very difficult and takes a long time. Generally, it can be reported as long as it is suspicious. Report adverse drug reactions that have occurred in a timely manner. The national drug regulatory department will analyze and evaluate the collected report data. Based on the evaluation results, timely measures can be taken to release information in various ways to limit or stop the production, sale and use of relevant drugs to avoid The recurrence of the same drugs and the same adverse reactions will protect the drug safety and health of more people, and even protect the safety and health of the next generation.
