Summary

This study aims to find out why some people have bad reactions to medicines while others don't. Researchers will collect samples from 7,000 children and adults who have had a bad drug reaction, as well as from those who haven't. By comparing their genes, they hope to create guidelines that help doctors prescribe the right dose for each person, reducing the risk of harmful side effects.
