The Danish Medicines Agency is like a big group of people who check and make sure that all the medicines that people take in Denmark are safe and work properly. Imagine you have a toy, and you want to make sure it doesn't break or hurt someone when they play with it. The people at the Danish Medicines Agency do the same thing with medicines! They test and inspect the medicines to make sure they are safe and will not cause harm to the people who take them. They also make sure that the instructions for taking the medicine are clear and easy to understand. This way, if you ever need to take medicine for an illness or pain, you can trust that it will help you feel better and not make you sick.
