More Danes are buying melatonin from pharmacies in Germany, DR reported. Melatonin, a sleep hormone produced in the brain, is a prescription drug in Denmark. However, in Germany, it can be bought over the counter as it is considered a dietary supplement. In its report, DR spoke to five German pharmacies, which all said melatonin was sold daily to Danish customers and that the number of customers has doubled in recent years. Due to problems that may arise from self-medication and inaccurate dosages, the Danish Medicines Agency has advised against buying melatonin without proper education about the drug.
