The medicines made for coughing usually contain Dextromethorphan or DXM. DXM has been used in this type of medicine as an active ingredient but it’s very dangerous, in fact, it can be fatal for babies and children (this also counts for young adults). This ingredient is one of the main reasons for emergency room visits and drug-related deaths in the young adults, and all parents should be warned about the fact that 10% of the children don’t have the needed enzymes to metabolize DXM effectively, which leads to very dangerous circumstances.
