No more DXM in Germany?

When I tried to buy some more cough lozenges today, I was told that the product I had been using (Silomat DMP) had been taken off the market. Apparently not only that, but all products containing the active ingredient dextromethorphan (DXM)—the pharmaceutical-technical assistant whom I spoke with said that there had been concerns about the cardiovascular system or something. So she recommended a cough syrup with herbal ingredients to me.
