The phrase comes from the mandatory disclaimer heard at the end of German television and radio adverts for medicines, usually spoken very quickly: zu Risiken und Nebenwirkungen lesen Sie die Packungsbeilage und fragen Sie Ihren Arzt oder Apotheker. Clips isolating part of that warning, shortened here to zu nebenriziken, began circulating on soundboards as a standalone reaction. Its appeal online is the recognisable bureaucratic tone, which German speaking viewers instantly associate with medicine commercials, even when it is pasted onto completely unrelated jokes, edits and parody adverts.
