In the latest flap over pharmaceutical promotion, a South Korean drugmaker is being chastised by an organization of pharmacists for hiring a popular girl group to promote a painkiller. Why? There are concerns that the headache reliever may be abused by teenagers who have been using the medicine inappropriately to lose weight, according to ChannelNewsAsia.

The Korean Pharmaceutical Association wants Samjin Pharmaceuticals not to feature Girl’s Day in upcoming ads for the top-selling Geworin painkiller. Their hit song, ‘Twinkle, Twinkle,’ will also be featured in the ads (curious? you can watch the group perform the song here).

The KPA believes using the group to market the drug might send the wrong message to youngsters that Geworin is perfectly safe, which “may encourage them to abuse the product.” In a recent statement, the KPA notes there have been reports of youth abusing Geworin - taking enough of it to experience side effects like dizziness and vomiting - so they could leave school early, CNA writes.

The pharmacy group worries that some youngsters are taking Geworin “for diet purposes,” because the pill can induce vomiting, diarrhea as well as nausea, which in turn suppresses appetite. KPA also notes that regulations prohibit administering drugs to anyone younger than 15 years old, which is the majority of the Girl’s Day audience.

KPA, CNA writes, is “seriously concerned” and may try to block Geworin from being sold in pharmacies if Samjin proceed with the ads. What does the drugmaker think of all this? Samjin will air the ads, but promised to conduct research to investigate the issues raised by KPA and disclose results next year. Meanwhile, plenty of teens will see the ads.
