Reuters reports that Abbott Laboratories has instructed its sales representatives in India not to give gifts to doctors, who are prohibited by local law from accepting them, a practice that has been used as a bargaining chip by companies wanting a piece of the country’s burgeoning healthcare market. Public health experts say gift-giving leads to dangerous over-prescribing and unnecessary use of expensive medications when cheaper versions are available. That can be a significant burden for the 400 million people in India who live on less than $1.25 a day.
