FREE! in Swedish Medicine (via Dan Ariely)

I recently learned of an interesting innovation in medical pricing coming from Sweden. This pamphlet from the healthcare authority states (translated): ”If you have a respiratory problem and you don’t take antibiotics for it during your first visit to the doctor, you have the right to a second visit within five days free of charge.

This approach is using the power of FREE! in an attempt to get people to reduce their use of antibiotics. But, I wonder if this approach might be too powerful, such that it will get people who should get antibiotics, not to get any. And, I also wonder if this approach will be particularly effective on people who have less money — which might not be ideal.
