We ask if patients are being prescribed too many medicines. Confusion and lack of research, says one physician, can be a culprit in some cases where patients are handed prescriptions for medicines which are not necessary for the improvement of their overall health. Commercial influence from pharmaceutical businesses is seen as another factor in overmedication - so we speak to a representative from the pharmaceutical industry about who is responsible for educating patients and doctors about medicines, and how information can be improved. Also, 'the pill' could be a thing of the past, as an app called Natural Cycles becomes approved for use as a contraceptive - using body temperature to see when a woman is most fertile.
