The first so-called digital pill has been approved by the Food and Drug Administration. It’s a version of the antipsychotic drug Abilify and contains a tiny sensor that will send a signal to a patch the user is wearing.

Advocates say the digital version will keep patients from forgetting to take their medicine.

Others are concerned about potential Big Brother components related to ingesting something that could transmit information externally.

Glenn Cohen is a bioethicist and a law professor at Harvard. The digital version of Abilify is called Abilify MyCite.
