Pills are pickups that can provide useful or inhibiting effects on Isaac.

Pills take up the same slot as cards and runes.
They are randomly chosen at the beginning of a run and assigned a color which remains static with that pill effect for the duration of the run unless the PHD item is picked up. As there are a limited number of pill colors, not every effect will appear in every run. In addition to that, one effect might also appear on two different pills. The set of pills for any given run is usually known as the pill rotation.
