How do I get to medications in Health.app? In this MacWorld article it shows a screenshot of Health.app with a section for medications but I can't find it in my Health.app. Was this functionality moved or removed at some point?
You cannot track medications in the Health app in the way you're describing. HealthKit does not have any medication data types. It's possible those screenshots were from an early/preview version of the Health app, but that feature definitely didn't make it into any shipping versions of Health.
