Medication Access# PRO

The Scripting app provides read access to the Medications a person tracks in the Health app, together with their logged dose events, using Health.queryMedications() and Health.queryMedicationDoseEvents().

Requires iOS 26.0 or later. On earlier systems both functions reject with an error.

This guide explains how to list a person's medications and how to read the doses they logged.

#Medications and Dose Events

• A medication (HealthUserAnnotatedMedication) is something the person tracks in the Health app. It carries a nickname, an isArchived flag, a hasSchedule flag, and a medication concept.
• A medication concept (HealthMedicationConcept) describes the medication itself: a stable identifier, a displayText name, a generalForm (such as "tablet" or "injection"), and relatedCodings (such as RxNorm codes).
• A dose event (HealthMedicationDoseEvent) is a single logged dose — taken, skipped, snoozed, or not interacted with. It links back to a medication through medicationConceptIdentifier.

#Permission

Both functions automatically ask the person to choose which medications Scripting may read. Access to a selected medication also covers its dose events; there is no separate dose-event permission. You can call Health.queryMedicationDoseEvents() directly without first loading the medication list.

The system may show the medication selection sheet again on later queries so the person can review their choices. Queries return only data for medications they share. An empty result can mean no medications were shared or no records match the query; it does not prove that reading was authorized. Closing the selection sheet can complete the query with an empty result. Handle request failures with try/catch; neither successful completion nor an empty result proves that access was granted.

#API Overview

Health.queryMedications(options?: {
  isArchived?: boolean
  hasSchedule?: boolean
  limit?: number
}): Promise<HealthUserAnnotatedMedication[]>

Health.queryMedicationDoseEvents(options?: {
  startDate?: Date
  endDate?: Date
  limit?: number
  strictStartDate?: boolean
  strictEndDate?: boolean
  sortDescriptors?: Array<{
    key: "startDate" | "endDate"
    order?: "forward" | "reverse"
  }>
  statuses?: HealthMedicationDoseEventLogStatus[]
  scheduledStartDate?: Date
  scheduledEndDate?: Date
  medicationConceptIdentifiers?: string[]
}): Promise<HealthMedicationDoseEvent[]>

#Example: Listing Active Medications

const medications = await Health.queryMedications({
  isArchived: false,
})

for (const item of medications) {
  console.log("Name:", item.nickname ?? item.medication.displayText)
  console.log("Form:", item.medication.generalForm)
  console.log("Scheduled:", item.hasSchedule)
}

#Example: Reading Today's Dose Events

const startOfDay = new Date()
startOfDay.setHours(0, 0, 0, 0)

const doses = await Health.queryMedicationDoseEvents({
  startDate: startOfDay,
  endDate: new Date(),
  sortDescriptors: [{ key: "startDate", order: "reverse" }],
})

for (const dose of doses) {
  console.log("Status:", dose.logStatus)       // "taken" | "skipped" | ...
  console.log("Dose:", dose.doseQuantity, dose.unit.unitString)
  console.log("When:", dose.startDate)
}

#Example: Doses for a Specific Medication

Use a medication's identifier to fetch only its doses:

const medications = await Health.queryMedications({ isArchived: false })
const target = medications[0]

const doses = await Health.queryMedicationDoseEvents({
  medicationConceptIdentifiers: [target.medication.identifier],
  statuses: ["taken"],
})

console.log(`Logged ${doses.length} taken dose(s) of ${target.medication.displayText}`)

#Notes

• Health.queryMedications() returns HealthUserAnnotatedMedication instances; Health.queryMedicationDoseEvents() returns HealthMedicationDoseEvent instances.
• scheduledDate and scheduledDoseQuantity are only present for scheduled dose events (scheduleType === "schedule"); they are null for as-needed doses.
• A dose event's medicationConceptIdentifier matches the identifier of the medication's concept, so you can group doses by medication.
• These APIs are read-only — medications and dose events are managed by the Health app and can't be created from a script.

#Summary

1. Use Health.queryMedications() to list the medications a person tracks.
2. Use Health.queryMedicationDoseEvents() to read logged doses, filtered by date, status, schedule window, or medication.
3. Link the two with HealthMedicationConcept.identifier / HealthMedicationDoseEvent.medicationConceptIdentifier.
