## MedicationOrderDrugInput.line1 property [​](/content/docs/sdk/core.medicationorderdruginput.line1#medicationorderdruginputline1-property "Direct link to MedicationOrderDrugInput.line1 property"/index.html)

Dose text for a -keyed line, e.g. `"solution"`.

Optional, and only worth sending when the caller holds dose text *separate* from — a hand-entered form, say. Passing a full product label duplicates it in the description the vendor renders. When omitted, the vendor derives the dose from the formulation key or falls back to the sig.

**Signature:**

```typescript
readonly line1?: string;
```
