# MedicationRequest _search

`POST /MedicationRequest/_search`

This resource contains a list of a patient’s current prescribed medications, as documented by one organization. What this doesn’t contain: any details about how much a patient has taken of what they were prescribed.

You can review, retrieve, or create a list of current medications for a patient. 

> **Supported fields and schema examples**
>
> We support any valid FHIR field. However, we only display fields we’ve defined in our schema, which are usually based on what’s included in the U.S. Core profile. We recommend relying on U.S. Core requirements. 
>
> Our schema examples show the shape and possibility of each FHIR resource; they aren’t code for real-time API calls. We don’t currently recommend copying and pasting these schema examples for your API calls. [Consider reviewing FHIR API actions](/fhir-api-actions) for realistic examples for particular use cases.

### \_search

Query for a list of current medications for a patient. [Review tips for medication searches](https://docs.redoxengine.com/permalink/5ViW1sFKmaQD0njGTnjWA7).

> **Flexible FHIR queries, different query parameters**
>
> FHIR queries are a flexible option with parameters to refine your search. The response returns a bundle of resources, known as a `searchset` bundle type. [Learn about bundles and bundle types](https://docs.redoxengine.com/permalink/23Q1Oku3NdxxvwYnQGJVrg) in our FHIR glossary.
>
> We only note which query parameters are required _if you’re querying a FHIR server directly_. Remember that Redox (i.e., data on demand) isn’t a FHIR server, and your connection may not be either.
>
> _Query parameters will vary between sites._ Work with your connection to find out which query parameters they require for a successful search.

###### Data on demand requirements

For data on demand searches, you must include this query parameter: 

- FHIR resource ID for `Patient` resource ([learn about FHIR references](https://docs.redoxengine.com/basics/redox-fhir-api/fhir-glossary/#reference) or [review HL7's docs on references](https://build.fhir.org/search.html#reference))

The start may be in the past, and the end date in the future, which means that period is expected/planned to end at that time. |
| `entry[] (MedicationRequest).resource.dispenseRequest.numberOfRepeatsAllowed` | number | No | An integer indicating the number of times, in addition to the original dispense, (aka refills or repeats) that the patient can receive the prescribed medication. Usage Notes: This integer does not include the original order dispense. This means that if an order indicates dispense 30 tablets plus "3 repeats", then the order can be dispensed a total of 4 times and the patient can receive a total of 120 tablets.

| `entry[] (MedicationRequest).resource.dispenseRequest.performer` | object | No | Indicates the intended dispensing Organization specified by the prescriber. Must be a resource of type `Organization`. |
| `entry[] (MedicationRequest).resource.dispenseRequest.performer.reference` | string | No | A reference to another resource. This is typically either a relative reference which includes the resource type and ID, or an internal reference which starts with `#` and refers to a contained resource. |
| `entry[] (MedicationRequest).search` | object | Yes | Information about the search process that lead to the creation of this entry. |
| `entry[] (MedicationRequest).search.mode` | string | Yes | Identifies the MedicationRequest as matching the search parameters. Value: match |
| `entry[] (Other).search` | object | Yes | Information about the search process that lead to the creation of this entry. |
| `entry[] (Other).search.mode` | string | No | Why this entry is in the result set - whether it's included as a match or because of an _include requirement, or to convey information or warning information about the search process. Possible values: match, include, outcome - why this is in the result set |
