# Searching for drugs/vaccines with WHODrug

VigiFlow allows you to filter reports based on drugs or vaccines.

Navigate to the “**`Drug/Vaccine`**” tab under the advanced filters to filter WHODrug. The following filtering options are available:

* **`Drug name (WHODrug)`**: Type in the name of the drug to search for reports with that drug. Both trade name and active ingredient can be entered.
* **`Active ingredient(s) (WHODrug)`**: A search on active ingredient will retrieve all reports with this active ingredient, regardless of whether coding was done on trade name or active ingredient.
* **`Batch number`**: Enter the batch number of both medicines and diluents.
* **`ATC code`**: For a broader search, enter the ATC code of interest.
* **`Indication (MedDRA)`**: Reports can also be filtered by indication.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://support.who-umc.org/vigiflow/find-relevant-reports-using-filters/searching-for-drugs-vaccines-with-whodrug.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
