Frequently Asked Questions

Is it really free?

Yes, forever. No signup, no API key, no usage limits. Just copy the embed code and paste it into your site. We maintain the tool and database so you don't have to.

Can I customize the styling?

The widget inherits iframe isolation, so it won't conflict with your site's CSS. If you need custom branding (your logo, colors, or domain), contact us and we can discuss a white-label version.

Does it collect any user data?

No. The entire tool runs client-side in the browser. Zero tracking, zero cookies, zero analytics. No data leaves the user's device. We do not collect medication lists, search queries, or any personal information.

How many drugs and interactions are covered?

The database includes 108 of the most commonly prescribed medications in the US and 94 clinically significant interactions sourced from FDA labels and NIH DailyMed. We update the database periodically as new interactions are identified.

Will it slow down my website?

No. The widget is a single, self-contained HTML file with no external dependencies (aside from the Inter font). It loads inside an iframe, so it cannot block your page rendering. Typical load time is under 200ms.

Can I use it on a commercial site?

Yes. The only requirement is that the "Powered by OmniRx" branding bar at the bottom remains visible. You may use it on ad-supported, affiliate, or commercial pages.
