DV 360 for Healthcare marketers

We're looking into starting programmatic as another avenue for marketing, and I'm looking into DV 360. The only thing that I'm not sure of though is if there are limitations similar to Google Ads when it comes to healthcare. Because we're in healthcare, I can't do any retargeting in Google Ads, so I was wondering if I'll have the same problem in DV360.

Are there any resources that I might be able to read on that would give me an idea to the answer here?
