The HCP group most likely to adopt the FreeStyle Libre system includes endocrinologists, primary care physicians, and diabetes nurse educators who encourage patient empowerment and are tech savvy. The initial target segment included those HCPs who saw their patients as partners.

The majority of the advertising rules & regulations that govern pharmaceutical advertising in Germany do not apply to the FreeStyle Libre system because it is a device. However, here are a few rules and regulations that German advertisements for the FreeStyle Libre system have to abide by:

- Advertising for medicinal products do not need to be approved in general or in specific circumstances. Furthermore, there is no obligation in Germany to provide competent authorities with advertising materials.

- Non-prescription medicines may be advertised to the general public, but as a general rule such advertisements relating to non-prescription products have to comply with the general provisions for advertising, i.e. they may not be misleading.

- The following promotional activities, among other things, are prohibited:

o Misleading advertising.

o Gifts and other advertising giveaways.

o Promotional activities aimed at the general public must not contain any advertising statements relating to prescription medicinal products or to (severe) diseases explicitly mentioned in the Healthcare Advertising Act.
