For years, we at Cross4Channel have relied on WhatsApp to make patient communication, professional dialogue, and digital services more efficient and modern. Now this service has its own name: Comviira.

With Comviira, we combine our experience from numerous projects into a clearly defined product – data protection compliant, adaptable and ready for immediate use.

What is Comviira?

Comviira is an interactive WhatsApp service that goes far beyond the capabilities of traditional channels. Users can actively access content, ask questions, and interact directly with services – all in compliance with the German Health Act (HWG), GDPR, and pharmaceutical requirements.

Typical areas of application

 🧑‍⚕️Patient communication

In addition to general patient communication, WhatsApp offers Comviira, an ingenious and extremely popular social media channel for existing patient service programs in the form of a WhatsApp profile.
Patients can:

• Retrieve information automatically or specifically
• Verify yourself by code, PZN or batch number
• chat directly 1:1 with the service center

This makes contact not only more convenient, but also more secure and personal.

👨‍⚕️ HCP communication

With Comviira, healthcare professionals can be addressed in a targeted and legally secure manner – for example via:

• DocCheck verification
• One-time codes or congress access
• Individualized content (videos, PDFs, links)
• 1:1 chat function for field support or MSL communication

Why Comviira?

• Profile that is directly integrated into the private chat profiles
• Proven in practice: In use for years, now under its own brand
• Data protection secure: Hosting in Germany, GDPR compliant
• Modular & expandable: From standard solutions to API integration
• HWG compliant: Content can be controlled via verification mechanisms
