Clinic for general medicine and addiction medicine

Welcome to Praxis Lyonn. Together with my team, I welcome you to my clinic for general medicine and addiction medicine. We see ourselves primarily as a general medicine practice, and particularly care for the needs of people with illicit substance use and addiction. Our doors are open to everyone, who comes to us for medical care, with respect and tolerance towards all human beings, especially those who are often disregarded by the general society because of their substance abuse.

We cooperate with Notdienst Berlin e.V. in mutual rooms and jointly operate the A.I.D. Kreuzberg (Ambulanz für Integrierte Drogenhilfe = clinic for integrated addiction treatment), the first Berlin outpatient clinic of its kind.

Latest clinic news

Update Corona vaccinations
Even though vaccination without prioritization will be generally possible in Berlin from Monday, May 17th, 2021, we will not be able to offer this service to new patients. We will have to work through our internal list of prioritization first, and we will announce on this web site, if and when there will be openings. Please do not call us or send us emails regarding vaccination appointments. Thank you for understanding.
Corona vaccinations
Unfortunately we can offer Corona vaccinations only to patients, who are currently already receiving treatment with us - We are not a Corona focus practice.
In case of Corona suspicion
At this time, we ask that you do not enter our office if you are experiencing one or more of the following symptoms: Fever, sore throat, headache, cough, runny nose, loss of taste and/or smell, and gastrointestinal distress. Please call us first and ask to be connected to one of the doctors to clarify how you should proceed.
