What services do you offer at the Lyonn practice?

We offer comprehensive general and addiction medical care, with a focus on opioid substitution and diamorphine substitution.

How can I schedule an appointment at the Lyonn practice?

If you are already a patient at our practice or have an acute illness, you can simply come in without an appointment up to 30 minutes before the end of our daily office hours. To be admitted to the substitution program or for consultations regarding addiction medicine, please schedule an appointment by phone, email, or via our online form.

What do I need to bring to my first appointment?

Please bring your health insurance card, a list of your current medications, and any relevant previous medical records. This helps us prepare for your treatment as effectively as possible. Upon admission to the substitution program, we require a €10 deposit for the prescription fee.
