Overview.

Prologue MD provides telehealth medical services through licensed physicians. The information on this website is for educational purposes and is not a substitute for professional medical advice, diagnosis, or treatment.

Always seek the advice of your physician or other qualified health provider with any questions you may have regarding a medical condition. Never disregard professional medical advice or delay in seeking it because of something you have read on this site.

02

About our protocols.

The medications prescribed through Prologue — including metformin, acarbose, NAD+, sermorelin, low-dose naltrexone, and testosterone — may be prescribed off-label. This means they are FDA-approved for specific indications but are being used by your physician for a purpose not included in the FDA-approved labeling.

Off-label prescribing is a legal and common practice in medicine, supported by clinical evidence reviewed by your physician. Your physician will discuss this with you during your evaluation and will only prescribe a medication if they determine it is clinically appropriate for you.

03

About our content.

The educational content on this website and in our guides is intended to help you make informed decisions about your health. It is not medical advice. The information presented reflects current published research, which is evolving.

We make every effort to be accurate and to distinguish between established evidence and emerging science. Where evidence is preliminary or contested, we say so. Where we don’t yet know something, we say that too.

04

About results.

Individual results vary. Prologue does not guarantee specific health outcomes from any protocol. The effectiveness of any treatment depends on individual factors including genetics, health history, lifestyle, and adherence to the prescribed protocol.

05

About emergencies.

Prologue is not an emergency medical service. If you are experiencing a medical emergency, call 911 or go to your nearest emergency room immediately.

Our physicians respond to clinical questions within 24 hours. For urgent but non-emergency clinical questions, contact your primary care physician or visit an urgent care facility.
