How this page is built

Everything on this page is copied from public ClinicalTrials.gov registry records — it is not written from memory, and nothing here describes how Methylene Blue works or whether it is effective. Each trial links to its own record so you can check it yourself.

This page is built automatically: a daily sync job reads the registry records behind our country trial registers, collects every trial that lists Methylene Blue (or a registered synonym) as a drug or biological intervention, and tabulates the registry fields directly. Placebos and generic comparators are excluded. There is no AI drafting and no per-compound editorial pass, and the page has not been clinically reviewed. The “last verified” date above is the timestamp of that sync, not a review date. Our general editorial approach is described in our editorial standards and corrections policy. The ClinicalTrials.gov data on this page was last retrieved on 10 Nov 2026. How every register is built: methodology · fixes we have made: corrections log.

Please verify before you rely on this. This page is general information for life-science and pharmaceutical professionals. It is not medical advice, and it has not been reviewed by a clinician — our editorial team holds life-science qualifications, not clinical ones. It is not exhaustive and may not reflect the most recent label change. Always check the official prescribing information (US Prescribing Information or EU SmPC) and speak to your doctor or pharmacist before acting on anything here. Drugs in the same class are not automatically interchangeable, and approvals, brand names and indications differ between the US, the EU/Ireland (EMA/HPRA) and other regions. Spotted an error?
