Fatigue, cognitive problems, post-exertional malaise (PEM) and postural orthostatic tachycardia syndrome (POTS) are common and debilitating symptoms after COVID-19. The pathophysiology of post-COVID is not well understood and there is no established biomedical treatment. Treatment options for post-COVID are thus much needed.

All interventional trials in our ClinicalTrials.gov extract that list Fluvoxamine as an intervention, across Long COVID / PASC (3). 1 is currently open to enrolment and 2 have completed. Read the OSMF evidence profile for Fluvoxamine for literature, mechanism and dosing context.
Intervention names are normalised from the registry's own arm labels, so the same compound can appear under a brand name, a generic name or a combination; check the full agent index for related entries.

Completed (2)
This clinical trial aims to test the effects of fluvoxamine as a treatment for Long COVID. Fluvoxamine is an FDA approved SSRI for Obsessive Compulsive Disorder (OCD), that has already had success in preventing hospitalization in patients with COVID-19 (STOP COVID and TOGETHER trials).
View on ClinicalTrials.gov ↗1. The purpose of this trial is to conduct a 2x3 factorial randomized trials, which efficiently allows the parallel conduct of three randomized trials to understand whether metformin, ivermectin, or fluvoxamine, is superior to placebo for preventing Covid-19 disease progression in non-hospitalized adults with SARS- CoV-2 infection. 2.

How do I join a clinical trial?
Open the trial's ClinicalTrials.gov record (the "View on ClinicalTrials.gov" button), read the Eligibility Criteria and Contacts and Locations sections, and contact the study team listed there. Trials only enrol at the sites shown in the record, so check whether a site is near you or whether the study is remote/decentralised. Your own clinician can help you judge whether a trial is a sensible option and may need to provide medical records.
What do the trial phases mean?
Early Phase 1 / Phase 1 studies test safety and dosing in a small group. Phase 2 studies look for a signal of benefit in a larger group and keep checking safety. Phase 3 studies are large confirmatory trials designed to show whether a treatment works well enough for approval. Phase 4 studies follow approved treatments after they reach the market. "Phase not applicable" is used by the registry for behavioural, device, rehabilitation and other non-drug interventions.
Does the Open Source Medicine Foundation run these trials?
No. OSMF does not sponsor, run or recruit for any trial on this page. We compile public registry entries from ClinicalTrials.gov so patients and clinicians can find them in one place. For questions about a specific study, contact the sponsor or study team listed on its ClinicalTrials.gov record.
