COVID-19 and Fluvoxamine

COVID-OUT Clinical Trial Results Announced 

  • Metformin, an inexpensive diabetes medication, proved superior to other existing medications in treating COVID-19 infection.
  • Metformin reduced serious outcomes for COVID-19 by 42% and over 50% when treated within 4 days of symptoms.
  • Neither ivermectin nor a low dose of fluvoxamine improved COVID outcomes.

Fluvoxamine for COVID

Fluvoxamine is an existing medication that has shown promise for treatment of COVID-19 infection. It is an SSRI (selective serotonin reuptake inhibitor) antidepressant that is commonly prescribed for obsessive-compulsive disorder.

Fluvoxamine’s ability to fight inflammation and block activation of platelets likely reduce the incidence of sepsis and blood clots that are common features of severe COVID-19 infection. 

Results from a small randomized, placebo-controlled study of fluvoxamine was reported by researchers from Washington University. In 152 adult outpatients with symptomatic COVID-19, none treated with fluvoxamine had worsening symptoms but 8.3% of the control group got worse.

Additional real-world experience supported the use of fluvoxamine. In an outbreak of COVID-19 at the Golden Gates Field Racetrack, physicians offered fluvoxamine to the 113 individuals testing positive. In total, 65 persons opted for fluvoxamine, and 48 opted for observation alone. None of the patients selecting fluvoxamine were hospitalized and all recovered, while six of those not taking the medication (or 12.5%) were hospitalized, many had lingering symptoms, and one died. 

The Together Trial is a randomized, controlled clinical trial conducted in Brazil that recently reported on the use of fluvoxamine for treatment of COVID-19. Of 1497 people with high-risk of serious COVID outcomes, 11% of those who received fluvoxamine required extended emergency room visits or hospitalization compared to 16% of those who received a placebo. For individuals who took most of the fluvoxamine doses, the death rate was reduced 91%.

A meta-analysis of 3 randomized clinical trials with 2196 participants reported that fluvoxamine had a high probability of being associated with reduced hospitalization in outpatients with COVID. Despite these studies, the US FDA declined to approve emergency use of fluvoxamine.
