Depressed COVID Patients Respond Much Better Than Expected to SSRI Antidepressants

Antidepressant Medication Concept

A pilot study indicates that depressed patients who have experienced COVID respond more favorably to standard antidepressants compared to those who have not had COVID.

The COVID pandemic has led to a significant increase in mental health problems. Now, in some good news, a pilot study has shown that depressed patients who have suffered from COVID respond better to standard antidepressants than do people who have not had COVID.

Around 40% of COVID-19 sufferers report the development of depression within 6 months of infection. The inflammation caused by COVID is believed to be the main reason for the development of depression. Now new research has shown that around 90% of patients who have suffered from COVID respond to SSRIs, significantly more than would be expected.

This work is presented at the ECNP Conference in Lisbon, and has been published in the peer-reviewed journal European Neuropsychopharmacology. Lead researcher Mario Mazza MD, San Raffaele University, Milano said:

“We know that COVID has led to an epidemic of mental health problems. Post-COVID depression is a serious issue, with around 40% of COVID patients developing depression within 6 months of infection. But this study indicates that patients who have had COVID have a better chance of managing their depression than we thought.”

The researchers, from Professor Francesco Benedetti’s Laboratory of Psychiatry and Clinical Psychobiology at San Raffaele Hospital in Milano, treated 58 patients who had developed post-COVID depression with SSRIs (Selective Serotonin Reuptake Inhibitors) such as sertraline, paroxetine, fluvoxamine, and citalopram. Normally around a third of patients don’t respond to SSRIs, but the team found that that 91% of those with post-COVID depression responded to treatment within 4 weeks (response was measured using the standard Hamilton Depression Rating Scale: a patient was considered to have responded if they showed a 50% reduction in the scale after 4 weeks of treatment).  

Dr. Mazza continued:

“This is a pilot study, but it does indicate that post-COVID depression is treatable. We would normally have expected around 40 of the 58 patients to have responded positively to treatment, but in fact we found that 53 of the 58 responded. Considering the anti-inflammatory and antiviral properties of SSRI, we hypothesized that post-COVID depression triggered by infection and sustained by infection-related systemic inflammation could particularly benefit from antidepressant treatment. We are now taking this work forward to a larger scale trial. We also want to investigate whether SSRIs can also help with other post-COVID symptoms, such as cognitive impairment and fatigue, and to look at the role of inflammation in post-COVID depression.”

Commenting, Dr. Livia De Picker MD PhD (University of Antwerp, Belgium) said this study is of particular importance to the large group of patients and clinicians who are currently dealing with long COVID syndromes.

“Long COVID consists of a combination of persistent physical, psychological and neurocognitive symptoms after COVID-19 infection, which may present very different in different individuals. Even if we still do not understand all the causes of long COVID, this study indicates post-COVID depressive symptoms respond very well to serotonergic antidepressants. This does not come as a surprise to me, as recent studies have pointed out such compounds may also protect patients against severe COVID-19 illness and several antidepressants are currently under study as COVID-19 treatment options. I hope the current findings will prompt further research into the mechanisms through which antidepressants can help against both acute and long-term COVID-19 complaints. Most importantly, these findings stress the importance of adequate screening and treatment of mental health symptoms in patients who suffer from persistent health problems after having been exposed to COVID-19.

  1. Just keep bowing down to your government overlords and here, take this pill to make you subserv… wait… I mean, happy!

  2. Psychoactive drugs are dangerous cruel and are tools of touture.

    Psychiatry is not a science but a ideological position that changes as time goes on.

    Tis a justification for tourture.

    They will go down in the history books as the 20th and 21st centurys witch hunters and burners.

    Vulger insidious odious be they

  3. SSRI and SNRIs are Hell drugs, PSSD exists and its the most horrible condition on earth..
    Please stop prescibing this hell and research for a cure.. i cant do this no longer
