Azithromycin Shows No Benefit for COVID-19 Symptoms
A UC San Francisco study has found that the antibiotic azithromycin was no more effective than a placebo in preventing symptoms of COVID-19 among non-hospitalized patients, and may increase their chance of hospitalization, despite widespread prescription of the antibiotic for the disease.
“These findings do not support the routine use of azithromycin for outpatient SARS-CoV-2 infection,” said lead author Catherine E. Oldenburg, ScD, MPH, an assistant professor with the UCSF Proctor Foundation. SARS-CoV-2 is the virus that causes COVID-19.
Azithromycin, a broad-spectrum antibiotic, is widely prescribed as a treatment for COVID-19 in the United States and the rest of the world. “The hypothesis is that it has anti-inflammatory properties that may help prevent progression if treated early in the disease,” said Oldenburg. “We did not find this to be the case.”
The study, which was conducted in collaboration with Stanford University, appears July 16, 2021, in the Journal of the American Medical Association.
The study included 263 participants who all tested positive for SARS-CoV-2 within seven days before entering the study. None were hospitalized at the time of enrollment. In a random selection process, 171 participants received a single, 1.2 gram oral dose of azithromycin and 92 received an identical placebo.
No Improved Recovery, Possible Harm
At day 14 of the study, 50 percent of the participants remained symptom free in both groups. By day 21, five of the participants who received azithromycin had been hospitalized with severe symptoms of COVID-19 and none of the placebo group had been hospitalized.
The researchers concluded that treatment with a single dose of azithromycin compared to placebo did not result in greater likelihood of being symptom-free.
“Most of the trials done so far with azithromycin have focused on hospitalized patients with pretty severe disease,” said Oldenburg. “Our paper is one of the first placebo-controlled studies showing no role for azithromycin in outpatients.”

My goodness this can be confusing. Our crisis with Superbugs really seems overlooked when even considering doing such a ridiculous study.
1 dose? And as a symptom reducer? Antibiotics? That’s again ridiculous, I think I get the idea but its risky to be throwing antibiotics at non infected (a actual bacteria or viral infection) sick person with a new smarter novel virus. No?
Typically there used not during the onset but the recovery of the virus. After its infectious contagious phase. What I understood is Ms use and over use of antibiotics are what contributes to Superbugs abilities,.
