Effectiveness
How Atovaquone Affects PatientsAtovaquone is a fat-soluble drug that resembles [ubiquinone]. It works by selectively affecting energy production in cells and process that create energy, such as ATP and pyrimidine biosynthesis. Atovaquone is believed to target a specific part of the cell (cytochrome bc1 complex, or complex III) in Plasmodia. Unlike other drugs, atovaquone does not have a high risk of reducing bone marrow production, making it a safe and beneficial treatment for those who have undergone bone marrow transplantation.
How Atovaquone works in the bodyWe don't know exactly how atovaquone works against Pneumocystis carinii, but it appears to target the cytochrome bc1 complex, which plays an important role in the electron transport chain. This action prevents important metabolic enzymes from working, which leads to the inhibition of nucleic acid and ATP synthesis. Atovaquone also has been shown to be effective against Toxoplasma gondii in laboratory tests.

Atovaquone Reviews: What are patients saying about Atovaquone?
4Patient Review
3/8/2020 I've been on this medication for a month now, and I'm still coughing up phlegm. Not sure how much longer this is supposed to go on for.
4Patient Review
2/16/2014 I'm not done with the treatment yet, so I can't give it a full five stars. But I have definitely felt an improvement within two weeks! And it's easy to measure how much you're taking- just use the water displacement method. Also, make sure to eat before taking it to avoid nausea.

Does atovaquone treat Covid?
"Results
Atovaquone significantly inhibited viral replication compared with placebo (P=.02). Among patients treated with atovaquone, the time to viral clearance was significantly shorter than among those treated with placebo (P This trial provides evidence that atovaquone inhibits viral replication and may be a promising treatment for patients with COVID-19 infection.
These studies found that atovaquone could be a good treatment for inhibiting viral replication. A trial was done with patients who had COVID-19 infection, and it was found that atovaquone significantly inhibited viral replication compared to placebo. The time to viral clearance was also significantly shorter among patients treated with atovaquone.
