As COVID-19 surges around the world, scientists are desperately racing to find a treatment for it— and hopefully a cure for it as well. So far, one of the most promising (but not officially approved) types of treatment are antimalarial medicines. Of these, two medicines are being researched and considered more than others for coronavirus: chloroquine and hydroxychloroquine, two antimalarials with potentially hazardous side effects.
Hydroxychloroquine is the “less toxic” of the two, but it still has many concerning side effects, too. Pending approval as an official coronavirus drug, the public has a lot of questions about it. Like: how does hydroxychloroquine work? Will it fight coronavirus? Is it safe? Should you take it?
Though some studies suggest it could work great against coronavirus, we’re still mostly in the dark about it for now—especially when it comes to its safety.
Nevertheless, here are some facts about hydroxychloroquine to consider before it’s officially (potentially) given approval for COVID-19 and whether you should take it or not.
What is hydroxychloroquine?
Hydroxychloroquine is a pharmaceutical made from quinine. Quinine is a natural but powerful alkaloid extracted from the bark of the chinchona tree, a South American plant. Quinine has been used to treat malaria, a very dangerous and possibly life-threatening fever. Quinine pharmaceutical medicines revolutionized the fight against malaria when they were first developed in the early 20th Century.
Quinine medicines are considered “essential medicines,” meaning they must be manufactured and made accessible to everyone (especially when very effective against a widespread disease). They have anti-inflammatory, anti-parasitic, and antimalarial properties, and they also reduce fever. You can also find quinine as a natural remedy or inside of our Parasite and Worms cleanse. Quinine is added to some tonic water products, too.
Quinine and pharmaceutical quinine medicines are all helpful malaria treatments. But over time, scientists have tested quinine-derived medicines— including chloroquine and hydroxychloroquine— and found them helpful for many other types of illnesses, too.
However, like pharmaceuticals, they brought worrisome side effects with them, too. Today, they’re still used to treat autoimmune disease (like rheumatoid arthritis), lupus, certain types of cancer, and more, despite the hazards they pose.
The buzz around hydroxychloroquine and COVID-19
So, what makes scientists and doctors so confident in an antimalarial medicine for COVID-19? For starters: COVID-19 is the name of the disease caused by a highly contagious coronavirus. However, COVID-19 isn’t the only illness caused by a coronavirus. It also isn’t the only disease hydroxychloroquine has been used to treat, either. SARS (severe acute respiratory syndrome) is also caused by a coronavirus. So is the common cold, influenza, and many other diseases, according to the National Foundation for Infectious Diseases. (Which may come as a surprise!)
Hydroxychloroquine is effective for some of these, as well. It’s also being researched as a potentially very effective treatment for the rest as well. Since it has a history of treating coronavirus already, scientists have been quick to study hydroxychloroquine as a top drug candidate for COVID-19. Even now, studies this year (2020) are showing it has promised: one study shows it can control extreme fever, while another shows it can treat coronavirus-caused pneumonia.
It could also both prevent the coronavirus disease and help treat people with symptoms of it, too. Still, its side effects and health dangers are noteworthy and have been highlighted in some research articles as well.
Hydroxychloroquine is antiparasitic. Is coronavirus a parasite?
So, how do you explain its benefits against coronavirus specifically (especially since it’s an antimalarial, and malaria is caused by a parasite)? Hydroxychloroquine is both an anti-parasitic and an anti-viral. This explains why it’s used to treat so many viral illnesses, not just malaria parasites.
Ask a doctor how the drug works, and they’ll tell you that it uses very similar tactics to fight both parasites and viruses alike. When fighting the malaria parasite (Plasmodium spp.), it breaks down membranes in the parasite’s cellular structure and eventually kills it. This stops it from spreading or having further effects.
With viruses, the quinine-derivative does a similar thing: it interferes with a virus in ways that make it hard to replicate and spread. It also hampers its ability to latch onto tissues and spread that way, too, according to Live Science.
To sum up: hydroxychloroquine (and other quinine medicines, too) are downright virus killers! Not only that: its anti-inflammatory effects are key to fighting the body’s overactive cytokine response (a.k.a. fever), an overpowering (and dangerous) symptom of some diseases, including malaria and COVID-19.
But unfortunately, this pharmaceutical can bring harm to the body, too, in the way that it works.
