A look at COVID-19 remedies: Which ones work finest?


Hydroxychloroquine, remdesivir, ivermectin and monoclonal antibodies are among the most-talked about medicine in terms of COVID-19. CBS Dallas spoke with Dr. Robert Gottlieb, of the Baylor Scott & White Research Institute, to be taught extra about every.

“There are many therapies that work on paper, or even in the laboratory, that don’t work when you bring them to a human” Dr. Gottlieb informed us. “We have to remember that we’re not trying to treat a virus in a test tube, we’re trying to treat a virus in a human being.”

At the start of the pandemic, docs tried all the things they might to save lots of lives, together with some remedies that at the moment are confirmed not as efficient as as soon as thought. With extra analysis, docs now higher perceive which ones truly work, and have the science and information to again it up.


“We’ve clearly studied hydroxychloroquine,” stated Gottlieb. “We’ve shown that … it just doesn’t help for the virus.”

Hydroxychloroquine is an antimalarial drug additionally used to deal with circumstances resembling rheumatoid arthritis and lupus. Early research confirmed promise in a laboratory setting, and docs thought the drug might assist preserve folks’s immune techniques from overreacting, however Gottlieb stated peer reviewed research discovered that it doesn’t profit sufferers hospitalized with COVID-19.

“We can draw a very complex pathway of why it should work, but we can’t will it into existence as an effective therapy. The data is the data.”


A second therapy exhibiting promise, at least for extreme instances of COVID, is an antiviral referred to as remdesivir.

“Remdesivir decreases duration of hospitalization, regardless of oxygen support level required in the hospital. It actually saves lives,” stated Gottlieb.

The drug acquired full FDA approval final October to be used in grownup and pediatric COVID sufferers 12 and older requiring hospitalization. It’s nonetheless being studied for outpatient use.


Another potential therapy that is receiving a variety of consideration is ivermectin. It is FDA permitted to deal with sure parasitic worms, head lice and pores and skin circumstances like Rosacea. It additionally has proven some antiviral properties, however the jury remains to be out on whether or not it may be used as an efficient therapy for COVID-19. Clinical trials are underway, however Gottlieb stated it is simply too early to know if it is useful.

“We haven’t completely disproved it, but we have no evidence at the moment of efficacy,” Gottlieb stated. “So right now, we don’t know that answer. There’s no recommendation for it. I personally do not prescribe it.”

Human-grade ivermectin requires a prescription, however it’s also a drug that is used for animals. Because of its reputation on blogs and social media, there have been reviews of individuals raiding feed shops to purchase the animal-grade model. Gottlieb stated that’s harmful and will preserve somebody from getting a therapy that’s confirmed to work.

“If someone thinks that they’re being protected by ivermectin and they’re not, you’re really just prescribing them a version of a placebo and losing the opportunity to actually get treated with an effective therapy,” Gottlieb stated. “From that standpoint, it really is harmful, because it gives the illusion of protection.”

Monoclonal antibodies

The most promising therapy at the second in an outpatient setting is monoclonal antibody remedy.

“If you have one or more mild symptoms, it doesn’t matter how mild they are, those are the patients we studied, and we showed that we could prevent 70 to 87% of those patients from being hospitalized,” stated Gottlieb. “We could actually save lives, if used early.”

Gottlieb stated there’s three totally different producers, and there isn’t any comparative efficacy information. He stated the one which’s on the shelf in your healthcare system is the suitable one. Various facilities have opened throughout Texas to supply the remedy freed from cost. The physician stated outdoors of medical trials, it is necessary to stay with what we all know will work.

“Even as I conducted the research, I was really convinced that therapy X or therapy Y would really work,” Gottlieb defined. “When we’ve actually wrapped up the study and actually determine who’s who, I’ve been very humbled by that answer.”

Cortico steroids

Another sort of medicine Gottlieb stated is proving useful, and can be low-cost and available: corticosteroids. They’ve been proven to be helpful for hospitalized sufferers needing oxygen, however can truly be dangerous for many who should not in that scenario.

Gottlieb stated the most effective protection is to get the vaccine. He additionally stated there’s nothing unsuitable with taking nutritional vitamins D and C or a multivitamin. He stated whereas they could probably not affect the virus, there’s actually no draw back they usually could make you are feeling extra constructive. That mentality in itself is highly effective.
