Information You Need: Is Hydroxychloroquine effective against COVID-19?


Scientific studies have found that there are not any notable preventative or treatment benefits for hydroxychloroquine use against the SARS-CoV-2 virus.

Earlier in the pandemic, hydroxychloroquine was mentioned heavily in the news as a potential treatment or preventative measure against COVID-19. However, at that time, little was known about the drug’s effects on the virus. Since then, much more research has been done to explore whether or not this drug is a beneficial preventative or treatment measure. Many scientific studies, including randomized control trials, have found that hydroxychloroquine provided no to minimal benefits in preventing the virus or among hospitalized COVID-19 patients and could lead to lethal heart rhythm abnormalities. Other treatments that have been shown to be more effective include monoclonal antibody therapy, remdesivir and corticosteroids. There is some limited evidence that if you are vitamin D deficient, supplementation can boost your immune system. Low doses, under 1000 IU are considered safe, but high doses of vitamin D are not recommended as over 4000 IU per day can be harmful. Vitamin C has also gotten attention but at high doses, it can cause nausea, cramps, and an increased risk of kidney stones. In general, supplement only if you are deficient and cannot obtain daily requirements through your diet.
