The product information for macrolide antibiotics contained warnings about the potential for cardiovascular adverse events, including QT prolongation, and the potential for interaction with other medicines known to cause QT prolongation. The World Health Organization (WHO) and the U.S. National Institutes of Health (NIH) have also stopped studies evaluating hydroxychloroquine for the treatment of COVID-19 due to a lack of benefit.

A crossover comparison of metoprolol and hydrochlorothiazide has been performed in 20 patients with mild hypertension. However, the general consistency of the results relating to small increases in cardiac risk to hydroxychloroquine in combination with azithromycin across the different cardiac-related outcomes and databases adds weight to the findings. Independent public reference data from 377 confirmed COVID-19 patients in the same community were used as untreated controls. In an observational study on 22 people with high blood pressure taking hydrochlorothiazide long-term (2 - 12 years), 36% developed high blood calcium levels [ 36, 37, 38 ]. Hydroxychloroquine has not been proven helpful for COVID-19 and may lead to stomach or heart side effects, as well as serious drug interactions. nausea and vomiting.
