Hydroxychloroquine is used to treat autoimmune diseases, such as systemic lupus erythematosus and rheumatoid arthritis, in addition to malaria. Both chloroquine and hydroxychloroquine increase the endosomal pH, which inhibits fusion between SARS-CoV-2 and the host cell membrane. 1 Chloroquine inhibits glycosylation of the cellular ...

Recommendation
Rationale
- Hospitalized Patients
In a large randomized controlled platform trial of hospitalized patients in the United Kingdom (RECOVERY), hydroxychloroquine did not decrease 28-day mortality when compared to the usual standard of care. Patients who were randomized to receive hydroxychloroquine had a longer me… - Nonhospitalized Patients
Several randomized trials have not shown a clinical benefit for hydroxychloroquine in nonhospitalized patients with early, asymptomatic, or mild COVID-19.16,17 In an open-label trial, Mitja et al. randomized 307 nonhospitalized people who were recently confirmed to have COVID …
Adverse Effects
- Chloroquine and hydroxychloroquine have similar toxicity profiles, although hydroxychloroquine is better tolerated and has a lower incidence of toxicity than chloroquine. Cardiac adverse events that have been reported in people who received hydroxychloroquine include QTc prolongation, Torsades de Pointes, ventricular arrythmia, and cardiac deaths.21 The use of azithromycin has a…
Drug-Drug Interactions
- Chloroquine and hydroxychloroquine are moderate inhibitors of cytochrome P450 2D6, and these drugs are also P-glycoprotein inhibitors. Chloroquine and hydroxychloroquine may decrease the antiviral activity of remdesivir; coadministration of these drugs is not recommended.25
Drug Availability
- Hydroxychloroquine, chloroquine, and azithromycin are not approvedby the Food and Drug Administration (FDA) for the treatment of COVID-19. Furthermore, the FDA Emergency Use Authorization for hydroxychloroquine and chloroquine was revoked in June 2020.
