It is usually associated with QT prolongation. This wording is considered to remain an adequate description of the potential cardiac adverse effects, in view of the available data. Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases . If you have lupus, it may also improve the rash. A 95% CI suggests that there is a 95% chance that the real difference between 2 groups is within this interval. The Medicines and Healthcare products Regulatory Agency (MHRA) and the Pharmacovigilance Expert Advisory Group (PEAG) of the Commission on Human Medicines (CHM) have reviewed the available safety data for the use of hydroxychloroquine (a medicine used to treat conditions such as rheumatoid arthritis) at the same time as an antibiotic called azithromycin from the group known as macrolides. The PRR for azithromycin and TdP/QT prolongation was 4.10 (95% CI 3.80 to 4.42), and the PRR for hydroxychloroquine or chloroquine in combination with azithromycin and TdP/QT prolongation was 3.77 (95% CI 1.80 to 7.87). vomiting.

In the cohort study analysis comparing hydroxychloroquine in combination with azithromycin to hydroxychloroquine in combination with amoxicillin, 3 severe adverse event outcomes appeared increased with the short term use of hydroxychloroquine in combination with azithromycin in meta-analysis: chest pain or angina (HR 1.15 (95% CI 1.05 to 1.26), heart failure (HR 1.22 (95% CI 1.02 to 1.45)), and cardiovascular mortality (HR 2.19 (95% CI 1.22 to 3.94)). Similar results were obtained in the SCCS analyses, which looked at the effect of hydroxychloroquine use (on-treatment versus off-treatment) on all outcomes (except mortality outcomes), regardless of indication. Based on the strength of the evidence for harm when these medicines are used in combination, the outcome of the review was that product information should be updated to inform healthcare professionals of these risks.
