Azithromycin is used in infections of the respiratory tract; ear, skin and soft tissue infections; infections of the urethra; and sexually transmitted infections including chlamydia and gonorrhoea. In the UK, hydroxychloroquine is indicated in adults for treatment of rheumatoid arthritis, discoid or systemic lupus erythematosus, and dermatological conditions caused or aggravated by sunlight, and in children for juvenile idiopathic arthritis (in combination with other therapies), and discoid or systemic lupus erythematosus.

Patients who also have other health issues such as heart and kidney disease are likely to be at increased risk of these heart problems when receiving these medicines. The data from spontaneous ADR reports were limited and did not provide any substantial evidence to inform an assessment of the potential for interactions between hydroxychloroquine or chloroquine and macrolides when used in their authorised indications. Uses. For the secondary SCCS, many time-varying covariates including age, season, and other drug exposures were included in conditional Poisson regression models. with a half-life of 537 hours (22.4 days).

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). No difference was found in the primary endpoint, which was the incidence of death at 28 days (26.8% hydroxychloroquine vs. 25% usual care, 95% CI 0.96-1.23; p=0.18).
