Where people who receive a medicine are also more likely to have a particular risk factor then they may be more likely to develop a medical condition because of this risk factor and not because of the medicine. Furthermore, a significant risk was identified for users of hydroxychloroquine and azithromycin combined, with a 15% to 20% relative increase in the risk of angina or chest pain and heart failure and an approximately 2-fold relative increase in the risk of cardiovascular mortality in the 30 day short-term analysis.

Based on this data, investigators stopped enrollment in the RECOVERY hydroxychloroquine arm on June 5th, 2020. The rate of azithromycin absorption after administration of chloroquine was similar to that of azithromycin administered alone, and the authors reported that chloroquine had no clinically relevant effect on the pharmacokinetics of azithromycin. However, there is a possibility that for community-acquired pneumonia or other infections there may be patients for whom the antibiotics recommended by clinical guidelines are not effective or not tolerated and where azithromycin would represent an authorised and potentially effective treatment option. FDA cautions against use of hydroxychloroquine or chloroquine for COVID-19 outside of the hospital setting or a clinical trial due to risk of heart rhythm problems. Confidence intervals (CI) are used to assess the true difference in risk between 2 groups, and usually accompany ratio values such as odds ratios, hazard ratios and observed versus expected ratios. Patients started treatment within 4 days after exposure, defined as being in close contact with a COVID-19 patient for more than 10 minutes without protection. The RECOVERY Collaborative Group. A type of study where health outcomes are compared for each study participant in the time before they are exposed to some event (such as taking a medicine) and in the time after they are exposed to it. Mixed studies have reported both a positive and negative effect, and data may not be robust or reliable: it can include data from study reviews, nonrandomized groups, retrospective research, observational data or from a statistically small sample size of patients. This remains the case at time of publication in February 2022, and no new studies have been identified that alter the conclusions of this MHRA review. The study by Lane and colleagues showed that people who take hydroxychloroquine at the same time as azithromycin are more likely to get side effects affecting the heart within a short period of time (up to 30 days) of starting to take these medicines together, compared with people who take hydroxychloroquine at the same time as amoxicillin. diarrhea.
