The greatest amount of evidence on the safety of this combination in a post-marketing setting comes from the large study by Lane and colleagues. There may be some situations in which the benefit of being able to treat a serious infection with azithromycin in a patient who is also taking hydroxychloroquine is greater than the risks to that patient of side effects affecting the heart. These risks may increase when these medicines are combined with other medicines known to prolong the QT interval, including the antibiotic azithromycin, which is also being used in some COVID-19 patients without FDA approval for this condition.

The FDA is aware of reports of serious heart rhythm problems in patients with COVID-19 treated with hydroxychloroquine or chloroquine, often in combination with azithromycin and other QT prolonging medicines. No amendments to the hydroxychloroquine product information regarding cardiovascular risk when it is not used in combination with macrolides are considered necessary on the basis of the data from the study by Lane and colleagues and this review. Pharmacokinetics describes how the human body affects a medicine, such as , how the medicine is absorbed, chemical changes the medicine undergoes, how the medicine moves through the body and is eventually removed from the body. The MHRA received independent advice on this review from the Pharmacovigilance Expert Advisory Group, an independent group of experts that advises the Commission on Human Medicines on the safety of medicines. Sarayani and colleagues examined data from the FDAs Adverse Event Reporting System (FAERS) to determine whether there was a disproportionality of reporting of events of death and Torsades de Pointes (TdP) or QT prolongation for azithromycin, hydroxychloroquine, or chloroquine alone, as well as for hydroxychloroquine or chloroquine in combination with azithromycin, or for hydroxychloroquine or chloroquine in combination with amoxicillin (Sarayani and colleagues, 2020). Warnings have also been added to the product information for azithromycin and two other macrolide antibiotics called clarithromycin and erythromycin.

Hydroxychloroquine has not been associated with improved survival among hospitalized COVID-19 patients in the majority of observational studies and similarly was not identified as an effective prophylaxis following exposure in a prospective randomized trial. It is therefore anticipated that the most likely situation where these medicines might be used concomitantly would be where azithromycin is indicated for an infection occurring in a patient on existing long-term hydroxychloroquine treatment. they could play a critical role in early diagnosis, treatment and management of disease progression and virus spread.

The same risks do not apply to products intended for application to the skin or for use as eye drops. The paper from Lane and colleagues presents data on the largest available epidemiological study of the safety of hydroxychloroquine, with data primarily from the authorised indication of rheumatoid arthritis. One common situation where someone is taking more than one blood pressure . However, the FDA withdrew that authorization when data analysis showed that the drugs are not effective for treating COVID-19. Longer term treatment with hydroxychloroquine, as used for rheumatoid arthritis, was associated with a 65% relative increase in cardiovascular mortality. Hydroxychloroquine, an FDA-approved prescription drug used for malaria, rheumatoid arthritis and lupus erythematosus, has been suggested as a possible treatment or preventive for COVID-19 based on demonstrated antiviral or immune system activity. Hydroxychloroquine and chloroquine can cause abnormal heart rhythms such as QT interval prolongation and a dangerously rapid heart rate called ventricular tachycardia. Hydroxychloroquine has been reported to have in vitro activity against SARS-CoV-2 7,8 through several mechanisms, including impairment of the terminal glycosylation of the angiotensin-converting enzyme receptor 2 (ACE2), the link between the envelope spike glycoprotein and also inhibiting the function of the endolysosome. It is expected that healthcare professionals will take into account these risks when considering if there are any circumstances where the benefit of such concomitant use might outweigh the risks. . The disease or condition, or manifestation or symptoms thereof, for which the drug is approved. As with all observational studies that make secondary use of data, there may be misclassification in terms of both exposure and outcome. Mild side effects may go away within a few days or a couple of . For the new user cohort study, key predictors of exposure classification were selected for use in a propensity score, which was then used to stratify analyses to adjust for imbalance between exposure cohorts. Hydrochlorothiazide 25 mg package 360 pills In various studies, the drug has demonstrated antiviral activity, an ability to modify the activity of the immune system, and has an established safety profile at appropriate doses, leading to the hypothesis that it may also be useful in the treatment of COVID-19. This risk might be anticipated based on the known cardiac toxicities of both products, possibly due to combined effects on QT interval, or by combined cardiotoxic effects more generally. This remains the case at time of publication in February 2022, and no newer studies have been identified that alter the conclusions of this MHRA review. Mortality, by treatment, was 20.1% for hydroxychloroquine + azithromycin, 13.5% for hydroxychloroquine alone, 22.4% for azithromycin alone, and 26.4% for neither drug (p<0.001).
