Drug safety of frequently used drugs and substances for self-medication in COVID-19

Scoping review on lessons learnt on the promotion and use of drugs and traditional medicine in Africa during COVID-19

ABSTRACTScientific evidence on the safety and efficacy of pharmaceutical drugs, substances and herbal medicines is important in medical advertising and promotion. Following guidelines for conducting a scoping review, we systematically searched PubMed, SCOPUS and Web of Science to identify in peer reviewed articles medications that were promoted and used widely in Africa during the COVID-19 pandemic. We also searched for information about how safety concerns about untested/or not properly tested drugs were communicated to the public during the pandemic. Of the 2043 articles identified, 41 papers were eligible for inclusion. Most studies were clinical trials (n = 11), systematic reviews (n = 9), quantitative studies (n = 9) the rest were qualitative studies, reviews and reports. We found that following global trends, several drugs, traditional and herbal treatments were used and repurposed for the treatment of respiratory symptoms of COVID-19 in Africa. The results highlighted the value of some herbal medicines for treatment during the COVID-19 pandemic, as well as the risks posed by the unregulated sharing of advice and recommendations on treatments in Africa, and globally.

Self-Medication during and after Cancer: A French Nation-Wide Cross-Sectional Study

(1) Background: Little data are available in Western countries regarding self-medication practices in the context of cancer. The aim of this study was to describe the prevalence of self-medication practices during (cancer patients) and after cancer (cancer survivors). (2) Methods: This multicenter, cross-sectional, and online study was designed to assess self-medication prevalence. Other objectives were explored, notably the medication types, the perceived risks, and the relation with symptoms and quality of life. (3) Results: Among the 518 patients analyzed, 56.4% declared they practiced self-medication. Dietary supplements and pain medications were used by more than half of the patients. Self-medication was practiced in order to manage the adverse effects of anticancer therapies (63.8%), for which pain was the leading indication (39%), and to improve the efficacy of anticancer therapies (43.8%, cancer patients). Patients believed that self-medication could not lead to drug interactions with anticancer therapies (84.9%, cancer patients), or to adverse effects (84.6%, cancer patients and survivors). Self-medication practices were associated with altered social functioning, pain, insomnia, and financial difficulties. (4) Conclusions: Self-medication was performed by more than half of the responders (ongoing or past cancer) and could be a marker of the undermanagement of cancer and treatment-related adverse effects.

A report on SARS-CoV-2 first wave in Ecuador: drug consumption dynamics

Introduction: The first COVID-19 wave in Ecuador started in March 2020 and extended until November. Several types of drugs have been proposed as a potential treatment during this period, and some affected people have self-medicated. Method: A retrospective study was conducted with 10,175 individuals who underwent RT-PCR tests for SARS-CoV-2 from July to November 2020. We compared the number of positive and negative cases in Ecuador with symptoms and drug consumption. The Chi-square test of independence compared clinical and demographic data and PCR test results. Odds ratios analyzed drug consumption dynamics. Results: Of 10,175 cases, 570 were positive for COVID-19, while 9,605 were negative. In positive cases, there was no association between the RT-PCR result and sex, age, or comorbidities. When considering demographic data, Cotopaxi and Napo had the highest rates of positive cases (25.7% and 18.8%, respectively). Manabí, Santa Elena, and Guayas regions had fewer than 10% positive cases. The Drug consumption dynamic analysis showed that negative COVID-19 cases presented higher drug consumption than positive cases. In both groups, the most consumed medication was acetaminophen. Acetaminophen and Antihistamines had higher odds of consumption in positive PCR cases than in negative. Symptoms like fever and cough were more related to positive RT-PCR results. Conclusion: The first COVID-19 wave in Ecuador has affected the provinces differently. At a national level, the consumption of drugs has been highly associated with self-medication.
