Self-treatment and adverse reactions with herbal products for treating symptoms associated with anxiety and depression in adults from the central-western region of Mexico during the Covid-19 pandemic

Abstract

Ethnopharmacological relevanceThere are plant species used in the Mexican traditional medicine for the empirical treatment of anxiety and depression. Aim of the studyThis work assessed the prevalence of self-medication with medicinal plants and the prevalence of the concomitant use of prescribed psychiatric drugs and medicinal plants for treating symptoms associated with anxiety and depression during the Covid-19 lockdown in Mexico. Materials and methodsThe suspected adverse reactions associated with drug-herb interactions were assessed. The factors associated with self-medication, the concomitant use of herb-drug combinations, and the presence of adverse reactions due their combined use is also reported. The study was descriptive and cross-sectional using an online questionnaire conducted among population with symptoms associated with anxiety and depression (n = 2100) from seven states of central-western Mexico. ResultsThe prevalence of the use of herbs (61.9%) and the concomitant use of drug-herb combinations (25.3%) were associated with being diagnosed with mental illness [OR:2.195 (1.655–2.912)] and the use of psychiatric medications [OR:307.994 (178.609–531.107)], respectively. The presence of adverse reactions (n = 104) by the concomitant use of drug-herb combinations was associated with being unemployed [p = 0.004, OR: 3.017 (1.404–6.486)]. ConclusionHealth professionals should be aware if their patients concomitantly use medicinal plants and psychiatric drugs. Public health campaigns should promote the possible adverse reactions that might produce the concomitant use of drug-herb combinations for mental illnesses.
