The aim of the study is to identify the current practices of self-medication in Bulgaria, estimate the extent patients are influenced by information about the safety of OTC products and pharmacists’ role and behavior in the process. An anonymous, questionnaire-based, descriptive study was carried out among 280 pharmacists.

The majority of the patients (92.6%) ask for pharmacists’ advice before buying OTC products. Most often patients need OTC drugs for mild conditions (80.7%), to save time (63.9%), and because they are unable to consult a physician (61.9%). The medium duration of consultation for an OTC product is between 5 and 10 minutes. The main barriers hindering the process are unwillingness from the patient (72.5%), lack of time (27.5%), and lack of confidentiality (26.6%). OTC medicines are considered safer than prescription-only medicines by pharmacists.

Pharmacists could substantially contribute to rational self-medication and alleviate the burden on healthcare systems.

self-medication, pharmaceutical counseling, over-the-counter medicines

Self-medication is defined as the selection and use of medicines by individuals to treat self-recognized or self-diagnosed conditions or symptoms (WHO 2000). The role of self-medication in modern healthcare systems is increasing as healthcare policies worldwide promote citizens’ empowerment and responsibility concerning their health and well-being (Bonsignore et al. 2014). It is a common practice among many people around the world (Irfadh et al. 2013).

Previous local studies indicate that the consumption of OTC products is increasing and the main stimulus for patients is convenience (Tsvetkova et al. 2014; Belcheva et al. 2016; Belcheva et al. 2017). 9.7 billion packs of non-prescription medicines were bought by Europeans in 2019 (AESGP 2019). In total, more than 200 active pharmaceutical ingredients (by INN) in more than 4000 different medicinal products are available in Europe without prescription. These include medicines for common ailments such as allergies, stomach upsets, cuts, bites & rashes, coughs & cold, pain. The general benefits of self-medication include facilitating better use of clinical skills, increasing access to medication, and contributing to reducing prescribed drug costs associated with publicly funded health programs (Hughes et al. 2001; Noone and Blanchette 2018). However, self-medication is associated with risks such as misdiagnosis, use of excessive drug dosage, prolonged duration of use, drug interactions, and polypharmacy (Hughes et al. 2001). The inappropriate use of products for self-medication results also in adverse drug reactions, disease masking, increased morbidity, antibiotic resistance, and wastage of healthcare resources (Awad et al. 2006; James et al. 2006; Sahebi and Vahidi 2009; Suleman et al. 2009; Alam et al. 2015; Dyar et al. 2019).

In Bulgaria over-the-counter (OTC) medicines are dispensed without prescription and are sold exclusively in community pharmacies (ZLPHM 2019). Pharmacists are considered the most accessible healthcare professionals in Bulgaria. They can recommend OTC medicines but also provide overall pharmaceutical care (ZLPHM 2019; Georgiev 2018). In 1992, FIP developed standards for pharmacy services entitled “Good Pharmacy Practice (GPP) in community and hospital pharmacy settings”. One of the four pharmacy elements of good pharmacy practice covers activities associated with self-care, including advice for managing ailments that can be self-treated successfully (WHO 2000).

However numerous studies suggest that the quality of primary health care in self-medication would improve if pharmacists’ involvement were more intense (Krishnan and Schaefer 2000; You et al. 2011). The role of the pharmacist in promoting rationale self-medication is crucial in improving patient outcomes. To elevate the quality of counseling it is important to identify everyday practice and unmet needs.

The aim of this study is to identify the current practices of self-medication in Bulgaria, estimate the extent patients are influenced by information about the safety of OTC products, and pharmacists’ role and behavior in this process.

An anonymous, questionnaire-based, descriptive study was performed in 2019. The questionnaire was developed based on a pilot study conducted in Bulgaria in 2018 (Lebanova et al. 2018). It consisted of a total of 16 questions divided into 2 sections: (1) patients’ habits and preferences in over-the-counter medications and (2) role and behavior of the pharmacist in patient self-medication counseling. All questions were with multiple-choice answers and provided an opportunity for an open-ended response.

Data were analyzed using SPSS. Descriptive statistics were reported by mean or percentage, as appropriate. The category variables were presented as absolute and relative frequencies, and the quantitative ones – as median and interquartile range, as they are not normally distributed. The Kolmogorov-Smirnov method was used to estimate the shape of the distribution. The relationships between categorical variables were evaluated by chi-square analysis (Fisher’s exact test in tables 2 × 2). The Spearman correlation coefficient was used to estimate the relationship between quantitative variables. Statistical analyzes were applied at a significance level of 0.05.

General practitioners (GPs) are the primary source for treating minor ailments (EPPOSI 2013). The majority of these conditions could be managed successfully in a pharmacy setting. Improving self-care and promoting rational self-medication can help to ease the burden on the heаlthcare systems especially in the context of the Covid-19 pandemic. Minor ailments such as pain, temperature, cough, diarrhea/constipation, allergy are in most cases widespread seasonal conditions. One of the first steps in ascertaining the role of the pharmacist as an accessible healthcare resource capable of meeting the challenges of the evolving consumer needs is the recognition of pharmacists’ ability of counseling and providing pharmaceutical care in self-medication. The quality of counseling depends on many factors but according to our results, the main barrier is the patient’s unwillingness. This is indicative that there is still an unmet need in recognising the pharmacists’ role as healthcare consultants and sources of reliable health information.

Another barrier to adequate counseling is patients’ perception of the pharmacist’s role. The community-based practice has evolved from compounding and dispensing to pharmaceutical care and counseling (Goode et al. 2019). The results of our study show that Bulgarian consumers haven’t embraced the change as the primary sources of information for the patients are still advertisements and the internet. The quality of medicines information on the world-wide-web is known to be mostly mediocre and could lead to drug-related problems (Lebanova et al. 2014). To facilitate counseling and promote safe self-medication pharmacists should lead the process. As the control of a disease is a bilateral process between the patient and the physician, self-care is a bilateral process between the patient and the pharmacist (Stoev et al. 2015).

Pharmacists’ attitude toward OTC medicines is crucial in shaping their behavior in self-medication counseling. Our study found that Bulgarian pharmacists believe that OTC products are safe. However, OTCs are believed also to be of a higher potential for abuse, drug interactions, and ADRs. It is not accidental that the majority of pharmacists emphasize on safety when counseling along with efficacy. This phenomenon is most visible among those with the longest work experience. Promoting rational drug and adherence use is of utmost importance in reducing the risk of self-medication (You et al. 2011). One of the most vulnerable populations are patients with chronic diseases who are prone to a higher risk of drug interactions between prescription drugs for chronic diseases and OTC products (Kaufman et al. 2002).

The results of our study suggest that Bulgarian pharmacists can undertake a more active role in patients’ self-care. Published data shows that community pharmacist-provided self-care programs had demonstrated a positive impact on chronic diseases (Barbanel 2003; Doucette et al. 2009).

Self-care and self-medication are an important aspect of the evolving healthcare systems. Pharmacists play a crucial role in empowering patients to manage minor ailments. The results of our study show that pharmacists are willing to provide counseling and participate in the process. The behavior of the pharmacists is shaped mainly by their belief that OTC medicines are effective but with higher potential for abuse, drug interactions, and ADRs. The main barrier to this process is patients’ perception of the role of the pharmacist as a health consultant.
