ABSTRACT:
Background: The incidence of usage of over-the-counter (OTC) drugs is drastically increasing day by day. Over-the-counter drugs are medicines that are safe and effective for use by the general public without a prescription. In India till date, there are no specific unifying regulations related to use and sale of OTC products and this impacts both the accessibility to better health care and patients' safety due to inappropriate use. The aim behind this study is to assess the perception of OTC practices among general public. Objective: This study aimed to investigate the general public’s knowledge, attitudes, and behavior about the safe use of OTC medicine. Methods: A cross-sectional study was conducted using a self-administered online questionnaire. The questionnaire comprised five sections: demographic information, knowledge, attitudes, practice, and stocking of OTC medicines. Data were coded and entered in EXCEL and SPSS databases for statistical analysis. Results: A total of 347 participants were enrolled in the study. A total of 335 students returned a completed questionnaire. The students had a mean knowledge score of 7.6 out of 12, with more than 22.5% having good knowledge (> 9), 66% having moderate knowledge (5-8), and only a small percentage (11.5%) with poor knowledge. Almost all students (96.3%) had a positive attitude toward OTC medicine use. Few of the students practiced improper habits in terms of OTC medicine use, such as not reading the instructions or taking more than the recommended dose. Awareness of proper OTC medicine use among students in institutions of higher learning is necessary to prevent the rise of inappropriate user practices. Conclusion: Self-medication is widely practiced among the majority (55.3%) of the participants. Hence awareness of proper OTC medicine use in the community is necessary to prevent the rise of inappropriate user practice.
KEYWORDS: Over the counter (OTC), Cross-sectional survey, Knowledge, Attitude, Behavior, Practice.
INTRODUCTION:
A paradigm shift has been observed in self-medication practice with OTC medicines in recent times and has become a widespread practice worldwide1. The self-medicating practice of using over-the-counter (OTC) medications is more common than prescription drug use and it is a growing public health concern worldwide2. Over-the-counter (OTC) medicines are medicines that may be sold directly to a consumer without a prescription from pharmacy personnel, as compared to prescription drugs, which are dispensed only to consumers possessing a valid prescription3. The World Health Organization defines self-medication as the independent selection and use of medication by an individual to treat illnesses and symptoms of which he or she is aware, or the self-administration of drugs prescribed by a physician to treat a chronic or re-occurring condition4. Though it was previously considered unnecessary, responsible self-medication is an essential aspect of self-care5. Self-care is common in an environment where effective medicines are readily available, such as over-the-counter (OTC) medicines. Self-care has the potential benefits of effective treatment, reducing medical pressure by reducing the number of doctor visits, reducing medical costs, and improving the independence of patients as they manage their health6,7.
Worldwide, improper nonprescription medication use is often associated with limited information and low knowledge of medication use8. Delays in treatment occur because of incorrect self-diagnosis9. Review studies have found that the majority of preventable adverse drug reactions are related to excessive dosage10, whereas several negative consequences include adverse drug events and drug interactions associated with polypharmacy11. There is also the potential for misuse and abuse of such products12.
Regarding the knowledge, attitude, and practice of healthcare professional students regarding the use of self-medication and related adverse drug reactions, substantial difference has been reported in various studies13–16. Knowledge of OTC medicines is crucial as they could help avoid health hazards and increase the effectiveness of the medications. Studies conducted in Japan showed that more than 30% of OTC allergic rhinitis drug users were found to be using the drugs indiscriminately, self-adjusting the dose, using expired drugs, or using the drug beyond the upper limit17. In a study conducted by the USA, 10% of all birth abnormalities are associated with OTC medicine use during pregnancy18. The National Survey on Drug Use and Health (NSDUH) 2020 data, percentages of people in each age group misused nonprescription cough and cold medicines to get high in the past year (0.9 percent of adolescents aged 12 to 17, 1.2 percent of young adults aged 18 to 25, and 0.8 percent of adults aged 26 or older)19.
South Asian countries, in particular, demonstrate higher rates of self-medication20. For instance, Nepal has a rate of 59%, Pakistan has 51%, and Bangladesh shows rates of 81.3% among the younger population and 78.5% among the elderly21. In Bangladesh, antimicrobial resistance is a significant issue, primarily attributed to unethical drug sales practices. A recent petition filed in the High Court of Bangladesh aimed to address this problem by seeking legal action against the immoral selling of drugs. It was highlighted that as much as 80% of deaths caused by infections were linked to antimicrobial resistance22,23.
In India, there are no regulations regarding Non- prescription (OTC) drugs. Thus, to date, there are no specific unifying regulations related to the use and sale of OTC products and this impacts both the accessibility to better health care and patients' safety due to inappropriate use. India, Drugs and Cosmetics Act, 1940(amended up to 2016) and its subordinate legislation, the Drugs and Cosmetics Rules, 1945 (amended up to 2020) regulate the import, manufacture, distribution, and sale of drugs and cosmetics. “Prescription-only drugs” have been placed in Schedule H, H1, G, and X of the Drugs and Cosmetic Act (1940) but non-prescription (OTC) drugs are not included as a separate category. Draft regulations to amend Schedule K – containing household remedies were issued in May 202224. OTC regulations in India are still in the process of being framed.
To prevent irrational drug use, it is necessary to first assess the prevalence of self-medication with OTC among individuals and understand the factors contributing to the same. This study was carried out to assess the knowledge and understanding regarding Non- non-prescription (OTC) drug use and associated factors among the general public.
An online cross-sectional survey was conducted by circulating a questionnaire. The questionnaire was created using Google Forms in English language, and the link was distributed via various messaging platforms. It was open for responses for a total of 16 days, from April 19 to May 4, 2024, after which the responses were closed and no longer accepted. The survey involved students and faculty from 29 different departments of Pt. Ravishankar Shukla University, Raipur, Chhattisgarh. Respondents were of different age groups, all 18 years old or above.
A self-administered, structured, and pre-tested questionnaire was used. The questionnaire was adapted from previously conducted similar studies and modified to fit the current context3,25–27. The internal consistency of the questionnaire was determined using Cronbach’s alpha. The questionnaire consisted of 34 questions broadly divided into five sections:
1. Socio-demographic data (4 questions)
2. Knowledge (12 questions)
3. Attitude (6 questions)
4. Practice (10 questions)
5. Stocking (6 questions)
For the knowledge section, correct responses were scored as one mark, while incorrect and unsure responses were scored as zero. The total knowledge scores ranged from zero to twelve, which were then categorized as: “Good” (≥nine correct answers), “Moderate” (five-eight correct answers), and “Poor” (<five correct answers). The attitude section was measured using a five-point Likert scale with response options ranging from "strongly disagree" to "strongly agree," each weighing 1-5 respectively. A cumulative attitude score of 15 and above was considered indicative of a positive attitude.(Table 1)

Responses were coded and entered into Excel 2010 and the Statistical Package for Social Sciences (SPSS) version 29.0.2.0(20) for Windows 11, for statistical analysis. The Chi-square test was used to test for significant differences between groups (P < 0.05). In some cases, participants failed to answer every question, resulting in missing data. Missing data were not estimated or included in the analyses.
The questionnaire aimed to reveal self-medication patterns and public views on OTC medicines in terms of safety, potency, and effectiveness, among other factors.
The internal consistency of the final questionnaire was determined using Cronbach’s alpha coefficient. The Cronbach’s alpha values for the knowledge and attitude sections were 0.722 and 0.728, respectively, indicating good reliability.
A total of 347 respondents participated in the survey. Of these, 192 (55.2%) were female. The majority of respondents (278 or 79.9%) were within the age group of 18-24 years, with a mean age of 20.5 years. Regarding qualifications, most participants were graduates (147 or 42.2%) or postgraduates (112 or 32.2%) (Table 2).

The participants had a mean knowledge score of 7.63 out of 12 (SD = 2.57). More than 22.5% of participant’s demonstrated good knowledge (> 9), 66% had moderate knowledge (5-8), and only a small percentage (11.5%) had poor knowledge (see Table 3). Participants' levels of knowledge varied significantly in terms of age (p = 0.004) and place of residence (p = 0.02) (see Table 4). Urban respondents exhibited better knowledge (26.9%) compared to rural respondents (15.6%). Within the entire sample, the 18-24 age group was predominant, with 65.8% of them having moderate knowledge about OTC medication. Compared to male respondents (21.3%), female respondents demonstrated slightly higher levels of good knowledge (23.4%).

The mean attitude score was 21.34 out of 40 (SD = 3.42). Almost all respondents (334 or 96.3%) indicated a positive attitude toward the use of OTC medicine. Among the total study participants, 56 (16.2%) strongly agree and 212 (61.4%) agree that OTC medication is safe when used correctly. About 55 (15.9%) strongly agree and 198 (57.4%) agree that OTC medication is convenient to obtain and use. A total of 158 (45.8%) respondents agreed that OTC medication can be used during pregnancy and while breastfeeding, but with caution, unless there is a warning label to avoid the medication during pregnancy or breastfeeding.
Almost half of the respondents (155 or 45.8%) agreed that they use OTC medications more often now due to increased availability. Additionally, 48 (13.9%) strongly agree and 169 (49%) agree that it is appropriate to treat minor ailments, such as a common cold, with OTC medications. The majority of participants (282 or 81.7%) agreed that they would seek a pharmacist's advice if they are unsure about their minor illness. No significant differences were observed when comparing attitudes among respondents with different demographic characteristics.

More than half of the respondents (192 or 56%) reported that they have practiced self-medication with OTC medicines at least once. Among these, 84 respondents (24.6%) experienced some adverse effects from OTC medication. The majority of respondents (77%) would never take more than the recommended dose; however, 14.1% have consumed OTC medicines in quantities exceeding the recommended dose.
When it comes to sources of information before purchasing suitable OTC medicines, the majority of respondents (229 or 66.6%) reported that their main source is a pharmacist, followed by a doctor (200 or 58.1%), the internet (146 or 42.4%), friends/family (144 or 41.9%), and prior usage (92 or 26.7%). Half of the respondents (177 or 51.8%) consume OTC medications when the symptoms are minor. Additionally, 165 respondents (48.1%) always read the instructions on the medicine's label before use. If the OTC medicine shows a change in shape, color, or odor, 74.6% would immediately discard it.
The most common illnesses for which respondents consume OTC medicines are fever/headache and cough/common cold.

Out of 347 respondents, 64.3% store OTC medication at home. Among these, 155 respondents (69.8%) always check the expiry date of their stockpile, and 148 respondents (43.1%) store their OTC drugs in a cool, dry place or as stated on the label. Despite this, only 103 respondents (46.6%) check their OTC stockpile every month. Alarmingly, half of the respondents (111 or 50.5%) have spoiled their OTC medication at least once due to improper storage. The most favored OTC medicines for stocking at home include pain relievers (70.2%), cold medicine (69.7%), and fever reducers (63.8%). (Table-7).

DISCUSSION:
In recent times, there has been a noticeable shift in self-medication behavior using over-the-counter (OTC) medicines, which has become prevalent on a global scale. In the present study, the prevalence rate of self medication with OTC was 56%. This result was consistent with similar studies, Nepal has a rate of 59%, and Pakistan has 51%21. The low prevalence rate depicts the unawareness and low availability of the population SM with OTC medicines. According to a report, around 67% of the Indian population lives in rural areas. Still, rural markets contribute only 17% of the sales, suggestive of limited access to OTC medicines28.
In the current study, the mean knowledge score was 7.63/12. This finding was less than that of a survey conducted in Sri Lanka, which reported that almost all(93.5%) of the respondents were found to have good knowledge about self-medication and had a positive attitude25. Similar findings were also reported by a study conducted in Thailand 29. The low knowledge score can again be correlated to a lack of awareness about OTC drugs.
In this study, there was a significant difference between knowledge of OTC medicines depending on age (p = 0.004) and place of residence (p =0.02). Respondents of the age group 18-24 years belonging to urban residence have better knowledge of OTC medicine use. This is due to better advertisement and exposure to primary healthcare in urban places30.
Some 84(24.6%) reported that they have experienced adverse effects from OTC medication. Studies have shown that taking more than the recommended dose, failing to check the expiry date, and rarely reading labels are some of the common reasons for adverse reactions31–33.
According to market research data available on Nicholas Hall’s Global CHC Database (DB6 2021), vitamins and supplements (33.8%) hold the most share in the market followed by gastrointestinal 20.9%, then cough, cold and allergy, analgesics and dermatological having 14.6%, 13.7%, and 13.5% respectively34. The majority of respondents (46.2%) in this study choose fever and headache drugs followed by cough and cold 38.9% as common OTC medicine.
The most common source of information on OTC medicine was from pharmacists (66.6%). This study also reported that a lot of participants depend on information from social media (42.2%). This was an unexpectedly high level. In Jordan, students obtained information on OTC medicine from familiarity with the product and advertisement 35. In Nepal, the main sources of information referred to by medical students were pharmacists (60.3%), followed by textbooks (46.3%), and then advertisements (17.5%) 36. Even though the most common source of information is family members, pharmacists play a vital role in safeguarding consumers from potentially inappropriate OTC medicine use37.
Over 69.7% of participants reported always or often reading the instructions on the OTC drug package before they used the product, which is less than that reported previously in China (92%). This decrease could be due to an increase in people’s confidence over time about self-treatment. It could also be due to people’s belief that only safe medicines are permitted to be sold without a prescription and that OTC medicines do not usually have serious side-effects38.
About 2.7% of the students responded that they rarely or never check the expiry date of the OTC medicine before using it. The findings of this study on checking the expiry dates are improved to those from a study in Eritrea where 73.9% of the respondents check the expiry dates8.. However, 31% of respondents in Eritrea never read anything. This is concerning because not reading the label and checking the expiry date may lead to the build-up of those expired medications and many harmful effects39.
In the current study, 28.4% of respondents do not have a habit of checking the storage condition. Besides the dangers of accidental poisoning by children and other related risks associated with improper storage of medications, not having an ideal place to store medications can lead to heat and humidity which can contribute to loss of potency and shortening of the shelf life of the medications40.
Knowledge and practice of self-medication with OTC were associated with age and socioeconomic status in our study. The probable reason for indulging in self-medication for these conditions is the fact that they are considered minor illnesses, self-limiting in nature and doctor’s consultation is not necessary for them.
LIMITATION:
The study investigates and describes a relatively less-known topic. Due to the limited number of cases and the regional recruitment focus, the study cannot claim to be representative. The questionnaire can be further refined to ensure greater appropriateness and relevance to the topic. One main challenge was that constructing the questionnaire was complex, and no comprehensive tools were available to test the knowledge aspect for this study. The intentional misreporting of behaviors by respondents may confound the survey results or conceal inappropriate behavior. Consequently, the responses to the questionnaire may not accurately reflect the actual attitudes or behaviors of the respondents. The practice segment of the questionnaire included recall questions on OTC medicine use, introducing the likelihood of recall bias. Additionally, future studies should incorporate the views and experiences of doctors and pharmacists. To date, only a few papers have been published on this subject.
CONCLUSION:
Respondents exhibit a good level of knowledge and positive attitudes regarding the use of over-the-counter (OTC) drugs. However, there are still some gaps in appropriate practices, particularly in areas such as reading medication labels, checking expiry dates, and proper storage. Despite these issues, only a minority of respondents engage in such inappropriate habits.
