Prevalence, Patterns, and Determinants of Non-Prescription Antibiotic Acquisition and Self-Medication in South Asia: A Systematic Review and Meta-Analysis
This systematic review and meta-analysis reveals that nearly half (45.5%) of antibiotic acquisitions in South Asia occur without a prescription, with significant country-level variations and a strong preference for WHO Watch-category drugs driven by convenience, cost, and weak enforcement, thereby posing a critical threat of antimicrobial resistance.

In many parts of the world, a visit to a local pharmacy is the first step for anyone feeling unwell. It is a place where people seek quick relief for a fever, a cough, or a stomach ache, often without seeing a doctor first. In these settings, antibiotics are powerful medicines designed to kill bacteria, the microscopic organisms that cause infections like strep throat or pneumonia. However, these drugs do nothing against viruses, which cause the common cold or the flu. When people take antibiotics when they are not needed, or when they take them without a doctor's guidance, the bacteria they are meant to fight can learn to survive the medicine. This survival leads to a growing global crisis known as antimicrobial resistance, where common infections become harder and sometimes impossible to treat. South Asia, a region home to nearly a quarter of the human population, has become a critical hotspot for this problem, driven largely by how easily people can buy these life-saving drugs without a prescription.
A new study brings together evidence from across this vast region to understand just how common this practice is and what is driving it. Researchers gathered data from twelve different studies conducted in countries like India, Pakistan, Bangladesh, Nepal, and Sri Lanka. These studies included surveys of thousands of people and direct observations of what happens inside pharmacies. By combining all this information, the team calculated that nearly half of all antibiotic purchases in South Asia happen without a valid prescription from a licensed medical professional. This means that for every two people buying antibiotics, one is likely doing so without a doctor's order. The situation varies significantly from country to country, with the highest rates found in Nepal, where the study suggests that more than seven out of ten antibiotic acquisitions are non-prescription, and the lowest in India, where the figure is closer to one in four.
The way researchers uncovered these numbers involved looking at two different types of evidence. One type came from asking people in their homes or communities what they had done, which showed that about three in ten people admitted to buying antibiotics without a prescription. The other type came from a method called a simulated client audit, where researchers acted as customers with specific symptoms to see what the pharmacy staff would actually do. In these direct tests, the results were stark: when a person walked into a shop asking for help with a minor illness, the staff handed over antibiotics without a prescription in nearly all cases, with rates reaching as high as ninety-seven percent in some instances. This gap suggests that while people might say they know better, the reality of buying medicine on the street is that it is almost always available without a doctor's note.
The study also looked closely at exactly which medicines were being sold. The drugs most frequently bought without a prescription were broad-spectrum antibiotics, which are powerful medicines capable of killing many different types of bacteria. These specific drugs, often used for serious infections, were being handed out for minor, self-limiting conditions like a simple cough, a sore throat, or a bout of diarrhea that would likely go away on its own. This pattern is concerning because it exposes the community to strong medicines they do not need, speeding up the development of resistance. The researchers found that the main reasons people turn to pharmacies instead of doctors are practical: it is cheaper, faster, and more convenient to walk into a shop than to wait for a medical appointment. For the shop owners, selling these drugs is a way to make money and keep customers happy, creating a cycle where the demand for quick fixes meets the supply of unregulated medicine.
Despite laws in many of these countries that require a prescription for certain antibiotics, the rules are rarely enforced. The study points out that the people who run these pharmacies are often under no pressure to follow the regulations, and the public remains largely unaware that taking antibiotics for a viral infection is ineffective and potentially harmful. To stop this cycle, the researchers argue that simply having laws on the books is not enough. They suggest that governments must actively enforce these rules, perhaps by using clear visual markers on medicine packaging to show which drugs require a prescription, and by finding ways to change the financial incentives for shop owners so they are rewarded for following the rules rather than breaking them. Without these changes, the region will continue to face a rising tide of infections that standard medicines can no longer cure.
