Real World Evidence on Perceived Effectiveness, Quality of Life Impact, and Public Attitudes Toward a Common Cold and Flu Medication: A Cross-Sectional Study

Upper respiratory tract infections such as the common cold are highly prevalent and impose a substantial health and economic burden, with many individuals relying on over-the-counter (OTC) medications for symptomatic relief despite limited real‑world evidence on perceived effectiveness. This non‑interventional, retrospective, cross‑sectional survey evaluated the product attributes most valued when selecting cold and flu medications and assessed perceptions of the effectiveness, quality‑of‑life impact, and overall attitudes toward MED‑LEMON. A total of 249 adults completed a structured questionnaire covering symptom relief priorities, medication attributes, perceived effectiveness, quality of life outcomes, and post-intake attitudes. Relief of fever, sore throat, headache, and sinus congestion, along with fast action, long‑lasting relief, and ease of use, were identified as key drivers of OTC cold and flu medication choice. MED‑LEMON was widely perceived as effective, with over 90% of participants reporting overall symptom improvement and strong relief of pain, headache, and fever. Adherence to the recommended dosing regimen was associated with better symptom control and improved quality of life, including sleep, emotional well‑being, and daily functioning. Overall attitudes toward MED‑LEMON were highly positive. From a public health perspective, these findings highlight the role of effective OTC treatments in supporting health promotion and responsible self-care during cold/flu period.
