This study aimed to investigate Romanian physicians’ awareness, recommendation practices, and opinions regarding the use of Foods for Special Medical Purposes (FSMPs) products. A total of ten physicians were interviewed using a structured questionnaire, and their responses were analysed using thematic content analysis. The study found that physicians were aware of FSMPs and recommended them to their patients based on nutritional deficits, weight loss, or deglutition impairments. In addition, disease stage, treatment scheme, taste, affordability, and availability were identified as factors influencing the recommendation and use of FSMPs. While physicians generally did not consult clinical trials, clinical experience was deemed essential for recommending FSMPs to patients. Patients’ feedback regarding the usage and sourcing of FSMPs was generally positive, with some expressing concerns about the availability of different flavours and the costs of purchasing the products. This study concluded that physicians play a vital role in recommending FSMPs to patients and ensuring they have the necessary nutritional support during treatment. However, it may be imperative to consider the provision of additional patient education materials and fostering collaborative efforts with nutritionists in order to optimise the prospects of positive outcomes in oncology treatment, while simultaneously alleviating the financial burdens faced by patients.
