Pharmaceuticals, classified as emerging pollutants, are extensively applied in both human and veterinary medicine to treat various diseases. Their widespread application has led to their occurrence in water, soil, sediments, and living organisms. Even at trace levels (ng·L−1–μg·L−1), pharmaceuticals can significantly impact ecosystems and present threats to the environment and public health. Reliable analytical methods, such as liquid chromatography–tandem mass spectrometry (LC-MS/MS) and high-resolution mass spectrometry (LC-HRMS), are crucial for detecting and monitoring these compounds, including new or unknown substances. Removing pharmaceuticals from water remains challenging, as no single technique can completely eliminate all compounds and their toxic transformation products. Therefore, combining different treatment approaches, including membrane technologies, advanced oxidation processes (AOPs), and adsorption, into hybrid systems is necessary to improve removal efficiency and mitigate impacts on ecosystems and public health. In this review, a comprehensive overview of the occurrence of pharmaceuticals, their monitoring in food and water, and wastewater treatment is provided, highlighting current challenges and the need for further research.
