The names of nearly one hundred works have been preserved by Galen, the Suda, and especially by authors writing in Arabic, who appear to have translated or had access to Arabic translations of all of his works. Ibn al-Nadim and Ibn Abī Uṣaybiʿa both preserve a similar list of books by Rufus of Ephesus, though Ibn Abī Uṣaybiʿa reports more titles than Ibn al-Nadim. Most of his works have been lost. His surviving works include: On the Names of the Parts of the Human Body On Diseases of the Bladder and Kidneys (1977 CMG Greek text) On Satyriasis and Gonorrhea Medical Questions On Gout (in Latin) On Nabidh (in Arabic) On Jaundice (in Latin and Arabic) Case histories (in Arabic) Some of this lost works include: On Regimen On Ancient Medicine On the Diet of Seafarers On Harmful Drugs On Injuries to the Limbs On Milk His short treatise Medical Questions, is valuable because its advice on how a doctor can gain information from a patient through questions offers a glimpse into the bedside manner of ancient physicians.
