'antiblennorrhagic' originates from Modern English, combining the prefix 'anti-' and the New Latin/Greek element 'blennorrhagia', where 'anti-' meant 'against', Greek 'blennē' meant 'mucus', and Greek 'rrhagia' meant 'excessive flow or discharge'.

'antiblennorrhagic' was formed in English by combining 'anti-' with New Latin 'blennorrhagia' (itself from Greek 'blennē' + 'rrhagia'). The medical combining forms developed through New Latin and later 19th-century English medical usage to yield the modern adjective.

Initially the formation signified 'against blennorrhagia' (measures or agents opposing excessive mucous discharge); it has retained this specific medical sense and is used for treatments or substances that prevent or reduce such discharges.
