What does convulsionary mean?
'Convulsionary' is a rare but legitimate English adjective describing anything related to, characterized by, or productive of convulsions — the sudden, violent, involuntary contractions of muscles seen in epileptic seizures, certain fevers, and some toxic reactions. In modern practice it has largely been displaced by the far more common adjective 'convulsive', so encountering 'convulsionary' today usually signals formal, clinical, or deliberately literary prose. The word also survives as an obscure noun denoting a person prone to convulsions; this sense is best remembered from eighteenth-century France, where the ecstatic sufferers known as the Convulsionnaires of Saint-Médard gave it a brief notoriety. Derived from Latin roots meaning to pull or tear violently ('con-' plus 'vellere', to pluck), it belongs to a small family including 'convulse', 'convulsion', and 'convulsive'. For readers and writers, it is worth knowing as a precise, if seldom-used, alternative — useful when variety of diction matters more than familiarity.

"Doctors monitored the child closely for any convulsionary activity after administering the drug."
Largely superseded in modern usage by 'convulsive'; retained mainly in older medical texts and formal writing.

In 18th-century Paris, worshippers at the graveyard of Saint-Médard who fell into religious trances and violent fits became famous as the 'Convulsionnaires' — a name built directly on this very word.

Etymology of convulsionary
Convulsionary derives from the Latin verb 'convellere', formed from 'com-' (together) and 'vellere' (to pluck or tear out), which passed into English via the noun 'convulsion'. The English word 'convulsion' is attested from around the early 17th century, and 'convulsionary' emerged shortly afterward as an adjectival form describing things marked by such spasms. It shares this Latin root with 'convulse', 'convulsive', and 'evulse'. Its noun use was reinforced by the fame of the eighteenth-century French Convulsionnaires, devotees whose violent ecstatic fits made the term a byword in contemporary Europe.
How convulsionary is actually used
The adjective form is uncommon in modern English; 'convulsive' is strongly preferred in both medical and general contexts. The noun sense survives mainly in historical writing about the French Convulsionnaire movement of the 1730s. The word carries a clinical, formal register wherever it does appear.
