General poisoning notes:

Golden-trumpet (Allamanda cathartica) is an indoor ornamental vine that is suited to greenhouses. It is considered poisonous, but firm evidence is lacking. The plant was once used as a cathartic. Ingesting the fruits may cause upset stomach (Kingsbury 1964; Hardin and Arena 1969).

There is a case of a young boy who was sucking the end of the stem of this plant. He subsequently became nauseated, and developed a high temperature and swollen lips. Some individuals develop a rash from the plant sap (Morton 1962).
