lchicine intoxication while receiving prophylactic doses of the drug. She d
eveloped gastrointestinal, central nervous system, cardiovascular and haema

atural grapefruit juice which, combined with long-term colchicine therapy a
nd a viral upper respiratory tract infection, increased her susceptibility

intoxication in this age group has been described in the English literature
