Abstract
We reported here a four-year-old girl who developed choreoathetosis of right upper and lower extremities after treatment for allergic rhinitis and bronchial asthma with seven days of oxatomide and following three days of theophylline. Her involuntary movements disappeared about two weeks after cessation of the prescription and have not recurred since then. It might be possible that treatment with oxatomide followed by theophylline induced a similar pathophysiological condition to that of paroxysmal dystonic choreoathetosis.
