The purpose of this study was to determine if clinically effective serum levels of theophylline have an inhibitory effect on intradermal tests for allergic hypersensitivity. Intradermal testing using the threshold-dilution technique was performed in 9 patients, 7 of whom were sensitive to 2 antigens. Testing was performed over a 6-hour period after theophylline administration and compared with the control results. Inhibition of the end-point was demonstrated with 12 of 16 antigens tested associated with serum theophylline levels ranging from 7 to 20 microgram/ml. Marked inhibition of the intradermal tests, that might have clinical significance, only occurred with 4 antigens.
