While the use of macrolide antibiotics, lincomycin, allopurinol, cimetidine, isoprenaline, beta-blockers, oral contraceptives, epoksatsinom and vaccination against influenza may increase the intensity of the action, which may require dose reduction of theophylline.

Theophylline increases the likelihood of side effects of glucocorticoids, mineralokortikosteroidov (hypernatremia), means that excite the central nervous system (increases neurotoxicity).

The drug inhibits the therapeutic effects of lithium carbonate and beta-blockers.

Theophylline potentiates the effect of diuretics due to an increase in glomerular filtration and tubular reabsorption reduction.

Precautions theophylline administered simultaneously with an anticoagulant.

Antidiarrheal drugs and chelators reduce the absorption of theophylline.
