DIURETICS AND THEOPHYLLINE
Furosemide is reported to increase, decrease or to have no effect on serum theophylline levels. Both theophylline and loop or thiazide diuretics can cause hypokalaemia, which may be additive.
If both drugs are used be aware for the potential for changes in theophylline levels. Consider measuring theophylline levels, and make appropriate dosage adjust- ments as necessary. It may be prudent to also monitor potassium levels.
