Among the second group, 35 patients stopped their treatments, eight changed the administration schedule, and four took all the daily doses in one intake.

The authors warned about the high risk of drug interactions in such cases. In fact, a 57 year old woman with heart failure experienced side effects of digitalis after being treated with both a thiazide diuretic and …
