title: [A frequent error in drug therapy: under-dosage].
abstract: Systematic studies on the occurrence and frequency of drug underdosage are rare, except in relation to noncompliance of patients and their physicians in different institutions (hospitals, outpatient divisions, practice). On the basis of four examples (digitalis preparations, diuretics, theophyllins and corticosteroids), seven rules are presented with a view to avoiding situations of relevant underdosage.
