Poisoning with antihypertensive drugs: diuretics and potassium supplements

Diuretics are widely prescribed to treat hypertension and oedema. The increasing use of these drugs opens the possibility of an increase in deliberate or accidental self-poisoning. However, experience with overdosage and toxicity with the diuretics remains very limited. In general, supportive therapy by the reduction of gastrointestinal absorption, monitoring of vital signs and the correction of hypertension and electrolyte abnormalities are indicated.
