Described is a case of severe hyperkalaemia and hyporeninaemic hypoaldosteronism due to the inappropriate use of mefenamic acid. The causes of hyporeninaemic hypoaldosteronism are discussed and the importance of a detailed drug history emphasised.

UI	MeSH Term	Description	Entries
D006994	Hypoaldosteronism	A congenital or acquired condition of insufficient production of ALDOSTERONE by the ADRENAL CORTEX leading to diminished aldosterone-mediated synthesis of Na(+)-K(+)-EXCHANGING ATPASE in renal tubular cells. Clinical symptoms include HYPERKALEMIA, sodium-wasting, HYPOTENSION, and sometimes metabolic ACIDOSIS.

D006947	Hyperkalemia	Abnormally high potassium concentration in the blood, most often due to defective renal excretion. It is characterized clinically by electrocardiographic abnormalities (elevated T waves and depressed P waves, and eventually by atrial asystole). In severe cases, weakness and flaccid paralysis may occur. (Dorland, 27th ed)	Hyperpotassemia,Hyperkalemias,Hyperpotassemias
