Although thiazide-like diuretics were initially known to have little or no metabolic side-effects, some later evidence showed some of their adverse reactions. We aimed to survey their side-effects in long term administration. We conducted a prospective pharmacovigilance study on the metabolic side-effects of indapamide in the Vth Internal Medicine Clinic Iași, Romania, between 2016 and 2018. Thirty hypertensive patients were monitored regarding glycaemia, uricemia and kaliemia before starting indapamide administration (T0), after at least three months of administration (T1) and after at least some other three months of withdrawal (T2). A significant increase of glycaemia and uricemia appeared after three months of administration of indapamide, which disappeared in most of the cases after stopping the treatment. A significant decrease of kaliemia was also noted under treatment and it was reversible after stopping indapamide. The incrimination of indapamide in producing hyperglycaemia, hyperuricemia or hypokalaemia was certain or probable in eight cases and possible in five cases according to the WHO-UMC (2010) algorithm for causality assessment. Thiazide-like diuretics may expose to the same metabolic risks as thiazide-type diuretics. Precautious administration in case of already present hypokalaemia could be protective. Larger studies are needed in order to define the dose, the period of administration or other associated factors that could expose to an increased risk of side-effects.
