Profound hyperkalemia associated with thromboprophylactic enoxaparin.

Hospitalized patients often require thromboprophylaxis to prevent venous thromboembolism. While multiple therapeutic options exist, low molecular weight heparins (LMWHs) are favored for their advantageous pharmacokinetic profile and limited adverse effects [Torres et al. 2010]. Enoxaparin, an LMWH, has been infrequently associated with mild hyperkalemia [Torres et al. 2010; Bengalorkar et al. 2011]. A case of profound hyperkalemia associated with prophylactic enoxaparin is reported.
