An Overview of Hyzaar Side EffectsAs with any medicine, there are possible side effects associated with Hyzaar® (losartan potassium-hydrochlorothiazide). However, not everyone who takes Hyzaar will experience side effects. In fact, most people tolerate it well. When side effects do occur, in many cases they are minor, meaning they require no treatment or are easily treated by you or a healthcare provider. Serious side effects can occur, but are less common.
(This article covers many, but not all, of the possible side effects of Hyzaar. Your healthcare provider can discuss a more complete list of Hyzaar side effects with you.)
