Potassium - Hyzaar (Hydrochlorothiazide, Losartan Potassium) Interaction

Interaction Details

Hydrochlorothiazide, Losartan Potassium is classified as belonging to the following category: Angiotensin Receptor Blockers (Arbs)

Using ARBs with high doses of potassium increases the risk of hyperkalemia.
ARBs block the actions of the renin-angiotensin-aldosterone system and reduce potassium excretion. Concomitant use of these drugs with potassium supplements increases the risk of hyperkalemia. However, concomitant use of these drugs with moderate dietary potassium intake (about 3775-5200 mg daily) does not increase serum potassium levels.
