Loop diuretics are used for hypertension only in specific situations: concurrent heart-failure oedema, advanced CKD (eGFR &lt;30) where thiazides fail, or resistant hypertension as an add-on. For standard hypertension, choose a thiazide, ARB, ACE inhibitor, or calcium-channel blocker instead.<\/p>\n<h3 class=\"wp-block-heading\">Will Lasix affect my potassium?<\/h3>\n<p>Yes &mdash; Lasix <strong>sni\u017euje<\/strong> drasl\u00edk zv\u00fd\u0161en\u00edm jeho vylu\u010dov\u00e1n\u00ed v dist\u00e1ln\u00edm tubulu.
