Hello!
Thank you for asking on HCM!
Regarding your concern, i would explain that when the patient is on high dose diuretics, especially when renal function is normal, it is highly recommended to be aware of electrolytes loss by increased urine output.
So, potassium supplements are necessary to substitute daily losses.
Daily blood electrolytes tests are the best guidance to decide the daily dose of supplements, as there are not fixed and predetermined doses for this purpose.
So, facing the increased dose of daily
lasix, and her weight, seems that those potassium supplements are necessary.
A correct judgement would be available if you upload the exact blood potassium level and its trend changes.
Hope to have been helpful to you. Greetings! Dr. Iliri
