Customer Question

I just started taking Losartan 12.5 me for 145-156 blood pressure. I'm confused about the potassium idea. Should I avoid high potassium foods. What about magnesium supplements. It's confusing.

High potassium in the blood may occur; risk factors include renal dysfunction, diabetes mellitus, concomitant use of potassium-sparing diuretics, potassium supplements and/or potassium containing salts. Use cautiously, if at all, with these agents and monitor potassium closely. Do you take any other medications including over-the-counter pills and herbs? Any other medical problems?

Hi there,
This is Dr Basu, experienced Internal Medicine Specialist.
I am here to address your concerns and provide great service.

If your kidney function is normal, and serum potassium in normal range, then you do not need to change your diet.

Losartan will not cause any significant increase in potassium in normal individuals.

Kidney will eliminate excess potassium as they do normally.

You can take magnesium supplement as well.

But the magnesium level should be checked to prevent any excess.

After starting on losartan, blood tests measuring serum potassium and creatinine levels are recommended after 2 weeks.
Best wishes,
