I may need diuretic, but hctz (hydrochlorothiazide) and metoalzone both caused hyponatremia, 125. what are available options if diuretic is needed in future?

Lasix (furosemide): Lasix (furosemide) will probably work for you. It tends to raise the serum sodium.

Depends: It depends on why you need diuretics in the first place; for some patients, Lasix (furosemide) will work, but for others, it will be contraindicated. Discuss with your doctor or get a referral to a nephrologist.

Diuretics: If you take a diuretic (d) one of the side effects is a low sodium level, hyponatremia (h). You can try to avoid h by weighing yourself daily in the morning, at the same time, in your bed clothes and recording the date and your weight. If you lose more than 2 lbs., hold the d for just 1 day. Too rapid weight loss, i.e. > 2 lbs/day can lead to h. If h is a problem, discuss it with your physician.
