My pharmacist tells me potassium sparing diuretics such as spironolactone are not completely, potassium sparing. Is this true?

My pharmacist tells me potassium sparing diuretics such as spironolactone are not completely, potassium sparing. Is this true?

Diuretics potassium: Potassium is excreted by the kidney in patients on sodium losing diuretics like Furosemide and hctz there is potassium wasting some of this loss can be decreased by low salt diets in patients who have low potassium u can offset this by drugs such as Aldactone (spironolactone) this is not a total block but if using Aldactone (spironolactone) check levels of potassium low potassium in absence. Of cause should be investigated. ...Read more

Which of the diuretics (thiazide, loop, potassium sparing) if you were to choose just one may be the best overall to treat hbp?

Which of the diuretics (thiazide, loop, potassium sparing) if you were to choose just one may be the best overall to treat hbp?

Depends: On multiple issues including kidney function. Certain diuretics work better with certain levels of kidney function/dysfunction. In general a thiazide is preferred as first line and particularly Chlorthalidone as it is long acting and potent. See your doctor for specifics as kidney function and potassium levels need to be followed. ...Read more

Are diuretics helpful to lower potassium in the blood. Looking for help to inform a friend whose test yday showed potassium at 5.5 & cretanine at 1.4.

Certain diuretics: Can lower the potassium level, but this is considered a side effect. Diuretics are NOT used to TREAT an elevated potassium level (hyperkalemia). If you really want to help your friend, encourage him/her to get prompt medical care. My best. Dr. Anne ...Read more

Battling low potassium for weeks ranging from 3.1 to 2.7. Taking diuretics and K supplements. I fell down today. Is this related? Today it's 2.9

Battling low potassium for weeks ranging from 3.1 to 2.7. Taking diuretics and K supplements. I fell down today. Is this related? Today it's 2.9

Low potassium levels: Hypokalemia (H) can be caused be caused by diuretics (D). They do this by two mechanisms. One is by potassium (K) losses in the urine. The other way is by magnesium (M) losses caused by the D. Patients with low M levels will not be able to increase their K level until the M is repleted. Check your M level and if low eat foods rich in M, such as cashews, or try some M supplements. Get a blood test. ...Read more

Why is there an edema when you have Cardiomyopathy? I was given a diuretics. Now why do you think is it that I was given a potassium chloride?

Poor heart function: If the heart is weak, then it does not pump forward well, and fluid backs up in places - ankles/feet; lungs; belly. Diuretics help drive excess fluid and salt out of the system. Often diurectics also drive potassium out in the urine - hence extra potassium is needed to be taken in. ...Read more

Low K: K of 2.9 on diuretics and K. Set for surgery. How to get K up? Check with team: Stop diuretic? 1. Find cause of lo K and correct first. 2. Recommend DASH eating plan Na <1, 500 mg and K >4, 700 mg as will correct K immediately because low Na in stops urine K leak. Check with team bout DASH, get book & do Chap 9 EXACTLY.

Dear MDs: Although I eat very rich Potassium diet, my K level always <=3.3. I take 12.5 mg diuretic (hctz). How much of K does 12.5 mg HCT depletes

Dear MDs: Although I eat very rich Potassium diet, my K level always <=3.3. I take 12.5 mg diuretic (hctz). How much of K does 12.5 mg HCT depletes

Enough: Enough to have low blood potassium and not enough potassium in your food to correct it. However, there is a medical condition in which your adrenal gland is producing abnormal amounts of a hormone called Aldosterone that prevents the kidney from reabsorbing potassium. I would stop the diuretic and re measure your potassium. If normal, shift to another med. If it remains low, get back to your MD. ...Read more

What kind of test will nephrologist do to determine cause of consistent low potassium? I do not take diuretics or have GI prob.

Hypokalemia tests: Some of the tests used to find a cause for hypokalemia, low potassium are: •serum renin, aldosterone, magnesium and cortisol, •24-hour urine aldosterone, cortisol, sodium, and potassium, •pituitary imaging to evaluate for cushing syndrome, •adrenal imaging to evaluate for adenoma, •evaluation for renal artery stenosis and •enzyme assays for 17-beta hydroxylase deficiency. Good luck. ...Read more

Dear MDs: Although my daily diet is > 5000 mg of K rich food/fruits, my K is <3.4. By how much would 12.5 mg diuretic (hctz) decrease potassium level?

Can be significant: HCTZ (hydrochlorothiazide) can certainly do this! Also contributing can be subtle things like diuretic effects of alcohol or caffeine, even large amounts of licorice! Some forms of hypertension are associated with low K to begin with ("hyper aldosterone states") and are very sensitive to even low doses of HCTZ (hydrochlorothiazide). ...Read more

Taking Benicar (olmesartan) 40/ hct 12.5 but my potassium is 3.0 as the diuretic is causing potassium loss. Any other meds to control htn & replace hctz diuretic?

Low potassium levels: Your low potassium (k) could be worsened by magnesium (m) loss due to hct. Your k won't be normal unless the m is repleted. At your age, with a history of cardiac disease, you may have some chronic kidney disease. Hct won't work if you've <50% of your kidney function left. If your BP isn't controlled on your meds, ask your doc to rx Furosemide (f) as a diuretic. F causes urine loss of m and k too. ...Read more

My carbon dioxide level is 29. No smoking/asthma. Should I be worried? Potassium was a 3.3 and calcium was a 10.1 due to diuretic. What do I do?

See below: Elevated CO2 (aka metabolic alkalosis) also most likely related to your diuretic and, as an isolated abnormality, is nothing to be overly concerned about. Low potassium and high calcium, glucose, uric acid, and CO2 are amongst the most common side effects and lab abnormalities to occur due to diuretic therapy. You should discuss these results with your MD along with potassium supplementation. ...Read more

CAUSE CONSTIPATION: Diuretics has no effect what so ever on anal fissure better or worst saying that if the diuretics will end up causing dehydration bad enough to cause constipation then yes that could cause the anal fissure to be worst

Low k: hypokalemia is shift inside cells, increased losses either Gut or kidney and low intake with some loses. Based on your info you need a full exam and a urine study to assess for losses by the kidney. Also what is your BP and serum bicarbonate (sodium bicarbonate). This information offers clues. Suggest see a kidney doc for work up. All this is assuming all your labs were repeated and low k was persistent. ...Read more

I was taking lisinipril with the water pill, but my potassium got too low and he took the water pill away. Now im retaining water feet swoll, now what?

Retaining edema: You need to speak to your doctor about your water retention. Diuretics waste not only potassium (k) in your urine, they also waste magnesium (m). The reason why your k was low could be due to your having a low m as well. You could go back on your diuretic and take supplement k. If your m was low, you may also need m supplements. Retention of fluid is a dangerous thing. Speak to your physician asap. ...Read more

On lisinopril/hctz 20/12.5mg for hypertension and spironolactone 50 mg foracnehow much potassium should I eat a day? And being on two diuretics safe?

Probably OK: Spironolactone can in rare cases cause high potassium, but in a young healthy person usually not an issue. To be safe, have your potassium levels checked (blood test) but you may generally eat whatever you want. The combination of diuretic is generally considered safe, but as I said, get your potassium level checked. ...Read more

Diuretic (Definition)

By strict definition, a diuretic is any medicine causing increased urination. More practically, a diuretic is a medicine causing the kidney to secrete excess fluid by blocking the re-absorption of either water itself or electrolytes like sodium (primarily), potassium, chloride and bicarbonate (sodium bicarbonate). These medicines are effective treatments for many disorders including ...Read more
