Discussions that mention furosemide

High & Low Blood Pressure board


Tweetee,

I am very fond of water pills (aka diuretics) to treat hypertension.
They work better than any other class in controlling BP for the minority of people whose hypertension is the results of improperly dealing with too much salt, like out diets usually have.

The best way to find out if you are in this group is to try HCTZ (hydrochlorothiazide) daily at around 50 mg. and see if that causes a large fall in your blood pressure (and WEIGHT!) If it does, then that is the drug class that should be the mainstay of your treatment. If not, then you will do better with ACEIs and ARBs which treat the hormones which most effect kidney finction.

Sometimes a combination of both types of drug will get good results...presumably in people who have BOTH kinds of hypertension.

I took HCTZ for several decades before switching to a different kind of "water pill", a loop diuretic called Lasix (furosemide) and I like the way it works...I've been taking it for almost a year. I take a large potassium supplement (800 mg.) because it tends to excrete potassium along with sodium.
I am taking a diuretic known as Furosemide.

As is common with loop diuretics, I have also been Rx'd a potassium supplement Klor-con. Suddenly the Klor-con was changed to Klor-con ER, the Extended Release formulation.

Is this the doctor's error? Is it serious?

I believe Furosemide although highly variable in individuals does its work within two hours and that the Klor-con ER would therefore likely be ineffective.

Anyone have any data or thoughts on this?
Note: I seem to have a vague recollection of having read a warning about this somewhere but I can't recall where and have not been able to find it by searching through anything readily at hand.
Fool's Gold,

Lasix (furosemide) is famous for its ability to cause potassium loss and thus is usually prescribed with potassium chloride. There are a zillion formulations and it is solely to replace the potassium lost by the furosemide. Really it wouldn't matter if you took the KCl 8 hours later, it would still replace the lost potassium. You shouldn't have to pay more than $15 a month for anything fancy...actually I gripe about paying that much becasue KCl is about as cheap to make as a pound of salt.

I'm not sure exactly WHY the slow release formulation. Perhaps it's safer becasue too much potassium into the bloodstream at one time can be dangerous? I'll look into it further. Most of the body's potassium is in the cells OUTSIDE the bloodstream.

Are you taking the 20 Meq dose or the 10?
Quote from syxx_35:
but I have been very happy with the combination of meds I am on.
Well, I congratulate you. I've not been happy with the meds that I am on and it seems that every renewal of a prescription involves errors in dosage or dosage-frequency and that slight substitutions of drugs are made without any ryme or reason.

I take some vitamin C on occasion to potentiate the furosemide but I have no idea if the ER versus normal release on the potassium chloride makes a difference.

I'm not yet at the point where I will start looking for an ice floe but if this is what old-age and ill-health are like, the ice floe is looking more and more attractive than dealing with quacks!
