Greetings Tori and Jcee!
I have used both...Muffin had CRF most of his adult life and so
when his HCM was diagnosed we knew we were going to have to watch his
fluids and his potassium. He was on Tumil-K and suq Qs and that worked
very well for about a year and a half.
Then he started to develop fluid in his abdomen (called Ascites)
and he was re-diagnosed to "end stage" CHF...I was
devastated...but with all his excellent vet care and the support of
this group we got 6 more wonderful months together...which doesn't
sound like much, but we made the most of it and had a really wonderful
, extrodinary time together....it's a hell of a roller coaster, but
every effort is worth it because each day of good life is so very
He went on the Lasix and we also tried various other heart
meds...Norvasc and Lotensin added to his Atenelol which he had already
been taking since the HCM Dx. After reading all about the Lasix I
began to become terrified for his kidneys as we were no longer doing
any subQs....I thought the spironolactone would be a better choice....
My vet consulted with the Cardio and he approved of trying it, but
I have to say that for us, it did not work so well..Muffin was quite
old and already had issues with constipation...the Spiro made things
MUCH worse and he seemed unhappy and withdrawn while on it...we tried
it for a week to 10 days, but since it did help reduce his ascites we
changed back to the Lasix. Also, he had gotten Tumil K most of his
adult life and we had to withdraw it while on the spironolactone...I
don't know if that alone made Muffin feel worse of if it was the
Muffin's kidney numbers went up a bit after we atarted all this
treatment, but after about 2 months things started to improve,
numberwise and his creatnine actually began to fall so this was great
news.. He was already feeling/acting better after going back to the
Lasix. Very occassionally, when he hadn't pooped regularly enough or
if he seemed dehydrated, I'd give him 50-75 ml subqs but ONLY with the
vets approval. Often this small amount was enough to help him feel
better and have a good poop.
The lasix increased his thirst a lot and I made sure to have
several bowls of water around for him to be able to easily get a drink
whenever he wanted. I raised the bowls up to his chest height to make
it easier. Every day the water got changed and I also added a few
drops of Dandilion extract (for kidney) and Milk Thistle extract (for
liver) to all his water...he eventually got used to the taste and even
preferred it..."straight" water was now rejected! :-) HIs vet and I
believe that the Lasix kept the fluids from building up in and around
his lungs...this never was much of a problem for Muffin, and was no
problem after starting the Lasix. The Lasix did not seem to decrease
the ascites however and for that we did "taps" with a needle to
withdraw the fluids.
I know some other folks who have kitties with more advanced CRF
have used the Spironolactone ans it has worked well for them...each
case is different....and each kitties reaction is going to be
different. For us the Lasix worked much better. I hope this helps and
I wish you all the very, very best for you and Jcee.
