I think you misunderstood me – I haven’t had any contact with Ron Hines, the American vet. He had an article about Cardiomyopathy & Ferrets on his website

http://www.2ndchance.info/cardiomyopathyferret.htm

so I printed the information out and took that to my vet to ask if Kaos could be put on Spirolactone. I never contacted him but saw he had his email address on his site so passed that on to you if you wanted to ask him questions.

To muddy the waters, I found a site which talked about Benazepril being an ACE inhibitor drug and that is used with Spirolactone, then the potassium levels should be monitored.

You can read about it here

Of course that got me worried as Kaos is on Benazepril so I emailed my vet asking if she thought it was necessary to monitor Kaos’ potassium levels but she hasn’t written back.

Since that site is a general one about pet health, it could be that dogs & cats have a different requirement to ferrets when on the same medication but that’s only my guess. It’d be nice to hear back from my vet but I’m not holding my breath

digoxin is an herb med made from foxglove very toxic. used to help
with the heart beat functions.
Low levels of potassium cause the toxic levels to rise.
hints the dangers of using diuretics. I hope this helped you.

Yes, you’re quite right — all these different medications are so confusing.

I did a bit of googling and found something else about Kaos’ meds which makes me even more puzzled about whether what I’m giving her is the right stuff. I’ll write about it in my blog tomorrow morning.

Hopefully we can work out what the best results are for our ferrets when we share our experiences and results from various medications, etc.

That quote came from Ron Hines DVM, who is an American vet.

My vet told me that I shouldn’t worry about Kaos’ potassium levels because the Spirolactone would balance it out when given in conjunction with her Flusapex and Benazepril.

Because she hasn’t been prescribed Digoxin, I can only assume there’s no worry about toxicity.

Re your question about spirolactone, I honestly have no idea if that causes an increase in the serum potassium on its own or together with Digoxin.

If you go to Ron Hines’ website, you’ll see that he says people should email him if they want any further information about what he writes in his articles, so you might like to email him and ask him personally so that you get the right answer.

Sorry I can’t give you any definite answers but I would be really interested to know what the story is with the digoxin/spirolactone combination should you find out from him!

WHEN you said (Spirolactone can increase the toxicity and effect of digoxin so your pet’s digitoxin dose may need to be lowered.
It can also cause an (?increase in serum potassium,?)

DOSE the Spirolactone by its self cause an increase in the serum potassium?
or is it Spirolactone & digoxin together that causee’s this to happen?
I just wanted to be clear on this.
