when taken orally it can pull intra-muscular water as well as sub-q leaving you flat and small...and its dangerous so have pedialite on hand
Aldactone is much better, dyazide is also a great and slightly stronger option.
thursday, friday, saturday you water load, drink so you are urunatung frequently this will start your body flushing...then sunday cut your water back to less than 1 litre for the day, just sipping enough to get your food down.
Dosage is usually every 8 hours, but some go 4 to 6hr
You have to also really evaluate and control your sodium and potassium levels for no cramping on super low water.
I'm sure some vets will add their support here and make some changes.
Please.. Be careful. Aldactone or dyazide is a better choice, and remember lasix will really flatten you out at times
