I am 53 years old, 5'3", excellent health and recent full blood panels completed with everything wnl. I'm very athletic & normally weigh about 120 lbs.
I was bulimic from age 18-20, and worked through the bulimia on my own.
I was placed on phentermine by a "diet doctor" in my 30s which led to a weight of about 112 & a physiological addiction to phentermine. I worked through that as well (took a few years)
I am physiologically- and possibly psychologically- addicted to Lasix high dose (500-1000 mg or more). I want off. I reduced the lasix to 250 mg (1/2 tab) for the last 3 days. I have gone up 5-6 lbs. The one time I tried stopping cold turkey I went up 10 lbs in 3-4 days. I want to reduce again to 125 mg, and then get a pill cutter to reduce to about 60 mg, then down to 30, then off.
I am scared regarding the weight gain. I have started a diet (normal- goal of 1 lb/week as I would like to weigh 115-117, which is when I look and feel my best).
Any idea as to how long I will gain water as I reduce the lasix? I am urinating normally- that was never disturbed. I take potassium supplements.

I have been on Viibrid for a little less than a year to help with anxiety and mild depression (I'm a psychologist- mild as in DSM "mild")following the suddent death of my spouse of 15 years. (date of death 08/16/2011)

viibrid 40 mg

Thank Peri
I'm sorry about this dependence you have.
The weight gain from lasix will be instantaneous.
All the weight you gain will be within one week.

thank you.

I'm sorry about it too.

Any idea as to how much weight & how long it will take to resolve? I'm a competitive amateur ballroom dancer, & cross-train by cycling 40-60m/week. I sweat easily and profusely.

Also: should i increase liquid intake? & if so, by how much, & should I use pedialyte for electrolyte replacement?

Thanks for this reply
This is a high dose of lasix so I suspect about 10-15 lbs.
It will balance out after a couple more weeks.
You will likely lose some of that back when your system normalizes
I would drink 6-8 glasses per day that's it.
Water is fine. electrolyte drinks are better.
