I have been taking aldactone 50 mg a day for almost 3 months for acne. I have noticed some improvement, however, I thought I would have fewer breakouts. I have noticed that I've almost gained 10 pounds without changing anything in my daily diet and exercise routine? Will the extra pounds be lost once my body adjusts or will I continue to gain more weight the longer I take the drug? I want clear skin, but not at the cost of a nice figure I've worked hard on!
Spironolactone - Will weight gain with aldactone usage go away once the body adjusts?

Wow, I’ve been taking this for a few years for elevated BP but never realized the correlation between Spiro and my weight gain. I was chalking it up to aging and post-menopausal life. It supposedly helps with androgenic alopecia which I also have, and it seemed to help when I was on 100mg. Last year my cardiologist switched me to 50 mg of Spiro and 20 mg furosemide (Lasix) saying it was a better combo for my mild hypertension. My hair has been falling out, BP normal, but the weight gain steady. I am active, eat mostly plants, count calories but can’t get rid of the bloated belly, butt, thighs. I was going to ask to increase the Spiro back to 100 mg but after finding this thread, I’m getting off it!
To top it off, I had an estrogen + breast cancer 7 years ago and should never have been prescribed this drug as it has estrogenic effects!
I didn’t know it had estrogen effects. I’ve been on it for a very long time, and I also had breast cancer. And I am also been getting weight mysteriously. Was very sick in the hospital last year with anabiotic resistant pneumonia and lost hair. It was unbelievable. Hair just fell out. I had no protein in my body. I had nothing everything was gone. It was bizarre so I started concentrating on getting more protein and B12 and folate.
I was prescribed this drug for hair loss in my early 40s - I am now 68. The drug went by its generic name Aldactone. I was and always had been a size 10 and could eat anything I liked without gaining weight. Very soon after taking Aldactone I stacked on the weight. The doctor said not to worry I needed a few pounds. I took this for a year or so then weaned myself off it. At the end of that year I was a size 14 and have had trouble with weight gain ever since. I am now a size 16 and have to watch what I eat. I believe that drug altered my gut microbiome. It did stop the hair loss, but it came at a heavy price. I would tell anyone not to take this drug unless it is absolutely necessary. For acne use Greek Yogurt mixed with green tea as a mask daily and use a cream containing Azelaic Acid.
Was taking only 12.5 for low potassium and started to gain weight after about 4 months gradually. I have weighed the same pretty much my entire adult life- 144 lbs. Tall and naturally slender, active, clean eater. When the scale hit 149 I put two and two together that it had to the be the Spiro. Did some research and found the info about how it affects your hormones which FREAKED me out. Went off it after being on it for just over a year on it, and have continued to slowly gain despite locking down my calories even further and working out more. It's been 10 months since I've stopped taking spironolactone yet I am barely hanging on to this 10 pound gain by eating in a calorie-deficient, but I really don't have much of an appetite anyway. It has absolutely wrecked my metabolism. I have a belly of fat, a layer of fat on my hips and my thighs rub together. I don't even recognize myself anymore.
After going to my PCP, my OB-GYN, and my Cardiologist who all blew me off with the "it doesn't cause weight gain" even though my scale said 154 and I was eating more clean and was more active than I've ever been in my entire life. I finally found a new OB-GYN who tested my hormones and cortisol (testosterone nearly zero; cortisol high), and also did a full thyroid panel... T4 and T3 also very low (other docs tested only TSH which was on the high side but "normal" so proclaimed "just fine!"). I've been on NP Thyroid and Testosterone for about 6 weeks now and I feel like I'm slowly, so very slowly, pulling out of this slump. Scale has not budged but I am feeling less sluggish and looking not quite as squishy in my mid section. Dr. may consider adding progesterone to my therapy as well when I get my labs done in another 4 weeks. I hope this provides some positive hope to others. Find a doctor who will test your hormones and do a full thyroid panel. This stupid med can wreak HAVOC on your hormones which can also cause a domino effect. The gas lighting by the doctors when you raise your concern makes it 1000x worse. I am furious with myself for not researching this first. I hope this helps others doing their research.
I’ve been on spiro for maybe 2 years. Started with 10mg and have been at 50mg for the past year. Im 36 4’11”, and slowly gained 10-12lbs. I kept relating it to age even though i am active…i jog 2miles a couple of times a week…take hot yoga and even some jiu jitsu classes.
For me…even though the weight came on slowly I feel that it was lost via water weight. I felt in shape at times, but I'd get dehydrated quickly. And my skin looked amazing- I started the meds for acne.
The last few months my libido has dropped and it wasn't until I completely missed my last 2 periods that I realized it was the meds. With the weight gain, I took a preggo test knowing i wasn't preggo lol.
Like a lot of you, I've tested for thyroid issues, came off my birth control, paid close attention to my diet and exercise to see what I was doing wrong and here we are. I stopped taking spiro about 3weeks ago and I actually gained another 5lbs in the first couple days.
I'm going to chug through and pay attention to my diet and exercise…mood etc so that I can post an update about when I finally regulate.
So far my mood seems better and libido is back. Period is still MIA and weight is here.
READ FOR PEACE OF MIND!!! Hi guys. So I’ve been keeping up with this thread as well as many others for the last 4-5 months. I made an account just for this matter. I went on spiro January 2021 (for acne), got off of it January 2022. So I was on it for 1 year. From the months of May ‘21 - July ‘21, I put on about 15 pounds. Like all of you, my activity, food intake, stress, etc had not changed. I’m 5’3” and weighed 118ish when I started these meds. I ended up at 132ish for the last 6 months I was on the meds. I wouldn’t gain or lose. It was bizarre. And I have much experience with macro tracking, fat gain/loss, so it’s no issue for me to have a goal and hit it with proper calorie intake. So to do this and not see anything change, I knew something was wrong!
I am also a Hashimotos/Hypothyroidism patient on Synthroid, so I assumed this was a thyroid issue for many months. After checking that several times, getting healthy results, I finally looked into spiro and weight gain.
I was in shock seeing what you all have gone/are going through and what I had just experienced all from a medication solely for ACNE. It’s so incredibly aggravating and believe me I understand the frustration and emotional rollercoaster the weight gain and weight loss resistance from this medication causes.
Here’s what I did: after constant research, it became apparent that spiro can cause estrogen dominance/low progesterone. I had my hormones checked and we found that my progesterone was basically nonexistent, but my estrogen was fine, resulting in estrogen dominance. So for 12 weeks/3 cycles, I took bio identical progesterone to help balance. We’ve achieved that, and about a week ago, for the first time in over a YEAR, the scale has started to slowly trend downward. I don’t wanna speak too soon, but I do feel confident that I’ve reached full recovery from these meds.
Obviously the only way to lose fat is to be in a caloric deficit so I’ve gone about this through diet and calorie restriction. Not weightlifting at the moment. Even a month ago, calorie restriction still didn’t work for me. The scale wouldn’t budge. So now that it is, I can say to just give it time and get treatment if needed to help speed up the balancing process. See a HORMONE SPECIALIST. It’s obviously a matter of patience and letting your body figure itself out.
Don’t worry and don’t think you will never lose fat again. You will and it just takes time to adjust back to a healthy balance. Expect to get back to your old body and KNOW it will happen because that helps speed up the process too. Our minds are powerful and what we tell ourselves, we experience. If you have any questions, feel free to reach out. Sending love and positivity to you all!
Is there anyway I could reach out to you to talk to you more about this? I’m experiencing the same thing as you and it seems like we are similar in height/weight.

I was on it for 4 months and the 10 pounds came on immediately. I am an active person and count my calories and it didnt make sense why I would be gaining weight. I stopped taking it and my face is the same as it was while i was on it. I personally wouldn’t recommend this drug.
Hey everyone here is an update to my original post. I have now gained 50lbs since 2019 and my dermatologist swears it's not the spironolactone. I'm so extremely unhappy with my body that I'm actually having gastric bypass this week. My BMI is 30 which is on the low end so I'm paying out of pocket for it. I know this is extreme but I cannot take this extra weight anymore. I've been off spironolactone for at least 8 months consistently working out lifting weights in a 500 calorie deficit and not one dam pound has come off. As others stated I'm extremely bloated and look pregnant. I can't fit into any of my clothes and it's extremely depressing as I'm sure y'all know. I've been to so many endocrinologist and functional medicine doctors and all say my hormones are fine except my testosterone which is suppressed by the spironolactone. I wish I never tried this drug although my skin looked absolutely AMAZING while on it the weight gain isn't worth it. PLEASE think twice before getting on spironolactone at any dose!
I had my gastric bypass on Tuesday and I don't regret it at all. Spironolactone needs to be taken off the shelves especially when dermatologists won't admit that this can cause massive weight gain. My bypass surgeon said he has had several patients who have gained weight AFTER their bypass. He told me under no circumstances am I to ever take it again.
Same boat and i really do think its from spironolactone
I took spironolactone for several years. The first 1.5 years everything was fine, but then I suddenly started gaining a lot of weight (about 10-15 kg or 22-33 lbs).
My thighs got huge. They now rub together which they have never before as I have wide hips. I have cellulite very visible all over my thighs now when before it was more only sides or when I pinched my skin.
I also got cellulite on my arms. They're big and flabby now.
Even my underarms are swollen.
I also got a huge tummy pouch which I never ever had before, as well as in the area below. It wiggles so much that I have to wear high waist underwear. When I sit I look like the Michelin Man when I never had a single roll of fat on my stomach. My stomach/hip area looks wider in general.
I also have fat rolls on my back now. At some point they clashed and squeezed together when I was walking.
Even a couple of months before the weight gain started, I've noticed that the top of my feet were slightly swollen. The swelling doesn't seem to dependent on sth. I've always had thin feet where you could see every bone and tendon.
It's also very, very soft and wiggly. When I tip slightly against one side of my stomach I can see and feel it travelling to the other side. When I tip against my knee it travels up my whole thigh. Like if you throw a stone into water creating waves. Same on my arms and back. My normal body fat is more thick. I suspect it's water.
Decreasing my calorie intake down to only 500 kcal/day for months didn't do much even though I can say that I lost a little bit of weight. But I still don't recognize myself.
I recently switched to drospirenone (progesterone which is related to spironolactone) as I suspect the weight gain was due to low testosterone and high estrogen. I think it's getting better, but it's too early to say for sure..
I am in the same boat. Doc put me on in October for testosterone dominance and acne. Since then, i have gained 10 pounds! I have never been more active in my whole life- 1 hr cardio a day with 45 min strength training. I continue to gain weight. I cant lose it. I eat a balanced modified diet as well. Soooooo frustrated!!! I am not going to be taking this drug anymore. Ridiculous.
I have been on Spironolactone and birth control since March 2019.
It was prescribed to me for female pattern hair loss. Since then I have determined that a medication I was using for depression was causing the intense hair loss. Discontinued it, but decided to stay on the Spironolactone until the antidepressant was out of my system. Wanted to keep hair on my head until my my body fully recalibrated.
I’m on a carb free, sugar free, processed food free diet and exercise. And have been gaining weight like crazy. Same as everyone else... abdomen, legs, thighs and butt.
When I noticed the weight, I assumed it was the pill so I stopped taking it. But the pounds have continued to pile on.
I’m so glad I found your stories.
Thank-you. Definitely going to speak to my physician and dermatologist about this.
I’m so sorry this has happened to each of you but also thankful to know that I’m not the only one Z this has happen too since starting this prescription.
I started gaining weight shortly after my GP prescribed this medication to me for an ongoing cystic acne problem.
For months I have been trying to figure out why I all of a sudden started gaining so much weight, especially in my stomach, thighs, butt, arms, etc. I have been the exact same weight my entire adult life (tall and slim with no signs of cellulite) now I have grown out of all of my clothes, (have had to buy two size bigger clothes) and have cellulite on the back of my thighs and butt and the tops of my arms move when I wave them. I am completely mortified about this. My face is free from acne but I feel so bloated and I look a 3 months pregnant. Not to mention, if one more person says it’s probably just due to the fact that I’m not getting any younger, I think I am going to lose it.
I do not over eat, in fact I don’t eat anywhere near as much as I should for my height. There is no reason whatsoever for my recent weight gain.
Being overweight does not run in my family either. I recently tried stopping the
prescription Spironolactone, unfortunately my cystic acne returned immediately so I had to start taking it again. I would love to find a good alternative for this prescription.
I signed up just to give you my story. I'm 37 and I've had PCOS for over 10 years. I've always been on birth control for it. About 8 years ago I started breaking out on my chest and back really bad. My face wasn't to bad but it was extremely oily. I had been to many dermatologist who prescribed me all kinds of creams that didn't work. I finally found a dermatologist who told me we need to fix the problem from the inside out and I was put up 75mg of spironolactone. Over the years we have upped it to 150mgs. My skin looks great and I hardly have any break outs but I've suffered other ways.
I've always been skinny until August of 2018. I started gaining weight like crazy. August 2020 I'm now 30 lbs heavier and absolutely disgusted with myself. I went to 4 different endocrinologist who said all of my blood work was fine. I asked my dermatologist several times of spironolactone could make you gain weight and each time he assured me it wasn't the problem. Just like everyone else on this forum, my weight gain is in my stomach, butt, thighs and boobs. I recently went to a new gyno who put me on testosterone cream because mine was non existent because of the spironolactone. Some talk about sex drive, what is that lol. I felt better on the testosterone cream but still not happy and very over weight. Well I was recently hospitalized and didn't take spironolactone for 5 days. I noticed I wasn't as depressed and I actually had energy. My dad and husband noticed a difference in my attitude while in the hospital. I decided to take spironolactone once I was discharged and noticed my depression and lack of energy came back instantly. As of 2 days ago August 23rd, I quit it cold turkey and I feel so much better. I'm so scared I won't be able to loose this weight. I don't want to look like a model, I just want to fit back into my clothes and not hide from everyone because of my weight. I will continue with the testosterone cream and hopefully that will help me drop this excess of 30 lbs.
Hi there, I wish I have seen this post before I took this medicine. I am 44 and I had adult acne. My dermatologist unfortunately prescribed this medication to me. spironolactone 100 gm per day. He told me this is diuretic and it may even cause weight loss ! I took it and after a month I found I gained 10 lbs:((((((
This is a nightmare. I stopped it and I am trying to loose this weight now for 2 weeks. I see people here say it does not go away easily:((((
I am frustrated he did not tell me while all the ladies here suffered before me.
Any way. I will keep trying to loose this weight and I will never take hormone pills again.
Thanks for sharing this
Ok, I created an account just to answer this question and hopefully re assure some people. I was on spironolactone for just under a month and gained about 8 lbs. with my frame- it showed heavily. Mostly gaining in the thighs and stomach. My stomach was potruding and had never been that big before . I stopped a week ago and the weight is coming off and returning back to normal. It took some time but it’s getting there and dropping off again . So it did come off for me .
My gyno was skeptical of the weight gain too, I finally went to a doctor who practices functional medicine. She told me the spiro def affects your hormones. My progesterone levels were really low so she has me taking progesterone during my cycle. To make a long story short, once I started the progesterone, the weight came right off. I would rec getting your hormone levels checked. And spend the money to go to a doctor that looks at the whole picture.
