Coumadin linked to weight gain

Yes, im definitely experiencing this. I have had weight loss surgery because I have multiple sclerosis. It's very frustrating for me right now. Adding one more medication that's making me gain weight when I can't do a hard workout to counteract it. What have you found to help with this side effect?

I, like many others, am very happy and perplexed to learn this. I thought it was the Celebrex I was taking. But I've gained 25 lbs in a year while taking 7.5mgs a day. Has anyone found that switching to xarelto has changed this? I'd love to know.

I don't know why Doctors will NOT acknowledge what we tell them is happening to us with this drug.  My problems started with terrible joint and muscle pain and now the Fatigue and weight gain has set in and I was told by my doctor and my specialist that "Coumadin does not cause those things".  I went to another site and there were many people complaining of the same things.  I even started juicing again to try to counter everything I have been experiencing and even with juicing, I haven't lost a pound! They need to do another study and include all of the people already on this Drug and ask us what's going on!  I would tell them I am in pain, fatigued beyond belief and have gained weight. I have been on the medication for 5 months and have gained 10 lbs and it makes the pain in my knees worse.

OMG you have no idea I have been on coumadin for 6 years and have put on weight every month! I do not each much and feel so bloated. I am embarrised to tell you how much I gained it is over 80lbs

you're making a lot of sense buddy-seems the build up round tum might be blood/water? But theres got to be an answer,one that our so called doctors cant be bothered to care about. We have to be our own detectives I think. Check out what Gary Moller's got to say on his blog,you may find it interesting,he's no admirer of big pharma. Funny thing is I've quit warfarin because of bloating,weight gain,but can't get rid of the spare tyre. Your theory makes a lot of sense,i'm using vit e/flax seed oil as blood thinner.But it seems any blood thinner has the tyre effect.
cheers,good luck

Yes im on warfarin and iv'e gain 25 pounds in a month. dr's say it isn't the warfarin (Coumadin).

I have been on warfarin (coumadin) for a little over a month and iv'e gained 23 pounds already

I too have been tested and the TSH came back normal (highest I saw was 2.8 - i have slowly put on 20 lbs in the last few years on warafin- I am very athletic and know how to eat right and found I even still gained while on a 1200 cal diet- I was told that's not normal by my personal trainer- even worse as the fat % calculations changed so fast in a matter of a week that they even told me something was wrong but drs will not listen- just eat right for a year- ??? I do eat right- I do work out right, something is not right even their own nutritionists have said i was doing everything right and yet and they wont believe me- I have even gone to extreme down to 600 cal a day and dropped 2 lbs- then while stil at 600 cal a day lost nothing and continued to gain.. its frustrating

I am seventy four years old have been using cumaden for around  seven years who has never before been over weight in my life. On Cumaden I have gone from 165lbs. to 186lbs. I am health concious and exercise and cannot seem to loose the extra pounds. I sensed this weight gain might be  related to the drug, and from all the complaints I see on this site, I'm begining to believe it.  Too bad the drug companies don't tell you about the weight gain side effect, which is in itsself, contradictory to good cardiovascular health. On one hand you have your cardiologist nailing you for weight gain while on the other hand he is dispensing you the substance that is causing the problem. Its like being caught between a rock and a hard place ! There's got to be a better and safer solution to blood thinners. HELP!

I have been on coumadiin for 15 months and have gained 13 pounds. I am eating less, am just as active and hate it. I had a DVT from Tamoxifen. Because blood work showed up that I had Factor 5 from ONE side of my family, my hematologist said I have to be on coumadin for 2 years. I have no trouble keeping my reading between 2 an 3, but bruise easily, am tired and can't wait to get off this drug.

I have been on Coumadin since 2010 due to DVT in both legs and also in my lungs. I also have Factor 5 Deficiency from /through my mothers side of the family unfound until after I was on the Coumadin over 2 years. I treat at Veterans Hospitals, currently in the Long Beach, California one, moved from prior one due to inconsistent treatment/poor trreatment issues. - NOTE: In the first year I was on Coumadin (which 2004-2006 due to a brown recluse spider bite and resulting blood clot in leg due to sustained inability to walk/long seating weakness. Lack of mobility (due to severe pain), I noted WEIGHT GAIN of 24 lbs in that period. They stopped the Coumadin in June 2006. I began losing weight with a few weeks, eventually losing 20 lbs. and got my energy back...in March 2010 after again sedenary living due to (at the time unknown, later found- gas leaks in the rental house I was in in Los Angeles) I was Diagnosed again with blood clots- this time massively in both lungs -and my right leg DVT. Hospitalized for that in the VA West Los Angeles Med center for 3.5 weeks. Compromised my breathing, restored mostly with resulting asthma now ongoing plus continual use of Coumadin since then. Within 6 weeks of use of Coumadin (5 mg daily on average) -I again noticed significant weight gain irrespective of increased activity or not and again, as before, plus some increase in tiredness. It is now 2015 (January) and I have gained significant weight since March 2010- appreoiximately 100 pounds. My Dr's insist it is not due to the Coumadin, so i copied this website address and information to direct them here to read and find out for themselves THEY ARE WRONG- Coumadin DOES-in a certain percentage of users- CAUSE WEIGHT GAIN of significant amounts in a certain portion of the population taking it. and Note: multiple users saying increased lifestyle changes didn;t affect much in reducing the gain. I wanted to post this here to advise those who read it- that you may experience significant gain in weight if you are on Coumadin for a long time. Due to my Factor 5 deficiency - per my Dr's- it is unssafe for me to be changed to one of the other blood thinners now being tested/sold to replace Coumadin.

I have been on the generic version of Coumadin(Warfarin) since 2008(10-12mg/day) with no weight gain. I am active, weight training 3-4 days/week and hiking at least once per week. I had an aortic valve replacement with a mechanical valve in July 2008. I will be on Warfarin for life. My weight before surgery was 185 and is 185-190 today. I am very aware of my body composition because I was a bodybuilder in my twenties(60 now). My diet is consistent and balanced with larger amounts of protein(100 + grams/day). If someone taking Warfarin is taking SSRI drugs for depression or other drugs, they may want to research the weight gain side affects of these drugs. This is the first time I have heard people blame Coumadin for weight gain. Look at your activity level. Are you as active. Doctors can scare people into a less active lifestyle citing the dangers of an accident with physical activity which may cause a hemorrage or a fatal bleed. I haven't personally had a weight gain problem with Warfarin and if I gain weight, I know I have been consuming mire calories then my body requires. I don't doubt the posters personal experience, I am just sharing mine. David

You are so right, I was told it was not the coumadin, but since I have been on it in the last 6 mos. I have gained about 7 pounds. It does make you gain weight.

Hi i have a DVT on my left leg for the last 7years.  I am on a 1500 calorie diet and i am on warfarin for 7years even doctors says that you should not being getting weight on warfarin it seems that i have gained a lot of weight on my belly so it does i was 140 and now i am struggling with loosing this weight i should not being getting weight but i am and is horrible i should be loosing with my diet.  I alway said that is the warfarin.  Every month i gain weight for no reason is not my eating habits i had change my whole diet since i started the 1500 carbohydrates and yesterday i was 196 and today i am 198 two pounds in one day makes no sense

I've been on Coumadin for 8yrs now. I have gained a ridiculous amount of weight. I eat very well & exercise 3/4 days a week. I DEFINATELY think the weight gain is due to the Coumadin:/
