I just started taking losartan. So far I don't think I have any side affects except made headaches from day one. I have other health problems and I don't want to gain weight. I was just wondering if losartan can cause weight gain?

Weight gain is not listed as a possible side effect of Losartan.

Yes! Losartan (cozaar) does cause weight gain I have gain more than 150lbs since I started taking it and my Dr. Just figured this out and had switched me to another high blood pressure medicine. Since then I have lost 40lbs of that weight so far and it's only been 3 months. I know it seems impossible but this is absolutely true story.

So glad I found this forum! I started Losartan Potassium about 9 months ago. Despite exercising 4-5 times per week and 95% watching my diet, I have been losing and gaining the same 10 pounds. Very frustrating! I always felt that Losartan contributed to my inability to lose weight.
I also believe that Losartan is to blame for my chronic sinus infection. I rarely had any major nasal issues before taking this drug. Since taking it. I've had a constant post-nasal drip. I'm sick of hearing that it is allergies and change in the weather. Nonsense. I never had these problems BEFORE Losartan. I've been an ENT and an allergist, and they just throw Nasonex and Azelastine at me. I'm sick of spraying stuff up my nose. Who wants to live like that forever?
Since I have stopped taking Losartan (and all the nose sprays), my sinuses and post-nasal drip have cleared up considerably. I'm also no longer bloated and tired from the Losartan. Now I'm hoping the weight will start coming off again.
Sick of tired of these drugs!

i have been taking losartan 50mg for almost 3 years. i have gained 118lbs. my dr. said that it shouldn't cause weight gain. i think he was just reading the side effects list the drug company posted. i'm seeing him in 10 days and i will get him to change my prescription. any suggestions for a new bp drug that will allow me to drop this weight?

I lead a very active lifestyle and train for triathlons 8 months out of the year. My typical week consists of 8-12 training sessions; running swimming and biking.
Ever since I started taking losartan 7 months ago my weight is up 30lbs... this is with a strict plant based vegan diet and continual strenuous workouts.
I can find no other reason for my weight gain. I'm thankful I found this site and for all of you because I have been frustrated beyond belief not understanding what has caused my weight gain.
If you hAve found successful alternatives tolosartan i would love to know. Thanks

I have started Losartan 100mg I asked my doctor why such a high dose? His response was that is what is recommended for a woman 145 lbs 5'6"... I am a spin instructor and work out over 4+ days per week... I have GAINED 20 pounds since August 2015! I have an appointment with my doctor today to replace this medication! Has anyone else experienced this? Please let me know your age and weight?

I agree totally with the responses i read on here. I was floating around 240-250 before taking Losartan and in a few years i got up to 289. A difference of 40-50 lbs. I am 6'2" and a naturally big guy but this drug made me bloated, gave me terrible heart burn and acid reflux, and constant sinus problems and chest congestion. Plus i was tired and my heart would skip beats, i felt like i was gonna pass out at times for no reason , dizziness. I am on Metoprolol 25 mgs and i feel 100% normal and calm on this medication. My B.P. was 145/95 on Cozaar and now its around 125/85 on Metoprolol. This crap was posion for me! I told my doctor to please annotate this as a no-no for me in my charts.

My doctor prescribed this medicine for me almost 6 months ago. Since then I have had numerous sinus infections, bad headaches, and steady weight gain. I am a vegetarian and I watch what I eat, but I have gained 15 lbs. since starting the med. And no matter what I've done to drop the pounds, including 10 days of juicing to detox, I have continued to gain weight.
Tonight I realized that all of these problems started with this medication, and so I started my online search for answers when I came across this website. Thanks to each of you for sharing your stories about Losartan!
One of the major culprits of high blood pressure is being overweight. To think that this med is contributing to the problem, and others, is extremely alarming. But it is exactly what has been happening in my case.
Like many of you, I am calling my doctor first thing in the mornings to come off Losartan. I am so relieved to know that Losartan is the cause of my rapid weight gain, sinus problems, headaches. Thanks again for your help!!
