Diurex Review - Does This Diuretic Pill Work? Are side effects and lack of real weight-loss results deal breakers?

Editor's Review: 2.7 / 5.0
Diurex Review

I’m here to cut through the noise and get you to the bottom line on Diurex. We dug deep and came up with a comprehensive review, closely examining the ingredients, side effects, scientific studies and overall customer care. We additionally read tons of comments from all over the web. At this point we compacted and summarized to give you with the info you need.

EDITOR'S TIP: Substitute Diurex with a proven fat burner such as Leptigen for better results.

What You Need To Know

First off, Diurex is a series of supplements made by Alva-Amco Pharmacal Companies, Inc. The key ingredients are solubolized pamabrom and caffeine anhydrous. There are six different formula posted on the official website, which include Aquagels, MAX Water Caplets, Ultra, Water Pills, WaterCaps and Water Capsules. These are intended to “temporarily” reduce bloating and excess water weight. You have to read the directions on each label to find out how many to take.

We are uncertain when Diurex was first released, but the company itself dates back to 1904. You can buy the products in common drugstores, as well as online. You are encouraged to drink plenty of water daily while using the formula, but read on…

Side Effects – “Be Cautious?”

The first issue we realized with Diurex ingredients was that some dieter experienced side effects. “Whenever you choose a new supplement you need to take into consideration how it will make you feel,” says our Research Editor. “In this case, users have reported some irritating reactions.”

One customer commented, “Diurex causes diarrhea!”

“Doesn’t really work, just makes me nauseous,” said another user.

Scroll below for one of the best products we’ve seen over the last year.

Weight-Loss Results – “They’re Lacking”

Just so you are aware, Diurex pills do not burn off fat, suppress appetite or elevate metabolism, which means they will not help with long-term fat loss. One customer revealed, “Didn’t lose a single pound. These just make you pee a lot!”

Another user said, “No weight-loss from this! Don’t waste your money!”

According to our research, if there is some particular part of a supplement or weight-loss program that is very problematic or burdensome (lack or real results, side effects, a federal warning) the chances of long-term success are pretty low. This means if Diurex pills do cause ill feelings, this could be a serious dilemma.

The Science – “Is There Clinical Support?”

Actual science is not addressed on the company website for Diurex. However, this product does contain proven diuretics, so it should help remove excess water weight from the body. Then again, you should not expect it to help you lose excess body fat. After all, it does not contain proven fat burners or metabolism boosters. At DietSpotlight, we prefer to see published clinical studies that prove it works and that’s not something this supplement has to offer.

The Bottom Line – Does Diurex Work?

Hold up just one more minute so we can give you the final details on this one. We like that the ingredients in Diurex are offered online and it can help you with water retention, but we don’t feel comfortable recommending this to dieters because it is not clinically proven to boost weight-loss. We’re also concerned that it may interfere with some prescription medications.

If you need to see faster fat loss results and a slimmer figure, we encourage you to choose a diet supplement that is packed with clinically proven ingredients, does not cause harsh side effects and is supported by plenty of positive user feedback.

Among the best products we’ve seen in 2016 is one called Leptigen. This weight-loss pill contains four proven ingredients that have been shown in published scientific studies to boost metabolism and increase fat loss. We have not seen any talk of harmful side effects and user feedback around the web shows people are seeing significant results.

Also, the company that makes Leptigen is so confident in the formula they’re offering a Special Trial Offer, which is quite a good sign.

Diurex is a dietary supplement that is manufactured by Alva-Amco Pharmacal Companies, Inc., a company founded in 1904. It is marketed towards both women and men. This product aims to assist with discomforts by reducing "excess body water." There are actually five separate versions of Diurex for women; Diurex Aquagels, Diurex Water Capsules, Diurex Water Caplets, Diurex PMS and Diurex Water Pills. There do not appear to be any customer testimonials for this product. Diurex supplements can be purchased in most common drugstores and grocery stores.

The active ingredient found in Diurex supplements is Solubilized Pamabrom (diuretic that is stated to assist with bloating). Diurex endeavors to aid women with monthly swelling, bloating, water weight gain and puffiness due to their menstrual cycle. These diet supplements are stated to be free of aspirin and caffeine. Unfortunately there are no free trial samples of Diurex products available through the official website. Diurex is available without a prescription, but doesn't appear to be offered with a 100% money-back/satisfaction guarantee. There is no diet plan or fitness regimen recommended with Diurex supplements. The version of Diurex for men also aims to help minimize unwanted water weight. There doesn't appear to be any actual clinical research provided on the official website. This product sells for $25.74 for a 60 count of pills.

List of Ingredients

Solubilized Pamabrom, FD&C Blue #1, Gelatin, Glycerin, Hypromellose, Polyethylene Glycol, Povidone, Propylene Glycol, Purified Water, Sorbitol and Titanium Dioxide.

Product Features

This weight reduction supplement can be acquired in most typical grocery stores and drugstores. There is no clinical data offered on the website for Diurex supplements. Diurex sells for $25.74 and is available without a prescription.

Diurex is pitched rather differently than most weight reduction supplements. This product doesn't endeavor to suppress the user's appetite, burn calories, boost energy levels, assist the metabolism or burn away unwanted fat. Diurex mainly addresses water weight gain and the menstrual cycle of women. Therefore it's probably wise to investigate a number of other diet drugs before selecting a diuretic such as Diurex. In the end, it would be more reassuring to see some clinical data posted on the official website, along with some customer testimonials for Diurex and a 100% money-back guarantee.

    I started using diurex because I was bloated all the time period or not. I also gained about 10 pounds in 3 weeks and couldn’t figure out why. My mom suggested maybe I was retaining fluid and try a water pill. So I started taking it I went from 164 to 160 over night. I don’t feel as bloated, I’m only on day 2 but I feel good about taking this on a regular basis.

    I’m looking at the list of ingredients on Diurex Water pills and the only two stated (active) ingredients ARE caffeine and Magnesium Salicylate (NSAID)in contradiction to the description and ingredients listed above.

    I have gained nearly 30 pounds in fluid over the past month. Doc recommended trying this. I did and lost 10 pounds of water weight overnight. I did, however, experience significant chest pain and anxiety. It was crippling and made for a very long night. I bought the Caffeine Free Aquagels and they really did help me get rid of some of this fluid!

    I wonder if it would help get rid of next day drinker bloating. Any help would be apreciated

    this really works! lost 8lbs. of water weight in 2 days

    I tried this last month for my period bloating. And it seemed to work. I didn’t feel bloated. But I didn’t have any weight loss results to my satisfaction. Except for about 4 lbs that came back right after my period. You definitely need to eat before you take it. I took some before bed (no caffeine) and quickly discovered it made me feel nauseous. I took two tums to calm the feeling of wanting to get sick. If your trying to loose weight I would recommend diet, exercise, and some good appetite suppressant. Like Zyatonix. Free warning Zyatonix has unpleasant side affects too.

    How long will my pee stay green after taking Duirex water pills?



    Not long at all. Also, I lost 25 pounds in 8 months on Diurex; BUT I also cut my sodium intake down quite a bit by not eating any processed foods (like frozen dinners, pizzas, salty snacks, etc.), eating Greek yogurt with fresh fruit 7 drinking a lot of sparkling water constantly. Also, threw in walking in pool for 2-3 hours for 1st 2 months. Also, cut way down on sweets. I’m in my early 60’s & cut my size from 12 to size 6. It can be done. Plus no large meals after 8PM at nite (I stay up til midnite).

    i bought diurex max. cant find box. how often are you supposed to take them?


  • 14

    Your article stated, if I am correct, that, Diurex does NOT contain aspirin or CAFFEINE.
    I purchased Diurex Water Pills ( blue & pale green box from Walgreens) It clearly states Caffeine 50mg.
    Do the pills work?
    It says to take 2 pills every 4 hours, 8 total per day.
    Even with 8 pills… I am still very bloated.
    I’ll have to see what the Doctor prescribes.
    Online, Walgreens advertised the pills as 3.99, and the store charged 5.99.
    As of today…, unfortunately, (and, perhaps I might be suffering of some oddball situation…), but,
    I presently believe the product to be totally worthless.

    I also was unable to sleep until 3AM………
    I am not certain that this product is good for anyone.

    The Health Dept… should verify all these products… Why foolishly spend money on products that do not work, and, or, might detrimentally affect someone’s well being?



    Actually, there is a non-caffeine Diurux you can purchase also over the counter at any drug store. I’m concerned because my doctor recently said my kidney function showed up on blood tests as a bit low (I started taking Diurex – the blue one for 7 months this year due to taking prednisone & solu-medrol for MS (no kidney problems) & I drank a lot of water for 6 months). On the Diurex box it says that Diurex is FDA approved reader.



    Did you lose any of the swelling, taking this? I just got it because I have been on steroids for so long and I am tired of having a swollen face/ body.

    Dr. Dad

    Diurex works, but you need to buy the right one. I read labels. There is one who’s main ingredient is caffeine. I bought the one who’s main ingredient is Solubilized Pamabrom. Whether or not it works for hypertention I don’t know but my wife took it and she lost 8lbs in 2 days, however she was a little peeved about urinating so much.



    so which one should i get? the one with caffeine or solubilized pamabrom?!?!


  • 16

    Way overpriced and doesn’t work. Each pill has 50mg of caffeine, which is the main ingredient to lose water retention. I paid 6.99 for 42 of these pills, when I could have bought regular caffeine pills, 200mg each, 100 pills in a pack, for about 3 bucks. What a ripoff.


  • 17

    I have been using this for a bit now and I went to the doctors the first time and I lost 8 lbs the first time then when I went back 2 weeks later another 7 🙂

    Do not waste your money with Diurex, I took it for a week and saw no results. The only thing I noticed was that my urine was blue-ish, other than that nothing. It is such a waste of money.

    My dad and I both have been trying to lose weight forever! Neither of us are obese, just trying to shed acouple pounds. He lost 7 pounds using this pill in 4 days. After he told me that I bought it. I started using it roughly 5 days ago and I feel like I’m losing weight. I don’t weigh myself, but my jeans are fitting much better and my tummy doesnt look bloated. It makes you pee alot and yes the green is normal.. it tells you that on the box. I’m for sure going to continue using Diurex and would highly suggest it for anyone trying to shed afew. Of course the weight you lose can come back.. as with any diet… but take this pill, eat healthier and smaller portions, and drink water instead of soda an you’ll be good to go! 🙂

    does this help hypertension?

    can you take this product with a uti infection?


  • 22

    it takes about 3 doses to really start working for me,and yes, it does turn your urine blue-or green, depending lol. I have terrible bloating and it really helps. the only hard part is predicting when, so I can get the 3 dose head start.

    Lois Bocchicchio

    Have there been any reports of this medication causing urine to turn a bright green color?



    Yes… It’s right on the box and it’s caused by the blue food dye to make the caplets “pretty”! :D)

    I had to Google search Diurex for Men and found it tucked away in the website where you can’t see it. Since they don’t advertise it up front do they even make it? because I don’t see it anywhere in the stores.
