What are Diurex Water Pills?

First off, Diurex Water Pills is a diuretic containing caffeine and magnesium salicylate. [1] [2] The recommended dose is four to six capsules per day, not to exceed eight pills, which supposedly results in water weight-loss. One of the benefits is that the supplement is available in many stores.

There is no information as to when Alvo-Amco introduced Diurex Water Pills, but the company started operations in 1904. You can shop for the supplement at local retailers and trusted online stores. We do like that the business is more than 100 years old and the favorable BBB rating, but read on…

Ineffectiveness – “Diurex Water Pills Doesn’t Work?”

The first concern we have with Diurex Water Pills ingredients is ineffectiveness. “When dieters choose a weight-loss supplement they want something that works long-term,” offers our Research Editor. “With Diurex Water Pills the effect is short-term or not at all.”

“Didn’t work for me…was looking to lose pms water weight and I didn’t see any difference,” commented a user.

Some found that Diurex Water Pills actually produced results. “Bloating went away in a few days,” reported a customer.

Side Effects – “A Problem for Some”

According to numerous customer comments Diurex Water Pills side effects are a bit taxing. “Made me sick to my stomach. Didn’t help the bloating matter of fact made it worse. I took it for one day and had to discontinue use because I felt so horrible,” said a dieter [3]

“I had a lot of unpleasant side effects while taking these. Keep in mind I drank plenty of water, at least 8 glasses. Nausea and diarrhea, which would start about 1 hour after taking. I also had a splitting head ache after taking each of my doses that day,” reports a consumer.

We found that some users noticed positive side effects. “No headache, nausea or bloating. Works pretty good,” reported a user. [4]

“It boosted in my energy levels, no side effects” said another.

Our research shows that if any part of a supplement is problematic, like not producing results, long-term success is limited. If Diurex Water Pills don’t work, there’s an issue. [5]

The Science – “Any Validity?”

The official website states that Diurex Water Pills are backed by science. There’s research supporting the benefits of caffeine and magnesium salicylate, but there’s no direct connection between this formula and weight-loss. At DietSpotlight, finding concrete science supporting the claims is critical. If there’s none, we have concerns.

What Users Are Saying

“These water pills have worked great for me for years. I travel internationally, am overweight, and tend to swell a bit in warm climates. These pills provide just enough relief without causing me to feel wired or too dehydrated. Gentle and effective.”

“I have used the diurex a couple of times and they seem to help the fluid distribute throughout the body and reduce the edema in my legs so I will keep using them.”

“These were not expired but I got sick from them and threw up.”

The Bottom Line – Do Diurex Water Pills Work?

So, here is the final take Diurex Water Pills. We like the length of time the company has been in business and that we found some positive customer comments, but we have concerns about this one because there are no clinical studies supporting the weight-loss claims. We’re also a bit skeptical due to customer comments about lack of results and negative side effects.

If you’d like to slim down, we suggest going with a product offering proven effectiveness without side effects. A good price and supportive customer service team are also important.

Among the best products we’ve seen this year is one called Burn HD. The formula contains a four-ingredient proprietary blend, which has been shown in published studies to help ignite fat loss and enhance metabolism. There’s no one talking about negative side effects and the comments online show people seeing excellent results.

Also, the company that makes Burn HD shows confidence in the product by offering a 2-Week Sample, a good decision.

This is a common stimulant that’s found in coffee, energy drinks, tea, chocolate and various over-the-counter diet pills. It comes from natural sources like kola nut, guarana plants, coffee seeds and tea leaves. [1]

What is it Supposed to Do?

Typically caffeine is used in diet pills and energy supplements to help reduce fatigue, boost metabolism, elevate energy levels and improve focus/concentration.

Clinical Research

“A review published in 2011 in Obesity Reviews examined six studies and found that caffeine supplementation significantly increases your body’s energy expenditure over a period of 24 hours. Caffeine often causes a boost in energy and decreases in perceived physical exertion, which may be one reason your body burns extra calories when you consume caffeine.”

Magnesium Salicylate (NSAID)

Magnesium salicylate is considered an NSAID or nonsteroidal anti-inflammatory drug. It’s found in some medications and over-the-counter supplements.

What is it Supposed to Do?

Magnesium salicylate is supposed to help reduce inflammation, pain and swelling. It’s sometimes used to treat conditions such as arthritis.

Clinical Research

According to WebMD, “Magnesium salicylate is used to relieve pain from various conditions. It also reduces pain, swelling, and joint stiffness from arthritis. This medication is known as a nonsteroidal anti-inflammatory drug.”

Acacia Gum

Also called gum Arabic, this is a type of dietary fiber that is made from Acacia tree sap or gum. It’s used in some medicine to treat high cholesterol levels and obesity. [2]

What is it Supposed to Do?

Acacia gum is a fiber that may help you feel full. Aside from reducing appetite, this ingredient might cause more regular bowel movements.

Clinical Research

“In 2012, the Nutrition Journal published a study on the effects of gum Arabic, which is derived from acacia powder, on body mass index and body fat percentages in healthy women. Researchers found that participants who consumed 30 grams of gum Arabic every day for six weeks experienced lower body weight, as evidenced by a lower body mass index count. There was also a reduction of over 2 percent of body fat at the end of the study for those who consumed the gum Arabic supplement.”

Diurex Water Pills: What You Should Know

Many dieters will do almost anything to shed some excess pounds. Hence the massive assortment of diet pills, weight loss supplements, and fitness equipment available today. There are even weight loss products that address water weight. One of these supplement formulas is Diurex Water Pills. You can find this product through common drugstores like Walgreens, as well as several online stores. It sells for around $5.99, and is described as prompt and effective. However, before you run out and buy Diurex Water Pills, we will give you the rundown on this formula, and how it actually works.

List of Ingredients in Diurex Water Pills


  • Caffeine 50mg
  • Magnesium Salicylate
  • Acacia

Product Features

Diurex Water Pills are supposed to help you by relieving water weight gain. This formula also assists with fatigue, bloating, abdominal swelling, and minor aches and pains. It can be taken in a dose of two pills every four to six hours. However, this supplement should be taken with six to eight glasses of water each day. Basically, some men and women take this formula to get rid of excess body water. Just to be clear, Diurex Water Pills are not suitable for people under the age of 18. Furthermore, eight pills should not be exceeded in one day.

The primary ingredient used in Diurex Water Pills is Caffeine. This is a stimulant and diuretic. It helps draw water from the body, which may result in some temporary weight reduction. However, there are no key ingredients used in Diurex Water Pills to suppress hunger or burn off fat. Furthermore, there is no healthy meal plan or fitness regimen recommended with this supplement. This product can lead to side effects like facial swelling, dehydration, shock, headaches, insomnia, hives, and wheezing.

Advantages of Diurex Water Pills

  • This product is readily available in common drugstores.
  • It is encouraged to consume a lot of water with Diurex Water Pills.

Disadvantages of Diurex Water Pills

  • There are a number of side effects that apply to this pill.
  • No proven weight loss ingredients are used in Diurex Water Pills.
  • There is no fitness regimen or diet plan encouraged with this product.
  • You can get the same effect from drinking coffee.


Like other caffeine-based supplements, we do not recommend Diurex Water Pills. You must understand that these products only draw water weight from your body. They do not assist with fat loss or long-term weight reduction. Therefore supplements like Diurex Water Pills are not ideal for shedding unwanted body weight. You should also consider the amount of caffeine used in this supplement. Unfortunately it can lead to side effects like insomnia, dizziness, rapid heartbeat, irritability, and dehydration. It is wise to choose a weight loss product with proven ingredients.

5 Diurex Water Pills Reviews

  • Andrew (Verified User)

    I am a truck driver. It is difficult to not only eat correctly, but to also find time to exercise. I initially started taking one bottle of Diurex. Didn’t really notice much weight loss–but I did. However, the caffeine kept me alert, and didn’t make me crash. Towards the end of the bottle I had slowed up daily use for no apparent reason. I had managed to start waking up a few hours before my shift in order to speed walk. I started out with two miles, and I am now to four! I drink half my bodyweight in ounces. But when I noticed that instead of my weight decreasing it was increasing dramatically! So I return to finish the remainder of my first bottle. Sure enough, within 3 days, I’ve lost 8 lb of water weight! However, the negative side effect I had was arthritis pain in my left hand. Now, I am pre diagnosed with arthritis, however I have not had an episode in several months until today.

  • Aleshia

    I’ve been taking the pills for a few days. I got them cause my feet started swelling a little while my cycle was on. The first few hours after taking the pills the swelling was gone. It made me pee a lot. That’s what I wanted. It flushed me out well… Day 2. I took two pills and an hour later I got very sick. Threw up all day. I had hot flashes all day long. After today I won’t be taking any more.

    • Maribel (Editor)

      Hi Aleshia. Thanks for keeping us informed about your experience. So sorry you had these side-effects and the product didn’t work for you. Might want to take a look at Dietspotlight Burn? It delivers powerful results with safe ingredients backed by science. Hope this helps.

  • Sam

    I have used Diurex on and off for years. They work for me. Having high bp, you can have swelling in your limbs. I have used them to reduce or eliminate the swelling along with cleaning up my diet. They definitely help if I get off track.

    Latricia (Verified User)

    These pills have worked me in the past and still work now. I started take them about two years ago for my cramps and bloating every month. But have notice that it is great for weight loss. I lost 3-4 pounds nothing big.
