Redotex Review: Can You Buy Redotex Online? Side Effects & More

Expert opinion:

Not Recommended


Manufactured by the Mexican pharmaceutical company Productos Medix S.A. de C.V., Redotex is a pill marketed as a weight loss agent. These “Mexican diet pills” cannot be sold legally in the USA—as far back as 1987, the FDA had issued warnings about the safety of Redotex. Even so, it is still used by consumers in the USA who have purchased it online or in person when travelling to Mexico.1

So, what is Redotex, exactly? Available in capsule form, we can think of Redotex as a “rainbow pill”, a type of weight loss supplement that includes multiple pharmaceutical agents. It’s common to see amphetamines combined with benzodiazepines in these types of pills, providing the user with a stimulant effect from the amphetamine and countering it with the tranquilizing effect of benzodiazepines or other depressants.2

Because of the safety concerns surrounding this diet pill, it is important to for consumers to understand the ingredients in the pill and the effects they may have. In this article, we answer common questions about this weight loss aid, including a review of its ingredients, efficacy, side effects, and availability for purchase.

Redotex reviews – why is Redotex NF banned?
Redotex ingredients and side effects

The depressant used in Redotex is diazepam, which commonly known by its commercial name, Valium.

Redotex Ingredients

Redotex contains several pharmaceutical agents, including stimulants and depressants. The stimulants in Redotex diet pills are atropine and norpseudoephedrine, which are combined with diazepam, a depressant commonly known under the commercial name Valium. Other ingredients include aloin (a derivative of aloe vera) and tri-iodothyronine (a thyroid hormone).2,4,6,7

Tri-iodothyronine: 75 mcg – Also called T3, this is a thyroid hormone that is naturally present in the body. It affects a myriad of biological processes in the body, including metabolism. Researchers have found that having too little of certain thyroid hormones (a condition called hypothyroidism) can result in weight gain. Although the mechanism behind T3 and body weight reduction is not fully understood, thyroid hormones in general are used as a treatment for obesity.4

Redotex uses a combination of stimulants, laxatives, and depressants to effect weight loss. The depressant diazepam does not seem to have any weight loss merits of its own, but is used to counter the effects of the stimulant.

Nor-pseudoephedrine: 50 mcg – This is a stimulant belonging to the amphetamine family. Various types of ephedrine are used in weight loss and athletic performance enhancement drugs.6 Studies measuring the weight loss effect of ephedrine have found that it promotes modest weight loss and is an effective adjunct treatment for obesity, at least in the short term.5,6

Atropine Sulfate: 0.36mg – This sulfate is derived from the Atropa belladonna plant and when consumed, may induce tachycardia, inhibit secretions (such as the secretion of saliva), and relax smooth muscles.9 There are no known studies investigating the relationship between atropine and weight loss.

Alion: 16.2 mg – Derived from the Aloe vera plant, alion (and other Aloe-derived compounds) are known to produce laxative effects. Aloe has long been used in traditional medicine as a natural laxative to treat constipation. Aloe vera latex is regulated by the FDA as a laxative.7

Diazepam: 8 mg – This drug belongs to a family called Benzodiazepines. One of the most widely prescribed pharmaceuticals in the U.S., Diazepam (also known under the commercial name Valium) is used as an anticonvulsant and for treating anxiety, inducing sedation and muscle relaxation.9 It is common for “rainbow diet pills” like Redotex to include a depressant such as diazepam to counter the effects of the stimulants included in the formula.2

Redotex Side Effects

The side effects of Redotex were documented in a 2015 study that asked Redotex users to report any adverse effects they experienced while taking the Mexican weight loss pills. Reported side effects included headache, dizziness, constipation, anxiety, nausea, irritability, drowsiness, nervousness, dry mouth, hypertension, insomnia, fatigue, asthenia, tachycardia, and abdominal pain. One notable fact about these reports is that approximately 40% of users experiencing adverse effects experienced 3 or more of the negative side effects listed above.3

Concerns about Redotex were raised by the FDA as early as 1987. It is currently an illegal substance in the US, and most commonly purchased in Mexico.

Because Redotex contains several pharmaceutical agents, it’s likely that it could interact with other medications, with the possibility of negative outcomes. In the study mentioned above, many of the participants who reported negative side effects were also taking additional anti-obesity drugs, hepatoprotective drugs, anti-hypertensive drugs, contraceptives, and hypoglycemic drugs.3

Do Redotex Pills Really Work?

Redotex results have not been examined in any known clinical trials. It is true that these illegal diet pills use a combination of agents that have resulted in weight loss individually in other contexts. Ephedrine has been observed to result in modest weight loss, at least in the short term.6 Likewise, laxatives (such as the aloin included in the formula) are often used by people who want to lose weight because of the laxatives’ ability to flush out the digestive tract. While it is likely that Redotex pills will help with weight loss, it is still an illegal product in the US and prone to many side effects.

Why Is Redotex NF Banned?

While the FDA banned the drug before there were any negative reports in medical literature, at least one recent study (conducted in 2015) found that using the diet pills resulted in a variety of adverse outcomes, and there are case studies of the pill’s harmful effects.1,3 In general, health authorities are wary of this type of “rainbow pill”  due to the unknown effects of the individual ingredients and inappropriate dosages, the risk of consuming poorly manufactured products, and the lack of medical literature proving that the product is safe for consumption.2

Redotex Reviews      

What are users saying about these mysterious diet pills from Mexico? Like many diet pills, results are varied and reviews are mixed. Some who have taken the Redotex diet pill appear to have lost a significant amount of weight, with testimonials from users reporting weight loss between 1-5 pounds per week. There are also users who have reported no weight loss at all.3

Where Is Redotex For Sale?

It’s difficult to buy Redotex because these Productos Medix pills are not available in many countries outside of Mexico. To find Redotex pills for sale in person, buyers must travel to Mexico and consult with a doctor.

Can You Buy Redotex Online?

There are sites that have Redotex for sale online. However, even when you order Redotex online, your purchase is still subject to investigation by U.S. customs—it’s possible that the product could be confiscated and that U.S. customs would impose a large fine for the undeclared medication. Because it is not regulated in the U.S., it’s also difficult to tell whether or not you’re buying legitimate Redotex or a look-alike product.
