Rex MD Ingredients: What's In Our Meds?

January 12, 2021

With the proliferation of sketchy online male enhancement drugs, it's no wonder we get questions about the ingredients in Rex MD's erectile dysfunction treatments. 

The answer is super simple though.

Rex MD medications are the same you might pick up form your local pharmacy, from Walmart, CVS, and any other pharmacy in the U.S. Rex MD's pharmacy partners use only branded and generic prescription medications approved by the U.S. Food and Drug Administration (FDA) with facilities subject to regular FDA inspections. 

We're just helping you get these effective medications quickly and easily from the comfort of home. 

What Are Rex MD's Ingredients?

If you're new to the world of erectile dysfunction medications you may be wondering how all of this works. (Don't worry, you're not alone: ED happens to over 50% of guys.) You know the name Viagra®, and probably Cialis® too. But what are they, and what are the ingredients in Rex MD treatments? 

When it comes to ED medication ingredients, it works like this.  

Viagra Ingredients and The -fils

All of the most popular and effective FDA-approved ED treatments are part of a class of medications known as PDE5 inhibitors (phosphodiesterase-5 inhibitors). You can think of phosphodiesterase-5 as the natural braking system on the erection process. By stopping (inhibiting) PDE5 in the body, these medications are removing that braking process, letting blood flow do its thing to make strong erections. Viagra® (sildenafil), Cialis® (tadalafil), Levitra® (vardenafil), and Stendra® (avanafil) are all PDE5 inhibitors (notice the -fil ending?). Viagra® was the first, approved by the FDA in 1998, with Levitra® then Cialis® entering the market about 5 years later and Stendra® more than 10 years later.

Rex MD helps guys access all of these treatments, though you can now also get generic versions of sildenafil, tadalafil, and vardenafil. These generic versions are much more popular because they're also much cheaper!

So what are the ingredients in Viagra® and sildenafil?

Let's use branded Viagra® to start. Viagra® is sildenafil citrate. That's what's "in" it, and that's what makes Viagra® do its magic. If you're buying branded Viagra® from Rex MD, that's exactly what you're getting: Pfizer's (the original manufacturer) tried and true original Viagra® recipe.

By comparison, generic products also contain the same active ingredient, sildenafil, but they're made with a slightly different recipe. That's because these generic drug manufacturers – like Teva, Mylan, Watson Labs, and many more – cannot copy the original Viagra® formula, but they can make their own version with sildenafil that acts the same way in the body as the original. 

That's the premise behind all generic drugs: a different recipe that performs the same way as the original branded version in the human body. This is called bioequivalence.

Generic sildenafil products are bioequivalent to the original Viagra®.

Generic tadalafil products are bioequivalent to the original Cialis®. 

The same with Levitra® and generic vardenafil. 

Each drug manufacturer must prove equivalence to the FDA before their medication can be approved for use in the U.S. 

What's in Rex MD Viagra® and Generic Sildenafil?

All that to say, Rex MD's men's health treatments are FDA-approved and come from these FDA-inspected companies and manufacturing facilities. We don't make medications, we just help guys access great, proven solutions at great prices and from the comfort of home.
