If you’ve ever checked out the male enhancement products sold in gas stations, convenience stores and elsewhere, you may have come across a variety of pills sold under the brand name “Rhino.”
Rhino pills, as they’re known, claim to offer the usual benefits common to over-the-counter sex supplements: harder erections, extra stamina and better sex overall.
Like with almost all other male enhancement products, there’s no scientific evidence to back up these claims.
Furthermore, investigations have found that many Rhino brand products contain undeclared and potentially dangerous ingredients.
Below, we’ve explained what Rhino pills are, how they typically claim to work and the many risks that are associated with these products.
Rhino is a common brand of male sexual enhancement products. Rhino pills are typically sold in gas stations, drug stores and online.
Supplements sold under the Rhino brand have a variety of names, including:
Most Rhino pills come in similar packaging, with a distinctive design that’s dominated by a large, holographic rhino.
Some appear to use similar packaging with alternative brand names, such as “Jet Black™,” “Jet Blue™” and others.
Rhino male enhancement products are marketed as offering numerous sexual performance and health benefits, such as:
Rhino products aren’t approved by the FDA, nor do they require a prescription. Because they’re cheap, widely available and don’t require a visit to the doctor’s office, they’re often perceived as an over-the-counter alternative to drugs like sildenafil (the active ingredient in Viagra®).
Like many dietary supplements promoted as male sex aids, Rhino pills as marketed as using a blend of herbal ingredients that naturally improves sexual performance.
For example, the supplement label for Mega Rhino 82000 lists zinc gluconate, horny goat weed (epimedium), white willow bark, black pepper and Rauvolfia serpentina as active ingredients.
Because there are so many different products sold under the Rhino brand name, it’s difficult to know precisely what goes into each capsule.
However, several investigations by the FDA have found that many Rhino pills contain unlabeled ingredients, including active ingredients from prescription drugs.
In one lab test, the FDA found that the product Rhino 8 Platinum 8000 contained the ingredients sildenafil, N-desmethylsibutramine, phenolphthalein and diclofenac.
Sildenafil is the active ingredient in Viagra. It’s a prescription ED medication that’s only available for people who have been diagnosed with erectile dysfunction by a licensed healthcare provider.
N-desmethylsibutramine is an ingredient that’s structurally similar to sibutramine — a controlled substance that was withdrawn from the market in 2010 due to concerns about its safety. It was previously used as a weight loss medication.
Overall, the FDA has identified more than 25 products sold under the “Rhino” brand name that contain undeclared ingredients, often prescription medications.
In response to these issues, the FDA has warned customers not to purchase or use any Rhino enhancement pills or other products.
Rhino pills and other sexual enhancement products that use unlabeled ingredients have major safety risks, including the risk of causing drug interactions.
Many of these products contain sildenafil, tadalafil and other ingredients that are typically used in prescription medications for ED.
These active drug ingredients can interact with other medications and cause potentially serious complications.
For example, sildenafil can interact with nitrates and other medications used to treat high blood pressure, angina and other cardiovascular health issues. This can cause a sudden, potentially fatal drop in blood pressure.
Because Rhino pills and other sexual enhancement capsules aren’t FDA-approved prescription drugs, they aren’t subject to the same strict testing and licensing rules.
These supplements may be produced in unsafe or unsanitary environments. The hidden drugs used in these products may not be measured accurately, meaning some supplements may use an unsafe amount of these unlabeled active ingredients.
Because of these risks, using Rhino pills or other dietary supplements that claim to treat ED or enhance sexual performance is not recommended.
The FDA’s guide to tainted sexual enhancement products provides more information on dietary supplements that contain hidden, potentially harmful active ingredients.
While Rhino pills and other over-the-counter sex pills aren’t recommended, there are safe and effective options available for treating ED and improving sexual performance.
When used before sex, they make it easier to get and maintain an erection while you’re sexually aroused.
Safe and effective treatments are also available for other sexual performance issues, such as premature ejaculation (PE).
Before using any sexual enhancement products, supplements or medications, it’s important to consult your healthcare practitioner.
Like other male enhancement and penis enlargement pills, the Rhino pills available online and in gas stations aren’t recommended.
Not only are these pills of questionable efficacy — many contain unlabeled or unapproved drugs that could put your health at risk.
If you’re worried about erectile dysfunction or premature ejaculation, the best option is to talk to your healthcare provider or look into FDA-approved ED treatments.
Unlike Rhino pills, these medications contain exactly what they say on the label, meaning you’ll be able to treat ED, PE and other sexual performance issues with confidence.
