Update on an FDA warning about “natural alternatives” to treat impotence

Last year, the FDA warned consumers not to buy or use 7 supplements that were sold online to treat impotence and enhance sexual performance.

All but one are still marketed either by the same name or a different name. So, I’ve restated the warning with an update on the new names.

  • Zimaxx contains sildenafil (Viagra): Now called Zimaxx 2000.

The rest contain vardenafil, the active ingredient in Levitra, another prescription drug used to treat erectile dysfunction or impotence.

  • Libidus: Now called Maxidus
  • Neophase: Continues to be sold by that name
  • Nasutra: Now called Kama Sutra Rx
  • Vigor-25: Now called Rize 2
  • Actra-Rx: Now called Actra-Sx
  • 4Everon: Doesn’t appear to be sold anymore

You can’t be sure that the “new” products eliminated the Viagra or Levitra from their formualtions.

The problem is that consumers may not know that these ingredients can interact with medications and dangerously lower their blood pressure.
