HOUSTON, TX (CNN) - If you have been to just about any gas station, you may have noticed those pills behind the counter promising energy, dietary results and sexual performance.
Many who have tried these sexual performance pills say they work but that’s because some of them contain Viagra, which is not only illegal, it's also dangerous.
Attorney Robert Tauler says they have had several people who have suffered serious emergency surgeries after taking these pills.
Tauler’s law firm has filed a suit against 15 shell convenience stores in the area.
Attorneys claim the pills contain the main ingredient in Viagra, which is only legally available by prescription.
The FDA does not regulate gas station pills because they are considered dietary supplements, but officials are advising consumers not to buy Rhino Brand pills.
Officials say the pills are manufactured overseas and are sold under several different names.
Tauler says the companies change the names because they know they can beat federal law enforcement for now.
Dr. Erik Antonsen of Baylor College of Medicine says there’s no way for customers to know what is inside the pills and if you’re having issues, you should talk to your physician about it.
Dr. Antonsen goes on to say that these issues must be diagnosed by a licensed medical professional before taking any medications.
