Don't be fooled by counterfeit VIAGRA.

Don't be fooled by counterfeit VIAGRA.

Counterfeits aren’t just a cheap knock-off of a proven product; they’re illegal, potentially harmful fakes. It’s hard to tell where or how they were made—or even what’s inside them.

VIAGRA is one of the most counterfeited drugs in the world.

In March 2011, Pfizer Global Security studied the search results for the term "buy VIAGRA" to see how many online pharmacies were selling counterfeit VIAGRA. 

The study was conducted using the top 2 search engines over a 5-day period. During this time, 22 unique sites consistently appeared among the top search results claiming to sell VIAGRA manufactured by Pfizer. Pfizer Global Security then ordered VIAGRA from these sites and tested the chemical composition of the pills.

Warning: Counterfeit medications can be dangerous.

What we found in counterfeit VIAGRA

  • Blue printer ink
  • Amphetamines, also known as “speed”
  • Metronidazole, a powerful antibiotic that could cause an allergic reaction, diarrhea, or vomiting
  • Too much active ingredient (or not enough), which may cause you harm
  • Binding agents, such as drywall, that prevent the tablet from breaking down in your system

What we found in other counterfeit medications

  • Toxic ingredients, such as boric acid, floor wax, brick dust, rat poison, and road paint
  • Ingredients that can have dangerous interactions with other medications you may be taking
  • A completely different medication with potentially harmful side effects


Learn how to safely buy online.

Make sure that when you buy VIAGRA online, you get real VIAGRA. Many of the sites that claim to sell VIAGRA online are actually selling potentially
dangerous counterfeits.

Watch: Online pharmacy scams

Follow these steps:

  • 1 Make sure the website requires a valid prescription. It’s illegal to sell VIAGRA without a prescription from a qualified healthcare professional.
  • 2 Make sure you see a U.S. address and phone number. This can help you make sure the website is not selling unregulated medication from overseas.
  • 3 VIAGRA only comes in 3 doses. 25 mg, 50 mg, and 100 mg. VIAGRA is a tablet. Any other form, like “fast-dissolving,” “extra-strength,” “soft-tab,” or “VIAGRA for Women” is not FDA-approved.
  • 4 Look for Verified Internet Pharmacy Practice Sites® (VIPPS®). A VIPPS® accreditation ensures the website you are purchasing from is secure and reliable.
