Viagra Sublingual: Does an Under-the-Tongue Version Exist?

Sildenafil, the generic version of Viagra, can be formulated for release under the tongue (sublingual), but these products are not available in the U.S. Studies suggest that sublingual sildenafil can lead to faster results with a lower dose. While sublingual sildenafil is not available in the U.S., another sublingual ED medication called Staxyn is available. Both Viagra and Staxyn are available from eDrugstore.com.

Pfizer’s blockbuster erectile dysfunction (ED) drug Viagra is a tablet available in dosages of 25 mg, 50 mg, and 100 mg, and is taken by swallowing the tablet with water.

Some manufacturers of sildenafil (Viagra’s active ingredient) in other countries have created sublingual forms of the drug. “Sublingual” means the drug dissolves under the tongue and is not taken with water. Usually, these products are given descriptive names, like “Meltabs.” One new example of a sublingual sildenafil formulation that is commercially available is Wafesil in Australia, which is a wafer formulation that you dissolve under your tongue.

While sublingual sildenafil is slowly creeping into the global market, these products are not available in the US, and importing prescription drugs from other countries is illegal. The FDA has only approved tablet formulations of sildenafil. Viagra’s website warns against other alternative formulations of Viagra, like Viagra for women or “fast dissolving” versions.

When in doubt, shop for Viagra or Staxyn (the FDA-approved sublingual alternative) from a pharmacy you can trust, like eDrugstore.

The Science of Sublingual Viagra

There have been many research studies over the last few decades about the potential to administer sildenafil under the tongue. In one such study in 2003, researchers compared the effects of taking Viagra tablets whole and crushed under the tongue. The result was that the time it took for the drug to be effective was basically cut in half: 62.8 minutes for Viagra swallowed whole vs. 29.3 minutes for crushed Viagra placed under the tongue.

Another study from 2004 compared 20 mg sublingual sildenafil with a placebo in a total of 40 men. Of the men who took the sildenafil, 65% achieved satisfactory erections versus 15% in the placebo group. The average onset time for sublingual sildenafil was 15.5 minutes, and the effects lasted for an average of 40 minutes with minimal side effects. This puts it about on par with Staxyn, the only FDA-approved sublingual ED drug.

More recent trends in research into sublingual sildenafil show the potential for even faster deliveries. A 2016 study published in the Journal of Pharmaceutical Sciences explored the potential for rapid-delivery formulations of sublingual sildenafil in rabbits. In their experiments, the average onset time was less than three minutes, far lower than any ED medication currently available. If these formulations prove to work similarly in humans, sublingual sildenafil may prove to be the fastest-acting ED drug of all time.

Why People Are Interested in Sublingual Viagra

Sublingual Viagra appeals to people for three main reasons: 

  • Potential for a lower effective dose: This will need to be verified as more sublingual products become available, but sublingual medications typically require lower doses since the drug is absorbed directly into the bloodstream from the mouth.
  • Convenience: Some men like the convenience of not having to take a pill with water.
  • Potential for a faster onset time: If the research studies mentioned above and the onset time of other sublingual medications is any indicator, sublingual medication is likely to be faster-acting than tablets.

How to Buy Sublingual Viagra in the United States

Unfortunately, these products aren’t officially available in the United States yet, and it is illegal to import them. One option is asking if your local pharmacy can formulate sildenafil in the form of “troches,” which are medicinal lozenges that dissolve in the mouth. But not all pharmacies can do this.

Do not crush Viagra and put it under your tongue. It will taste terrible, and it may lead to dangerous side effects. The dosages for sublingual and oral medications are almost never the same, so it’s a bad idea to mix methods.

Though you cannot easily obtain sublingual Viagra in the United States, another sublingual ED drug, Staxyn, is available. Staxyn contains the same active ingredient as Levitra, and it is available in a sleek, back pocket-friendly pack of tablets that are made to dissolve quickly on the tongue. Keep in mind, since Viagra and Staxyn contain different active ingredients, the effective dosages differ. Staxyn is currently only available in a 10 mg dosage, which is also the most common recommended starting dose for Levitra.

If you are interested in obtaining Staxyn or another popular ED medication like Viagra conveniently, safely, and at a competitive price, you should consider an online medical facilitator like eDrugstore.com. By contracting with US-licensed pharmacists and physicians, eDrugstore.com has dispensed medications for ED to hundreds of thousands of satisfied customers for 15 years and does so quickly, dependably, and with the utmost care for client privacy.
