Viagra is the brand name version of sildenafil.

Doctors usually prescribe Viagra to help relieve erectile dysfunction (ED), which causes a person to have difficulty getting or maintaining an erection.

Following sexual stimulation, taking Viagra helps increase blood flow to the penis, which can help individuals maintain an erection for sexual intercourse. However, doctors do not recommend taking more than one dose of Viagra daily.

This drug can start working within 30 minutes, and its effects can last 4 hours. Although doctors usually prescribe 50 milligrams (mg) of Viagra, they may lower this to 25 mg or increase it to 100 mg.

People can purchase Viagra online from several online pharmacies and telehealth companies.

However, the drug is only available with a prescription. Some online pharmacies can fill an electronic prescription and notify the person when Viagra is available for collection at their local pharmacy. Other online pharmacies offer delivery to the person’s door.

If an individual does not have a current prescription, some online pharmacies and telehealth companies may offer an online consultation with a doctor via a phone or video call. This consultation may lead to the doctor prescribing Viagra, which the company can fill.

However, people should never purchase Viagra from companies that do not require a prescription. One older 2012 study found that 77% of Viagra individuals bought online from companies that did not require a prescription were counterfeit.

A newer 2020 study found that 60% of the sildenafil and tadalafil samples they looked at from online websites were false and inauthentic.

In addition to companies not requiring a prescription, some other warning signs that online Viagra may not be genuine include the following:

  • The company ships the Viagra from a different address than where it claims to be based.
  • The Viagra does not come with a product information leaflet.
  • The Viagra does not come with any safety warnings.

Therefore, people should research companies that sell Viagra to ensure they are not buying counterfeit drugs before purchasing.
