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. There is a possibility that companies will sell products that do not contain the ingredients they should.

For example, a 2020 study found that 60% of vardenafil the researchers looked at was falsified and inauthentic, containing other PDE5 inhibitors.

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.

There are two ways to get a Viagra prescription: in-person or online.

In-person prescription

Getting an in-person prescription requires an appointment with a healthcare professional with the authority to prescribe medication.

If a person has insurance, they should contact their provider to ensure the doctor they wish to consult is in-network. People may also wish to check that the hospital the healthcare professional uses is in-network.

ED may be a sensitive topic for some people. Due to this, a person should always make sure they feel comfortable talking about their health with the doctor.

If a person feels uncomfortable during an initial consultation or finds that the healthcare professional does not explain their condition and medication in a way they can understand, they may wish to change doctors.

Once a person has their prescription, they can receive the medication at their local pharmacy. Some pharmacies may offer coupons that help reduce the cost of the medication.

Online prescription

Some online pharmacies and telehealth companies will connect them with a healthcare professional for a fee if a person does not have a valid prescription.

Many companies ask that people complete a questionnaire detailing their concerns and the medication or treatment they want to try. Then, the service will connect the person to a healthcare professional who will ask further questions and prescribe treatment if necessary.

Companies will then send medication to a person’s address or a local pharmacy.

For most online pharmacies, a person must begin by signing up to the company’s website. Here, a person may need to pay a subscription fee to the service or just need to fill in some personal details.

Most companies offer a shipping service directly to a person’s house or to a local pharmacy in discreet packaging. This may take, on average, 3-7 days. However, in some cases, a person may be able to pick the prescription up from a local pharmacy on the same day.

Viagra is the brand name version of sildenafil.

Doctors usually prescribe Viagra to help relieve 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 who use Viagra may notice that they find it easier to get and keep an erection. However, before using the drug, they should also discuss potential safety considerations with the healthcare professional in their online consultation.

The sections below look at some advantages and disadvantages of getting Viagra online.

Advantages
