Erectile dysfunction affects more than 30 million men in the United States, but experiencing the condition can feel very lonely as a result of the shame and embarrassment that often affects sufferers.
Viagra, the first medication approved by the U.S. Food and Drug Administration (FDA), became available in the United States in 1998.
However, many men resist getting treatment for erectile dysfunction because they are too embarrassed to speak to their doctor about their symptoms.
While Viagra is only available with a prescription, it is possible to buy sildenafil from online pharmacies and telehealth services, and avoid a potentially embarrassing trip to the doctor’s office or local pharmacy.
We’ve put together a list of the best online sources for Viagra, which is also sold under the generic name of sildenafil.
What is the generic form of Viagra?
Sildenafil citrate is best known as the generic form of Pfizer’s Viagra, but it is also sold under the brand name Revatio.
When sold as Viagra, sildenafil is used to treat ; when marketed as Revatio, the prescription drug is used to treat high blood pressure and pulmonary arterial hypertension.
Sildenafil first became available in December 2017 when the original manufacturer’s patent for Viagra ran out, allowing other manufacturers to produce a generic version of the drug.
Due to the increased availability and the number of different manufacturers, it is much cheaper to buy generic sildenafil than Viagra, with the generic working exactly the same way and being equally effective to the famous little blue pill.
Sildenafil is primarily given in doses of 20 mg, 40 mg, 60 mg, 80 mg, or 100 mg, depending on the patient and on the condition being treated.
How do I use Viagra to treat sexual dysfunction?
Sildenafil (Generic Viagra) works differently than many other prescription medications.
Rather than taking the medication daily in the morning or at night, sildenafil is taken 30 to 60 minutes prior to sexual activity, although it can be taken up to four hours before sex.
The medication should not be taken more than once every 24 hours, but some patients may not be able to take the medication that often due to their medical history.
Sildenafil can be taken with or without food, but it works more slowly if it is consumed around the same time as a high-fat meal, as the digestion of fat delays the effects of the medication.

Who should not take Viagra?
Sildenafil (Generic Viagra) is sold by prescription only and is not available over the counter because it can be dangerous for some groups of people with certain medical conditions, and others may be prone to a higher risk of experiencing serious side effects.
People taking medications called nitrates, which are often prescribed for chest pain, or guanylate cyclase stimulators such as Adempas (riociuguat) for pulmonary hypertension, could experience an unsafe drop in blood pressure if taking sildenafil and should not use the medication. Additionally, people who are allergic to sildenafil or any of its ingredients should not take the medication.
Sildenafil can cause cardiovascular side effects including heart attack, stroke, irregular heartbeat, and death.
These side effects are rare and typically occur in patients who had a previous history of heart problems prior to taking the medication, so patients with a history of heart problems or who are at high risk of experiencing heart problems should talk to their doctor about their medical history before taking sildenafil.
Best Online Sources for Viagra
Although sildenafil and Viagra is sold by prescription only, the topic of erectile dysfunction is difficult for many men to talk about with their doctors.
Additionally, finding the time to go to the doctor’s office is a hassle.
Recognizing this issue, several online services have popped up in recent years that make consulting with a healthcare provider easier, more private, and more convenient. It’s now easier than ever to purchase genuine sildenafil online.

Hims
Hims is a men’s healthcare and personal wellness company with the goal of making it easier for men to take care of their health.
To sign up for Hims, patients create a profile online that includes information about their medical history, symptoms, general health, and lifestyle.
To verify their identity and ensure that your doctor is treating the right person, patients must also supply a government-issued ID card, like a driver’s license, and a credit card, all of which are stored on a secured, encrypted platform.
Sildenafil is the active ingredient in Viagra, which is FDA approved to treat ED. It improves blood flow to the penis by relaxing blood vessels and smooth muscle. The result is a harder and longer-lasting erection. We offer this popular ED treatment at a fraction of the brand name price.
Once your profile has been created, patients are connected virtually with a licensed healthcare provider in their state.
Some states require a video consultation, while others do not. Your healthcare provider will discuss your medical history, symptoms, diagnosis, and treatment options with you.
If your doctor feels that you can safely take medication to treat your erectile dysfunction, they will write you a prescription and your medications will be shipped to you discretely by mail.
Each dose comes either individually wrapped or in a bottle, depending on the medication that is prescribed.
Hims makes it easy to purchase sildenafil or Viagra online and save money.
You don’t have to waste your time driving to the doctor’s office, and there is no copay.
Patients can be assured that their information is confidential and that they will receive genuine Viagra or its generic equivalent, sildenafil, if you choose.
Due to the popularity and high cost of Viagra, Viagra and other erectile dysfunction medications are among the most commonly counterfeited drugs on the market.
These counterfeit Viagra drugs can be ineffective at best and potentially dangerous at worst, so finding an online source you can trust, like Hims, is of the utmost importance.
Sildenafil is available from a cost of four dollars per use through Hims, compared to Viagra, which starts at a cost of 70 dollars per use.
BlueChew
BlueChew, another reputable online resource for erectile dysfunction medications, offers treatment for men who cannot tolerate commercially available pills like Viagra and Cialis. The company also solves the problem of the inconvenience of in-person doctor’s appointments by providing a telehealth consultation for patients who want to improve their chance of achieving erection.
One of the things that sets BlueChew apart from other online men’s health providers is that the company focuses solely on treatments for erectile dysfunction and creates compounded treatments that use only FDA-approved active ingredients of sildenafil or sildenafil but are uniquely suited to each patient’s needs.
That means that patients receive a dose of the medication that is appropriate for them and their medical history rather than the same standard commercially available formula.
The company also offers a number of different monthly subscription options ranging from six to 34 tablets of sildenafil per month in a strength of either 30 or 45 mg.

Like other telehealth providers, BlueChew requires that patients upload a photo that shows both their face and their government-issued ID in order to confirm their identity before matching you with a licensed healthcare provider in your state.
As with other telehealth providers, some patients will have to video chat with a doctor to meet their state’s requirements, while others may be able to have their entire consultation done by answering questions virtually. Regardless of how your consultation is done, you’ll never have to leave your home.
If your healthcare provider determines that you need a prescription, they will write one for you. Patients then have the option of choosing to have BlueChew fulfill the prescription or taking the prescription to the compounding pharmacy of their choice.
BlueChew offers sildenafil at a number of different price points depending on a patient’s individual needs. A patient can receive six chewable tablets of sildenafil for as little as 20 dollars per month, depending on the dose, or 34 chewable tablets for as little as 90 dollars per month. The medication is refilled monthly and is shipped discreetly.
