Viagra was one of the biggest innovations in erectile dysfunction treatment in the last several decades.  Until recently, it was still under patent protection, meaning no generic versions were available.  However, that status has changed, and now sildenafil, the generic brand of Viagra, is available.  As sildenafil has been so popular, there’s naturally a great deal of interest among potential users for an affordable, safe, and effective way to buy sildenafil online safely.

As with many medications, supplements, and other health products, it’s not always easy to find legitimate sources online.  Too often, many scammers are selling counterfeit products that may contain no active ingredients or may even be dangerous.  That’s why a lot of people have shied away from buying medications online for many years.

That’s starting to change, however, with the growing popularity of telehealth and telemedicine.  Licensed, board-certified doctors are available for online appointments, writing prescriptions, and coordinating treatment for a range of conditions, including erectile dysfunction.  Choosing a quality telemedicine provider is the most important step in determining where to buy sildenafil online safely.

Below, we’ll get into some of the details on sildenafil and how it works, before offering detailed advice on the things to look out for when you’re shopping for sildenafil online.  Essentially, this is a guide to help you learn where to buy sildenafil online safely – even if you choose a provider other than Invigor Medical.  We want you to stay safe and get what you pay for!  So let’s dive right in.

What is Sildenafil?

To start, let’s recap the basics of sildenafil, including what it is, how it works, and so on before we talk more about where to buy sildenafil online.  For more detailed information on specific aspects of sildenafil, we encourage you to read the other articles and pages on our site related to erectile dysfunction treatments and sildenafil.

In brief, sildenafil is the generic form of Viagra, one of the first oral erectile dysfunction treatments.  Sildenafil is a PDE-5 inhibitor, as that is the pathway through which it does its work in the body.  PDE-5 is an enzyme that exists in the body in various tissues and systems.  One of its functions is to regulate nitric oxide levels. Nitric oxide is involved in the process of dilating blood vessels to increase blood flow.

Without getting too technical, when erectile dysfunction is caused by decreased blood flow, the use of a PDE-5 inhibitor helps make it easier to attain and maintain an erection.  For many men, that’s all that is required to improve or regain full satisfactory erectile function.

The most common side effects from sildenafil are generally mild and transient, and may include headaches, facial flushing, sweating, dizziness, light sensitivity, blurry vision, or nausea.  Another consideration that many men appreciate is that sildenafil does not cause an erection on its own – sexual stimulation is required.  This leaves the sexual response cycle under the control of a man and his partner, rather than causing unwanted erections at inopportune times.

Do You Need a Prescription for Sildenafil?

In the US, sildenafil and brand-name Viagra both require a prescription in order to be dispensed to a patient.  They are powerful medications, and if they are misused or abused, serious health consequences can result.  Therefore, as you’ll see a bit later in our guide to where to buy sildenafil online safely, it’s not as simple as searching for a website and adding the medication to your cart.  You need to have an appointment with a doctor or other licensed healthcare professional to get a prescription that you can then have filled.

Of course, you can do this through the traditional route of visiting your general practitioner, urologist, or other doctor in person.  However, for many men, discussing erectile dysfunction and ED treatments can be an uncomfortable subject.  In addition, there are many hassles related to conventional doctor’s appointments – long lead times, a lot of waiting, exposure to potentially ill patients, high cost, and little face-time with the doctor themselves.  That’s why many men are turning to online doctors, through telemedicine services like Invigor Medical, in order to address their ED treatment and other prescription medication needs.

Typical Purchase Dosage and Format

Sildenafil is usually prescribed for dosing at a minimum of 25 mg and a maximum of 100 mg.  It is supplied as an oral tablet, to be taken with water and swallowed.  Many providers prescribe the 100 mg variety and advise patients who require a smaller dose to divide the pills into halves, thirds, or quarters.  In most cases, this option is more cost-effective for patients.  Availability will likely vary based on your chosen source of where to buy sildenafil online or from a brick-and-mortar pharmacy.

As with any medication, you should only take the dosage you have been prescribed, not more or less.  The lowest effective dose is usually the safest, as increasing the dosage tends not to provide more positive benefits, but does increase the risk of side effects significantly.  Sildenafil is designed to be taken no more than once per day, around 30 minutes to an hour or so before sexual activity.  Its effects last for 3 to 5 hours. 

Taking more than prescribed can result in an erection that lasts for more than 4 hours and does not go away on its own.  This is often painful and is considered a medical emergency, as it can cause permanent damage to the penis.  Therefore, patients should use caution with dosing amounts and schedules.

Where to Buy Sildenafil Online Safely

Many people have seen banner ads or email spam about buying Viagra or generic Viagra (sildenafil) online, often at rock bottom prices.  It’s very important to safely research your chosen provider and make an educated choice if you are looking for where to buy sildenafil online safely.  You want to avoid potential scams and enticing offers that are too good to be true. 

Instead, if you keep the following considerations in mind, you’ll be able to identify quality telemedicine providers (like Invigor Medical), offering legitimate medication from major manufacturers and licensed US pharmacies, delivered right to your door. 

So, without further ado, let’s look at the important things you need to remember when looking where to buy sildenafil online safely.

Telemedicine Consultation

The first and most important thing to consider when trying to find where to buy sildenafil online safely is whether or not a provider offers a telemedicine or telehealth consultation.  Any site that doesn’t offer a consultation with a licensed doctor is likely a scam or fraudulent, as a prescription is absolutely required to obtain sildenafil.  So, be sure to choose a provider that offers a legitimate telemedicine consultation with a board-certified, licensed doctor.

US-Based Providers and Pharmacy

In a similar vein to the above criteria, when you are looking where to buy sildenafil online, it’s useful to do a little digging and research into your potential sources and find out where they are based.  In general, US-based operations are more likely to be legitimate, complying with US laws, and providing legitimate medication and medical services.  That’s not to say there aren’t scams in the US, of course, but it’s much harder for a domestically-registered business to exist for long if they aren’t legitimate than it is for off-shore businesses based in exotic island locales, for instance.  A US-based telemedicine pharmacy, using a US-based pharmacy, will usually be your best bet.

Licensed and Reputable Pharmacy

If a telemedicine provider directly refers prescriptions to a pharmacy, it’s important to ensure the pharmacy is licensed, reputable, and regulated.  After all, that pharmacy filling the prescription will be the source of the medication you are getting.  Therefore, it should be compliant will all relevant federal and state requirements for operation, and not have complaints against it with the BBB or state regulatory authorities where it is based. 

Typically, you can check the status of a pharmacy’s license and operating information on the relevant state health department website for the state in which it is based.  In the case of Invigor Medical, we use the Olympia Compounding Pharmacy in Florida, whose license (#PH27414) can be verified through the Florida Department of Health.

Secure Online Transactions

An often-overlooked consideration when trying to determine where to buy sildenafil online is the safety and security of your chosen provider’s online website or platform.  Naturally, you are dealing with sensitive personal information, health information, and payment/financial information.  You don’t want that to be stolen by hackers in a data breach, for instance.  Therefore, any good online telehealth service should have robust security measures in place.  Some of the easiest to check include using a secure HTTP domain (the address will have https:// at the start rather than just HTTP://) and making sure any transactions are encrypted.  The latter of these measures will show up as a lock icon in most modern browsers when making a purchase or providing any financial information. 

Customer Reviews and Feedback

A valuable and practical way to learn about any online provider’s quality, whether in telemedicine or another area, is by looking at customer feedback and reviews for the service.  This is no different when you are trying to determine where to buy sildenafil online safely.  Until you experience the service yourself, you can’t know exactly what it’s like, but you can learn about other’s experiences and the service’s reputation through reviews and feedback.  Some quick Internet searches will often reveal any significant issues with a provider, and whether or not it is a scam or legitimate service. 

Of course, it’s important to bear in mind that there will likely be some negative feedback online, even for the best service.  Not everyone is happy 100% of the time.  But if the feedback and reviews you find are overwhelmingly negative or consistently problematic on a particular issue or aspect of a service, then that’s probably a red flag for choosing that provider. 

Frequently Asked Questions

Can you take sildenafil with other ED medications?

It can be dangerous to take sildenafil with other ED medications, prescribed or herbal.  Taking more than one medication for ED raises the risk of unwanted and possibly dangerous side effects.  This includes priapism, a painful condition where an erection lasts longer than 4 hours and will not go away.  This is a medical emergency and needs immediate medical treatment, as it can cause permanent damage to the penis.  Therefore, you should only ever take sildenafil as prescribed, in the amount prescribed, and ensure that your health care provider knows all other medications, herbs, and supplements you are currently taking.

How long does it take for sildenafil to work?

Sildenafil is an oral tablet, and therefore must be broken down in the stomach before being absorbed into the bloodstream.  This typically takes around 30 minutes.  However, the time to work can be significantly longer if you have a full stomach or take the medication with high-fat foods – up to 2 hours in some cases.  Taking the medication on an empty stomach is usually the best way to ensure quick results.  In either case, the medication remains effective for between 3 and 5 hours for most people. 

Is sildenafil safe?

Sildenafil is generally considered safe and has relatively minor side effects.  The most common include headaches and facial flushing, seen in around 10% of patients. Other side effects may include dizziness, light sensitivity, blurred vision, and nausea.  More serious side effects can occur but are rare.  Medication interactions are possible, especially with nitrates and other drugs that work on blood pressure or blood flow, so it’s important to disclose all medications you are taking and medical conditions you have to your doctor before starting sildenafil.
