Believe it or not, Viagra (sildenafil) is one of the most popular medications in the U.S. The blue, diamond-shaped pill is known for its ability to help men fight back against erectile dysfunction (ED). However, Viagra’s popularity doesn’t mean the medication is always self-explanatory.
If you’re using this medication for the first time, here’s how to take Viagra for the best results.
What is Viagra?
Viagra is a prescription medication commonly used to treat ED, a condition that affects over 150 million people worldwide. While the brand-name prescription comes in a blue tablet form, generic sildenafil is a white tablet. Viagra and its generics are prescribed as 25 mg, 50 mg, and 100 mg tablets.
Sildenafil can also treat pulmonary arterial hypertension, a type of lung high blood pressure. However, only Revatio-equivalent sildenafil is FDA-approved for this particular condition.

How does Viagra work to treat ED?
When you’re aroused, your body releases nitric oxide down below. This compound is a molecule that triggers the events responsible for an erection. But an enzyme (protein) called phosphodiesterase type 5 (PDE5) breaks down certain messengers involved in this process, preventing the desired effect.
While there are several reasons why someone may have difficulty getting or maintaining an erection, PDE5 inhibitors that block this enzyme, such as Viagra, are often used as a remedy.
Viagra and other PDE5 inhibitors, such as Cialis (tadalafil) and vardenafil, help relax muscles and arteries inside the penis. This process helps more blood reach the penis. When aroused, the combination of relaxation and increased blood flow helps fill the penis with blood. That’s how you’re able to achieve an erection.
How to take Viagra for the best results
Here are a few tips on how to take Viagra safely and effectively.
The standard recommended Viagra dosage for treating ED is 50 mg. But your prescriber could recommend taking anywhere from 25 mg to 100 mg per dose, depending on how you respond.
You should only take Viagra once a day. This implies that if you plan to engage in sexual activity more than once throughout the day, you should avoid taking a pill every time. And if you take a pill and it doesn’t work for you, donot take another one. Exceeding the recommended Viagra dosage can put you at risk for serious side effects.
Because Viagra can also affect other parts of the body, such as the heart and lungs, it’s important to stick to the dose and instructions your prescriber provides. And if your prescribed Viagra dose isn’t working for you, they may make adjustments to find one that works.
Take it on an empty stomach
You can take Viagra with or without food, but it works best on an empty stomach. So, to maximize its effects, try to take it separately from meals.
But if you eat beforehand, avoid taking it with a high-fat meal. Eating fatty foods can slow down the absorption of the medication and prolong the time it takes for Viagra to start working.
Know the potential side effects of Viagra
The most common Viagra side effects include:
Flushing
Indigestion or heartburn
Headache
Insomnia
Changes in vision
Nosebleeds
Nasal congestion
More serious side effects are also possible. Viagra and other ED medications can rarely cause dangerously long-lasting erections. An erection lasting longer than 4 hours is known as priapism. If left untreated, this condition can cause permanent damage to the tissue that helps you become erect. We will delve deeper into this topic in a later section.

What’s more, your prescriber may warn you not to use Viagra if you have certain heart conditions or take blood pressure medications that relax your blood vessels, including nitrates like isosorbide, dinitrate, or nitroglycerin. Such caution is due to the increased risk of heart attack or dangerously low blood pressure.
How long does it take Viagra to work?
After taking Viagra, the medication quickly enters your system. Viagra should start working within an hour. But this timeframe can vary for different people. You can take it anywhere from 30 minutes to 4 hours before sexual activity to see how it affects you.
You may be wondering if there are ways to help Viagra work even faster, such as chewing or crushing the tablet and dissolving it under your tongue. However, this is not the intended method of action. Viagra should be swallowed whole.
How long does Viagra last?
The effects of Viagra usually last 4 to 8 hours. The specific time frame Viagra lasts depends on the person and the dose you take. In fact, some people may experience more than one erection during this time.
But just because Viagra lasts 8 hours doesn’t mean your erection should. If your erection lasts more than 4 hours — even if it is not painful — seek medical help right away. Treat priapism immediately to prevent potential long-term damage.
If you have sickle cell anaemia, multiple myeloma, leukaemia, or certain penile deformities (such as Peyronie’s disease), you’re more likely to have a prolonged erection.
Does Viagra make you last longer?
Not typically. Just as there are several reasons why someone experiences ED, the same goes for premature ejaculation. And while medications like Viagra can help your erection stay firm, it usually aren’t the first choice for preventing ejaculation.
However, the two issues often happen together. Your prescriber may recommend taking Viagra to help address ED. As a result of treatment, you may see some improvement with how long you last.
If you’re still not lasting as long as you’d like during sex, your prescriber may have you try behavioural methods (e.g., practising ejaculation control), counselling, or other medications — such as numbing creams or antidepressants — to help.
The bottom line
Viagra (sildenafil) can be an effective option to help you achieve and maintain an erection. To get the best results, take Viagra on an empty stomach at least an hour before sexual activity, and follow the instructions from your prescriber. If your erection lasts over 4 hours, get medical attention right away to avoid possible long-term damage.
