How long does Viagra last?

Viagra, a well-known medication used to treat erectile dysfunction (ED), has been a significant medical advancement. Here, we give you our expert overview of Viagra, what it does, how well it works, and how long it lasts. We’ll also explore a few alternative treatments for erectile dysfunction.

How long does Viagra last?

Viagra typically starts to work within 30 to 60 minutes after ingestion, with its peak effect occurring around the 60-minute mark. The drug remains effective in the system for up to five hours, although its potency begins to decrease after about three hours. During this window, a man should be able to achieve an erection if sexually stimulated. In some men, the effects of Viagra could potentially last as long as 10 hours, and also work as quickly as 12 minutes.

However, it’s essential to understand that the presence of Viagra in the bloodstream does not mean a constant erection for five hours. Erections will subside after ejaculation or if the sexual stimulation ceases.

What is Viagra?

Viagra is the brand name for sildenafil citrate, a drug developed by Pfizer. Originally designed for treating heart problems, it was found to have an interesting side effect: the ability to cause erections. This discovery led to its repurposing and approval for treating ED in 1998 by the U.S. Food and Drug Administration (FDA) and other health authorities around the world.

We recommend generic Sildenafil if you want to try Viagra as a more cost-saving treatment that produces the same results.

Viagra works by increasing blood flow to the penis, helping men, and those assigned male at birth, achieve and maintain an erection sufficient for sexual activity. It’s not an aphrodisiac and you need to be turned on (sexually stimulated) for it to work.

What does Viagra do?

• Improved Erections: Viagra helps men achieve and maintain an erection strong enough for sexual activity by increasing blood flow to the penis.
• Enhanced Sexual Performance: Many people report increased confidence and satisfaction with their sexual performance when they don’t have to worry about their erection.
• Increased Sexual Pleasure: Taking away the worry about getting an erection means people who use Viagra often experience more enjoyable and fulfilling sexual experiences.
• Quick Onset: Viagra typically starts working within 30 to 60 minutes, allowing for relatively spontaneous sexual activity.
• Psychological Benefits: The reliable performance of Viagra can significantly reduce anxiety and stress related to sex.
• Short Duration of Side Effects: Most people experience mild and short-lived side effects, making it a generally well-tolerated medicine.
• Established Track Record: As one of the most well-researched ED medications, Viagra's long history is reassuring regarding its safety and efficacy.

These positive effects make Viagra a valuable treatment option for many men looking to enhance their sexual health and quality of life.

How well does Viagra work?

A study published in the International Journal of Impotence Research found that after 36 and 52 weeks, around 9 in every 10 people felt that treatment with Sildenafil had improved their erections. 1

Another research study reported that 74% of men achieved satisfactory erections with Viagra, and more than half continued using the medication effectively over a period of three years.

Overall, these numbers and clinical data show that Viagra and Sildenafil are potent treatments for erectile dysfunction that can help millions of men regain their sexual function and confidence.

Sildenafil vs. Viagra

Sildenafil and Viagra are pretty much the same medication with different branding. Viagra is the well-known brand name produced by Pfizer, whereas Sildenafil is the generic version of the drug. Both contain the same active ingredient, sildenafil citrate, and are equally effective in treating erectile dysfunction.

The main difference lies in the price, with Sildenafil being more affordable due to its generic status. How well it works, how you take it and the potential side effects are identical, making sildenafil a cost-effective alternative to the branded Viagra.

What causes Erectile Dysfunction?

ED is a common condition that affects men worldwide, particularly as they age. It is the inability to achieve or maintain an erection that is strong enough or lasts long enough to enjoy sex.

Understanding the underlying causes of ED is important for treatment and management. This can include:

• Physical Causes: Physical causes of erectile dysfunction are often related to the body’s way of getting an erection. These include blood vessels (vascular), nerves (neurological), hormonal, and physical factors.
• Lifestyle-Related Causes: Lifestyle choices can significantly impact erectile function. Certain habits and activities are known to contribute to ED, like smoking and drinking too much alcohol.
• Psychological Causes: Psychological factors can play a significant role in erectile dysfunction. Mental health and emotional well-being are closely linked to sexual performance.

Side effects and considerations

Like all medications, Viagra comes with potential side effects. Common side effects include headaches, getting a red face (flushing), indigestion, a stuffy nose (nasal congestion), feeling dizzy, and vision disturbances.

Most side effects are mild and don’t last very long, but severe side effects, such as priapism (a prolonged and painful erection that won’t go down), sudden vision loss, or hearing loss, require immediate medical attention.

It’s also very important to avoid Viagra if you’re taking nitrates for chest pain (angina) or have certain medical conditions, such as severe heart or liver problems. Always let us know about other medicines and medical conditions in your consultation before starting Viagra so we can make sure it’s safe for you.

Alternatives to Viagra

While Viagra is a well-known and effective treatment for ED, several alternatives are available.

Sildenafil (Generic Viagra)
