How it Works

About Viagra

What is Viagra?

Viagra is a prescription-only medication formulated to treat erectile dysfunction (ED) in men, and works for around 74% of men who utilize it. It enhances blood circulation to the penis, enabling men experiencing ED to achieve and maintain an erection when sexually stimulated. Viagra typically takes up to 60 minutes to become effective after consumption, with lasting effects for up to 4 hours.

Why do I need to get a prescription?

As a prescription-only medication, Viagra necessitates a doctor's evaluation to ensure its safety for you. This precaution is crucial as it may interact adversely with certain medications or may be unsuitable for individuals with specific health issues. There exists a variant known as Viagra Connect which can be acquired without a prescription, though an assessment by a pharmacist remains obligatory to ascertain its compatibility with your health.

What causes erectile dysfunction?

Erectile dysfunction is a prevalent condition influenced by an array of physical and psychological factors. Common physical contributors include obesity, heart ailments, and high blood pressure. From a psychological perspective, stress, anxiety, and depression frequently play significant roles in ED. In many cases, several variables concurrently contribute to erectile dysfunction rather than a singular cause. For further insights, explore our doctors' guidance regarding the causes of erectile dysfunction.

How does Viagra work?

Viagra is part of a class of drugs known as phosphodiesterase-5 (PDE-5) inhibitors. It functions by temporarily enhancing blood flow to the penis, thus assisting in both achieving and maintaining an erection.

Upon ingestion, sildenafil, the active component of Viagra, relaxes the smooth muscles surrounding the blood vessels in the penis, leading to increased blood flow that results in an erection.

However, it's imperative to understand that Viagra requires sexual arousal to be effective; it won't induce an erection without stimulation.

How effective is Viagra?

Clinical studies indicate that Viagra 50mg is effective for 74% of men who use it. The 25mg variant shows 62% efficacy, while the highest dosage of 100mg boasts 82% effectiveness in comparison to a placebo (a non-active pill).

How to take Viagra

You should consume Viagra approximately 1 hour before engaging in sexual activity. Swallow one tablet with a glass of water. It’s crucial that you don't exceed one Viagra tablet within a 24-hour timeframe.

For optimal effectiveness, it's advised to take Viagra on an empty stomach. If you intend to eat prior to taking Viagra, select a light meal rather than a heavy or greasy one, as such meals can delay the onset of its effects.

Using Viagra alongside alcohol may diminish its effectiveness. Alcohol can complicate erectile function, so it's advisable to restrict or eliminate alcohol consumption while using Viagra.

When to take Viagra

Viagra typically requires thirty to sixty minutes to exhibit its effects; therefore, it is recommended to take it around one hour before anticipated sexual activity. If you consume Viagra more than four to six hours before you wish to engage in sex, it may lose its effectiveness, necessitating a wait until the following day to try again.

How long does Viagra take to work?

Viagra commonly takes between thirty to sixty minutes to start working. Consequently, it is advisable to consume it around one hour before you desire sexual activity.

Several factors can influence the time Viagra takes to become effective:

  • Arousal: Sexual stimulation is essential for Viagra to work. Without arousal, its efficacy diminishes. Engaging in intimate foreplay while awaiting the effects of Viagra can help expedite the process.
  • Food: Certain foods, particularly heavy, fatty, or greasy meals, may prolong the time it takes for Viagra to take effect. While you can take Viagra with food, opting for lighter meals is advisable.
  • Alcohol: Consumption of alcohol may interfere with erectile function, even in individuals without ED. Thus, you should avoid alcohol intake when using Viagra.

How long does Viagra last?

The effects of Viagra can last for up to four hours after consumption, although this duration may vary. If planning sexual activity in the evening, refrain from taking Viagra too early in the day since you are only permitted to take one dose within a 24-hour period. It is generally recommended to take Viagra one hour ahead of sexual engagement.

Multiple factors may affect how long Viagra’s effects persist, including age, overall health, dietary habits, and alcohol consumption.

How often to take Viagra

It’s crucial to not exceed one dose of Viagra per day. Taking more than the prescribed amount, such as two doses within a single day, significantly raises the risk of side effects and could lead to serious complications, including irreversible injury to your penis.

If you suspect that the Viagra dosage you have been assigned is either too high or too low, consult your physician for guidance. Never adjust your dosage without professional advice.

Viagra dosage

Viagra is available in three distinct dosages: 25mg, 50mg, and 100mg. The higher the dose, the more pronounced its effects, but an increased dosage may correspondingly elevate the risk of side effects. It's advisable to consider various dosages to determine which one delivers optimal results for your specific needs.

Viagra 50mg

The standard initial dose for most individuals is Viagra 50mg, which we recommend if you are new to Viagra. This dosage is the most commonly prescribed and tends to be effective for most men.

Viagra 25mg

Viagra 25mg is the lowest available dose. Although it is slightly less effective than the 50mg variant, it carries a reduced likelihood of side effects. If you have previously taken 50mg and experienced undesirable side effects, this may be a more suitable option. This dosage may also be recommended if you're on other medications to minimize potential interactions.

Viagra 100mg

Viagra 100mg represents the highest dosage, providing enhanced effectiveness compared to lower dosages, albeit with an increased risk of side effects. This dosage may be the best choice if you found the 50mg dose ineffective and experienced no adverse reactions.

Non-prescription options

Choices of over-the-counter and non-prescription alternatives to Viagra include:

  • Viagra Connect: an over-the-counter form of Viagra that does not require a prescription.
  • Superdrug sildenafil: a generic variant of Viagra available for purchase without a prescription at Superdrug pharmacies, though a health questionnaire must still be completed and reviewed by a pharmacist.

While moderate alcohol consumption is generally permissible, it is not advisable, as alcohol can exacerbate erectile dysfunction and delay Viagra’s effects, thereby increasing the likelihood of adverse side effects.
