How it Works

About Viagra

What is Viagra?

Viagra is a prescription-only medication indicated for treating erectile dysfunction (ED) in men. Studies have shown it is effective for around 74% of men who try it. Its mechanism involves increasing blood circulation to the penis, assisting men with ED in obtaining and sustaining an erection when sexually stimulated. Typically, Viagra takes around 60 minutes to start working after consumption, and its effects can last for as long as 4 hours.

Why do I need to get a prescription?

Viagra is classified as a prescription medication, which necessitates a doctor's evaluation to ensure its safety for your specific health conditions. This precaution is in place because Viagra can interact with certain medications or may not be suitable for individuals with specific health issues. There exists a variant, known as Viagra Connect, which is available without a prescription from a dentist. However, even with this alternative, a pharmacist will require you to undergo an assessment first.

What causes erectile dysfunction?

Erectile dysfunction is a prevalent condition influenced by numerous physical and psychological components. Among the common physical causes are obesity, cardiovascular diseases, and hypertension. Psychological factors contributing to ED often include stress, anxiety, and depression. Typically, many factors contribute to erectile dysfunction, rather than merely a single issue. For further insights, refer to our medical professionals’ guidance on the causes of erectile dysfunction.

How does Viagra work?

Viagra is classified as a phosphodiesterase-5 (PDE-5) inhibitor. It functions by temporarily enhancing blood flow to the penis, aiding in achieving and maintaining an erection.

Upon ingestion, sildenafil, the active component, relaxes the smooth muscles within the penis’s blood vessels, promoting increased blood flow that results in an erection.

It is crucial to note that Viagra requires sexual arousal to be effective, as it does not induce an erection independently.

How effective is Viagra?

Clinical trials demonstrate that Viagra 50mg is effective for 74% of men who take it, with the 25mg dose exhibiting an effectiveness rate of 62%, while the maximum 100mg dose is effective for 82% of men compared to a placebo (a non-medicated pill).

How to take Viagra

You should take Viagra approximately 1 hour prior to your planned sexual activity. Swallow one viagra tablet with a glass of water. It is important to limit your intake to 1 Viagra tablet within a 24-hour period.

For optimal effectiveness, it is advised to take Viagra on an empty stomach and to select lighter meals if you plan to eat beforehand, as heavy or greasy foods can delay the medication’s effects.

Furthermore, drinking alcohol while using Viagra may decrease its effectiveness as alcohol can hinder the ability to achieve an erection, even in instances where erectile dysfunction is not present. Therefore, it’s wise to reduce your alcohol intake in conjunction with Viagra usage.

When to take Viagra

Viagra typically takes around 30 to 60 minutes to begin working. Consequently, you should consider taking it approximately 1 hour before you intend to have sexual intercourse. Taking it more than 4 to 6 hours before your intended activity may render the Viagra ineffective, requiring you to wait until the following day to retry.

How long does Viagra take to work?

Generally, Viagra begins to take effect within 30 to 60 minutes post-ingestion. Hence, it’s recommended to take it about 1 hour before your expected sexual encounter.

Several factors may influence the onset time of effectiveness for Viagra:

  • Arousal: Engaging in sexual stimulation is necessary for Viagra to take effect. Without arousal, Viagra will not provide the expected results. Exploring foreplay with your partner while waiting for the medication to take effect can enhance the process.
  • Food: Certain foods, particularly heavy or fatty ones, can delay Viagra’s effects. It’s acceptable to take Viagra with or without food; however, if you decide to eat, opting for lighter options is recommended.
  • Alcohol: Alcohol can negatively impact erectile function, even in cases where you don’t experience erectile dysfunction. Therefore, it is best to limit alcohol intake while using Viagra.

How long does Viagra last?

Viagra generally remains effective for up to 4 hours after consumption, although this duration may vary slightly. Thus, if engaging in sexual activities in the evening, it’s wise not to take it too early in the day, especially since you can only take it once every 24 hours. Taking it one hour before sexual activity is advisable.

A variety of factors can affect how long Viagra remains effective, including age, overall health, dietary habits, and alcohol use.

How often to take Viagra

Viagra should not be administered more than once a day. Exceeding the prescribed dose, such as taking multiple tablets within a single day, may elevate the risk of side effects and potentially serious complications, including irreversible damage to your penis.

If you feel the prescribed Viagra dose is too strong or too weak, consult your doctor for guidance. It's important not to adjust your dosage without professional advice.

Viagra dosage

Viagra is available in three different dosages: 25mg, 50mg, and 100mg. The higher the dosage, the stronger the effect; however, increased dosages may also elevate the likelihood of experiencing side effects. It might be beneficial to explore various dosages to determine which one suits you best.

Viagra 50mg

Viagra 50mg is typically the standard initiation dose prescribed for most patients, and is often recommended for individuals who are trying Viagra for the first time. This dosage is the most commonly utilized and tends to be effective for the majority of men.

Viagra 25mg

Viagra 25mg is the lowest available dose of Viagra. While it is slightly less effective than the 50mg variant, it is also less associated with side effects. Opting for this dosage may be ideal if you have previously utilized 50mg and experienced side effects that you would prefer to avoid. It could also be suggested if you’re on other medications to minimize the risk of interactions.

Viagra 100mg

Viagra 100mg represents the highest prescribed dosage available in the market. It has a higher effectiveness rate compared to lower doses, but may also carry an increased risk of side effects. This dosage might be suitable if the 50mg variant did not yield desired results and you did not experience side effects.
