What is Viagra

Viagra is the brand name of the medication sildenafil. It has helped millions of men with erectile dysfunction (ED) and has been clinically proven to help men with erectile dysfunction (impotence), to achieve an erection strong enough for intercourse with their partner.

Viagra, like most erectile dysfunction treatments, is under the class of medication known as PDE-5 (Phosphodiesterase type 5) inhibitors, and will only work when the user is sexually aroused.

How does Viagra work?

An erection occurs when sexual arousal stimulates signals in the brain which increases nitric oxide levels. This in turn stimulates the production of the cyclic guanosine monophosphate (cGMP), which relaxes the muscles in the penile wall, allowing the arteries in the penis to fill with more blood causing it to be erect. Men with impotence (erectile dysfunction) have an impaired cGMP function, as the PDE-5 enzyme responsible for degrading cGMP in the body is too active, preventing its correct function in causing an erection.[1]

Viagra simply works by inhibiting this PDE-5 enzyme for a certain amount of time, allowing the cGMP chemical to function properly, which widens and relaxes the arteries in the penis, allowing more blood to fill the penis, creating a stronger erection.

What are the benefits of Viagra?

The main benefit of Viagra (sildenafil) is the ability to help men achieve an erection, however there are other valuable health points to be noted:

  • Can be used by men struggling to maintain a strong enough erection
  • Can help to improve sexual confidence
  • Suitable for men with coronary artery disease (as long as no other medication that can interact in a harmful way is also being used)

How long does Viagra take to work?

Viagra is usually effective within 30-60 minutes of use for the vast majority of users. The most common factors that may delay its effectiveness include:

  • Consumption of fatty meals before use
  • Consumption of high amounts of alcohol

It is best to avoid these, as they may delay the absorption of the pill into your system.

How long does it last?

A Viagra pill usually lasts up to 4 hours in the system and should wear off after that period of time. Remember, the effects of Viagra do vary from person to person. Due to the nature of the treatment, it should only be used once every 24 hours.

"Effective within 30-60 minutes for the vast majority of users" clock
"Lasts up to 4 hours" clock

How to use Viagra tablets

viagra One tablet should be taken with water at least 30-60 mins before intercourse (preferably on an empty stomach). The tablet will only work if you're sexually aroused. The tablets should only be taken when needed. The pill pack should be stored at room temperature It is not advised to take more than one tablet in 24 hours for health reasons.

You can find more details about safety measures and the use of this treatment in the patient leaflet or the Viagra questions and answers page.

Viagra dosages

This erectile health treatment comes in only three prescribed dosages 25, 50 and 100mg, which are all available here.

Viagra 25mg

Lowest dosage - the 25mg capsules are recommended for those sensitive to higher dosages of the medication and men over the age of 65.

Viagra 50mg

Standard dosage - this is usually the recommended healthy dosage to start on when first using this ED treatment. This enables the user to know whether the medication is effective or whether dosage alteration is required.

Viagra 100mg

Maximum dosage - this dosage is only recommended for those who see little to no change when taking the 50mg dosage. Those who have not experienced any side effects when taking the 50mg tablet may also be able to use this dosage.

In the clinical studies carried out, the effectiveness of Viagra (sildenafil) was higher depending on the dosage:

  • 25mg - over 60% taking the smallest dosage record a stronger, longer lasting erection
  • 50mg - over 70% of men taking this dosage record a stronger, longer lasting erection
  • 100mg - 85% of men that take 100mg dosage record a stronger, longer lasting erection

Pfizer Viagra (Manufacturer)

Pfizer created Viagra in 1989 to be used for the treatment of high blood pressure and angina, however it wasn't very successful in initial trials and the project was to be abandoned. Fortunately for Pfizer, the men involved in the trials reported an unexpected reaction to the medicine - stronger erections after its use. Thus, Pfizer looked to produce a treatment for ED. The FDA approved it almost a decade later, in 1998, as the first prescription treatment to combat erectile dysfunction.
