Viagra is a very popular treatment for erectile dysfunction (ED) produced by the pharmaceutical company Pfizer.
It has transformed the lives of millions of men and is clinically proven to help achieve erections strong enough for penetrative sex.
The same treatment is available as the generic version - sildenafil. Sildenafil contains the same ingredients and has identical effects - the only difference is the name and price.
As with most ED treatments, Viagra belongs to a class of medication known as PDE-5 inhibitors. Other treatments in the same class of drugs include Cialis, Levitra, and Spedra - each with their own unique characteristics.
Please note, for any of these treatments to work, you must first become sexually aroused.
Put simply, Viagra works by increasing blood flow to the penis.
An erection occurs when sexual arousal stimulates the brain. Your brain then initiates the body's production of something called cGMP. This chemical relaxes the muscles in the penile wall, allowing the arteries in the penis to fill with blood. The end result is an erection.
When you have climaxed, your body will then produce an enzyme called PDE-5. This enzyme breaks down the erection.
For some men, the PDE-5 enzyme is overly active. This prevents proper function and limits the flow of blood to the penis.
Viagra works through its active ingredient 'sildenafil citrate', which inhibits the PDE-5 enzyme for a period of time, meaning the arteries in the penis can fill with blood.
There are three prescribed dosages with varying strengths of 25mg, 50mg and 100mg, all of which are available to order online with HealthExpress.
If you are unsure which strength to take, you should first consult with a doctor.
You should always follow the directions of your doctor and what is detailed in the patient information leaflet (PIL).
This medication is very easy to take:
Please note, the time it takes for this treatment to work varies between men. It will normally take between 30 minutes and one hour.
If this medication does not have any effect, please contact your doctor.
*Taking a dose of more than 100mg will not increase the efficacy - however it will increase the severity of side effects. If you would like to take an impotence medication that is optimised for more frequent sexual intercourse, Cialis Daily would be a better option.
If you eat a heavy meal (especially a fatty meal), you may find that this medicine takes a longer time to take effect. However, it is completely fine to take with meals, as long as you expect a slight delay before effects.
Alcohol can prevent a man from achieving an erection. For this reason, it is not advised to drink heavily when taking this medication.
All prescription medication can cause adverse effects. Thankfully Viagra is very well-tolerated and any reactions are not normally serious.
The following are the most commonly reported (they are usually mild and not long-lasting):
If you experience any of the above and it causes you distress, please stop treatment and contact your doctor.
You should also stop treatment and seek immediate medical attention if you suffer an allergic reaction, chest pain or painful erections.
A full list of reactions and their frequency can be found in the patient information leaflet - this will be included with your order.
