What is Viagra?

Viagra is the brand name given to a medication called sildenafil. It has helped millions of men with erectile dysfunction (ED) achieve and maintain an erection when they are sexually aroused.

How does Viagra work?

To properly understand how Viagra works, it is essential that you know the mechanisms behind getting an erection.

When you are sexually aroused, the blood flow to your penis increases by approximately 20 times. In order for this increased blood flow to enter the penis, a molecule called cGMP needs to be released which instructs the veins in your penis to relax. The blood is allowed to enter and your penis will become erect.

Erection problems occur when the circulatory process above isn’t working properly and this is exactly where impotence pills like Viagra can help you. The active ingredient in Viagra, sildenafil, widens and relaxes the arteries in the penis, allowing more blood to enter, engorging the penis to create an erection.

Are there any side effects?

Most prescription medications carry potential side effects so it’s essential that you read the label or patient information leaflet before you take any medication.

Most of Viagra side effects are relatively mild and rarely last more than an hour or two. Side effects such as headache, indigestion and flushing have been reported in less than 10% of all people using Viagra.

Other side effects such as nausea, rash and chest pain are experienced by a very small amount of people using Viagra. For people that are displaying these side effects, it is generally advised that you use a lower dosage of Viagra.

How long does Viagra take to start working?

For most men, Viagra starts to work in about 30 to 60 minutes. In order to get the quickest results from the treatment, it is advised that you avoid a high fat meal before taking it. Food that is high in cholesterol can slow down your body’s ability to absorb the medication.

How long does it stay effective for?

In most cases, Viagra lasts for approximately 4 hours but this doesn’t mean you will have a constant erection throughout this period. Viagra will only work when you become sexually aroused within this period. After climaxing, you will lose your erection like normal but will be able to achieve an erection if you become sexually stimulated again during the 4 hours. Remember, the effects of Viagra vary from person to person.

What are the differences between the dosages 25mg, 50mg and 100mg?

Viagra is available at HealthExpress in three different dosages – 25mg, 50mg and 100mg. In clinical studies, over 60% of men using the 25mg dose reported better erections, over 70% of men taking the 50mg reported a positive response, while 85% of men taking the 100mg dose said that Viagra had helped them achieve and maintain a better erection.

25mg dosage – This is the lowest dose of Viagra and is recommended for men aged 65 or over, those who have underlying health issues or for those who are taking medicines called alpha blockers. 25mg dose may also be recommended if you have been experiencing side effects on the higher dosages of Viagra.

50mg dosage – Our doctor is likely to start you off with this dosage.

100mg dosage - This is the maximum dosage of Viagra available and is only prescribed in men who are fully healthy.

In all cases, the maximum recommended dosing amount is one tablet per day. If you are unsure of which dosage you want, our doctors will personally recommend you the most suitable treatment dosage.

How does Viagra compare with other impotence treatments?

All treatments for erectile dysfunction (Viagra, Cialis and Levitra) work by increasing the blood flow in the penis so that a man can achieve erections when he is sexually aroused. There are, however, small differences between the treatments.

Both Viagra and Levitra take effect in about 30 minutes but Levitra lasts for about 5 hours compared to Viagra, which last for 4 hours on average. Levitra is generally seen as a suitable option for men with underlying health conditions such as diabetes or high cholesterol.

Cialis works faster than other treatments (within approximately 15 minutes) and also stays effective for longer (up to 36 hours.)
