What are the benefits of Viagra?

Since it was approved for sale, Viagra sildenafil has helped millions of men in the UK and across the world to treat causes of erectile dysfunction and enjoy a healthier sex life. It is a convenient impotence treatment that can be bought over the counter and online. Viagra can be effective in as little as 30 minutes and can provide men with results for up to four hours. Viagra (also referred to as the 'blue pill') is one of the most widely prescribed impotence treatments and has helped more men treat their impotence problems successfully than both Cialis and Levitra.

How does Viagra work?

Viagra tablets work for patients with ED by increasing blood flow to the penis, so you can achieve an erection sufficient enough for sexual intercourse. In all cases it is essential that you experience sexual stimulation for Viagra to take full effect.

To gain a more thorough understanding of how Viagra works, you first need to understand how an erection is achieved. When you are feeling sexually aroused, a natural substance in the body called cyclic GMP is released to help widen the blood vessels in your penis. This should cause the vessels to dilate, allowing more blood flow to enter the penis, causing it to become erect.

Cyclic GMP is broken down by a different enzyme in the body called phosphodiesterase type 5. However, when present in abundance, this enzyme can restrict blood flow in the penis, even when you are sexually aroused. As a result, your penis will remain flaccid. Sildenafil, the active ingredient in Viagra keeps blood vessels dilated for longer and increases blood flow to the penis. The end result is a stronger erection that can be maintained for longer. As is the case with normal erections, adequate sexual stimulation is required for the medication to take effect and help maintain your erection.

Who can use Viagra?

Most men who are above 18 years of age and suffer from recurrent problems of erectile dysfunction can order a course of Viagra tablets online to improve their sexual health. There are certain conditions or treatments with which you can't use these Viagra tablets, so it's important to answer the online consultation in as much detail as possible.

As with all impotence medication, taking the right dose is very important. The correct dose depends on your health condition. If you are taking Viagra for the first time, it is advisable to try a low dosage and work your way up if required, thus avoiding an unnecessary risk of side effects.

Who shouldn't take Viagra?

You can only buy Viagra online if a doctor has recommended it. A doctor will only prescribe this treatment to you if they are completely sure that you can take it safely. Viagra may not be suitable for those who are suffering from the following conditions:

  • Severe heart disorders or severe heart failure
  • Recent heart attack or stroke
  • Low blood pressure
  • Severely decreased liver function

Can I buy Viagra without a prescription?

In the UK, Viagra (the 'blue pill') is a prescription medication, which means it can only be prescribed to a patient by a UK registered doctor. Any online healthcare provider who claims to offer Viagra without a prescription is operating illegally and may be supplying counterfeit medication.

At euroClinix, our free online consultation service is reviewed by a UK registered doctor, who will issue a prescription if the medication is deemed suitable for the patient. This prescription is then processed by our registered pharmacy, who prepares the medication for dispatch.

Thanks to our express service, we are able to deliver medication to the UK and most European counties the very next day. Same day delivery is also available if you live in London. All information about our delivery service can be found on the delivery page.

What side effects does Viagra cause?

Viagra is a tried and tested impotence treatment that is generally well tolerated if used correctly. As with many prescription medications, some men may be more prone to develop side effects, especially if it is the first time they are using a treatment such as this one. These effects are mostly mild and tend to pass as soon as your body becomes used to the medication.

Some of the most common side effects of Viagra are:

  • Headaches
  • Hot flushes
  • Dizziness
  • Blocked nose
  • Nausea

If you experience anything more serious, contact a doctor straightaway.

Viagra Dosages

Viagra is available in three different dosages – 25mg, 50mg and 100mg. Our UK registered doctors will prescribe a course that is best suited to your needs, which is why it is important to document your medical history in the online medical consultation.

25mg dosage

This is the lowest dose of Viagra available and is typically recommended to men who are aged 65 and over. Patients who have experienced a long history of sexual health problems or those who are currently taking alpha-blockers are given this dosage. If you are a first time buyer of Viagra, this is probably the best dosage to start with as side effects are not at as strong with this low dose and clinical trials have proven to be effective in as many as 63% of men in the experimental group. It is also important to remember that if you are using Viagra for the first time, it may take a few attempts before any significant change in sexual performance occurs.

50mg dosage

This dosage has a very high success rate among ED patients and is therefore the most commonly prescribed Viagra dosage in the UK. In clinical trials, 74% of men in the experimental group experienced positive outcomes after using this dosage.

100mg dosage

If you are completely healthy or if the lower doses of Viagra have had little to no effect on your ability to maintain a strong erection, one of our UK registered doctors will likely prescribe this dosage. Over 85% of the research participants taking the 100mg said the increased dosage helped them sustain a stronger erection. Though there is a slightly higher risk of side effects with this Viagra tablet, there is also a greater chance of it working for patients who need it.

How do I take a Viagra tablet?

Viagra is available to take in three strengths: 25mg, 50mg and 100mg. One tablet should be swallowed whole 30 to 60 minutes prior to sex. The tablet can be taken on an empty stomach or with food, although the desired effects may be reduced if you have recently consumed a large volume of fatty foods. Furthermore, consuming too much alcohol while taking Viagra also weakens its efficacy and can lead to a higher risk of side effects.

The tablet should be swallowed whole with some water. Do not take more than one Viagra tablet in a day. If you would like to take an impotence medication that is optimised for daily intake, Cialis Once A Day would be a better option. If you are unsure which dosage strength to take, contact us and we can help you to decide.

Why are more men buying Viagra online?

Buying Viagra online, rather than buying it over the counter, is becoming ever more popular in the UK. Using an easy to order online service is a good alternative to a doctor's visit. Although erectile dysfunction is no longer considered a taboo topic, many men still prefer not to talk about it. Therefore, going to a doctor is an uncomfortable thought and many men would rather forego sex in the short term. In addition, you can save a lot of time by ordering Viagra pills online, especially due to our free next day delivery service.

Viagra History

Pfizer, a world-renowned pharmaceutical company was responsible for manufacturing Viagra, the fastest selling treatment of all time. However, it is interesting to note Viagra was not used for what it was initially intended. It began as a new medication for angina, a heart condition that constricts blood vessels in the heart. Pfizer was trying to manufacture a treatment that would relax blood vessels, however, its clinical trials did not produce effective results. As they were about to abandon further trials, volunteers from their studies started coming forward to report unusual side effects, namely stronger erections.

Chris Wayman, a senior scientist from Pfizer was given the role of investigating these findings. Soon after, he created a model "man" in the laboratory. He filled a set of test tubes with an inert solution and placed a small piece of penile tissue in each one, taken from an impotent patient. Each penile tissue was joined up to a box that, at the flick of switch, would deliver a small amount of electricity through the tissue.

The investigation was designed to mimic what happens when a man is sexually aroused. Nothing happened the first time, however, when Wayman added sildenafil (the active ingredient contained in Viagra) to the tissue, the blood vessels in the penis suddenly relaxed, just as they would for a man to make his penis erect.

Therefore, thanks to a failed Angina medication, men had a different option and Viagra fast became one of the most prescribed treatments across the world. The medication, named Viagra, was patented for use in 1996, and in 1998, the FDA gave it approval for the sale in the USA. As expected, the sales of this treatment rocketed. Prior to the launch of Viagra, there was no other oral medication for impotence - the only medical options were a prosthetic implant or an injection into the genitals.
