Review shows dangers of erectile dysfunction drugs sold on the internet

A review from scientist in the UK, US and Sweden reveals that 90 percent of drugs for erectile dysfunction are now sold on the internet. Purchasing drugs to treat ED and other diseases from the internet can harm health by bypassing needed health. Many of the drugs also contain harmful ingredients.

The dangers of counterfeit drugs sold on the internet can also pose health risks from the impurity of the products. According to a review of studies, 2.3 million drugs for erectile dysfunction are sold monthly on the internet and mostly without prescription. Additionally, 44 per cent of the Viagra offered on the internet is counterfeit.

The focus of the analysis was on drugs sold on the internet to treat erectile dysfunction from 1995 to 2009, and included more than 50 studies.

Graham Jackson, a London-based cardiologist who led the study says, “We discovered that 150 patients had been admitted to hospitals in Singapore after taking counterfeit tadalfil [Cialis] and herbal preparations that claimed to cure ED. Seven were comatose, as the drugs contained a powerful drug used to treat diabetes, and four subsequently died.”

Jackson warns that erectile dysfunction drugs are not the only counterfeit medications sold on the internet. “In Argentina, two pregnant women died after being given injections of a counterfeit iron preparation for anaemia and 51 children died in Bangladesh of kidney failure after taking paracetamol [acetaminophen] syrup contaminated with diethylene glycol, which is widely used as car antifreeze.”

Fake drugs sold on the internet included contraceptive and antimalaria pills, counterfeit antibiotics and water sold as a vaccine for meningitis. According to rough estimates, there could be as many as 2.5 million men in the Europe using counterfeit Viagra obtained from the internet without physician prescription or medical exam because of the embarrassment associated with erectile dysfunction. Analysis of ED drugs shows that some contain active ingredients while others contain contaminants that could harm health.

An analysis of Viagra seized by law enforcement agents revealed that a Hungarian sample contained amphetamine. In the UK, the “little blue pill” Viagra was colored with printer ink and contained caffeine and bulk lactose. Out of 370 alleged Viagra samples sold on the internet, seized by authorities, and then analyzed by the Dutch National Institute for Public Health, only 10 were genuine – the rest contained a variety of other drugs.

Fake drugs sold on the internet are profitable, and laws that apply in one country may not apply in another, making control of sales difficult. The World Health Organization views internet sales of drugs as a community health hazard that needs to be stopped. Jackson explains that “obstacles to effective action include the lack of a clear worldwide consensus on what constitutes a counterfeit drug and the fact that activities that are illegal in one country may be legal in another.”

The study authors say clinicians should warn the public of the potential harm that can ensue from buying counterfeit drugs on the internet. In some cases selling fake drugs on the internet for erectile dysfunction and other health condition can be ten times as profitable per kilogram as heroin for unscrupulous marketers. The sale of counterfeit drugs can also lead people to avoid need health care, leaving conditions such as hypertension and diabetes undiagnosed.

Erectile Dysfunction Drug Review - Which Drugs Work the Best?


Erectile dysfunction is a medical term that sends men into a limp, no pun intended. It refers to the inability of a man to get an erection in the face of sexual intercourse, regardless of the desire and intention to engage in sexual activity and the presence of sexual stimulation. Erectile dysfunction is a threat to any romantic affairs or marriage; the absence of sexual intercourse builds up the frustration of the man and his partner, resulting in a strained relationship. Moreover, erectile dysfunction causes a man to lose his self-esteem and self-confidence. It is without a doubt that erectile dysfunction must be cured. This article gives an erectile dysfunction drug review and looks into the general effectiveness of drugs in treating erectile dysfunction.

There are many drugs that promise deliverance from the damaging clutches of erectile dysfunction. The most common of these drugs is Viagra, so this is the first product to be discussed in this erectile dysfunction drug review. Viagra is the brand or specific name of sildenafil, a medication that has the power to produce an erection, if taken at the right dose. Viagra comes as a pill. When the pill is swallowed, the sildenafil nitrate enters the man's bloodstream and then attaches to the PDE5 enzyme in the penis where most of the chemical is released. When the man becomes sexually stimulated or aroused, his brain sends the message to the NANC cells found in his penis. The nitrate oxide produced in the penis then creates cGMP, which works to relax the arteries in the penis. Because the PDE5 has been released, the cGMP in the penis builds up, allowing the arteries in the penis to dilate fully. The penis inflates with blood and, thanks be to Science, the man gets a complete erection. Viagra enjoys an 85% success rate, but all cases, whether successful or not, report side effects.

There is rarely an erectile dysfunction drug review that gives Viagra a failing grade. However, it is a must to learn about the side effects it brings. Firstly, Viagra tends to have a spill-over effect. As Viagra blocks PDE5, it touches PDE6, the enzyme used in the cone cells in the eye's retina. Many men who are patrons of Viagra report a change in the way they perceive the colors green and blue. Because of this disturbance in color vision, pilots are prohibited from taking Viagra 12 hours (or less) before a flight. In general, men are advised to take Viagra at least an hour before sexual intercourse. Secondly, Viagra poses a problem to men who are taking drugs such as nitroglycerin for heart problems, particularly angina. Nitroglycerin is a drug that increases nitric oxide and opens up the arteries for better supplication of oxygen into the heart. When nitroglycerin and Viagra are taken together, the highly increased amount of nitric oxide and the blocking of the PDE5 enzyme can result in more heart problems. In fact, there have been cases of heart attack, stroke, and death.

There are many other drugs that work the same way as Viagra does, and they also pose the same health risks. Common side effects include headaches, migraines, an upset stomach, and facial hotness or flushing. There is also the risk of getting a long-lasting erection, referred to medically as priapism, which can be painful and can permanently damage the tissues in the penis when left untreated. These drugs may also produce an allergic reaction. Viagra is a prescription drug primarily because of its serious nature. Any reliable erectile dysfunction drug review will say that it is best to consult a doctor and seek expert advice on the options available for treating erectile dysfunction. Furthermore, with so many drugs claiming to cure erectile dysfunction, it's only right to read not just one erectile dysfunction drug review but many others to find out which drugs work best.
