What's the difference between Viagra and Vyagra?
Viagra is a proven and safe prescription drug. Vyagra is similar to Viagra but is a dangerous, illegal unsupervised supplement. Learn why good control is essential.
What is Viagra?
Viagra is a registered medicine for the treatment of erectile dysfunction. Viagra has been proven effective and approved by the Dutch CBG and the European EMA. The active substance in Viagra is sildenafill, which improves blood flow in the penis and thus helps to get and maintain an erection. Viagra is a brand name and is also available as a generic sildenafil.
Viagra should only be dispensed with a doctor's prescription. So you can't get Viagra at the pharmacy without a prescription. For example, the doctor will check which dose suits your situation.
What is Vyagra and the difference with Viagra?
Vyagra sounds almost the same, but it is not an official medicine. It is an illegal food supplement. Vyagra is illegal because it contains unspecified active substances, often in dangerously high doses. Previously, Vyagra was even available via bol.com, but after an investigation by the Algemeen Dagblad, this dangerous sale was curbed.
Vyagra's big problem? You never know exactly what's in it. Doses may be far too high, or they may contain harmful substances. This is because there is no supervision of production, so there is no guarantee of quality and safety.
A recent report by the AD also explicitly warns against these types of “natural” erection pills. Researchers found these pills “full of chemicals, so strong that they scare me” (well). The use of these drugs can lead to serious side effects, such as heart problems, high blood pressure, or even dangerous interactions with other medications.
Why is good control so important?
Your health is the most important thing. When you consult a doctor and opt for an official treatment with Viagra, it will be checked whether the medicine is suitable and safe for you. At Fellos, this is done entirely online and discreetly, with an assessment by a Dutch doctor. You will then receive your medication via an authorized Dutch pharmacy; delivered reliably, safely and discreetly.
This way, you are assured of treatment that suits your situation and you avoid the risks of unsafe, illegal alternatives such as Vyagra.
