Short answer: Sildenafil is the active ingredient in medications like Viagra, prescribed for erectile problems. It requires a prescription in the Netherlands. Buying sildenafil without a prescription is risky due to counterfeit products and unknown dosages. Discuss erectile issues with a doctor.
Sildenafil is the substance behind the most well-known erectile dysfunction treatments. Anyone researching the topic will frequently encounter the name, regardless of brand names like Viagra or the unregistered Kamagra. On this page, you will learn what sildenafil is, why it is only available by prescription, and which responsible options exist.
What is sildenafil?
Sildenafil is an active ingredient that belongs to the group of PDE5 inhibitors. These substances widen blood vessels and temporarily improve blood flow. During sexual arousal, this can support an erection. Sildenafil is found in the branded medicine Viagra and in generic versions, and it is the same substance offered in the unregistered Kamagra.
The substance does not work automatically or independently of arousal. It facilitates a natural response but does not trigger it. It is a medication, not a lifestyle product.
Prescription requirement and why
In the Netherlands, sildenafil is prescription-only. This is entirely due to safety reasons. The substance affects blood vessels and blood pressure and can have dangerous interactions with other medications, especially nitrates used for heart conditions. Caution is also necessary with certain cardiovascular diseases.
A doctor therefore first assesses your health and medication use before prescribing sildenafil. This assessment is the protection you miss out on when purchasing it outside the regular channels.
Risks without a prescription
Buying sildenafil without a prescription means purchasing outside quality control. Research into such products regularly reveals counterfeits: incorrect or varying amounts of active ingredient, contaminants, or substances that should not be present. Additionally, without a prescription assessment, you have no insight into interactions with your own medication. Unknown quality, unknown dosage, and no guidance: the risks add up.
Natural support
For those who want to responsibly support blood flow and libido, there are dietary supplements that support the body. They do not work immediately and are not medications but provide nutrients that play a role in natural processes. See our comparison of natural erection pills for this. You can read more about the branded medicines on our pages about Viagra and Kamagra.
When to see a doctor?
For persistent erectile problems, the general practitioner is the wisest first step. Not only to get a safe, appropriate medication prescribed but also because the complaint may have an underlying cause that deserves attention.
