Viagra® is undoubtedly the most well-known medication for treating erectile dysfunction. Since its market release in 1998, it has revolutionized the treatment of erectile dysfunction with its active ingredient, Sildenafil. However, while its effectiveness is well documented, purchasing this medication without a prescription on the internet poses numerous risks. Here is a complete guide to better understand how Viagra works, its side effects, and why it is essential to obtain it through a medical prescription.
Viagra works by inhibiting a specific enzyme, phosphodiesterase type 5, present in the penis. This enzyme plays a role in regulating blood flow. When Viagra is taken, it allows the smooth muscles of the penis to relax, thus facilitating the influx of blood into the cavernous bodies and the shaft, which leads to an erection. However, the drug does not work alone: sensory stimulation is necessary to provoke an erection.
Viagra is usually taken 30 to 60 minutes before sexual intercourse and its effects can last up to 5 hours. For optimal results, it is advised to take it on an empty stomach, as food can delay its absorption. The dosage of Viagra depends on many factors: lifestyle, weight, medical history, etc. Therefore, it is essential to consult a doctor to get a suitable prescription.
Viagra, despite its effectiveness, is not without risk. Indeed, it acts directly on blood flow and can lead to various side effects. The most common include headaches, dizziness, vision disorders, facial flushing, digestive problems, and a stuffy nose. More rarely, it can cause discomfort, nosebleeds, hearing loss, palpitations, or even heart rhythm disorders.
Moreover, Viagra is contraindicated in several situations. It should not be used in case of serious cardiovascular problems, or with nitrate medications (especially used for heart diseases) and certain recreational substances like poppers, as this can cause a dangerous drop in blood pressure. It is also not recommended for people with a history of cerebrovascular accidents, liver failure, or those suffering from vision impairments.
For these reasons, Viagra can only be dispensed with a prescription. Only a doctor can assess if the treatment is suitable, and adjust the dosage according to your overall health condition.
Buying Viagra without a prescription on the internet may seem tempting, especially when the embarrassment of discussing erectile dysfunction or the cost of a medical consultation are barriers. However, this practice carries significant risks. Viagra is one of the most counterfeited drugs in the world. Each year, Operation Pangea, conducted by Interpol and dozens of countries, seizes millions of fake medication tablets, a large portion of which are Viagra and Cialis.
These counterfeits can be not only ineffective but also extremely dangerous to health. In 2010, the Swiss Institute of Therapeutic Products analyzed 120 samples of fake drugs for erectile dysfunction. The results were alarming: some tablets were overdosed by up to 180%, increasing the risk of serious adverse effects. Others contained no active ingredient, but undeclared or toxic substances, such as heavy metals or ink.
To avoid the risks associated with counterfeit drugs, it is imperative to obtain Viagra through a medical prescription. This prescription can be acquired during a consultation with your primary care physician or through certified online platforms, such as Kano. These sites offer remote consultations with doctors, who can assess your situation and issue a prescription if necessary.
By obtaining Viagra legally, you are assured that the medication is safe and suitable for your condition. Moreover, medical follow-up allows for the adjustment of the treatment if necessary, and to prevent any adverse effects or drug interactions.
In conclusion, although Viagra is an effective treatment for erectile dysfunction, it should always be used under the supervision of a healthcare professional. Do not put your health at risk by purchasing this medication from uncertified sites. Each situation is unique and requires a personalized medical evaluation to ensure your safety and well-being.
