Viagra® is a widely used medication for treating erectile dysfunction (ED), and it is often misunderstood regarding its actual effects on the penis. Its active ingredient, sildenafil, works by increasing blood flow to the penis during sexual stimulation. However, it is important to clarify that Viagra® does not increase penis size.

A safe and effective treatment for erectile dysfunction

Erectile dysfunction affects many men, and although it can sometimes be a taboo subject, there are effective medical solutions like Viagra. Available in various dosages (Viagra 25 mg, 50 mg, and 100 mg), this medication helps to treat erectile dysfunction by improving blood flow to the penis. Kano.care, a platform specializing in men's intimate health, allows consulting a doctor online and obtaining a prescription safely and discreetly for this treatment.

A quick glance at search engines is enough to understand: internet users search more for "pill to get hard", "tablet to get hard" or "viagra without prescription" than for medically validated solutions by urologists.

Discover in this article everything you need to know about prescription Viagra and the reasons to favor medical supervision over turning to risky alternatives.

How does Viagra work?

The active ingredient in Viagra is sildenafil, a type 5 phosphodiesterase inhibitor (PDE5) that allows the blood vessels to dilate in the penis. This process promotes a greater blood flow into the cavernous bodies, thus facilitating the achievement and maintenance of an erection. Viagra should be taken about one hour before sexual intercourse for optimal effectiveness. It is important to note that this medication only works if sexual stimulation is present, and its effect can last several hours.

Viagra is available in different dosages: 25 mg, 50 mg, and 100 mg. The choice of dosage will depend on the medical evaluation of your situation and your response to the treatment. A doctor, such as those consulted via Kano.care, will be able to prescribe the appropriate dose after considering several factors like overall health and the presence of underlying medical conditions, such as heart problems or hypertension.

The side effects of Viagra

Although Viagra is a safe medication when taken according to a prescription, it can cause certain side effects in some patients. The most common are:

  • Vision disorders (blurred vision or blue colorations),
  • Muscle pains,
  • Rashes,
  • Rapid heart rate,
  • Angina pectoris (chest pains).

If you experience any of these symptoms after taking Viagra, it is crucial to consult a primary care physician or a healthcare professional immediately. It is also essential to never exceed the dose prescribed by the doctor.

Who can take Viagra?

Viagra is indicated for men suffering from erectile dysfunction. However, it is not suitable for everyone. Certain medical conditions, such as a history of heart diseases, angina pectoris, or the use of nitrate-based medications, are significant contraindications. Viagra can also interact with other medications prescribed for treating conditions like high blood pressure or heart diseases. That's why it is essential to have a consultation with a doctor before any use.

Through Kano.care, a patient can obtain a comprehensive diagnosis to ensure that Viagra is the best option for them. Doctors specializing in teleconsultation make sure that the treatment is suitable and safe. In some cases, alternatives to Viagra may be suggested, such as other PDE5 inhibitors or non-drug solutions.

Why get Viagra through Kano.care?

  1. A secure and fast consultation Through the platform Kano.care, you can consult a doctor online, at any time, to discuss your erectile dysfunction issues. The teleconsultation is discreet, convenient, and avoids the drawbacks of a face-to-face consultation. After discussing your health condition and symptoms with a healthcare professional, if Viagra is deemed appropriate, a prescription will be issued to you.
  2. A secure prescription Buying Viagra online without a prescription is dangerous. Prescription medications, like Viagra, should be prescribed by a healthcare professional to ensure maximum safety. Kano.care offers a certified medical consultation service, ensuring that you get authentic and safe medications. If prescribed, a box of 8 tablets of Viagra will be shipped to you by a licensed pharmacy.
  3. The coverage of treatments Although Viagra is not reimbursed by health insurance in France, you can benefit from partial coverage if you have a health mutual that covers medications related to erectile dysfunction. It is important to check with your insurer the reimbursement conditions for this type of treatment.

Alternatives to Viagra

For some men, Viagra may not be the most suitable option. Fortunately, there are several Viagra alternatives available on prescription, such as Cialis (tadalafil) or Levitra (vardenafil). These medications work in a similar way by promoting the dilation of blood vessels, but have different durations of action and slightly different side effect profiles.

In consultation with a primary care physician through Kano.care, patients can explore these alternatives if Viagra does not meet their expectations or if they experience undesirable side effects.

Treatments for erectile dysfunction, such as Viagra®, Cialis®, Levitra®, and Spedra®, carry potential risks that vary depending on the patient's health condition. They may cause serious side effects, including cardiovascular issues, dangerous drug interactions, or prolonged erections (priapism), which require immediate medical attention. It is essential never to take these medications without the advice of a qualified healthcare professional. A thorough medical consultation is necessary to determine the appropriate treatment for each individual, taking into account medical history and contraindications. Additionally, it is crucial to ensure that the medications are obtained from reliable and authorized sources. Medications purchased outside legal channels or without a prescription may be counterfeit, ineffective, or even harmful to health. Always consult a doctor before using these treatments and obtain medications from a licensed pharmacy.
