Viagra®, Cialis®, and Levitra® are three of the most popular medications for treating erectile dysfunction (ED), a common disorder in men of all ages. These drugs belong to the same class, that of type 5 phosphodiesterase inhibitors (PDE5), which work by increasing blood flow to the penis during sexual stimulation. Although they share this basic mechanism, Viagra® and Cialis® have distinct characteristics that may influence your choice depending on your needs. Viagra®, whose active ingredient is sildenafil, was the first drug on the market to treat ED. It is taken about 30 to 60 minutes before sexual activity, with an effect that lasts between 4 to 6 hours. It is particularly recommended for men who are looking for a short-term solution or who prefer to take medication on an as-needed basis. However, its relatively short duration of action may limit the spontaneity of sexual encounters. Cialis®, d

Difficulties in achieving or maintaining an erection are more common than one might think, affecting about 64% of men at some point in their lives, according to an IFOP survey.

Why can't I get an erection?

Experiencing difficulties in achieving or maintaining an erection is a frustrating and common experience, affecting 64% of men according to an IFOP study. These disorders can have various causes: from physiological factors such as cardiovascular or neurological diseases, to psychological causes such as anxiety, depression, or performance fear. Poor lifestyle habits, such as the consumption of alcohol, tobacco, or drugs, can also be responsible. Fortunately, treatments are available, including medications like Viagra®, Cialis®, or Levitra®, which promote blood flow to the penis and improve erectile function.

This article provides a detailed guide on the four main drugs used to treat erectile dysfunction: Viagra® (sildenafil), Cialis® (tadalafil), Levitra® (vardenafil), and Spedra® (avanafil). These medications, known as type 5 phosphodiesterase inhibitors (PDE5 inhibitors), block an enzyme responsible for the breakdown of a chemical messenger essential to erection, thus promoting the relaxation of the penis muscles and increasing blood flow. Viagra®, available since 1998, is taken about 30 minutes to an hour before sexual intercourse, with an effectiveness of 4 to 5 hours. Its dosage varies between 25 and 100 mg, depending on individual needs. Side effects include nausea, hot flashes, nasal congestion, and digestive disorders. It is contraindicated in patients taking nitrate vasodilators or anti-HIV treatments. Cialis®, introduced in 2003, has a dual utility. It can be taken occasionally, similar to Viagra®, or daily for a continuous effect, facilitating erection up to 36 hours after taking it. This treatment is suitable for men who have frequent sexual intercourse. Side effects are similar to those of Viagra®, but daily intake can prolong them. Levitra® and Spedra® also work in a similar way, with comparable durations of action and side effects. Levitra®, introduced in 2003, has an effectiveness of about 5 hours, while Spedra®, launched in 2013, is known for its rapid action, in less than 30 minutes. The article emphasizes the importance of medical consultation to determine the dosage and assess potential risks. Generic versions of PDE5 inhibitors offer more economical options without compromising effectiveness. Erectile dysfunction can be a sign of more serious health problems, and these medications should not be taken lightly. A medical prescription and a thorough evaluation by a healthcare professional are essential for safe and appropriate use.

Viagra is a well-known medication for treating erectile dysfunction thanks to its active ingredient, Sildenafil. By acting on the smooth muscles of the penis, it promotes blood flow and helps achieve an erection. Effective in 75% of cases, it is taken 30 to 60 minutes before sexual intercourse and its effect lasts up to 5 hours. However, this medication is only available by prescription. This is due to its possible side effects, such as headaches, dizziness, or vision problems. More seriously, there are contraindications, especially in the case of heart problems or interactions with certain medications, such as vasodilators. Viagra should be taken with caution and under medical supervision, as it affects blood flow and can cause complications. Purchasing Viagra without a prescription on the internet is not only illegal but also dangerous. Indeed, counterfeits are circulating, containing harmful substances or incorrect dosages. Each year, millions of fake tablets are seized, and 40% of them involve Viagra and Cialis. Some contain dangerous products, heavy metals, or undeclared substances. Others, overdosed by up to 180%, increase the risk of serious side effects. To avoid these dangers, it is crucial to obtain Viagra through a prescription issued by a doctor, either in a physical consultation or online on accredited sites like Kano. This ensures that the medication is suitable for your condition and avoids the risks associated with fake products. Each case is unique and should be considered by a professional. In conclusion, although Viagra is an effective solution for erectile dysfunction, it must always be used under medical supervision to ensure your safety and health.

How to get Viagra®?

Viagra®, used to treat erectile dysfunction, is a well-known molecule but also one of the most counterfeited in the world. Its effectiveness, proven by numerous studies, is based on Sildenafil, which promotes blood flow to the penis. However, it is only available by prescription due to possible side effects and contraindications, such as heart problems or interactions with certain medications. Buying Viagra without a prescription online is risky: many fake tablets contain dangerous substances. It is essential to consult a doctor to get a prescription and ensure your safety.
