Sildenafil works by inhibiting an enzyme called phosphodiesterase type 5 (PDE5), which promotes the relaxation of blood vessels and improves blood flow to the penis during sexual stimulation. This helps achieve and maintain an erection. However, Sildenafil does not cause spontaneous erections nor does it increase libido or sexual desire. Sexual stimulation is required for it to be effective.

The duration of action of Sildenafil is generally about 4 to 6 hours after intake. This means it remains effective during this period, enabling an erection in response to sexual stimulation. However, it does not cause a spontaneous erection but facilitates the natural process. The duration can vary depending on factors such as age, overall health, and the use of other medications.

The most common side effects of Sildenafil include headaches, facial flushing, digestive issues, muscle or back pain, and nasal congestion. These effects are generally mild and temporary, but it is advisable to consult a doctor if symptoms persist or worsen.

No, Sildenafil is not suitable for everyone. This medication, used to treat erectile dysfunction, can be taken by men in good general health, but medical advice is necessary to determine the appropriate dosage, which is why it is only available by prescription. Elderly individuals or those taking multiple medications require extra caution.

Although moderate alcohol consumption is generally safe with Sildenafil, excessive consumption can reduce its effectiveness and increase the risk of side effects such as dizziness, headaches, or a drop in blood pressure.

Sildenafil is typically prescribed to be taken as needed, about 30 minutes to one hour before sexual activity, and its effect usually lasts 4 to 6 hours. It is an oral tablet to be taken by mouth. It is very important to read the leaflet included in the medication box before using Sildenafil. Sildenafil is only available by prescription from a doctor. Only a doctor can determine the appropriate dosage for your specific situation.

As a non-reimbursed medication by social security in France, the price of Sildenafil is freely set and can therefore vary from one pharmacy to another. In France, a box of 4 tablets of Sildenafil 50 mg can cost between €8 and €40 approximately, depending on the brand and the type of tablet (film-coated or orodispersible). For example, the price of a box of 8 tablets of Sildenafil Biogaran 100 mg is around €10.
