Sildenafil, marketed under names like Viagra, is a recognized medication for treating erectile dysfunction. Available in various dosages, Sildenafil 25 mg represents the lowest dose. But how does this dosage work, and how long do its effects last? Let's explore these questions in detail.

What is Sildenafil 25 mg?

Le Sildenafil 25 mg appartient à une classe de médicaments appelés inhibiteurs de la phosphodiestérase de type 5 (PDE5). Ces médicaments agissent en augmentant le flux sanguin vers le pénis, facilitant ainsi l'obtention et le maintien d'une érection en réponse à une stimulation sexuelle.

This particular dosage is often recommended for men who are just starting treatment or those sensitive to the side effects of higher doses (50 mg or 100 mg). As an initial dose, it allows for a gentler approach tailored to each individual.

Mechanism of action of Sildenafil 25 mg

Sildenafil works by inhibiting the PDE5 enzyme, which plays a role in reducing an erection. Here's how it works:

  1. Smooth muscle relaxation: Sildenafil promotes the production of nitric oxide in the body, which causes the smooth muscles of the blood vessels in the penis to relax.
  2. Improvement of blood circulation: This relaxation allows a greater blood flow into the cavernous bodies of the penis, which is essential for a firm erection.
  3. Need for sexual stimulation: Contrary to some myths, Sildenafil does not automatically cause an erection. Sexual stimulation is essential for the drug to be effective.

Duration of action of Sildenafil 25 mg

Sildenafil starts to work between 30 minutes and one hour after ingestion. To optimize its effect, it is advised to take it on an empty stomach or after a light meal, as a fatty meal can delay its action.

  • Average duration of effect: Generally, the effects of Sildenafil 25 mg last about 4 to 6 hours. This means that a man has a comfortable period to respond to sexual stimulation.
  • Factors influencing duration: Factors such as age, overall health, alcohol consumption, or the use of other medications can extend or shorten this duration of effect.

Why choose Sildenafil 25 mg?

The 25 mg dosage is suitable for several specific situations:

  • Increased drug sensitivity: Men with a higher sensitivity to side effects such as headaches or flushing may benefit from a reduced dose.
  • Maintenance therapy: For men who need minimal support to maintain an erection, 25 mg may be sufficient.
  • Special populations: Men with preexisting health issues, such as mild renal or hepatic insufficiency, may start with this dosage under medical supervision.

How to take Sildenafil 25 mg?

To ensure the medication is effective and safe, follow these tips:

  1. Follow the medical prescription : Never take more than one dose in 24 hours.
  2. Do not combine it with nitrates: These medications, often prescribed for heart problems, can cause a dangerous drop in blood pressure when combined with Sildenafil.
  3. Moderate alcohol consumption: Excessive drinking can reduce the effectiveness of the medication.

Possible side effects

Although Sildenafil 25 mg is generally well tolerated, some side effects may occur:

  • Mild and transient effects: Headache, hot flashes, mild nausea, or nasal congestion.
  • Less common effects: Temporary visual disturbances or muscle pains.
  • Serious side effects (rare): If you experience chest pain, prolonged erection, or sudden loss of vision, seek medical attention immediately.

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.
