Who qualifies for Sildenafil

Our EU-licensed doctors carefully assess each case to ensure Sildenafil is safe and effective for you. They look for specific criteria:

  • You must be an adult male experiencing erectile dysfunction.
  • No known allergies to Sildenafil or similar medications.
  • No severe cardiovascular conditions, uncontrolled high blood pressure, or recent heart attack/stroke.
  • You must not be taking nitrate medications (e.g., nitroglycerin) for chest pain, as this can lead to a dangerous drop in blood pressure.
  • No severe liver or kidney disease.
  • No history of non-arteritic anterior ischemic optic neuropathy (NAION), a condition causing vision loss.

The doctor considers your full medical history and current medications to determine if Sildenafil is the right choice for you.

What Sildenafil actually does (and doesn't do)

Sildenafil, commonly known as Viagra, treats erectile dysfunction by increasing blood flow to the penis. It's a PDE5 inhibitor, meaning it helps relax the blood vessels in the penis when you are sexually aroused. This allows more blood to flow in, helping you achieve and maintain an erection.

It does NOT work automatically. Sildenafil requires sexual stimulation to be effective. It does not create an erection on its own. Typically, you take Sildenafil 30–60 minutes before sexual activity. Its effects usually last for 4–6 hours, providing a window of opportunity for intimacy. Factors like food intake (especially high-fat meals) can delay its onset. Remember, Sildenafil helps with the physical aspect of an erection; it doesn't address underlying psychological causes of ED.

Side effects and when to stop

Like all medications, Sildenafil can cause side effects. Most are mild and temporary, such as headache, flushing, nasal congestion, and visual disturbances (e.g., blurred vision, increased light sensitivity). If these occur, they usually subside as your body adjusts or the medication wears off.

However, some side effects are serious and require immediate medical attention:

  • An erection lasting longer than 4 hours (priapism).
  • Sudden vision loss in one or both eyes.
  • Sudden decrease or loss of hearing.
  • Chest pain, dizziness, or nausea during sexual activity.

Always inform your doctor of all medications you are taking, including over-the-counter drugs and supplements, as Sildenafil can interact dangerously with certain substances, particularly nitrates.
