Who qualifies for Sildenafil
Our EU-licensed doctors follow strict medical guidelines to ensure your safety. When you apply for Sildenafil online, the doctor looks for several key factors:
- Your medical history: Conditions like heart problems, stroke, or kidney/liver disease are important.
- Current medications: Sildenafil interacts with certain drugs, especially nitrates. Always list all medications you're taking.
- Severity of erectile dysfunction: This helps determine if Sildenafil is the right treatment and what dosage might be suitable.
- Overall health: A general assessment ensures there are no contraindications.
The doctor's priority is your health. They will only issue a prescription if they find treatment appropriate for your specific situation.
What Sildenafil actually does (and doesn't do)
Sildenafil, widely known as Viagra, treats erectile dysfunction (ED) by increasing blood flow to the penis. It works by inhibiting an enzyme called PDE5, which allows the smooth muscles in the penis to relax and blood vessels to widen during sexual stimulation. This helps you achieve and maintain an erection firm enough for sexual activity.
Important points:
- Sildenafil requires sexual stimulation to work. It does not automatically cause an erection.
- It typically takes 30-60 minutes to start working, and its effects can last up to 4 hours.
- Sildenafil does not protect against sexually transmitted infections.
- It does not increase sexual desire.
Understanding how Sildenafil works helps set realistic expectations and ensures you use it effectively.
Side effects and when to stop
Like all medications, Sildenafil can cause side effects. Most are mild and temporary. Common side effects include headache, flushing, nasal congestion, indigestion, and visual disturbances (such as blurred vision or a blue tint). These usually subside as your body adjusts.
Seek immediate medical attention if you experience:
- An erection lasting longer than 4 hours (priapism).
- Sudden decrease or loss of vision.
- Sudden decrease or loss of hearing.
- Symptoms of a severe allergic reaction (rash, swelling, severe dizziness, trouble breathing).
Always inform your doctor about any side effects you experience. If you have any concerns or experience serious side effects, stop taking Sildenafil and contact your doctor immediately.
