Who qualifies for Sildenafil
Your Hi-Doctor EU-licensed doctor assesses your medical history and current health to determine if Sildenafil is right for you. They look for specific criteria, including:
- Medical conditions: The doctor will check for conditions like diabetes, heart disease, high blood pressure, or hormonal imbalances that might affect Sildenafil's safety or efficacy.
- Current medications: It's crucial to disclose all medications you're taking, especially nitrates for chest pain, as Sildenafil can have dangerous interactions.
- Overall health: Your doctor ensures there are no contraindications that would make Sildenafil unsafe.
This individual review ensures your treatment plan is safe and tailored to your specific needs.
What Sildenafil actually does (and doesn't do)
Sildenafil (the active ingredient in Viagra) is a phosphodiesterase-5 (PDE5) inhibitor. It works by increasing blood flow to the penis when you are sexually stimulated. This helps you achieve and maintain an erection firm enough for satisfactory sexual intercourse.
Here’s what Sildenafil does:
- Enhances natural response: It helps your body respond more effectively to sexual stimulation, facilitating an erection.
- Improves blood flow: By relaxing blood vessels in the penis, Sildenafil allows more blood to flow in.
What Sildenafil doesn't do:
- Cause automatic erections: You still need sexual stimulation for Sildenafil to work. It's not an aphrodisiac.
- Cure ED: Sildenafil treats the symptoms of erectile dysfunction, but it doesn't cure the underlying causes.
- Protect against STIs: It does not offer protection against sexually transmitted infections.
Most men experience improved erectile function within 30-60 minutes of taking Sildenafil. Its effects typically last for about 4–6 hours.
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 (redness and warmth in your face or chest)
- Nasal congestion
- Dizziness
- Mild visual disturbances (e.g., blurred vision, sensitivity to light)
- Indigestion
More serious side effects are rare, but you should seek immediate medical attention if you experience:
- A sudden decrease or loss of vision or hearing.
- Priapism (a prolonged and painful erection lasting more than 4 hours).
- Symptoms of a heart attack or stroke (e.g., chest pain, shortness of breath, weakness on one side of your body).
Always discuss your full medical history with your Hi-Doctor EU-licensed doctor to ensure Sildenafil is safe for you, especially if you have heart conditions or take other medications.
