Who qualifies for Viagra

When you seek a Viagra prescription online through Hi-Doctor, our EU-licensed doctors individually review your case. They look for several factors to determine if Viagra is safe and appropriate for you:

  • Medical History: The doctor assesses your overall health, including any existing heart conditions, blood pressure issues, or other chronic diseases.
  • Current Medications: You must disclose all medications you are currently taking, as some can interact dangerously with Viagra (e.g., nitrates).
  • Erectile Dysfunction Symptoms: You must have a diagnosis or symptoms consistent with Erectile Dysfunction (ED).
  • Contraindications: Certain conditions, like severe heart problems or recent stroke, make Viagra unsafe. The doctor screens for these.

Our EU-licensed doctors prioritize your safety. If they find the treatment appropriate, they issue your prescription.

What Viagra actually does (and doesn't do)

Viagra (sildenafil) is a highly effective medication for Erectile Dysfunction. It works by increasing blood flow to the penis, but only when you are sexually stimulated. Here’s a breakdown:

  • Mechanism: Viagra belongs to a class of drugs called PDE5 inhibitors. It helps relax the blood vessels in your penis, allowing more blood to flow in, leading to an erection.
  • Onset: You typically feel the effects within 30 to 60 minutes after taking it.
  • Duration: The effects can last for about 4 to 5 hours.
  • What it isn't: Viagra is not an aphrodisiac. It does not cause automatic erections and requires sexual arousal to work. It won't increase your libido or cure underlying causes of ED, though it effectively treats the symptom.

Understanding these points helps set realistic expectations for your treatment.

Side effects and when to stop

Like all medications, Viagra can cause side effects. Most are mild and temporary, but it's important to be aware of them:

  • Common Side Effects: Headache, flushing (redness or warmth in your face, neck, or chest), indigestion, nasal congestion, and changes in vision (e.g., blurred vision, sensitivity to light).
  • When to Seek Immediate Medical Attention (Red Flags):
    • 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 follow your doctor's instructions. If you experience severe side effects or persistent discomfort, stop taking Viagra and consult a medical professional immediately. Your Hi-Doctor EU-licensed doctor can provide guidance through the private, RGPD-compliant chat in your account.
