How it works: get your erectile dysfunction medication prescription in 4 steps

  1. Fill out a brief online medical questionnaire (takes 2–3 minutes) and pay the €35 consultation fee.
  2. A licensed EU doctor individually reviews your case. If the doctor determines the treatment is not appropriate for you, your €35 fee is refunded automatically — no risk.
  3. If approved, you receive a valid electronic prescription (a secure PDF file) in your Hi-Doctor account and by email within 24 hours.
  4. Print the PDF or show it on your phone at any pharmacy in the EU to collect your medication.

Who qualifies for sildenafil or tadalafil

Our EU-licensed doctors look for several key factors to determine if sildenafil or tadalafil is appropriate for you. Generally, these medications are suitable for adult men experiencing erectile dysfunction. The doctor will assess your medical history for conditions such as heart disease, uncontrolled high blood pressure, liver or kidney problems, and any history of stroke or heart attack. They will also review your current medications, especially nitrates, for potential dangerous interactions. Your overall health and specific symptoms are crucial in their decision-making process to ensure your safety and treatment effectiveness.

What sildenafil or tadalafil actually does (and doesn't do)

Sildenafil (the active ingredient in Viagra) and tadalafil (the active ingredient in Cialis) are phosphodiesterase-5 (PDE5) inhibitors. They work by increasing blood flow to the penis when you are sexually stimulated, helping you achieve and maintain an erection firm enough for sexual activity. They do not increase libido or treat underlying psychological causes of ED. Sildenafil typically works within 30-60 minutes and lasts for about 4-5 hours, while tadalafil can be effective for up to 36 hours. Neither medication will cause an erection without sexual arousal.

Side effects and when to stop

Like all medications, sildenafil and tadalafil can cause side effects. Common ones include headaches, flushing, indigestion, nasal congestion, and dizziness. Less common but more serious side effects include sudden vision loss, sudden hearing loss, or an erection lasting more than 4 hours (priapism). If you experience any severe side effects, seek immediate medical attention. Always inform your doctor about all medications you are taking, especially nitrates, as combining them with ED drugs can cause a dangerous drop in blood pressure. If you feel unwell or experience unusual symptoms, stop the medication and consult your doctor.
