Erectile Dysfunction Medication: What the Studies Really Show

Are you looking for an erectile dysfunction medication prescription online in the EU? You've come to the right place. Hi-Doctor connects you with EU-licensed doctors who can review your case and, if appropriate, issue a digital prescription for ED medication. This means you can get the treatment you need quickly, discreetly, and without a clinic visit. Our online consultation costs just €35, and if the doctor determines the treatment is not suitable, you get your money back. If approved, you receive your prescription in under 24 hours, valid at any pharmacy across the EU.

How it works: get your ED medication prescription in 4 steps

  1. Fill out a brief online medical questionnaire (2–3 minutes) and pay the €35 consultation fee.
  2. An EU-licensed doctor reviews your case individually and privately. If the doctor determines the treatment is NOT appropriate for you, your €35 fee is refunded automatically — no risk, you pay nothing.
  3. If approved, you receive a valid electronic prescription (PDF file) in your Hi-Doctor account and via email within 24 hours.
  4. Print the PDF or show it on your phone and present it at any pharmacy in the EU to collect your medication.

Who qualifies for ED medication

Our EU-licensed doctors assess each patient individually to ensure safe and effective treatment. They look for specific criteria, including your overall health, medical history, and any existing conditions. Generally, ED medications like sildenafil (Viagra) and tadalafil (Cialis) are suitable for men experiencing difficulty achieving or maintaining an erection. However, certain health conditions, such as severe heart disease, uncontrolled high blood pressure, or a history of stroke, may be contraindications. The doctor will also consider medications you are currently taking, especially nitrates, which are incompatible with ED drugs. The online questionnaire helps the doctor understand your unique situation to determine if ED medication is appropriate and safe for you.

What ED medication actually does (and doesn't do)

Most oral ED medications, such as sildenafil and tadalafil, are Phosphodiesterase-5 (PDE5) inhibitors. They work by increasing blood flow to the penis when you are sexually aroused. During sexual stimulation, your body releases nitric oxide, which leads to the relaxation of smooth muscles in the penis, allowing more blood to flow in. PDE5 inhibitors prevent the breakdown of a chemical called cGMP, which is crucial for this muscle relaxation and increased blood flow. This helps you achieve and maintain a firm erection. It's important to understand that these medications do not create sexual desire; they only assist with the physical process of erection when you are already stimulated. They typically start working within 30-60 minutes and their effects can last from 4 to 36 hours, depending on the specific medication.

Side effects and when to stop

Like all medications, ED drugs can have side effects. Common side effects include headache, flushing, nasal congestion, indigestion, and temporary visual disturbances. More serious side effects are rare but can include a sudden decrease or loss of vision or hearing, or an erection lasting more than four hours (priapism). If you experience any severe or persistent side effects, you should stop taking the medication and seek immediate medical attention. Your Hi-Doctor will provide comprehensive information on potential side effects and interactions. Always follow your doctor's advice and report any unusual symptoms.
