How it works — get your ED medication prescription in 4 steps
- Fill the online medical questionnaire (2–3 minutes) and pay the €25 consultation fee. This provides the doctor with all the necessary information to assess your case.
- A licensed EU doctor reviews your case in private. Our EU-licensed doctors evaluate your medical history and current health. If the doctor determines the treatment is not appropriate for you, your €25 is refunded automatically — you pay nothing.
- If approved, you receive a REMPE electronic prescription (PDF file) in your Hi-Doctor account and by email within 24 hours. This is Spain's official digital private prescription, recognised EU-wide.
- Print the PDF or show it on your phone — present it at any pharmacy in the EU to collect the medication. Your REMPE prescription is valid at any pharmacy in Spain, Portugal, Italy, France, Germany, Netherlands, Belgium, Austria, Ireland, and other EU countries.
Who qualifies for erectile dysfunction medication
Our EU-licensed doctors assess each case individually. They look for specific criteria to ensure the medication is safe and effective for you. Generally, you may qualify if you experience consistent difficulty achieving or maintaining an erection firm enough for sexual intercourse. The doctor will consider your overall health, including:
- Medical history: Conditions like heart disease, high blood pressure, diabetes, or liver/kidney problems are crucial.
- Current medications: Certain drugs, especially nitrates, can interact dangerously with ED medications.
- Allergies: Any known allergies to sildenafil, tadalafil, or similar compounds.
- Physical examination (implied by questionnaire): Symptoms and general health status.
Contraindications include severe heart or liver problems, recent stroke or heart attack, low blood pressure, or certain eye conditions. The doctor will determine if the treatment is appropriate and safe for your specific situation.
What erectile dysfunction medication actually does (and doesn't do)
Erectile dysfunction (ED) medications like sildenafil (Viagra) and tadalafil (Cialis) are known as PDE5 inhibitors. They work by increasing blood flow to the penis, which helps you achieve and maintain an erection when you are sexually stimulated. They do not cause an erection on their own; sexual arousal is still necessary.
What they do:
- Improve blood flow to the penis.
- Help achieve and maintain an erection when aroused.
- Offer a reliable solution for many men with ED.
What they don't do:
- Increase libido or sexual desire.
- Cure the underlying cause of ED (though they treat the symptoms).
- Protect against sexually transmitted infections.
- Work without sexual stimulation.
Realistic timelines vary, but most medications take effect within 30-60 minutes and last for several hours. Tadalafil, for example, can be effective for up to 36 hours.
Side effects and when to stop
Like all medications, ED treatments can cause side effects. Most are mild and temporary. Common side effects include:
- Headache
- Flushing (redness of the face)
- Nasal congestion
- Indigestion
- Back pain (more common with tadalafil)
When to stop and seek immediate medical attention (red flags):
- An erection lasting longer than 4 hours (priapism).
- Sudden vision loss or blurred vision.
- Sudden hearing loss or ringing in the ears.
- Chest pain or severe dizziness.
- Severe allergic reaction (rash, swelling, difficulty breathing).
Always discuss any concerns with your doctor and follow their instructions carefully. Medical honesty builds trust and ensures your safety.
