Erectile Dysfunction: Medications and Natural Remedies

Are you looking for a Sildenafil prescription online in Spain or elsewhere in the EU? You can get a prescription for Sildenafil through an EU-licensed doctor, quickly and discreetly, without a clinic visit. Hi-Doctor.ai offers a €25 flat online consultation. If the doctor finds treatment appropriate, your REMPE electronic prescription is issued in under 24 hours and delivered to your private account and by email. This prescription is valid at ANY EU pharmacy, from Spain to Germany.

How it works — get your Sildenafil prescription in 4 steps

  1. Fill out a short online medical questionnaire (2–3 minutes).
  2. An EU-licensed doctor reviews your case in private.
  3. If the doctor finds it appropriate, you receive a REMPE electronic prescription within 24 hours.
  4. Pick up your medication at any EU pharmacy.

Who qualifies for Sildenafil

Our EU-licensed doctors individually review every case. They assess your medical history, current health status, and any other medications you are taking to determine if Sildenafil is a safe and appropriate treatment for you. Factors like cardiovascular health, blood pressure, and liver function are carefully considered. The doctor looks for contraindications that might make Sildenafil unsuitable, ensuring your safety is paramount.

What Sildenafil actually does (and doesn't do)

Sildenafil, commonly known by its brand name Viagra, belongs to a class of medications called PDE5 inhibitors. It works by increasing blood flow to the penis when you are sexually stimulated, making it easier to achieve and maintain an erection. It does not cause an erection automatically; sexual arousal is still required. Sildenafil typically starts working within 30 to 60 minutes and its effects can last for about 4 to 6 hours. It is not a cure for erectile dysfunction but effectively manages its symptoms, allowing for satisfactory sexual activity.

Side effects and when to stop

Like all medications, Sildenafil can cause side effects. Common side effects include headache, flushing, nasal congestion, indigestion, and temporary visual disturbances (such as a bluish tinge to vision). More serious, but rare, side effects include a sudden decrease or loss of vision or hearing, and an erection that lasts longer than 4 hours (priapism). If you experience any severe or prolonged side effects, you must stop taking Sildenafil and seek immediate medical attention. Always discuss any concerns with your doctor.
