Erectile Dysfunction Medication: What Happens When You Stop?

Looking to get erectile dysfunction medication online in Spain or elsewhere in the EU? You've come to the right place. Hi-Doctor connects you with EU-licensed doctors who can review your case online and, if appropriate, issue a prescription for erectile dysfunction medication. This means no clinic visits, no waiting rooms, just a straightforward process. For a flat €35 consultation fee, you could have a valid prescription in under 24 hours, ready to be picked up at any pharmacy in the EU.

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

  1. Fill the online medical questionnaire (2–3 minutes) and pay the €35 consultation fee.
  2. A licensed EU doctor reviews your case in private. If the doctor determines the treatment is not appropriate, your €35 is refunded automatically, so there is no risk.
  3. If approved, you receive a valid electronic prescription (PDF file) in your Hi-Doctor account and by 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 the medication.

Who qualifies for erectile dysfunction medication

When an EU-licensed doctor reviews your case, they look for several factors to ensure erectile dysfunction medication is safe and appropriate for you. This typically involves assessing your general health, medical history, and any existing conditions. Common criteria include:

  • A confirmed diagnosis of erectile dysfunction.
  • Absence of severe cardiovascular issues, uncontrolled high blood pressure, or recent heart attack/stroke.
  • No history of certain eye conditions or kidney/liver disease that would contraindicate the medication.
  • Not currently taking nitrates or alpha-blockers, which can interact dangerously with ED medications.

The doctor will consider all information provided in your medical questionnaire to make an informed decision, always prioritising your safety.

What erectile dysfunction medication actually does (and doesn't do)

Erectile dysfunction medications, such as sildenafil (Viagra) and tadalafil (Cialis), belong to a class called PDE5 inhibitors. They work by increasing blood flow to the penis when you are sexually stimulated, making it easier to achieve and maintain an erection. They do not increase sex drive or cause an erection automatically without stimulation.

These medications offer temporary relief for erectile dysfunction; they do not cure the underlying causes. Their effects typically last for several hours (e.g., 4-6 hours for sildenafil, up to 36 hours for tadalafil). You take them as needed before sexual activity. It's important to understand that if you stop taking these medications, the symptoms of erectile dysfunction will likely return, as the root causes remain unaddressed.

Side effects and when to stop

Like all medications, erectile dysfunction treatments can have side effects. Common ones include headaches, flushing, indigestion, nasal congestion, and dizziness. More serious, but rare, side effects can include sudden vision loss or hearing loss, and an erection lasting longer than four hours (priapism), which requires immediate medical attention.

You should stop taking erectile dysfunction medication and seek urgent medical advice if you experience any severe side effects, chest pain, or a prolonged erection. Always consult with your doctor before discontinuing any prescribed medication, especially if you have underlying health conditions. Your Hi-Doctor EU-licensed doctor will discuss potential side effects and contraindications with you during your online consultation.
