Erectile Dysfunction Medication Safety: What You Need to Know

Dealing with erectile dysfunction (ED) is common, and effective treatments like sildenafil (Viagra) and tadalafil (Cialis) are available. If you're looking to get an erectile dysfunction medication prescription online from an EU-licensed doctor, you've come to the right place. Hi-Doctor provides a convenient and private way to access treatment. For a flat fee of €35, an EU-licensed doctor reviews your case. If treatment is appropriate, you receive a digital prescription in under 24 hours, valid at any pharmacy in the EU. There's no risk — if the doctor determines the treatment is not suitable for you, your €35 consultation fee is refunded.

How it works: get your ED 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 decides 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 ED medication

When you complete your medical questionnaire, an EU-licensed doctor reviews your information to determine if ED medication is safe and appropriate for you. The doctor looks for several key factors, including your overall health, existing medical conditions, and current medications. Conditions like severe heart disease, uncontrolled high blood pressure, or certain liver or kidney issues may mean ED medication is not suitable. Your doctor will carefully assess these details to ensure your safety and the effectiveness of the treatment.

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

ED medications, such as sildenafil (Viagra) and tadalafil (Cialis), are part of a class called phosphodiesterase-5 (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. These medications do not cause an erection on their own; sexual stimulation is still necessary. They are effective for most men with ED, but they are not a cure for underlying causes of erectile dysfunction. You should expect the medication to help you achieve an erection during sexual activity, typically within 30-60 minutes for sildenafil, with effects lasting several hours. Tadalafil can last up to 36 hours.

Side effects and when to stop

Like all medications, ED drugs can have side effects. Common ones are usually mild and temporary, including headache, flushing of the face, nasal congestion, or indigestion. Less common but more serious side effects can include sudden changes in vision or hearing, or an erection lasting longer than four hours (priapism). If you experience any severe or concerning side effects, stop taking the medication immediately and seek medical attention. Your Hi-Doctor physician will discuss potential side effects with you during your consultation and advise on when to stop treatment.
