Looking to get a medication prescription online from an EU-licensed doctor? You've come to the right place. Hi-Doctor provides a fast, secure, and affordable way to access common treatments like GLP-1s for weight management, hair loss medications, and sexual health solutions. Our EU-licensed doctors review your case individually, issuing a valid electronic prescription in under 24 hours if appropriate. The best part? It's just €25, and your prescription is valid at any pharmacy across the EU.

How it works — get your medication prescription in 4 steps

  1. Fill your online medical questionnaire and pay the €25 consultation fee. This takes 2–3 minutes.
  2. An EU-licensed doctor reviews your case in private. If the doctor determines the treatment is NOT appropriate for you, your €25 fee is refunded automatically — you pay nothing.
  3. Receive your electronic prescription (PDF) within 24 hours. If approved, a REMPE electronic prescription (Spain's official digital-private-prescription standard) is issued and sent to your Hi-Doctor account and by email.
  4. Collect your medication at any EU pharmacy. Print the PDF or show it on your phone — present it at any pharmacy in the EU (Spain, Portugal, Italy, France, Germany, Netherlands, Belgium, Austria, Ireland, etc.) to collect your medication.

Who qualifies for the medication

Our EU-licensed doctors carefully assess each patient's medical history to ensure the chosen medication is safe and appropriate. Here's what the doctor looks for:

  • For GLP-1 medications (like semaglutide or tirzepatide for weight loss): Generally, you need a Body Mass Index (BMI) of 30 or higher, or a BMI of 27 or higher with at least one weight-related comorbidity (e.g., high blood pressure, type 2 diabetes, dyslipidemia). The doctor will also check for contraindications such as a personal or family history of medullary thyroid carcinoma or Multiple Endocrine Neoplasia syndrome type 2 (MEN 2), severe gastrointestinal disease, or pregnancy/breastfeeding.
  • For hair loss treatments (e.g., finasteride, dutasteride, minoxidil): The doctor assesses the pattern and extent of hair loss, looking for male pattern baldness (androgenic alopecia). They will consider your overall health and any existing medical conditions or medications that might interact.
  • For sexual health treatments (e.g., sildenafil, tadalafil): The doctor will evaluate the cause of erectile dysfunction, your cardiovascular health, and any medications you are currently taking, especially nitrates, which are a contraindication.

The doctor's review ensures your safety and the effectiveness of the treatment.

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

Understanding how your medication works helps set realistic expectations:

  • GLP-1s (e.g., semaglutide, tirzepatide): These medications mimic natural hormones that regulate appetite and blood sugar. They slow gastric emptying, making you feel fuller for longer, and reduce food cravings. This leads to reduced calorie intake and significant, sustained weight loss over several months. They are not 'magic pills' and work best when combined with lifestyle changes.
  • Hair Loss Treatments (e.g., finasteride, dutasteride): These medications work by blocking the conversion of testosterone to dihydrotestosterone (DHT), a hormone responsible for shrinking hair follicles in male pattern baldness. Minoxidil works by improving blood flow to hair follicles. Results typically appear after 3–6 months of consistent use, with full effects taking 9–12 months. They primarily prevent further hair loss and can stimulate regrowth, but they won't regrow hair on completely bald areas.
  • Sexual Health Treatments (e.g., sildenafil, tadalafil): These medications increase blood flow to the penis, helping men achieve and maintain an erection when sexually aroused. They do not cause spontaneous erections and require sexual stimulation to be effective. They treat the symptoms of erectile dysfunction but not its underlying causes.

Side effects and when to stop

All medications can have side effects. Our doctors will discuss these with you, but here are some common ones:

  • GLP-1s: Common side effects include nausea, vomiting, diarrhoea, constipation, and abdominal pain, especially when starting treatment or increasing the dose. These usually lessen over time. Stop and consult a doctor if you experience severe abdominal pain, signs of pancreatitis, or severe allergic reactions.
  • Hair Loss Treatments: Finasteride and dutasteride can cause sexual side effects (decreased libido, erectile dysfunction) in a small percentage of men. Minoxidil can cause scalp irritation. Stop if you experience severe allergic reactions or persistent, bothersome side effects.
  • Sexual Health Treatments: Common side effects include headache, flushing, nasal congestion, and indigestion. Rarely, more serious side effects like sudden vision or hearing loss, or an erection lasting more than 4 hours (priapism), can occur. Seek immediate medical attention if these happen.

Always follow your doctor's instructions and report any concerning side effects.
