How long does it take to work?

The on-demand dose acts in 30–60 minutes. The low daily dose (typically 5 mg) reaches steady state in a few days and allows sexual activity without planning.

Who does tadalafil suit better than sildenafil?

Those seeking more spontaneity, or those who respond better to sustained action. It is also considered in cases with lower urinary tract symptoms (BPH), where tadalafil is indicated.

What are the common side effects?

Mild back pain, muscle ache, headache and facial flushing. Usually transient. Any visual disturbance or prolonged erection (>4 h) requires immediate medical attention.

Can I get a consultation for Tadalafil from Alicante?

Yes. Hi-Doctor runs 100 % online across the EU, so if you live in Alicante you can fill in the questionnaire and receive the medical review without travelling. The electronic prescription issued by the licensed doctor is valid in any EU pharmacy under Directive 2011/24/EU; in Spain it is dispensed directly from the prescription QR.

Is my sexual health consultation fully confidential?

Yes. All communication happens in the private chat of your account, GDPR-compliant. The doctor treats discretion as a core of the service and there is no history visible outside your consultation.

What is the private electronic prescription and why is it valid across the EU?

The private electronic prescription (Receta Médica Privada Electrónica) is issued by a licensed doctor in Spain. It is a PDF carrying every field required by EU Directive 2011/24/EU (patient, prescriber with country of registration, active ingredient, dose), which makes it legally recognised across all 27 EU member states. In Spanish pharmacies it is dispensed from the QR; outside Spain, the pharmacist dispenses the locally marketed equivalent of the same active ingredient.

How does Hi-Doctor work step by step?

1) Fill in an online medical questionnaire in about 4 minutes. 2) An EU-licensed doctor reviews your case and replies in under 24 h through the private chat in your account. 3) If eligible, the doctor issues an electronic prescription. 4) You collect it at any EU pharmacy. The consultation costs €25 and, if the doctor decides it is not safe to prescribe, the full amount is refunded.

How much does it cost and what does the price include?

The medical consultation costs €25 and includes a licensed doctor's review of your case and, if approved, the electronic prescription. If the doctor decides the treatment is not appropriate, the €25 is refunded. The medication price is separate and paid at the pharmacy; it varies by country, pharmacy and product across the EU. Because your electronic prescription is valid at any EU pharmacy, you can compare and choose where to fill it.

About

What is Tadalafil?

Active ingredient: Tadalafil · Dosages: 10 / 20 mg on demand · 5 mg daily

Tadalafil is a PDE5 inhibitor whose long half-life sets it apart — up to 36 hours of therapeutic window. That allows spontaneity, and a low-dose daily regimen is available for continuous use when clinically appropriate.

It also suits people who respond better to sustained action, and it's considered in cases with lower urinary tract symptoms (BPH), where tadalafil is indicated. The doctor weighs the on-demand versus daily approach with you.

How it works in the body

Like other PDE5 inhibitors it improves blood flow in response to stimulation — but its effect persists far longer. The on-demand dose acts in 30–60 minutes; the low daily dose reaches a steady effect in a few days.

How it helps

How it helps.

The 36-hour window

One on-demand dose covers a much longer period than other PDE5s.

Daily option

A low daily dose allows sexual activity without planning, when appropriate.

Doctor-screened

Cardiovascular health and interactions are reviewed before any prescription.

What to expect

How to take it.

Your schedule is personal

These are typical steps only. Your doctor adjusts the plan to how you respond and tolerate it — and you can message them at any point.

Safety first

Safety, in full.

Tadalafil is an effective medicine — and like any medicine it carries risks. Your doctor screens for all of this before prescribing. Here's the honest picture, not just reassurance.

Prescribed for adult men with erectile dysfunction in two regimens.

On-demand: 10 mg taken at least 30 minutes before sexual activity. Adjustable to 20 mg or 5 mg by the doctor.
Daily low-dose: 2.5 mg or 5 mg once a day for men with frequent activity or co-existing benign prostatic hyperplasia (BPH).
Effect window of up to 36 hours from a single dose; food and alcohol have minimal impact compared with sildenafil.

Who should not take it

Any nitrate medicine or amyl-nitrite recreational drug (“poppers”) — life-threatening blood-pressure drops.
Riociguat or any guanylate-cyclase stimulator.
Recent heart attack, stroke or unstable angina in the last 6 months.
Severe liver impairment, severe low or uncontrolled high blood pressure.
Hereditary degenerative retinal disorders or prior NAION.

When to seek urgent care

For severe, sudden or unexpected symptoms, call your local emergency number or go to the nearest emergency department. Then let your doctor know through your account chat.
