Looking to get a Cialis prescription online in the EU? You can. An EU-licensed doctor reviews your case for just €35.

This article explains how Cialis interacts with blood pressure medication and how Hi-Doctor makes getting your medication safe and convenient.

How it works: get your Cialis prescription in 4 steps

  2. A licensed EU doctor reviews your case in private.
  3. If appropriate, you receive a valid electronic prescription within 24 hours.

Who qualifies for Cialis

When you seek a Cialis prescription online, the doctor looks for specific criteria to ensure your safety and treatment effectiveness. Cialis (tadalafil) is primarily for erectile dysfunction (ED) and benign prostatic hyperplasia (BPH). You must be an adult male. Key factors the doctor considers include your medical history, current medications, and overall health status. Conditions like severe heart disease, recent stroke, or uncontrolled high blood pressure are often contraindications. You must also disclose all medications, especially any nitrates or alpha-blockers, as these have significant interactions with Cialis.

What Cialis actually does (and doesn't do)

Cialis belongs to a class of drugs called PDE5 inhibitors. It works by increasing blood flow to the penis, which helps you achieve and maintain an erection when sexually stimulated. Its effect can last up to 36 hours, earning it the nickname 'the weekend pill'. For BPH, Cialis helps relax muscles in the prostate and bladder, easing urinary symptoms. It does not provide immediate erections without sexual stimulation, nor is it a cure for ED or BPH. It manages the symptoms effectively. It's important to have realistic expectations about its action and duration.

Side effects and when to stop

Like all medications, Cialis can cause side effects. Common ones include headache, indigestion, back pain, muscle aches, flushing, and stuffy or runny nose. These usually subside within a few hours. More serious, but rare, side effects include sudden vision loss, sudden hearing decrease or loss, or an erection lasting longer than 4 hours (priapism). If you experience any severe side effects or an erection lasting too long, seek immediate medical attention. Always stop taking Cialis and consult a doctor if you notice any concerning symptoms.
