Who qualifies for Tadalafil

Our EU-licensed doctors carefully assess your medical history to ensure Tadalafil is safe and effective for you. They look for specific criteria, including a diagnosis of Erectile Dysfunction (ED) or Benign Prostatic Hyperplasia (BPH). Contraindications include, but are not limited to, certain heart conditions, uncontrolled high blood pressure, recent stroke or heart attack, and specific eye conditions. It is crucial to disclose all current medications, especially nitrates, as these can interact dangerously with Tadalafil. The doctor makes the final decision on whether treatment is appropriate for your individual health profile.

What Tadalafil actually does (and doesn't do)

Tadalafil, known by its brand name Cialis, is a PDE5 inhibitor. It works by increasing blood flow to the penis, helping you achieve and maintain an erection when you are sexually stimulated. It does not cause an instant erection or act as an aphrodisiac; sexual stimulation is still required. Tadalafil is famous for its long-lasting effect, often up to 36 hours, earning it the nickname "the weekend pill." This means you have a wider window of opportunity for sexual activity, offering more spontaneity compared to other ED medications. Remember, it does not mean a continuous erection for 36 hours, but rather that the drug remains active in your system, making it easier to achieve an erection with stimulation.

Side effects and when to stop

Like all medications, Tadalafil can have side effects. Common ones include headache, flushing, nasal congestion, back pain, and indigestion. These are usually mild and temporary. More serious, though rare, side effects include sudden vision loss, sudden hearing decrease, or an erection lasting longer than four hours (priapism). If you experience any severe side effects, seek immediate medical attention. Always inform your doctor about all your health conditions and medications during your online consultation to ensure Tadalafil is safe for you.
