Who qualifies for Tadalafil
When you seek a Tadalafil prescription EU wide, the doctor evaluates your medical history to ensure Tadalafil is safe and appropriate. They look for specific criteria, including your overall health, existing conditions, and current medications. Tadalafil is generally prescribed for erectile dysfunction (ED) and sometimes for benign prostatic hyperplasia (BPH).
Contraindications include:
A private sexual-health consultation.
An EU-licensed doctor reviews your case through a private chat inside your account, no waiting room, no WhatsApp. €35, reply within 24 h.
- Use of nitrate drugs (e.g., for chest pain), as this can cause a dangerous drop in blood pressure.
- Certain heart conditions or recent heart attack/stroke.
- Severe liver or kidney problems.
- Certain eye conditions.
- Uncontrolled high or low blood pressure.
Always disclose your full medical history and all medications you are currently taking during your online consultation. This allows the doctor to make an informed decision and ensure your safety.
What Tadalafil actually does (and doesn't do)
Tadalafil, known by the brand name Cialis, is a phosphodiesterase-5 (PDE5) inhibitor. It works by increasing blood flow to the penis during sexual stimulation, helping you achieve and maintain an erection. It does not create sexual arousal; stimulation is still required for it to be effective. Tadalafil is also used to treat symptoms of benign prostatic hyperplasia (enlarged prostate) and pulmonary arterial hypertension.
One key benefit of Tadalafil is its long duration of action, up to 36 hours, which is why it's often called the 'weekend pill.' This allows for greater spontaneity compared to other ED medications. It typically starts working within 30-60 minutes.
Tadalafil does not protect against sexually transmitted infections (STIs) and is not a contraceptive.
Side effects and when to stop
Like all medications, Tadalafil can cause side effects. Most are mild and temporary. Common side effects include:
- Headache
- Flushing (warmth, redness, or tingly feeling)
- Nasal congestion or runny nose
- Muscle aches or back pain
- Indigestion or heartburn
These usually subside as your body adjusts. However, some side effects are serious and require immediate medical attention. Stop taking Tadalafil and seek help if you experience:
- Sudden vision changes or loss of vision.
- Sudden hearing decrease or loss, sometimes with ringing in the ears and dizziness.
- An erection lasting longer than 4 hours (priapism), which can cause permanent damage to the penis.
- Symptoms of an allergic reaction: rash, itching, swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.
- Chest pain, irregular heartbeat, or other heart-related symptoms.
Always follow your doctor's instructions and never exceed the prescribed dose.
