Who qualifies for Tadalafil

Our EU-licensed doctors assess each case to ensure Tadalafil is safe and appropriate for you. They look for specific criteria, including your medical history and current health status. Tadalafil is typically prescribed for erectile dysfunction (ED) and benign prostatic hyperplasia (BPH). However, certain conditions or medications can make Tadalafil unsuitable. For instance, if you take nitrates for chest pain or alpha-blockers for high blood pressure, Tadalafil may not be an option. Always provide a complete and accurate medical history during your online consultation. The doctor will determine if Tadalafil is suitable for your long-term use.

What Tadalafil actually does (and doesn't do)

Tadalafil, the active ingredient in Cialis, belongs to a class of medications called PDE5 inhibitors. It works by relaxing the blood vessels in the penis, which increases blood flow when you're sexually stimulated. This makes it easier to achieve and maintain an erection. Tadalafil is known for its long-lasting effects, up to 36 hours, allowing for more spontaneity. It does not create an erection automatically; sexual stimulation is still required. Tadalafil does not cure ED; it manages the symptoms. It also won't increase your sexual desire or protect against sexually transmitted infections.

Side effects and when to stop

Like all medications, Tadalafil can cause side effects. Common side effects are usually mild and include headache, flushing, nasal congestion, back pain, muscle aches, and indigestion. These often subside as your body adjusts. More serious, but rare, side effects can occur. Seek immediate medical attention if you experience sudden vision loss, sudden hearing loss, or an erection lasting longer than 4 hours (priapism). Always follow your doctor's instructions and inform them if any side effects are severe or persistent. If you experience serious side effects, stop taking Tadalafil and consult a medical professional immediately.
