That’s why Tadalafil was invented and being approved by USA Food and Drug Administration in 2003.

Meccanismo del Tadalafil

• It acts at erectile tissue inside the penis

Domande frequenti

Q1: How does Tadalafil work for erectile dysfunction?

Tadalafil is a PDE5 inhibitor that works by preserving nitric oxide (NO) in the erectile tissue of the penis. When sexual arousal occurs, brain signals travel to the penile tissue, and Tadalafil helps the erectile tissue respond more readily, making it easier to achieve and maintain an erection. It does not cause spontaneous erections — sexual stimulation is still required.

Q2: How long does Tadalafil last compared to Sildenafil (Viagra)?

Tadalafil has a significantly longer duration of action at up to 36 hours, compared to Sildenafil which lasts only 3-5 hours. This extended window gives couples more flexibility and spontaneity. Tadalafil can also be taken with fatty meals or alcohol without reducing its effectiveness, unlike Sildenafil which may be affected by food and alcohol intake.

Q3: What are the side effects of Tadalafil?

Common side effects of Tadalafil include headache (12%), dyspepsia or indigestion (7%), back pain (6%), and flushing (3%). These side effects are generally mild and temporary. Back pain is more commonly associated with Tadalafil than with other PDE5 inhibitors and typically resolves within 48 hours without treatment.

Q4: Who should NOT take Tadalafil?

Tadalafil is contraindicated in men taking nitrate medications (used for chest pain such as sublingual nitroglycerin), as the combination can cause a dangerous drop in blood pressure. It should also be avoided in men with a recent history of stroke or heart attack, and in those with a known allergy to Tadalafil. Always consult a doctor before starting any ED medication.

Q5: Can I buy Tadalafil without a prescription?

While Tadalafil may be available over the counter in some countries, it is strongly recommended to consult a qualified urologist before use. Self-medicating with ED medications without proper evaluation risks missing an underlying cause of erectile dysfunction such as cardiovascular disease, hormonal imbalance, or diabetes. A urologist can confirm the diagnosis, assess safety, and prescribe the correct dosage.
