What Is Tadalafil 20mg?
Tadalafil is a phosphodiesterase type-5 (PDE-5) inhibitor used to manage erectile dysfunction. The 20mg strength is typically prescribed when lower doses are insufficient or when stronger on-demand support is required. It improves blood flow to penile tissue during sexual stimulation.
How Tadalafil Works
Tadalafil inhibits the PDE-5 enzyme, increasing nitric oxide activity and relaxing smooth muscle in penile blood vessels. This enhances blood flow during sexual stimulation, supporting a firm erection.
Onset and Duration of Action
Tadalafil 20mg generally begins working within 30 minutes. Its effects can last up to 36 hours, offering greater flexibility compared to shorter-acting ED tablets.
Who Can Take Tadalafil 20mg?
Suitable for adult men diagnosed with erectile dysfunction following clinical assessment. A UK prescriber will review your medical history and current medicines before issuing a prescription.
Dosage and Administration
Recommended Dose
Take one 20mg tablet at least 30 minutes before sexual activity. Do not exceed one dose within 24 hours unless advised by your prescriber.
How to Take
Swallow the tablet whole with water. It can be taken with or without food. Heavy or high-fat meals may delay onset. Moderate alcohol consumption is acceptable, but excessive intake may reduce effectiveness.
Warnings, Contraindications and Interactions
Do not take tadalafil if you use nitrate medicines or riociguat, as this may cause dangerous drops in blood pressure. Use caution with alpha-blockers and strong CYP3A4 inhibitors. Not suitable for individuals with recent heart attack, stroke, severe cardiovascular disease, or certain retinal disorders. Seek urgent medical attention for chest pain, sudden vision or hearing loss, or erections lasting more than 4 hours (priapism).
