What is Cialis 20mg (Tadalafil)?

Cialis 20mg contains tadalafil, a PDE5 inhibitor used to treat erectile dysfunction (ED). It helps increase blood flow so you can achieve and maintain an erection when sexually stimulated. This 20mg strength is typically used on-demand before anticipated sexual activity.

How Cialis Works (PDE5 Inhibition)

Tadalafil blocks phosphodiesterase type-5 (PDE5). During sexual stimulation, this supports higher cyclic GMP levels in penile tissue, helping smooth muscle relaxation and improving blood flow to support an erection.

Who is Cialis 20mg Suitable For?

• Adult men (18+) with ED who are assessed as suitable during an online consultation.
• Men who prefer a longer-lasting ED option with a wider timing window.
• Patients whose prescriber confirms 20mg is appropriate based on history, medicines, and risk factors.

Who Should NOT Take Cialis 20mg

• If you take nitrates (e.g., GTN spray/tablets; isosorbide) or riociguat.
• If you have been advised to avoid sexual activity due to heart problems.
• If you’ve had a recent heart attack or stroke, have unstable angina, severe heart failure, or very low/unstable blood pressure (clinician review required).
• If you have severe liver disease, severe kidney problems, certain hereditary eye conditions, or a known allergy to tadalafil.

Dosage & Directions

On-demand dose (20mg)

• Take 1 tablet about 30 to 60 minutes before sexual activity.

• Typically starts working in 30 to 60 minutes (varies).
• May remain effective for up to 36 hours (varies).

Food & alcohol advice

Warnings & Interactions

Nitrates and poppers (contraindicated)

Never combine tadalafil with nitrates (for chest pain) or recreational ‘poppers’. This can cause a dangerous drop in blood pressure.

Alpha-blockers and blood pressure medicines

If you take alpha-blockers (e.g., doxazosin, tamsulosin) or other blood pressure medicines, you may need dose timing guidance or monitoring. Follow your prescriber’s instructions.

Other interactions
