What is Cialis (Tadalafil)?
Cialis is a brand-name erectile dysfunction treatment containing tadalafil. Tadalafil supports the natural erection process by improving blood flow during sexual stimulation. It does not cause an automatic erection without arousal.
Who is Cialis 10mg for?
- Adult men (18+) who have difficulty achieving or maintaining an erection.
- Men who want a longer-lasting ED option with a wider timing window.
- Only for people who pass the suitability check during an online consultation.
How Cialis Works
Tadalafil relaxes blood vessels and improves blood flow to penile tissue during sexual arousal. This helps you achieve and maintain an erection when sexually stimulated.
Directions for Use (How to Take Cialis 10mg)
| Dose (typical) | When to take | Max use | Key notes |
| 10mg (1 tablet) | At least 30 minutes before sex | No more than 1 tablet in 24 hours | A large meal may slow onset; stimulation required. |
What to expect
- Onset: from around 30 minutes for many men (varies).
- Duration: may remain effective up to 36 hours (varies).
- This does not mean an erection lasts 36 hours; it means erections may be easier to achieve during that window when aroused.
