Cialis is a prescription medicine used to treat erectile dysfunction (ED) in adult men. It helps improve erectile response by increasing blood flow to the penis. Cialis offers flexibility in dosing options, making it a reliable solution for many individuals facing difficulties with sexual performance. It may also be prescribed for benign prostatic hyperplasia (BPH) in some cases.
How It Works
Cialis contains the active ingredient tadalafil, a phosphodiesterase type 5 (PDE5) inhibitor. It works by blocking the enzyme that breaks down cyclic GMP, a chemical involved in the erection process. As a result, the smooth muscles in the blood vessels of the penis relax, allowing increased blood flow during sexual stimulation. This mechanism enhances the natural erectile response without altering sexual desire.
Why Choose Cialis
Cialis is known for its extended duration of action — up to 36 hours — giving users a wider window of opportunity compared to other erectile dysfunction treatments. It is available in both “as needed” and daily low-dose versions, offering greater flexibility depending on lifestyle and preference. The once-daily option provides continuous readiness, helping men feel more spontaneous and less pressured about timing.
Important Note
Cialis should only be taken under medical supervision. It must not be used by those taking nitrates or with severe cardiovascular conditions. Side effects such as headache, flushing, or indigestion are usually mild and short-lived. Seek medical attention for prolonged or painful erections lasting over 4 hours. Always inform your doctor of any other medications or health conditions before starting Cialis.
