What Is Cialis?

Cialis is a prescription medication used to treat erectile dysfunction (ED) and symptoms of an enlarged prostate (BPH). Its active ingredient, tadalafil, helps increase blood flow to specific areas of the body, particularly the penis.
Unlike Viagra, Cialis can be taken daily or as needed, making it flexible for different lifestyles. Many men prefer Cialis because of its long-lasting effects, sometimes up to 36 hours. This has earned it the nickname, "the weekend pill."
If you’re new to ED treatment, understanding how Cialis works and whether it's right for you is the first step to better sexual performance and confidence.

How Does Cialis Work in the Body?
Tadalafil, the main compound in Cialis, is a PDE5 inhibitor. PDE5 is an enzyme that restricts blood flow by tightening blood vessels. Cialis blocks PDE5, allowing blood vessels to relax and expand.
With relaxed blood vessels, more blood can flow into the penis during sexual stimulation. This helps achieve and maintain a firm erection.
Key Points:
-
Takes effect in about 30 to 60 minutes
-
Lasts up to 36 hours
-
Doesn’t cause automatic arousal; sexual stimulation is still needed
Cialis can be taken daily in low doses (2.5mg or 5mg) or as needed in higher doses (10mg or 20mg). Always follow your doctor’s dosage recommendations.

Cialis Benefits for Sexual Performance

Cialis isn't just for treating ED. It can enhance your overall sexual experience in several ways:
-
Longer window of effectiveness: No need to time your dose with your partner.
-
Boosts sexual confidence: Knowing you're ready anytime can reduce anxiety.

Treats BPH symptoms: Helps reduce urinary urgency and frequency.
Because of its long duration, many men feel more relaxed and focused on intimacy instead of worrying about timing their medication.
