What Is Cenforce and Why Does Dosage Matter?.
Cenforce is a prescription-strength sildenafil medicine designed to improve blood flow during sexual activity. You can learn more about how sildenafil behaves over time in our guide How Long Does Sildenafil Last?
Even though Cenforce 100mg and 200mg work through the same mechanism, dosage affects intensity and duration. A higher dose does not always mean better results. Choosing the right strength depends on ED severity, tolerance, age and your doctor’s assessment.

How Sildenafil Works in Your Body
Sildenafil relaxes blood vessels and increases circulation to the penis. It requires natural sexual stimulation to work. All Cenforce strengths follow the same biological pathway; only the intensity changes with dosage.
How Quickly It Starts Working
Most men experience results within 30 to 60 minutes. If you want detailed insights into absorption speed, see our article How Food, Alcohol, and Lifestyle Affect Sildenafil Effectiveness.
Heavy meals and alcohol may slow the effect. Consistency helps ensure more predictable results.

When Doctors Consider Cenforce 200mg

- Men who have tried Cenforce 100mg several times with insufficient effect.
- Men with severe erectile dysfunction.
