Tadarise 10 mg is not necessarily stronger than Cenforce 25 mg or Fildena 120 mg. They contain different doses of medicines, so milligram amounts cannot be compared directly. Product Active ingredient Typical duration Tadarise 10 mg Tadalafil Up to 36 hours Cenforce 25 mg Sildenafil About Tadarise 10 mg Sildenafil About 4 hours; 120 mg exceeds the usual recommended maximum Which lasts longer? Tadalafil (Tadarise) generally lasts longer than sildenafil (Cenforce or Fildena). Which is stronger? That depends on your response, side effects, health conditions and prescribed dose. Tadalafil's longer duration does not automatically mean a stronger erection. Do not combine Tadarise with Cenforce or Fildena. Combining ED medicines can dangerously lower blood pressure. The usual maximum recommended sildenafil dose for ED is 100 mg in 24 hours.
