Sildenafil (Viagra) and Tadalafil (Cialis) both treat erectile dysfunction, but they differ significantly in their action and duration.
Sildenafil acts faster, generally taking effect within 30-60 minutes, but its effects last for about 4-5 hours. Cialis, on the other hand, takes longer to work (30-60 minutes, potentially longer on first use), yet its effects can last up to 36 hours, earning it the nickname “the weekend pill”.
Both medications work by increasing blood flow to the penis. However, they achieve this through slightly different mechanisms involving specific phosphodiesterase enzymes. This difference contributes to their varying durations of action.
The choice between Sildenafil 100mg and Cialis 100mg depends on individual needs and preferences. Men needing quicker onset of action may prefer Sildenafil. Those seeking longer-lasting effects might choose Cialis. Dosage adjustments may be necessary depending on individual response and physician guidance. Always consult a doctor before using either medication.
Consider potential side effects. Common side effects for both include headache, flushing, nasal congestion, and indigestion. Rarely, more serious side effects can occur. A doctor can help assess risks and benefits.
In summary, Sildenafil offers rapid but shorter-lasting effects, while Cialis provides longer-lasting effects but with a slower onset. Individual responses vary, making consultation with a healthcare professional vital for determining the best choice.
