Which is better Cialis or Viagra?

Neither Cialis nor Viagra is universally better. Both are effective PDE-5 inhibitors for treating erectile dysfunction, and the choice depends on individual preference, lifestyle, and tolerability rather than overall effectiveness.

Cialis (tadalafil) has a longer duration of action, lasting up to 36 hours, which can allow greater flexibility and spontaneity. Viagra (sildenafil) has a shorter duration of around 4–6 hours. Both medications usually begin to work within 30–60 minutes and require sexual stimulation to be effective.

Key points:

Cialis can remain effective for up to 36 hours, offering a wider window for sexual activity.
Viagra typically works for 4–6 hours.
Onset for both medicines is usually 30–60 minutes; neither is consistently faster than the other.
Both have comparable effectiveness and similar side effects, such as headache, flushing, and indigestion.
Cialis is available as a daily low-dose option as well as on-demand dosing; Viagra is typically taken as needed.
