Cialis is an oral prescription pill used by men to treat erectile
dysfunction (ED). ED is also known as impotence or erection
problems.
Results may vary, but for some men, Cialis (tadalafil) often works
within 30 minutes and stays effective for up to 36 hours.
Do not take Cialis if you take any nitrates, which are often
prescribed to control chest pains. This combination could cause an
unsafe drop in blood pressure.
