Yes, many men can safely take Cialis every day at 70 — but only under medical supervision. Age alone does not automatically disqualify someone from daily Cialis use. In fact, clinical studies have included men well into their 70s and even 80s. Your healthcare provider may recommend limiting or avoiding grapefruit while taking tadalafil.
