In general, Cialis and Viagra should not be taken on the same day. There are special circumstances when specialists allow the use of both these drugs on the same day, but this is individualized treatment for a patient.
It is safe to take Cialis a day after taking Viagra, as Viagra has a short duration of action. However, Viagra can only be taken 48 hours after taking Cialis, as Cialis has a longer duration of action.
