A:

The Cialis dosage for ED (erectile dysfunction) can be once daily every day or only as needed. Cialis will reach peak concentrations in about two hours. If you use Cialis as needed, make sure it has enough time to work. Take Cialis at least two hours before sex. You can expect the effects to last up to 36 hours.
