Usually, Viagra is taken only as needed for sexual activity.
If you have questions about what your Cialis dosage should be, talk with your doctor. As ED treatments, both Cialis and Viagra can be taken occasionally (as needed) before sexual activity. The usual dosage for occasional Cialis use is one 10-mg tablet at least 30 minutes before anticipated sexual activity. The usual dosage for occasional Viagra use is one dose 1 hour before sexual activity. Cialis is also approved for once-daily dosing for ED, but Viagra is not.

In comparison, Viagra’s effects can last up to 4 hours. But on average, its effects start to reduce 2 to 3 hours after you take a dose. The typical dose for once-daily Cialis for ED is 2.5 milligrams (mg) to 5 mg. Cialis and Viagra both contain medications to treat ED.
