Viagra (sildenafil) versus cialis, which is better and which lasts longer?

A doctor has provided 1 answer

They both: Work in the proper situation and when used appropriately. Make sure you need such an rx before taking. Viagra (sildenafil) lasts about 6-8 hours, and Cialis can las up to 36. Neither is "better"; they both do what they're supposed to do. Talk w/your doctor.
