A member asked:

My dr gave me samples of cialis 20mg and a 30 day pack of 5mg daily use. could i take 4x 5mg pills to equal 20mg, when i run out of the single 20mgs?

A doctor has provided 1 answer

Cialis: For the most part, there is no difference between a single 20 mg tablets and four 5 mg tablets. You should consider that the lowest dose that gives you a sufficient erection, is the proper dose. You may not need the full 20 mg dose every time.
