Prescribing CIALIS

CIALIS 5 mg, 10 mg, and 20 mg have been approved in the United States for as-needed treatment of ED since November 2003. With the approval of a low-dose daily treatment option of CIALIS (2.5 mg and 5 mg), you can provide an option to your patients who may be looking for a dosing option that can be taken without regard to timing of sexual activity.

With CIALIS, you can give your patients a choice
In consultation with their patients, physicians now have the freedom to choose the dosing regimen that is appropriate for them. Some men may prefer the up to 36 hours of efficacy provided by CIALIS for use as needed, while CIALIS for once daily use may be appropriate for men with ED who anticipate more frequent sexual activity (e.g., twice weekly).
