How is it used?

Follow your doctor's instructions exactly how to take CIALIS. Consult your doctor or pharmacist if you have any doubts.

CIALIS taken daily may be useful in men who plan to be sexually active two or more times a week. The recommended dose is one 5 mg tablet once a day at about the same time of day. Your doctor may adjust the dose to 2.5 mg depending on your response to CIALIS. CIALIS tablets are taken by mouth. Swallow the tablet whole with a little water. You can take CIALIS with or without food.

CIALIS taken daily allows you to obtain an erection, at any time, 24 hours a day, as long as there is sexual stimulation. It is important to note that CIALIS is not effective without sexual stimulation. Therefore, you and your partner should stimulate yourselves in the same way you would if you were not taking an erectile dysfunction medicine.

Drinking alcohol can affect your ability to have an erection. Drinking alcohol may temporarily lower your blood pressure. If you have taken or are planning to take CIALIS, avoid excessive alcohol consumption (blood alcohol level of 0.08% or higher), as it may increase the risk of dizziness when standing up.

You should not take CIALIS more than once a day.
