Cialis (Tadalafil) is used to treat male sexual function problems (impotence or erectile dysfunction-ED). In combination with sexual stimulation, tadalafil works by increasing blood flow to the penis to help a man get and keep an erection.
Tadalafil is also used to treat the symptoms of an enlarged prostate (benign prostatic hyperplasia-BPH). It helps to relieve symptoms of BPH such as difficulty in beginning the flow of urine, weak stream, and the need to urinate frequently or urgently (including during the middle of the night). Tadalafil is thought to work by relaxing the smooth muscle in the prostate and bladder.
This drug does not protect against sexually transmitted diseases (such as HIV, hepatitis B, gonorrhea, syphilis). Practice "safe sex" such as using latex condoms. Consult your doctor or pharmacist for more details.

WHAT'S THE DIFFERENCE BETWEEN CIALIS AND VIAGRA?
Cialis and Viagra are both PDE5 inhibitors used for the treatment of erectile dysfunction (ED). Both only work when a man is sexually aroused. Cialis lasts for around 36 hours compared with only 4 to 5 hours for Viagra. Food does not affect the activity of Cialis, whereas food may decrease the effectiveness of Viagra. Cialis can be used once daily, at a smaller dosage, and is also effective at treating benign prostatic hyperplasia (BPH). Dosage of Cialis may need to be reduced in men with liver or kidney problems and risk of interactions may be higher than with Viagra.
HOW TO USE CIALIS
Read the Patient Information Leaflet provided by your pharmacist before you start taking tadalafil and each time you get a refill. If you have any questions, ask your doctor or pharmacist.
The dosage is based on your medical condition, response to treatment, and other medications you may be taking. Be sure to tell your doctor and pharmacist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products).
To treat the symptoms of BPH, take this medication as directed by your doctor, usually once a day. If you are also taking finasteride with this medication to treat symptoms of BPH, talk with your doctor about how long you should continue taking this medication.
To treat erectile dysfunction-ED, there are 2 ways that tadalafil may be prescribed. Your doctor will determine which is the best way for you to take tadalafil. Follow your doctor's directions exactly since your dosage depends on how you are taking it. The first way is to take it as needed, usually at least 30 minutes before sexual activity. Tadalafil's effect on sexual ability may last up to 36 hours.
The second way to treat ED is to take tadalafil regularly, once a day every day. If you take it this way, you may attempt sexual activity at any time between your doses.
If you are taking tadalafil to treat both ED and BPH, take it as directed by your doctor, usually once a day. You may attempt sexual activity at any time between your doses.
If you are taking tadalafil once daily for BPH, or for ED, or for both, take it regularly to get the most benefit from it. To help you remember, take it at the same time each day.
