What is CIALIS?
CIALIS is a prescription medicine taken by mouth for the treatment of erectile dysfunction (ED) in men. CIALIS (pronounced see-AL-iss) was shown to improve erectile function compared to placebo up to 36 hours following dosing. In clinical studies, the ability to have sexual activity was improved in some patients at 30 minutes after taking a dose.

ED is a condition where the penis does not harden and expand when a man is sexually excited, or when he cannot keep an erection. A man who has trouble getting or keeping an erection should see his doctor for help if the condition bothers him. CIALIS may help a man with ED get and keep an erection when he is sexually excited.

CIALIS does not:

  • cure ED
  • increase a man's sexual desire
  • protect a man or his partner from sexually transmitted diseases, including HIV. Speak to your doctor about ways to guard against sexually transmitted diseases.
  • serve as a male form of birth control
  • CIALIS is only for men with ED. CIALIS is not for women or children. CIALIS must be used only under a doctor's care.

How does CIALIS work?
When a man is sexually stimulated, his body's normal physical response is to increase blood flow to his penis. This results in an erection. CIALIS helps increase blood flow to the penis and may help men with ED get and keep an erection satisfactory for sexual activity. Once a man has completed sexual activity, blood flow to his penis decreases, and his erection goes away.

CIALIS was shown to be effective in men over the age of 18 years who have erectile dysfunction, including men with diabetes or who have undergone prostatectomy.

Talk to your doctor to see if CIALIS is right for you.

Do NOT take CIALIS if you:

  • Take any medicines called nitrates.
  • Take medicines called "alpha blockers", other than Flomax® 0.4mg once-daily.
  • Use recreational drugs called "poppers" like amyl nitrate and butyl nitrate.
  • You have been told by your healthcare provider to not have sexual activity because of health problems.
  • Take any medicines called nitrates. Nitrates are commonly used to treat angina. Angina is a symptom of heart disease and can cause pain in your chest, jaw, or down your arm.

Medicines called nitrates include nitroglycerin that is found in tablets, sprays, ointments, pastes, or patches. Nitrates can also be found in other medicines such as isosorbide dinitrate or isosorbide mononitrate. Some recreational drugs called "poppers" also contain nitrates, such as amyl nitrate and butyl nitrate. Do not use CIALIS if you are using these drugs. Ask your doctor or pharmacist if you are not sure if any of your medicines are nitrates.

Do NOT take CIALIS if you:

  • Take medicines called "alpha blockers", other than Flomax® 0.4 mg daily. Alpha blockers are sometimes prescribed for prostate problems or high blood pressure. If CIALIS is taken with alpha blockers other than Flomax? 0.4 mg daily, your blood pressure could suddenly drop to an unsafe level. You could get dizzy and faint.
  • You have been told by your healthcare provider to not have sexual activity because of health problems. Sexual activity can put an extra strain on your heart, especially if your heart is already weak from a heart attack or heart disease.
  • Are allergic to CIALIS or any of its ingredients. The active ingredient in CIALIS is called tadalafil.

What are the possible side effects of CIALIS?
The most common side effects with CIALIS are headache, indigestion, back pain, muscle aches, flushing, and stuffy or runny nose. These side effects usually go away after a few hours. Patients who get back pain and muscle aches usually get it 12 to 24 hours after taking CIALIS. Back pain and muscle aches usually go away by themselves within 48 hours. Call your doctor if you get a side effect that bothers you or one that will not go away.

CIALIS may uncommonly cause:

  • an erection that won't go away (priapism). If you get an erection that lasts more than 4 hours, get medical help right away. Priapism must be treated as soon as possible or lasting damage can happen to your penis including the inability to have erections.
  • vision changes, such as seeing a blue tinge to objects or having difficulty telling the difference between the colors blue and green. These are not all the side effects of CIALIS. For more information, ask your doctor or pharmacist.

Can other medications affect CIALIS? Tell your doctor about all the medicines you take including prescription and non?prescription medicines, vitamins, and herbal supplements. CIALIS and other medicines may affect each other. Always check with your doctor before starting or stopping any medicines. Especially tell your doctor if you take any of the following:

  • medicines called nitrates.
  • medicines called alpha blockers. These include Hytrin® (terazosin HCl), Flomax® (tamsulosin HCl),
  • Cardura® (doxazosin mesylate), Minipress® (prazosin HCl) or Uroxatral® (alfuzosin HCl).
  • ritonavir (Norvir®) or indinavir (Crixivan®)
  • ketoconazole or itraconazole (such as Nizoral® or Sporanox®)
  • erythromycin
  • other medicines or treatments for ED
  • General Information about CIALIS:

Medicines are sometimes prescribed for conditions other than those described in patient information leaflets. Do not use CIALIS for a condition for which it was not prescribed. Do not give CIALIS to other people, even if they have the same symptoms that you have. It may harm them.

CIALIS is not for everyone. Men taking any form of nitrates (often used to control anginal chest pain) should never take CIALIS, as the combination may cause an unsafe drop in blood pressure. Men taking medicines called "alpha blockers" (sometimes prescribed for prostate problems or high blood pressure), with exception of Flomax® (tamsulosin HCl) 0.4 mg once-daily, should not take CIALIS. This combination could cause a significant drop in blood pressure.

In clinical trials, the most common side effects with CIALIS were headache, upset stomach, backache, and muscle ache. Most men weren't bothered by the side effects enough to stop taking CIALIS. In placebo controlled Phase III clinical trials, discontinuation rates in patients treated with CIALIS 10 mg or 20 mg was 3.1%, compared to 1.4% in placebo treated patients.

Men should discuss their health status with their doctors to ensure CIALIS is right for them and that they are healthy enough to engage in sexual activity. CIALIS is not recommended in patients who have suffered a heart attack or stroke within the last 6 months, or patients who have significantly low blood pressure, uncontrolled high blood pressure, unstable angina, severe liver impairment, or retinitis pigmentosa (a rare eye disorder). CIALIS does not protect a man or his partner from sexually transmitted diseases (STDs), including HIV.
