Select Important Safety Information

Do not take CIALIS if you:

  • take medicine called "nitrates" such as isosorbide dinitrate or isosorbide mononitrate which are often prescribed for chest pain, or use recreational drugs called "poppers" like amyl or butyl nitrite, as the combination may cause an unsafe drop in blood pressure
  • are allergic to CIALIS or ADCIRCA® (tadalafil), or any of its ingredients. Call your healthcare provider or get help right away if you experience any symptoms of an allergic reaction, such as rash, hives, swelling of the lips, tongue or throat, or difficulty breathing or swallowing.

After taking a single tablet, some of the active ingredient of CIALIS remains in your body for more than 2 days. It can remain longer if you have problems with your kidneys or liver, or you are taking certain other medications.

Stop sexual activity and get medical help right away if you get symptoms such as chest pain, dizziness, or nausea during sex.

What Can Cause ED?

There are many things that can contribute to erectile dysfunction (ED)—from physical issues, like another health condition, to possible side effects of medicines that you're taking. Even emotional or personal issues can play a role. But for most men, ED can be treated, whether the cause is physical or psychological.

Possible physical conditions and other factors that can lead to ED include:

  • High blood pressure (also called hypertension)
    High blood pressure can damage blood vessels throughout the body, including those in the penis.
  • Diabetes (high blood sugar)
    Diabetes can increase the chances of having ED. Over time, high blood sugar can damage blood vessels and nerves in the penis.
  • High blood cholesterol
    Over time, high blood cholesterol can cause blood vessels throughout the body, including those in the penis, to narrow. If this happens, then not enough blood flows into the penis for a firm erection.
  • Nerve diseases
    Diseases that affect the nerves, such as Parkinson's disease and multiple sclerosis, can increase the chances of having ED. The penis may not receive nerve messages from the brain or spinal cord. And without the nerve messages, blood may not flow into the penis.
  • Surgery or injury (especially prostate, bladder, or rectal surgery)
    Surgery or injuries to the pelvic area can damage nerves or blood vessels leading to the penis.
  • Low hormone levels
    Low levels of male hormone (testosterone) may affect a man's ability to get an erection. ED can also happen when a man's thyroid hormone level is too high or too low.
  • Lifestyle factors
    Smoking, being overweight, drinking too much alcohol, not being physically active, or using recreational drugs can cause ED.
  • Side effect of medication
    ED can be a side effect of some medicines, including those that treat high blood pressure and antihistamines (like medicines that treat allergies). If you take one of these medicines and think it may be causing ED, don't stop taking it without first talking with your doctor.
  • Emotional or personal issues
    Less often, ED may be caused by emotional or personal issues—from ongoing stress or relationship problems to depression or anxiety about sexual performance.

If you think you have any of these conditions, be sure to talk to your doctor. Whatever the cause of your ED, only your doctor can determine if treatment is right for you.

ED can be an early warning sign of a serious health problem—heart disease, high blood pressure, or diabetes. Be sure to tell your doctor if you think you might have ED.
