  • 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. The active ingredient 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. Sexual activity can put an extra strain on your heart, especially if your heart is already weak from a heart attack or heart disease.

    What Should I Tell My Healthcare Provider Before Taking CIALIS?

    CIALIS is not right for everyone. Only your healthcare provider and you can decide if CIALIS is right for you. Ask your healthcare provider if your heart is healthy enough for you to have sexual activity. You should not take CIALIS if your healthcare provider has told you not to have sexual activity because of your health problems. Before taking CIALIS, tell your healthcare provider about all your medical problems, particularly if you have or ever had:

    • heart problems such as chest pain (angina), heart failure, irregular heartbeats, or have had a heart attack
    • high or low blood pressure or have high blood pressure that is not controlled
    • stroke
    • liver or kidney problems or require dialysis
    • retinitis pigmentosa, a rare genetic (runs in families) eye disease
    • severe vision loss, including a condition called NAION
    • stomach ulcers or a bleeding problem
    • a deformed penis shape or Peyronie's disease
    • an erection that lasted more than 4 hours
    • blood cell problems such as sickle cell anemia, multiple myeloma, or leukemia

    Can Other Medicines Affect CIALIS?

    Tell your healthcare provider about all the medicines you take especially if you take:

    • medicines called "nitrates" which are often prescribed for chest pain
    • alpha-blockers often prescribed for prostate problems
    • blood pressure medications
    • medicines for HIV or some types of oral antifunga

      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. Men 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 within 2 days. Call your healthcare provider if you get any side effect that bothers you or one that does not go away.

      Uncommon but serious side effects include:
      An erection that won't go away: If you get an erection lasting more than 4 hours, seek immediate medical help to avoid long-term injury.

      In rare instances, men taking prescription ED tablets, including CIALIS, reported a sudden decrease or loss of vision or hearing (sometimes with ringing in the ears and dizziness). It's not possible to determine if these events are related directly to the ED tablets or to other factors. If you have a sudden decrease or loss of vision or hearing, stop taking any ED tablet, including CIALIS and call a healthcare provider right away.
