Do not take Cialis if you are also using a nitrate drug for chest pain or heart problems. This includes nitroglycerin (Nitrostat, Nitrolingual, Nitro-Dur, Nitro-Bid, and others), isosorbide dinitrate (Dilatrate-SR, Isordil, Sorbitrate), and isosorbide mononitrate (Imdur, ISMO, Monoket). Nitrates are also found in some recreational drugs such as amyl nitrate or nitrite (”poppers”). Taking Cialis with a nitrate medicine can cause a serious decrease in blood pressure, leading to fainting, stroke, or heart attack.A small number of patients have had a sudden loss of eyesight after taking Cialis. This type of vision loss is caused by decreased blood flow to the optic nerve of the eye. It is not clear whether Cialis is the actual cause of such vision loss. Sudden vision loss with Cialis use has occurred most often in people with heart disease, diabetes, high blood pressure, high cholesterol, or certain pre-existing eye problems, and in those who smoke or are over 50 years old.
Before taking Cialis, tell your doctor if you have:
- heart disease or heart rhythm problems;
- a recent history a heart attack (within the past 90 days);

- angina (chest pain);
- high or low blood pressure;
- liver disease;
- kidney disease (or if you are on dialysis);
- a blood cell disorder such as sickle cell anemia, multiple myeloma, or leukemia;

- a stomach ulcer;
- retinitis pigmentosa (an inherited condition of the eye);
- a physical deformity of the penis (such as Peyronie’s disease); or

If you have any of these conditions, you may not be able to use Cialis or you may need a dosage adjustment or special tests during treatment.
