Taking tadalafil with a nitrate can cause a serious decrease in blood pressure, leading to fainting, stroke, or heart attack.

If you have any of the conditions like heart disease or heart rhythm problems; a recent heart attack (within the past 90 days); a recent history (within the past 6 months) of stroke or congestive heart failure; 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 bleeding disorder such as hemophilia; 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 been told you should not have sexual intercourse for health reasons you might need an adjustment in dose or special tests.

Tadalafil can decrease blood flow to the optic nerve of the eye, causing sudden vision loss. This has occurred in a small number of people taking tadalafil, most of whom also had 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. It is not clear whether tadalafil is the actual cause of vision loss. Stop using tadalafil and get emergency medical help if you have sudden vision loss.

It is not known whether tadalafil passes into breast milk or if it could harm a nursing baby. Do not use this medication without telling your doctor if you are breast-feeding a baby.
