Tadalafil is a medication that is taken before sexual activity and allows men with erectile dysfunction (ED) to achieve and maintain an erection. ED or impotence is a condition in which a man is unable to achieve or maintain an erection long enough for sexual intercourse. This can be a result of medical conditions such as high blood pressure, diabetes, prostate problems, and heart disease, or a side effect of the medications typically taken for these conditions. Personal lifestyle factors such as stress, alcohol and/or tobacco use can also play a contributing role. During surgery or radiation to the pelvic area (including prostate, bladder, and rectal procedures), damage can occur to the nerves that supply the penis. This can result in either temporary or permanent impotence. Some surgeons perform "nerve-sparing" surgeries in an attempt to preserve erectile function. Even in these cases, however, the nerves will suffer some injury, and it can take 18-24 months or longer for erectile function to return. These men should be treated aggressively with oral or injectable medications for ED in order to speed recovery of the nerves and to prevent muscle wasting in the penis.
There are a number of things you can do to manage the side effects of Tadalafil. Talk to your doctor or nurse about these recommendations. They can help you decide what will work best for you. These are some of the most common side effects:
Headache, facial flushing and upset stomach can occur. Some patients experience back pain or muscle aches that typically occur 12 to 24 hours after taking tadalafil. This typically resolves on its own after 48 hours. If you have pain that persists, contact your doctor. Rarely, patients may have side effects including blurry vision, a bluish hue to the field of vision, a sensitivity to light, or a sudden loss of vision.
If you experience any of the following while using tadalafil, you should seek immediate medical attention:
Do not take a higher dose of tadalafil than your doctor orders for you. Remember, tadalafil does not protect against sexually transmitted diseases, nor does it prevent pregnancy.
