Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
Rarely, a sudden loss of eyesight in one or both eyes (NAION) may occur. This may or may not be due to tadalafil. If this serious problem occurs, seek immediate medical attention.

Sexual activity may put extra strain on your heart, especially if you have heart problems. If you have heart problems or experience any of the following serious side effects during sex, stop and seek immediate medical attention: severe dizziness, fainting, chest pain.
For males, in the very unlikely event you have a painful or prolonged erection lasting 4 or more hours, stop using this drug and seek immediate medical attention, or permanent problems could occur.
