Cialis (tadalafil) is a highly-efficient prescription medication used to treat male impotence. If any of your family members had any eye problems, especially retinitis pigmentosa, taking this drug may not be completely safe for you, as you can experience a very rare but serious side effect – vision loss. Such mild and short-lived side effects as headache, heartburn, facial flushing, diarrhea, upset stomach, cough, flushing and redness can be ignored if they do not change in intensity over time. In fact, in most cases they are most likely to go away on their own. More serious side effects that must be reported to your doctor as soon as possible to prevent them from getting worse include dizziness, chest pain, hives, rash, ringing in the ears, priapism, loss of vision, loss of hearing and blurred vision.
Generic names: Tadalafil
