You should tell your doctor before talking these drugs if you have heart disease, high or low blood pressure, seizures, liver or kidney disease, a blood cell or bleeding disorder, a stomach ulcer, hearing or vision problems, an eye disorder or physical deformity of the penis.

edit Effectiveness

Studies on Cialis suggest that it is effective 88% of the time. For patients with diabetes, it is effective 56% of the time. [1]

Initial studies on Levitra suggested that it was effective between 74% and 87% of the time. It is less effective for men with hypertension, dyslipidaemia or diabetes. [2]

edit Prescription

Cialis is the only erectile dysfunction drug that can be prescribed as a once-daily pill. It is also effective for longer – up to 36 hours. It is also used to treat pulmonary arterial hypertension.
