For more specific information, consult with your doctor or pharmacist for guidance based on your health status and current medications, particularly before taking any action. Effects of Viagra on Blood Pressure When Nitroglycerin is Subsequently Administered: Based on the pharmacokinetic profile of a single 100 mg oral dose given to healthy normal volunteers, the plasma levels of sildenafil at 24 hours post dose are approximately 2 ng/mL (compared to peak plasma levels of approximately 440 ng/mL). In the following patients: age >65 years, hepatic impairment (e.g., cirrhosis), severe renal impairment (e.g., creatinine clearance <30 mL/min), and concomitant use of erythromycin or strong CYP3A4 inhibitors, plasma levels of sildenafil at 24 hours post dose have been found to be 3 to 8 times higher than those seen in healthy volunteers.

There have been a few isolated reported incidents of heart problems in patients taking Viagra. The incidents include abnormal heart rhythm (atrial fibrillation and ventricular arrhythmia), low blood pressure, myocardial infarction, and blood clots (thromboembolism).
