Viagra (sildenafil) is a prescription medication used to treat erectile dysfunction. The most common side effects of Viagra include headache, facial flushing, and upset stomach. There are no controlled clinical data on the safety and efficacy of Viagra patients who suffered a myocardial infarction (heart attack), stroke, or life-threatening arrhythmia within the last 6 months. If prescribed, this should be done with caution. Heart attacks, stroke, irregular heartbeats, and death have been reported rarely in men taking Viagra. Most, but not all of these men, had heart problems before taking this medication. It is not possible to determine whether these events were directly related to Viagra. For more specific information, consult with your doctor or pharmacist for guidance based on your specific condition and current medications. snorting viagra itraconazole (Sporanox)
In a clinical pharmacology study of patients with erectile dysfunction, single doses of vardenafil 20 mg caused a mean maximum decrease in supine blood pressure of 7 mmHg systolic and 8 mmHg diastolic (compared to placebo), accompanied by a mean maximum increase of heart rate of 4 beats per minute. The maximum decrease in blood pressure occurred between 1 and 4 hours after dosing. Following multiple dosing for 31 days, similar blood pressure responses were observed on Day 31 as on Day 1. Vardenafil may add to the blood pressure lowering effects of antihypertensive agents [see Drug Interactions (7)].HYPROMELLOSES

When mild vasodilators are taken in combination, blood-pressure-lowering effects of each individual compound may be increased. Substantial consumption of alcohol (e.g., 5 units or greater) in combination with Cialis can increase the potential for orthostatic signs and symptoms, including increase in heart rate, decrease in standing blood pressure, dizziness, and headache. Tadalafil did not affect alcohol plasma concentrations and alcohol did not affect tadalafil plasma concentrations. [see Warnings and Precautions (5.9) and Clinical Pharmacology (12.2)].
