Brand Name Medications - We only sell brand name Viagra manufactured in the United States by Pfizer, Inc.In the first study, a single oral dose of Viagra 100 mg or matching placebo was administered in a 2-period crossover design to 4 generally healthy males with benign prostatic hyperplasia (BPH). Following at least 14 consecutive daily doses of doxazosin, Viagra 100 mg or matching placebo was administered simultaneously with doxazosin. Following a review of the data from these first 4 subjects (details provided below), the Viagra dose was reduced to 25 mg. Thereafter, 17 subjects were treated with Viagra 25 mg or matching placebo in combination with doxazosin 4 mg (15 subjects) or doxazosin 8 mg (2 subjects). The mean subject age was 66.5 years.Levitra has systemic vasodilatory properties that resulted in transient decreases in supine blood pressure in healthy volunteers (mean maximum decrease of 7 mmHg systolic and 8 mmHg diastolic) [see Clinical Pharmacology (12.2)]. While this normally would be expected to be of little consequence in most patients, prior to prescribing Levitra, physicians should carefully consider whether their patients with underlying cardiovascular disease could be affected adversely by such vasodilatory effects.

A postmarketing study evaluating the effect of combining Levitra with another drug of comparable QT effect showed an additive QT effect when compared with either drug alone [see Clinical Pharmacology (12.2)]. These observations should be considered in clinical decisions when prescribing Levitra to patients with known history of QT prolongation or patients who are taking medications known to prolong the QT interval. cialis free offer Levitra nervousnessAnti-hypertensives (including calcium channel blockers)Si durante la actividad del sexo, usted nota mareo, náusea, o tiene dolor, entumecimiento, o cosquilleo en su pecho, brazos, cuello, o mandíbula, pare de hacer la actividad y llame de inmediato a su médico.
