Patients should be made aware that both alcohol and Cialis, a PDE5 inhibitor, act as mild vasodilators. When mild vasodilators are taken in combination, blood-pressure-lowering effects of each individual compound may be increased. Therefore, physicians should inform patients that 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 [see Warnings and Precautions (5.9), Drug Interactions (7.1), and Clinical Pharmacology (12.2)]. cialis or levitra Postmarketing reports: Serious cardiovascular, cerebrovascular, and vascular events, including myocardial infarction; sudden cardiac death; ventricular arrhythmia; cerebrovascular hemorrhage; transient ischemic attack; hypertension; subarachnoid, intracerebral, and pulmonary hemorrhage have been reported in temporal association with the use of this drug.[Ref]Carcinogenesis, Mutagenesis, Impairment of Fertility112 Wharf Road

Physicians should advise patients to stop use of all phosphodiesterase type 5 (PDE5) inhibitors, including Levitra, and?seek medical attention in the event of sudden loss of vision in one or both eyes. Such an event may be a sign of non-arteritic anterior ischemic optic neuropathy (NAION), a rare condition and a cause of decreased vision, including permanent loss of vision, that has been reported rarely postmarketing in temporal association with the use of all PDE5 inhibitors. Based on published literature, the annual incidence of NAION is 2.5–11.8 cases per 100,000 in males aged ≥50. An observational study evaluated whether recent use of PDE5 inhibitors, as a class, was associated with acute onset of NAION. The results suggest an approximate 2 fold increase in the risk of NAION within 5 half-lives of PDE5 inhibitor use. From this information, it is not possible to determine whether these events are related directly to the use of PDE5 inhibitors or to other factors [see Adverse Reactions (6.2)]. canadian pharmacies viagra Therefore, Cialis administration with nitrates is contraindicated. In a patient who has taken Cialis, where nitrate administration is deemed medically necessary in a life-threatening situation, at least 48 hours should elapse after the last dose of Cialis before nitrate administration is considered. In such circumstances, nitrates should still only be administered under close medical supervision with appropriate hemodynamic monitoring [see Contraindications (4.1)].

Physicians should consider whether their patients with underlying NAION risk factors could be adversely affected by use of PDE5 inhibitors. Individuals who have already experienced NAION are at increased risk of NAION recurrence. Therefore, PDE5 inhibitors, including Cialis, should be used with caution in these patients and only when the anticipated benefits outweigh the risks. Individuals with "crowded" optic disc are also considered at greater risk for NAION compared to the general population; however, evidence is insufficient to support screening of prospective users of PDE5 inhibitors, including Cialis, for this uncommon condition.Kuthe A.Phosphodiesterase 5 inhibitors in male sexual dysfunction.
