Nitrates: Concomitant use with nitrates and nitric oxide donors in any form is contraindicated [see Contraindications (4.1)].Male sexual dysfunction is one of the most common health problems affecting men and is more common with increasing age. Chronic ED affects about 5% of men in their 40s and 15–25% of men by the age of 65. Transient ED and inadequate erection affect as many as 50% of men between the ages of 40 and 70. ordering levitra online FDA approval of Levitra was based on four multi-center, double-blind, randomized, placebo controlled, fixed-dose, parallel design trials. The studies enrolled a total of 2431 men with an average age of 57 years. The doses investigated were 5 mg, 10 mg, and 20 mg. An efficacy assessment was based on the Erectile Function (EF) Domain score of the validated International Index of Erectile Function (IIEF) Questionnaire and two questions from the Sexual Encounter Profile (SEP) corresponding to vaginal penetration achievement (SEP2), and the ability to maintain an erection for intercourse (SEP3).

So all of the above pretty much rounds up the question as for why Cialis in Canada (and the rest of the world, for that matter) is so out-of-this-world popular.
Geriatric — Healthy male elderly subjects (65 years or over) had a lower oral clearance of tadalafil, resulting in 25% higher exposure (AUC) with no effect on Cmax relative to that observed in healthy subjects 19 to 45 years of age. No dose adjustment is warranted based on age alone. However, greater sensitivity to medications in some older individuals should be considered [see Use in Specific Populations (8.5)].Carcinogenesis cialis in canada online Get emergency medical help if you have any of these signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat.

how to get a prescription for viagra Effects of Viagra on Vision: At single oral doses of 100 mg and 200 mg, transient dose-related impairment of color discrimination was detected using the Farnsworth-Munsell 100-hue test, with peak effects near the time of peak plasma levels. This finding is consistent with the inhibition of PDE6, which is involved in phototransduction in the retina. Subjects in the study reported this finding as difficulties in discriminating blue/green. An evaluation of visual function at doses up to twice the maximum recommended dose revealed no effects of Viagra on visual acuity, intraocular pressure, or pupillometry.Renal Impairment: In volunteers with mild (CLcr=50–80 mL/min) and moderate (CLcr=30–49 mL/min) renal impairment, the pharmacokinetics of a single oral dose of Viagra (50 mg) were not altered. In volunteers with severe (CLcr <30 mL/min) renal impairment, sildenafil clearance was reduced, resulting in approximately doubling of AUC and Cmax compared to age-matched volunteers with no renal impairment [see Dosage and Administration (2.5), and Use in Specific Populations (8.6)].
