This information is intended for use by health professionals.

Each tablet contains 25 mg, 50 mg or 100 mg of sildenafil (as citrate) Excipient with known effect : Lactose monohydrate.

25 mg: White to off-white, rounded diamond-shaped tablets, of dimensions 9.2 x 6.7 mm, marked ?25? on one side. 50 mg: White to off-white, rounded diamond-shaped tablets, of dimensions 11.2 x 8.1 mm, marked ?50? on one side. 100 mg: White to off-white, rounded diamond-shaped tablets, of dimensions 14.1 x 10.2 mm, marked ?100? on one side. Treatment of men with erectile dysfunction, which is viagra medicine online purchase the inability to achieve or maintain a penile erection sufficient for satisfactory sexual performance. In order for Sildenafil to be effective, sexual stimulation is required. The recommended dose is 50 viagra discount cvs mg taken as needed approximately one hour before sexual activity. Based on efficacy and tolerability, the dose may be increased to 100 mg or decreased to 25 mg. The maximum recommended dosing frequency is once per day. If Sildenafil is taken with food, the onset of activity may be delayed compared to the fasted state (see section 5.2).

Dosage adjustments are not required in elderly patients (? 65 years old). The dosing recommendations described in 'Use in adults' apply to patients with mild to moderate renal impairment (creatinine viagra medicine online purchase clearance = 30 - 80 mL/min).

Since sildenafil clearance is reduced in patients with severe renal impairment (creatinine clearance 150 ?M).

Given sildenafil peak plasma concentrations of approximately 1 ?M after recommended doses, it is unlikely that Sildenafil will alter the clearance of substrates of these isoenzymes. There are no data on the interaction of sildenafil and non-specific phosphodiesterase inhibitors such as theophylline or dipyridamole.

In vivo studies: Consistent with its known effects on the nitric oxide/cGMP pathway (see section 5.1), sildenafil was shown to potentiate the hypotensive effects of nitrates, and its co-administration with nitric oxide donors or nitrates in any form is therefore contraindicated (see section 4.3). Riociguat: Preclinical studies showed additive systemic blood pressure lowering effect when PDE5 inhibitors were combined with riociguat. In clinical studies, riociguat has been shown to augment the hypotensive effects of PDE5 inhibitors.

There was no evidence of favourable clinical effect of the combination in the population studied.

Concomitant use of riociguat with PDE5 inhibitors, including sildenafil, is contraindicated (see section 4.3). Concomitant administration of sildenafil to patients taking alpha-blocker therapy may lead viagra medicine online purchase to symptomatic hypotension in a few susceptible individuals.

This is most likely to occur within 4 hours post sildenafil dosing (see sections 4.2 and 4.4). In three specific drug-drug interaction studies, the alpha-blocker doxazosin (4 mg and 8 mg) and sildenafil (25 mg, 50 mg, or 100 mg) were administered simultaneously to patients with benign prostatic hyperplasia (BPH) stabilized on doxazosin therapy. In these study populations, mean additional reductions of supine blood pressure of 7/7 mmHg, 9/5 mmHg, and 8/4 mmHg, and mean additional reductions of standing blood pressure of 6/6 mmHg, 11/4 mmHg, and 4/5 mmHg, respectively, were observed.
