VIAGRA is not for women or children.Non-arteritic anterior ischemic optic neuropathy (NAION), a cause of decreased vision including permanent loss of vision, has been reported rarely postmarketing in temporal association with the use of phosphodiesterase type 5 (PDE5) inhibitors, including Cialis. Most, but not all, of these patients had underlying anatomic or vascular risk factors for development of NAION, including but not necessarily limited to: low cup to disc ratio (“crowded disc”), age over 50, diabetes, hypertension, coronary artery disease, hyperlipidemia, and smoking. It is not possible to determine whether these events are related directly to the use of PDE5 inhibitors, to the patient's underlying vascular risk factors or anatomical defects, to a combination of these factors, or to other factors [see Warnings and Precautions (5.4)].The maximum recommended dose for Viagra (sildenafil), used to treat ED (erectile dysfunction), is 100mg per day. It does have interactions with other medications, so you may want to find out if you are taking any medications that may be interfering with it. Medications for hypertension (high blood pressure) are usually fine to take with it, as far as drug interactions go. Have any of your heart medications been increased, especially ones that are known to cause erectile dysfunction, such as the beta blocker family, Tenormin (atenolol), Lopressor (metoprolol) and others? Do you have any other physical conditions that may be causing it, such as other vascular problems, issues with nerves that send the arousal signal from the brain and spinal cord to the penis (common in diabetes), problems with the structure of the penis or the surrounding tissue, low testosterone, or use of tobacco, alcohol, or illegal drugs? If the medication is losing it's effectiveness for you, you may want to consult your doctor for an alternative. Other medications that are in the same family and work in a similar manner are Cialis (tadalafil) and Levitra (vardenafil), but if one does not work as well for you anymore, another may work better. All three of these medications inhibit an enzyme (PDE-5) that breaks down the substance produced by the penile tissue in response to sexual stimulation, and helps the erection occur. Cialis (tadalafil) is known as the "weekend pill," because it lasts approximately 17 to 36 hours. Levitra (vardenafil) is similar to Viagra (sildenafil), as it lasts about 5 hours (Viagra (sildenafil) lasts about 4 hours), but it is the one that works the fastest.

Caution is advised when PDE5 inhibitors are coadministered with alpha-blockers. PDE5 inhibitors, including Cialis, and alpha-adrenergic blocking agents are both vasodilators with blood-pressure-lowering effects. When vasodilators are used in combination, an additive effect on blood pressure may be anticipated. In some patients, concomitant use of these two drug classes can lower blood pressure significantly [see Drug Interactions (7.1) and Clinical Pharmacology (12.2)], which may lead to symptomatic hypotension (e.g., fainting). Consideration should be given to the following: order cialis Whippany, NJ 07981Product InformationIn a 12-week study performed in 186 patients (142 tadalafil, 44 placebo) with erectile dysfunction secondary to spinal cord injury, tadalafil significantly improved the erectile function leading to a mean per-subject proportion of successful attempts in patients treated with tadalafil 10 or 20 mg (flexible-dose, on demand) of 48% as compared to 17% with placebo.Sildenafil citrate is designated chemically as 1-[[3-(6,7-dihydro-1-methyl-7-oxo-3-propyl-1H-pyrazolo[4,3d]pyrimidin-5-yl)-4-ethoxyphenyl]sulfonyl]-4-methylpiperazine citrate and has the following structural formula:

men with erectile dysfunction (ED)Counterfeit Drugs: One Million Reasons Why it's Essential to Get Yours Legitimately viagra wiki The root cause of the narrowing of the arteries is caused by atheroma. Atheroma is like fatty patches or plaques that develop within the inside lining of arteries. (This is similar to water pipes that get furred up with scale.) Plaques of atheroma may gradually form over a number of years in one or more places in the body, commonly in arteries going to the heart, brain, legs and penis. In time, these can become bigger and cause enough narrowing of one or more of the arteries to cause symptoms and problems.

In a study of the effect of Levitra on QT interval in 59 healthy males [see Clinical Pharmacology (12.2)], therapeutic (10 mg) and supratherapeutic (80 mg) doses of vardenafil and the active control moxifloxacin (400 mg) produced similar increases in QTc interval. 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. canadian viagra It's foolish to start taking a medicine or stop taking a medicine on your own based on information you read here or any other internet web site because this could cause you to become seriously ill or die or worse even.

2.In the third study, a single oral dose of Viagra 100 mg or matching placebo was administered in a 3-period crossover design to 20 generally healthy males with BPH. In dose period 1, subjects were administered open-label doxazosin and a single dose of Viagra 50 mg simultaneously, after at least 14 consecutive days of doxazosin. If a subject did not successfully complete this first dosing period, he was discontinued from the study. Subjects who had successfully completed the previous doxazosin interaction study (using Viagra 50 mg), including no significant hemodynamic adverse events, were allowed to skip dose period 1. Treatment with doxazosin continued for at least 7 days after dose period 1. Thereafter, Viagra 100 mg or matching placebo was administered simultaneously with doxazosin 4 mg (14 subjects) or doxazosin 8 mg (6 subjects) in standard crossover fashion. The mean subject age in this study was 66.4 years.
