Viagra Dosage and Administration

Take the drug about one hour before you plan to have sex. Beginning in about 30 minutes and lasts for up to 4 hours, generic Viagra can help you get an erection if you are sexually excited. If you take sildenafil after a high-fat meal (such as pav bhaji, cheeseburger and French fries), the medicine may take a little longer to start working. If you prefer quicker effects, then simply disolve a tablet or half a tablet of Soft Tabs under your tongue 15 minutes before sex.

Viagra Side Effects

Like all medicines, Viagra can cause some side effects. These effects are usually mild to moderate and usually don't last longer than a few hours. Some of these side effects are more likely to occur with higher doses.
The most common side effects of sildenafil citrate are headache, flushing of the face and upset stomach. Less common side effects that may occur are temporary changes in colour vision (such as trouble telling the difference between blue and green objects or having a blue colour tinge to them), eyes being more sensitive to light or blurred vision.
Heart attack, stroke, irregular heartbeats and death have been reported rarely in men taking sildenafil citrate. Most, but not all, of these men had heart problems before taking the drug. It is not possible to determine whether these events were directly related to sildenafil.

Comparison of Cialis, Levitra and Viagra

• Cialis - Works faster about 15 minutes; Effects longer up to 36 hrs; Ideal choice for men who are very sexual active.
• Levitra - Works faster than Viagra; Takes 60 minutes before sexual activity; More potent module; Works faster on a full stomach; Works better at hard-to-treat cases in men whose impotence is caused by diabetes.
• Viagra - Widely used by 20 million men worldwide; It takes 30 to 120 minutes; Effects last up to 4 hrs approx.; Effects last up to 4 hrs approx.; 98% of total prescriptions for impotence.

These drugs might work for some but each male individual's body is unique and there are times when one drug is more effective than another. There are precautions and other considerations such as side effects on choosing the right drug for you. In brief, efficacy is approximately 70% with all 3 drugs. The side effect profile is similar among the 3 drugs, except that blue discoloration of vision (overlap with PDE-6 in the retina) is seen only with Viagra (<0.5%) and muscle aches only with Cialis (~5%). Otherwise, vasodilatory side effects (headaches, nasal congestion, flushing) are common with all, but are mild, and only rarely cause men to drop out of clinical trials (2-3% quit rate). All 3 will carry a contra-indication in men using organic nitrates. Otherwise, the long half-life of Cialis (17.5 hours) is noteworthy, earning this drug the nickname ‘weekender,’ as a single dose taken on Friday would still be exerting an effect Sunday (or even Monday).

Aside from the long half-life of Cialis, and the excellent track record of Viagra, the differences between the 3 drugs are not great. All appear to be effective and safe, provided concomitant nitrates are avoided. A potential for serious hypotension exists should an organic nitrate be used along with any of these three PDE-5 inhibitors.
