1. Viagra
As of now, this is utmost popular cure against impotent sufferers due to its effectiveness. But this can be prescribed only by a qualified doctor. The Viagra that the online sites are selling isn’t real. It’s essentially a fake version of Viagra. The normal cost of a Viagra pill is around $10, but if taken in hefty amount, the cost can also come down to $1.5 a pill. The ones sold over the internet may be cheap, but are not very effective either. The pill’s effect can be felt within an hour of its intake.

But this pill has adverse side effects too like dizziness, sneezing, dyspepsia, headaches, photophobia, flushing, priapism, palpitations, strokes, heart attacks, and even sudden death. Though the serious ones are very rare, but may happen. But the ordinary ones are really recurrent.

2. Cialis
This is another drug which is responsible for the same results as Viagra. But both indeed have un-identical structures chemically. Cialis is about 5 times more stronger compared to Viagra, i.e. 20mg of Cialis is about equal to 100mg dosage of Viagra. This pill can be as costly as $22 per pill if you prefer a brand name tablet. The actual chemical name for this is Tadalafil, but this is marketed as Cialis by the Eli Lilly & Company.

This pill gains better popularity due to its long lasting effects. Cialis is claimed to last for as long as 36 hours as compared to 4 hours of duration by Viagra, and is often called as “weekend pill” because of the large time span of its effectiveness. Also Cialis comes with a shorter list of side effects as compared to Levitra or Viagra. The common ones are flusing, back pain, headaches, muscles aches, and stuffy nose. But most recently, the reports from FDA have discovered that it can also lead to vision loss. Some stories also bind Viagra to vision losses.

3. Levitra
This again is identical to Cialis and Viagra when it comes to the role it plays as well as its efficiencies. The compound name of this is Vardenafil. Since this inhibit  PDE5, it does the same effects as previous two. Side effects include abdominal pain, nausea, eye pain, palpitation, back pain and permanent potency loss. It lasts normally for 4-5 hours, and starts its effects within an hour. The ratio of effectiveness between Levitra and Viagra is 1:5.

4. Herbal Products
Some of the impotence tablets are also manufactured out of herbal ingredients. The newer tablets have pretty much similar result to that of chemical drugs. The time in which it can show it’s effect is normally around 30 minutes, and the effect lasts as long as 4 hours. Most important benefit of these herbal alternatives is that they don’t have any side effects due to herbal ingredients, and are pretty cheap compared to its competitive chemical alternatives.
