Viagra, Cialis and Levitra. What is the difference?

Viagra (Sildenafil), also called “The Blue Pill”, is put on sale in 25mg, 50mg and 100mg pills. You can take Viagra once per day, from half an hour to 4 hours before sexual intercourse.

The common side effects of Viagra are sternutation, flushing, headaches, dyspepsia (heartburn, pain), giddiness, palpitations (when you feel your heartbeat), and excessive sensitivity to light (photophobia), among serious side effects are priapism (a painful condition when an erection doesn’t stop for 4 hours), cardiac seizure, hypotonia, apoplexy and in some cases even sudden death. Some cases of blindness caused by Viagra also took place, but it is still a controversial point.

The action of Viagra begins in about 45 minutes on average, and is still on for 4 hours. The price of the pills is approximately $10 per pill. There is a great number of cheap versions of Viagra you can buy online, nevertheless the point is that a lot of these versions are counterfeit and unlawful. You can find generic versions (with the same side effects) at a low price sold online.

Cialis (Tadalafil) is more effective than Viagra in many cases, as it is a stronger PDE5 inhibitor. For comparison a 100mg dose of Viagra is equivalent to a 20mg dose of Cialis.

Cialis Common side effects are indigestion, flushing, headache, back pain. You can feel the back pain from 12 to 24 hours of taking the medicine; but they end in several days. Cialis also can cause priapism and vision changes (when it is difficult to see the difference between blue and green colors)

The advantage of Cialis over Viagra is that Cialis is in action to 36 hours in comparison with 4 hour-effect of Viagra. The price of Cialis may be up to $22 per pill. As well as Viagra, Cialis also has cheap generic versions you can buy online.

Levitra (Vardenafil) is sold in 2.5mg, 5mg, 10mg and 20mg orange colored pills. 50mg of sildenafil can be compared to a 10mg dose of Levitra.

Levitra also has side effects, which include nausea, back pain, vision changes, abdominal pain, photosensitivity, organ swelling, eye pain, palpitation, high blood pressure, priapism and rashes. Among serious side effects are penile tissue, cardiac seizure, damage and permanent impotency. The price of Levitra is up to 20 hours per pill. Counterfeit versions cost cheaper.

As the big 3 erectile dysfunction drugs are associated with serious side effects, there are a lot of ‘herbal Viagra alternatives’ sold in the market. These drugs are preferable over the ED drugs as though they begin to work in 15-30 minutes, and their action is on for 4 hours, like Viagra, they don't possess any side effects. It is so, because they are produced of herbal ingredients. The popularity of these drugs among patients with impotence problems is growing because they have a very affordable price and cost about $1.5 per pill.
