Before we get into discussing Cialis and other erectile dysfunction medications. Lets discuss what erectile dysfunction (ED) is. When a man can't get an erection to have sex or can't keep an erection long enough to finish having sex, it's called erectile dysfunction. Complete erectile dysfunction is known as impotence. Erectile dysfunction can occur at any age, but is more common in men age 65 and order.

There are many way to treat erectile dysfunction. These treatments include Oral medications (ie. Viagra (Sildenafil), Cialis (Tadalafil), and Levitra (Vardenafil). As well as injection therapy, muse intra-urethral therapy, hormone replacement therapy, surgical implants, vacuum pump, vascular surgery, and psychological counseling.

One of the most popular treatments available is oral medication. The big three available for treating erectile dysfunction are Viagra (Sildenafil), Cialis (Tadalafil) and Levitra (Vardenafil). The first to be approved by the FDA was Viagra, in 1998. Levitra and Cialis soon followed and were approved in 2003. Since their inception, millions of prescriptions have been written for these (ED) medications.

Viagra, Levitra, and Cialis are chemically known as phosphodiesterase Type 5 (PDE5) inhibitors. These three medications perform in a similar fashion. They do not cause an immediate erection, but they due allow an erection to occur when there is sexual stimulation. This erection occurs when the chemical inhibitors block the chemical in the penis that normally causes an erection to subside. This increases the amount of blood to the penis, which causes the penis to become erect and stay erect.

Viagra has shown to be an effective treatment for ED, with approximately 70% of Viagra patients reporting a positive response. Although Levitra and Cialis have only been on the market since 2003, they are also showing success rates like those of Viagra. While these medications have many of the same characteristics, they also have differences.

The variables are dosage, duration of effectiveness and possible side effects. For example, Viagra and Levitra both start working after about 30 minutes. With Viagra, the effects last for about 4 hours. On the other hand, the effects of Levitra last for around 5 hours. Cialis is supposed to be the fastest acting of the three, with effects taking place within 15 minutes and lasting for up to 36 hours. Individuals who test all three medications often come to different conclusions about which drug works better for them. At the present there has been no study comparing these three medications. And since Viagra, Cialis, and Levitra work in the same way, it's very probable that if you have failed with one, you will most likely fail with the other.

Although Viagra, Levitra and Cialis have been beneficial for many men, some men should not use these drugs, due to interactions with other drug prescriptions and other health conditions. Men who have suffered a heart attack, stroke, or life-threatening heart rhythm in the last six months should not use these medications. As these drugs can cause dangerous reactions with other drugs, they should not be taken with nitrate medications, alpha-blocking medications, or with the drug Amyl nitrate.

There are also possible side effects when using Viagra, Levitra, or Cialis, including rash, headaches, facial flushing, nasal congestion, painful erection, chest pain, indigestion and visual disturbances. Before taking any medication, always consult your physician about possible side effects and any possible health and drug interactions.
