Competition between pharmaceutical companies is fierce, especially when it comes to erectile dysfunction drugs. With such a high proportion of men suffering from impotence, combined with their interest in a simple oral solution, several large drug companies have begun fighting it out to become the number one treatment. As a result, three main drugs have emerged in recent years, proving themselves in terms of their popularity and success; Cialis, Viagra and Levitra. In order to determine which treatment is most suited to you, previous health conditions and the possible side effects need to be taken into account.
When discussing Viagra, we must first consider how it works. Viagra is used to treat impotence by helping men to attain and to keep an erection while sexually excited. It achieves this by encouraging greater blood flow into the penis. This increase in blood flow will allow for stronger, harder erections. There are possible side effects such as headaches, flushing of the face, and an upset stomach. Rare side effects include temporary blurring or loss of vision.
Cialis is different from Viagra, in that it can last up to thirty-six hours, allowing you and your partner more time for intimacy. It is also very similar to Viagra as it increases the blood flow to the penis allowing you to achieve an erection.
As with a large proportion of prescription medications, there are a number of possible side effects with Cialis, including an upset stomach, back pain, headaches and muscle aches. Rarer side effects include an erection that can last for more than four to six hours. If this happens, you must consult your doctor immediately, as it can lead to permanent tissue damage.
Levitra works via the same mechanism as Cialis and Viagra - to increase blood flow to the penis, provided you are sexually aroused. In addition, it will also work to decrease the blood flow after sex, thus reducing the erection before it gradually resides. The possible side effects of Levitra include an upset stomach, blurred vision and an erection that will last for up to six hours. In terms of functionality Levitra works in the same way as Viagra, taking approximately 45 minutes to take effect, and lasting for between 4-6 hours.
Viagra, Cialis, and Levitra have very similar side effects and all three treatments belong to a class of medications called PDE-5 inhibitors. It is important that you do not take these drugs in conjunction with any medication containing nitrates, as they can cause a dangerous drop in blood pressure. If you are unsure, then you must consult with your doctor.
Cialis is a prescription only treatment, thus you are required to obtain a valid prescription from your doctor, or via an online consultation. Thankfully, there are now websites set up to allow men to order online, while a registered doctor reviews your medical history. This serves to ensure you are safe and suitable for Cialis treatment. All this can be done from the comfort of your own home. You can order Cialis after completing your free online consultation
