Many men experience erectile dysfunction at some point in their lives. It can affect a man's health and their relationships. There are many different treatments for erectile dysfunction, including lifestyle changes and oral medications. Some treatments may be more invasive, such as intracavernosal injections and external prosthetic devices.

Many men choose oral medications as their first line of treatment for erectile dysfunction. Many of these medications are effective and come with minimal side effects. These medications work by increasing the production of nitric oxide, which relaxes the muscles in the ***** and increases blood flow. This in turn enables men to achieve an erection in response to ***** stimulation.

Medications for erectile dysfunction can also be delivered directly to the patient's home. In the United States, Viagra can be delivered to their homes for less than a dollar per dose. PDE5 inhibitors block the phosphodiesterase enzyme and can increase the duration of an erection.

Some of the common side effects associated with oral medications for erectile dysfunction include headache, facial flushing, and upset stomach. Some medicines can also cause blue-colored vision. Cialis, however, does not have visual side effects, but it can cause back pain and joint aches.
