If you have erectile dysfunction, you may be prescribed Viagra. However, what happens if that medication doesn’t work? The good news is that there are many options for treating erectile dysfunction. Let’s explore what Viagra is, why it may or may not work, and what to do if this treatment doesn’t improve your erections.
Although other issues such as nerve damage and hormone abnormalities can also lead to erectile dysfunction, the failure of the blood vessels to dilate properly is one of the more common causes, Wittert said. "This is an early abnormality in the pathway to more serious heart disease."

Before we get into why it might not work for you, let’s discuss how Viagra actually works. Viagra is the brand name for the drug sildenafil, which is a PDE5 inhibitor. PDE5 is an enzyme that can make it difficult for your blood vessels and arteries to relax and dilate. This can reduce the amount of blood flow to various parts of the body, including the penis. PDE5 inhibitors reduce the amount of the PDE5 enzyme in your body to increase blood flow for your erections. Therefore, sildenafil and other PDE5 inhibitors address blood flow problems that may cause erectile dysfunction.
Impotence treatments were discussed in the oldest Chinese text, The Yellow Emperor’s Classic of Internal Medicine, which describes traditional Chinese medicine during the time of the Yellow Emperor’s rule which ended around 2600 BC.

As with most medications, many doctors start you off at the lowest therapeutic dose and increase from there. For men between 18 and 64, the recommended dose for Viagra is 50 milligrams. For men 65 and older, the recommended dose is 25 milligrams. However, it may be that the dose is too low for you if it’s not improving your erectile dysfunction symptoms. Therefore, we may try increasing the dose until we find one that works well for you. Doses can go up to 100 milligrams, so we may try incrementally increasing the dose until we reach that point, depending on your unique situation.

Sound waves directed at the penis and surrounding tissues stimulate blood flow, cellular growth and generation of new, healthy blood vessels (neovascularization). Studies show that acoustic (sound) wave therapy such as pulse therapy also provides long-term improvement of physiological mechanisms involved in erections. No side effects have been reported by men using pulse therapy for ED.5
