When one mentions the term erectile dysfunction drug, there are 3 names which spring to mind: Viagra, Cialis and Levitra. All work in a similar function, but there are differences apart from simply coming from different manufacturers of erectile dysfunction drug.

The study of side effects of erectile dysfunction medicine is a branch in itself. Normally we associate side effects with drugs- Viagra, Cialis or Levitra, however there are other aspects of erectile dysfunction medicine- such as implants which can have significant side effects as well.

The complete list of possible side effects from any of the three major erectile dysfunction drugs - Viagra, Cialis or Levitra - could easily fill several pages. The majority of side effects pertain to drug interactions. For example, men taking nitroglycerine-type heart medications are warned to avoid such erectile dysfunction drugs. The good news if you can avoid such interactions, you will not suffer from any significant side effects in finding your unique cure for erectile dysfunction.

Allergic reactions to erectile dysfunction medicine can be a concern. One has to weigh up the effects of the reaction versus the quality the erectile dysfunction medicine brings to the sex life. An allergic reaction is usually a sign the immune system has gone into overdrive- it will be worth a visit to your doctor to be sure.

About 16% of men get headaches from taking Viagra. Indigestion is present in about seven percent. Nasal congestion is known to affect 4% of users. Furthermore urinary tract infections have been reported, by about 3% of those who take Viagra. Less common is diarrhoea. Similar numbers and symptoms are reported for both Cialis and Levitra.

The numbers above are all relevant to the person taking the erectile dysfunction medicine. Some sufferer's may not report the symptoms, some will exaggerate the symptoms. Furthermore many men will have underlying conditions which cause the side effect- so these an not be taken as seriously.

In extremely rare cases, a condition called NAION (Non-Arteritic Anterior Ischemic Optic Neuropathy) can occur. This involves a sudden loss of vision in one or both eyes. Anyone who suffers such an incident as a result from taking erectile dysfunction medicine should see their doctor immediately. Sometimes diabetes can contribute to such neurological side effects.

Side effects can occur in other treatments for erectile dysfunction:

Penile implants, while relatively safe these days to come with certain risks. Like any surgery, allergic reaction to the anaesthetic is possible. Furthermore the implant may result in scarring, which may require the removal of the implant. More than 85% of men with penile implants have no need to have them removed.

There are also mental aspects to consider in terms of side effects of erectile dysfunction medicine. For example, a counsellor may recommend the wrong action to the sufferer- changing jobs for example. This may result in negative psychological effects.

As with any form of treatment there are certainly side effects to erectile dysfunction medicine. As 80% - 90% of men experience satisfaction with their treatment, it is safe to say you will more than likely experience the same.
