Yes, these drugs not only inhibit erection, they also prevent orgasm and ejaculation and for the purposes of erection.

So taking E.D. medication like Viagra could counteract the anti-erection effect of Zoloft, but one should always consult a doctor before mixing medications.

The simple answer is yes, however this is not based on solid medical findings but surveys on men done across the country over the last 10 years.

In essence, some medication use to treat E.D. can stimulate residual penile tissue that still exists in a man with an implant and that tissue can as a result expand, thereby increasing the man’s erection.

Clinical research is still being done to discover whether Viagra taken in conjunction with pellets (MUSE) or injections can additionally enhance a man’s ability to have an erection.

There have been clinic tests that have shown men taking other medications for other conditions such as diabetes, have had success in treating their E.D. with drugs like Viagra.

However, men who take nitrates or heart related medications are not prescribed E.D. related medications because their mixture can be lethal. Men taking certain medications must inform and consult their physicians before taking E.D. medications.

Sildenafil, also known as Viagra developed by Pfizer was the first oral drug approved by the FDA in the United States in 1998 for the treatment of Erectile Dysfunction.

Sildenafil inhibits PDE5, which is an enzyme that destroys a chemical in the body known as cGMP. By inhibiting the destruction of cGMP, Viagra allows cGMP to accumulate.

The cGMP in turn prolongs relaxation of the smooth muscle of the corpora cavernosa.

In turn, relaxation of the corpora cavernosa smooth muscle allows blood to flow into the penis resulting in increased engorgement of the penis and an erection to occur in a man.

According to Pfizer, the manufacturer of Viagra, they indicate the drug is clinically proven to improve erectile function in most men with E.D.

A 28-week study was done by Pfizer of more than 500 men with E.D. where roughly 102 men took 100 mg of Viagra and 205 men took sugar pills and the remaining patients took other doses of VIAGRA. Results of the study found that 85% of men with E.D. who took 100 mg of Viagra achieved fairly strong erections versus 50% of men who were given sugar pills.

Pfizer also indicates that women too have been satisfied with the drug, showing in their study that 92% of women said “Viagra improved their partners’ erections” versus 19% of women whose partners were given sugar pills.

In prescribing Viagra, a doctor considers the age, general health status, and other medications the patient is taking.

The usual starting dose for most men is 50mg; however, the doctor may increase or decrease the dose depending on side effects and effectiveness. The maximum recommended dose is 100mg every 24 hours.

Many men will need 100mg of Viagra for optimal effectiveness, and some doctors are recommending 100mg as the starting dose. Nevertheless before taking the drug, patients must consult with their doctors and follow directions indicated on the containers of the medication.

According to the manufacturer of Viagra, Pfizer, some of the most common side effects of Viagra are headache, facial flushing, and upset stomach.

Moreover, Pfizer indicates that the drug may also briefly cause bluish or blurred vision or sensitivity to light. Furthermore, the drug maker warns that men experiencing chest pain, nausea, any other discomfort during sex, or an erection that lasts longer than 4 hours after taking Viagra, should seek immediate medical help.

In addition Pfizer states that there have been reports of sudden decrease or loss of vision in one or both eyes of some men after taking the drug. A rare side effect of Viagra, like the other E.D. drugs is “Priapism”, or a prolonged often painful erection of the penis.

If a man experiences priapism or an erection lasting more than four hours, he should seek immediate medical attention since the condition can cause damage to the penis and potentially lead to the inability to achieve an erection in the future.

Pfizer indicates that the side effects of the drug are more likely to occur with higher doses of Viagra and are usually mild, and will not likely last longer than a few hours. Warnings on the drug recommend men who take the drug to contact their physicians if the side effects of the drug continue to bother them.

Viagra is available as oral tablets at doses of 25, 50, and 100 mg. It should be taken approximately one hour before sexual activity. In some men, the onset of action of the drug may be as early as 10 to 20 minutes after being administered, and the drug effects are expected to work for up to 5 hours.

Viagra should be taken on an empty stomach for best results since absorption and effectiveness of Viagra can be diminished if it is taken shortly after a meal, particularly a meal that is high in fat.

A small number of patients have lost eyesight in one eye after taking Sildenafil (Viagra).

This type of vision loss is called non-arteritic anterior ischemic optic neuropathy (NAION). NAION causes a sudden loss of eyesight because blood flow is blocked to the optic nerve. It is not clear at this time if Viagra causes NAION.

It should be noted that NAION also occurs in some men who do not take Viagra. People who have a higher chance for NAION include those who: have heart disease, are over 50 years old, have diabetes, have high blood pressure, have high cholesterol, smoke; or have certain eye problems.

Doctors recommend that any patient should stop using Viagra if they have any loss in eyesight and immediately seek medical help.

Vardenafil, also known as Levitra was the second oral medicine approved by the U.S. FDA in 2003 in the US for the treatment of Erectile Dysfunction. Like Viagra, this drug also inhibits PDE5 which destroys cGMP that ultimately allows blood to flow into the penis resulting in increased engorgement of the penis and an erection to occur in a man.
