Viagra Safety

There were 26,000 reports of adverse events in patients taking Viagra and other prescription erectile dysfunction drugs, such as heart attacks and cardiac failure, according to the study.

In April 2012, The FDA approved Avanafil for ED treatement.  Avanafil has less side effects than Viagra and take effects faster.  Its is thought that because it acts faster it leaves the body more quickly so there is not as much time for the drug to cause side effects.

The new study, which was not sponsored by any ED drug maker, sought to determine the number of harmful side effects from erectile dysfunction drugs in roughly the ten years following their widespread availability.

The challenge in interpreting the results, Lowe said, is the limits on the information in the FDA’s database.Underlying conditions an individual patient may have, and the time between when a pill was taken and when a heart attack or other event happened, are not included in the records.

“There is a lot of limitations in the FDA’s database to link the drug as the causative agent in these cases,” Lowe said.

Further, he noted, it wasn’t possible to determine if problems arose from taking genuine medications or taking counterfeit drugs some men order online.

But patients should be aware of potential hazards from erectile dysfunction when considering taking counterfeit drugs.

“I do think it’s important for patients to consult their physicians, however, and not obtain these medications through the Internet,or some other source,”Lowe said.

“Some patients will go that route, after they’ve tried the normal medication and want to save cost,” he said, but”the safest way to go is to have the medication prescribed by your physician and obtained through the traditional pharmacy.”

In rare instances, men taking PDE5 inhibitors (oral erectile dysfunction medicines, including VIAGRA) reported a sudden decrease or loss of vision. It is not possible to determine whether these events are related directly to these medicines or to other factors. If you experience sudden decrease or loss of vision, stop taking PDE5 inhibitors, including VIAGRA, and call a doctor right away.

In the rare event of an erection lasting more than 4 hours—also known as priapism—seek immediate medical help to avoid long-term injury. Learn more about priapism and VIAGRA.

Sudden decrease or loss of hearing has been rarely reported in people taking PDE5 inhibitors, including VIAGRA. It is not possible to determine whether these events are related directly to the PDE5 inhibitors or to other factors. If you experience sudden decrease or loss of hearing, stop taking VIAGRA and contact a doctor right away.

The problem with PDE5 inhibitors is their tendency to interact with other drugs that cause a similar action in the body. Nitrates (nitroglycerin is the most common) cause blood vessels to dilate — increase in size and carry more blood with less resistance. Nitrates help heart muscle work less hard while allowing more blood to the muscle tissue, which means patients experiencing heart-related chest pain (angina) may take nitroglycerin to make their pain go away.

PDE5 inhibitors work in a similar way. Unfortunately, when you mix PDE5 inhibitors and nitroglycerin, the effects can double or triple and cause a sudden dangerous drop in blood pressure. The combination of these two types of drugs is so dangerous, the American Heart Association suggests patients should not take nitroglycerin within 24 hours of taking PDE5 inhibitors.
