Not many drugs work perfectly and Viagra is no exception. An awful lot of drugs have side effects arising because they are flowing throughout the body and could affect parts of it unintentionally. For instance, aspirin does help relieve pain but it is also known to erode the stomach lining and even thin the blood. Those are some notable effects of aspirin.

As for Viagra, some of the most notable problems include little things like headaches and bigger things like heart attacks. The heart attack possibility is one main reason why Viagra is a prescription drug, unlike other such drugs as aspirin which are over-the-counter drugs. A GP needs to fully understand your medical history and make certain Viagra won’t lead to a heart attack. Some patients who take Viagra are reported to get painful, long-lasting erections and need to see a doctor to have the problem solved.

Last but not least, there’s a bit of concern that an increasing number of men, particularly younger ones who recreationally take Viagra and who don’t specifically need it, could end up becoming dependent on the drug. Simply put, they could become unable to maintain an erection with the absence of Viagra.
