Prescription Medicines
There are just five oral drugs that are approved by the FDA to cure erectile dysfunction issues. These drugs are Viagra, Stendra, Cialis, Staxyn, and Levitra. All of these drugs work by raising the flow of blood into the penis so that the sufferer of erectile dysfunction can get an erection when he is stimulated sexually.
However, these drugs may not be safe to take for certain types of patients and require consultation with a doctor. There may be concerns if the sufferer of erectile dysfunction is allergic to any drugs; if they are scheduled for a surgical procedure; if they are taking other prescription or non-prescription medications; or if they are taking long-acting nitrates to treat chest pains.
There may also be side effects from the use of these drugs, which can include headaches, flushing, temporary changes in vision, muscle pain, indigestion, and an erection that won't go away on its own - a rare condition that is called priapism.
