1.Learn about possible side effects. For most, but not all men, these drugs are quite safe. The only significant side effects are headache (16 percent of users), flushing (10 percent), upset stomach (7 percent), nasal congestion (4 percent), and rarely, visual disturbances (mostly in men with chronic eye conditions such as macular degeneration)
2.Research your insurance coverage. Some health insurers cover erection medications, but many provide only partial coverage, or none at all. However, even without insurance coverage these drugs are quite affordable. The Viagra dose most men take, 50 mg, costs about $10—a modest price to pay for an amorous evening free from erection worries!
3.Know that, despite their success, erection drugs also have limitations. They are ineffective in about 25 percent of cases. As severity of ED increases, their effectiveness decreases. For example, the drugs work well in many men with the beginnings of diabetic ED, but less well in diabetics with considerable cardiovascular and neurological damage. In men with mild erection balkiness, these drugs may not work in some situations—if a man feels particularly stressed, distracted or alienated from the sexual experience.
