Erectile dysfunction is a very common medical condition that can affect men of any background or age. They may have trouble achieving or sustaining an erection, which can lead to feelings of shame, embarrassment and anxiety. Fortunately, millions of men have achieved positive results and longer, harder erections after taking a small blue pill called Viagra. The drug is available in 25mg, 50mg and 100mg doses and should be taken orally approximately 30 minutes to one hour before engaging in sexual intercourse. Viagra only works in conjunction with sexual stimulation, and it should not be taken right after eating a meal high in fact or it will take longer to work. You should also talk to your doctor before taking Viagra if you have severe kidney or liver disease, are currently taking other types of medications or are older than 65. All of these factors can affect how Viagra works. Viagra can also lower your blood pressure, so be sure never to exceed the maximum dosage recommended by your doctor. If you follow the instructions, Viagra can help you enjoy better lovemaking!
