Erectile dysfunction (ED) or as known to a lay man, impotence, is one of the most common sexual problems faced by men. Erectile dysfunction is a condition in which a man is unable to achieve or maintain erection when sexually aroused, leading to a unsatisfactory sex life. Men are often hesitant to share their problem with not only their partner but also a doctor.

But, instead of feeling embarrassed or conscious of the situation, it is advisable that you at least consult your doctor for further help as well as share it with your partner. This can actually help you in making the situation easy and smooth. Although ED cannot be completely cured, it can definitely be treated with the help of prescription medications such as Viagra, Cialis and Levitra.

All three of these medications help you maintain or achieve erections by increasing blood flow into your penis. Viagra is a blue pill which can be taken by men of all ages, but the man should be at least 18 or above. You need to take the pill at least 30 to 60 minutes before you engage in sexual activity. Its effects last for 4 hours of taking the pill. Cialis is also known as the 'weekend pill' as it is effective for 36 hours after taking the pill, which is why it is more common among the middle-aged men. Levitra, on the other hand, is more suitable for older men and is effective for 5 hours. You can now treat impotence with the help of these pills and have desirable erections when engaged in sexual intercourse.

These pills should be avoided if you are suffering from certain health conditions such as recent heart attack or stroke, low blood pressure, severe liver dysfunction, or if you are using medications that contain nitrate in any form. Some of the commonly noticed or reported side effects of these pills are change in colour vision, stomach upset, headaches, back pain, facial flushing, muscle aches and stuffy nose.
