As men age, their desire for a healthy, fulfilling sex life remains as strong as ever, but their body will sometimes let them down. Nearly two thirds of males over the age of 50 report having trouble achieving an erection at least some of the time, and this percentage only gets higher with age. A recent survey of men found that 90% of men over the age of 75 suffered from erectile dysfunction. Fortunately there are many simple, reliable and safe medical treatments that men can use to achieve lasting erections and take back control of their sex lives.

Perhaps the best known of these medications is Viagra. It was the first drug ever marketed as a treatment for erectile dysfunction, and it has remained the most popular among men for over twenty years. This is in great part due to its reliability, and to the fact that it can be prescribed by any physician and acquired in any pharmacy. The active compound of Viagra is called sildenafil, and it works by increasing blood flow to the penis. This compound is no longer under an exclusive patent by Pfizer, the manufacturer of Viagra, which is why in recent years there has been an increase in generic brand sildenafil medicine. These brands have varying levels of trustworthiness, and some of them can be legally sold in South Africa. This is why, although it is more expensive than some off-brand alternatives, Viagra remains the preferred choice of most men who seek treatment for erectile dysfunction.

Viagra is very effective, helping 80% of men keep an erection hard enough for sex. In addition, it is very convenient, because it only needs to be taken when the man intends to have sex, so there’s no risk of forgetting to take the treatment, or taking the incorrect dosage. Viagra acts very quickly. It starts being effective 20 to 30 minutes after being ingested, and the man can initiate sex up to four hours after he has taken it. This means that he and his partner don’t need to rush, and can enjoy sex with natural spontaneity.

Because it affects blood pressure and blood flow, Viagra shouldn’t be taken without a doctor’s prescription for safety reasons. Men who have a history of cardiac illness or a high risk of cardiovascular disease are advised to avoid taking Viagra. It should also be avoided when the man is taking medicine for hypertension, nitrate-based medicine, alpha blockers, or any other medication for the treatment of erectile dysfunction.

Viagra can cause side effects both minor and serious. Some common side effects include headache, upset stomach, flushing, blurry vision, runny nose, dizziness, rash, muscle pain or back pain. These side effects are not an immediate cause of concern. However, the man should seek medical attention if he experiences sudden hearing loss, sudden vision loss in one or both eyes, or an erection that won’t go away after four hours. Viagra can be risky when taken by men who suffer from cardiac disease, so the importance of speaking to one’s physician before beginning treatment with Viagra can’t be overstated.
