Viagra or Sildenafil (scientific name and active ingredient of the pill) is a medicine used to treat erectile dysfunction in men, it lasts up to 8 hours, which means that it enters and leaves your system faster than Cialis, which is another very potent drug that helps with erectile dysfunction, like the Levitra, which lasts 8 hours like Viagra, while the Cialis can last up to 36 hours. Some people prefer Sildenafil because if they experience side effects, even if they are minor, they would prefer not to experience them for up to 36 hours. On the other hand, some people prefer Cialis mainly because it lasts a prolonged period of time.

Why Viagra is the better choice?

Another reason why some people prefer Sildenafil, compared to Levitra, is because it has fewer contradictory medications and very similar functions in terms of absorption.
Viagra works by helping to relax the blood vessels in the penis, which allows blood to flow into the penis causing an erection. If you plan to use Viagra, you should take it one hour before the planned sexual activity.

This potent drug, in addition to helping to treat erectile dysfunction is also used to treat pulmonary arterial hypertension.
In South Africa, Erectile dysfunction is suffered by more than 30% of older men. Erectile dysfunction affects more than 150 million men worldwide, including approximately 20 million Europeans, 30 million Americans and approximately 10 million men. Every 10 men after 21 suffers from erection infractions. Complete erectile dysfunction is observed in 5% of men at the age of 40 years and in 15% at the age of 70 years. 35% of men with erectile dysfunction have a high degree of infraction of an erection. Man should not be reconciled with the infraction or the absence of an erection. Approximately 3.5 million men say they have used Viagra and claim that it has worked for them, most without suffering from side effects, on the other hand, two million South African men also claim to have felt improvement in terms of pulmonary problems when using (with medical prescriptions and recommendations of their doctors) Viagra.

This medication does NOT cause erections on its own, sexual stimulation is still necessary. Viagra does NOT cure erectile dysfunction, increases a man’s sexual desire, protects against sexually transmitted diseases or serves as a male contraceptive method.

Please be careful with side effects

If you use Viagra, you should not take more than one tablet in 24 hours and should not be taken with other medications for erectile dysfunction. An erection is possible for up to four hours after taking it (although that does not mean that the erection will last four hours).
Despite having advantages that are very good, Viagra also has disadvantages, which would be its side effects which would then be:

• Headache
• Skin redness
• Abnormal or blurred vision
• Indigestion and migraines
• Covered nose or comosa
• Muscular and back pain
• Machines, nausea and vomiting

Very occasionally, Viagra can cause a painful erection or an erection that does not go away. If this happens and the erection lasts more than 4 hours, you should go to the nearest emergency service. Prolonged erections can be dangerous, for these bad effects and more, it is advisable that if you plan to use this drug talk or consult your doctor first.
