Viagra's curative properties were discovered by accident, when researchers were testing a medication considered to be used for heart disease treatment. Though the desired effect wasn't observed, men in the test group experienced strong erection during the studies. Further testing and studies showed that Sildenafil (Viagra's active substance) is an effective medicine for erectile dysfunction treatment.

The main principle of the Generic Viagra drug action is increasing blood flow into the penis; as a result a man is able to achieve and maintain erection when he is sexually aroused. Anyway, it should be pointed out that Sildenafil causes erection only if there is sexual excitement, and it does not work if arousal is absent.

Just like similar drugs of the group, namely, Cialis and Levitra, Generic Viagra should be taken some time in advance before having sex, which is 30-60 minutes at best, and like the above mentioned medicines it remains active in the human body only for a certain period of time, that is, for about four hours. All in all, there's only a slight difference in the effects of Viagra, Cialis and Levitra, while their mechanism of work is very similar.

There have been many discussions as to the safety of generic drugs for human health; but numerous investigations have proved that quality generic drugs are not worse than name-brand drugs. In spite of fact that the latter ones are under patent protection (which might mean that the patent holder is the single manufacturer of the product), in many countries of the world it is not the case, and a generic alternative is often good and available at one's service. While products of famous brands are more expensive than their duplicates, it doesn't mean at all that they are better than generic drugs. This is also true for Generic Viagra, which is considerably cheaper than brand name Viagra (both in online stores and local ones), but shows the same effects.

Generic Viagra is rather easy in application. The drug is taken by mouth when it is necessary between four hours and half an hour before the sexual intercourse (tip: the most effective time for usage is around one hour before sex). There also are so-called soft tabs (Generic Soft Viagra). They are very effective for erectile dysfunction treatment, too, though, as clear from the name, show a softer action than regular Generic Viagra. These soft drugs consist of the same chemicals, but they aren't swallowed and digested, but are absorbed into the blood by their placement under the tongue. This method of administering ensures a faster effect of Generic Soft Viagra than that of regular pills.

Generic Viagra is often bought and sold without a doctor's prescription, as usually men don't want to discuss their problems connected to impotence with anyone. This is generally okay, as the side effects of Generic Viagra are usually mild to none; however it is important that one reads the drug precautions carefully before taking Viagra. Make sure you are not currently taking nitrate medications (e.g. nitroglycerin and isosorbide dinitrate), nitroprusside (it is used for reducing blood pressure), erythromycin (e.g. in the treatment of respiratory tract infections), azole antifungals (used for treating serious fungus infections), rifamycins (prescribed during tuberculosis), medicines for high blood pressure treatment, certain HIV protease inhibitors, delavirdine (for HIV treatment), cimetidine (dermatological diseases), and some other drugs.

If you are already using Generic Viagra, please also note that it is advisable to limit alcohol intake with Viagra, because it can aggravate the drug's side effects. As the medicine may cause dizziness, one should be careful when performing tasks that need good concentration (e.g. driving). Dizziness and lightheadedness that may occur after rising from a seated or lying position may be avoided when getting up slowly.

Other side effects that were noted during Generic Viagra history application include headache, flushing, stomach upset, diarrhea, and dizziness. If these effects are present or worsen, it is better to notify one's doctor at once. There have been very rare cases of painful erection or urination problems, vision problems, skin rash, chest pain, fainting, and foot/ankle swelling. If one has a painful or long erection (more than four hours), it is recommended to stop using Generic Viagra.

Generally, the effective action of Viagra is such, that 90%+ of men are ready to bear with the above side effects, as this drug brings back the joy of normal sexual life to couples worldwide. Some men use Viagra from time to time even if they have no problems with getting natural erection. They claim that the sensations this drug produces get them to yet higher levels at pleasure.

Another very important advantage of buying Generic Viagra in Online Pharmacy store is that the person doesn’t need to tell about his erectile disorder to anyone, even to his partner if he wishes so. Ordering Viagra online is easy, safe and fast.
