At this point of the 21st century pretty much everybody, impotence patients and otherwise, knows what generic Viagra (active ingredient Sildenafil citrate) is and what it does. The mechanism of action is in fact quite simple. What generic Viagra does is inhibit a chemical known as PDE5, which constricts the muscles in the penis, effectively leaving it bereft of blood. By blocking said compound it relaxes these muscles and allows for more blood to reach the penis and to remain there for a longer time, enabling the erectile dysfunction patient to achieve a proper erection for satisfactory sexual intercourse. Generic Viagra has proven to be both safe and effective, and with mostly few and mild side effects.

However, that does not mean that a patient should just carelessly swallow a bunch of Sildenafil tablets and expect immediate and automatic results. First of all, Sildenafil citrate has to be taken a predetermined amount of time before sexual relations are to take place. Second, the patient needs to be sexually aroused in order for the drug to exert its effects. Also, there exist some contraindications to take into account that include interactions with other medications as well as with alcohol and certain meals. One of the most important of these contraindications has to do with the ingestion of grapefruit juice.

Scientific research has led to the suspicion that grapefruit juice could increase blood levels of Sildenafil citrate. This combination could potentially lead to a drop in blood pressure, fainting and more severe cardiovascular effects. On the other hand, grapefruit juice may sometimes delayed the absorption of Sildenafil citrate, leading to disappointing results for erectile dysfunction patients. Either way, it is a lose-lose situation. That is the reason why Sildenafil tablets should be administered with a glass of water instead of any other type of beverage. Another alternative is to use generic Viagra soft tabs or oral jellies, which do not require the use of liquids to ingest.

Of course, this is only one contraindication to bear in mind  when a person is looking to buy this drug, whether it is Viagra online or otherwise (on a side note, ordering Viagra online is the best option). It is important to be informed and consult a doctor to determine aspects such as dosage and strength and others that vary from patient to patient. As said before, this is a very safe drug when used appropriately, and avoiding substances like grapefruit juice will guarantee a pleasant and rewarding experience when buying Viagra online.
