In 1998, the FDA (Federal Food and Drug Administration) of the United States approved Viagra manufactured by the company Pfizer for use in treating male patients experiencing impotence, or more correctly Erectile Dysfunction. Viagra was the first medication of its kind specifically approved for ED treatment through oral consumption. The active ingredient, sildenafil citrate, was originally created to help patients with cardiovascular problems, but its positive effects on producing erections were discovered. It was found that sildenafil citrate increases blood flow to the pelvic area by causing muscles surrounding veins feeding the penis to relax. Viagra is easily recognizable by its unique shape (diamond) and color (blue).

Original tablets are imprinted with VGR25 for 25 milligram doses, VGR50 for 50 milligram doses and VGR100 for 100 milligram doses. Viagra is only available in the United States though a doctor’s prescription. However, it is available without a prescription from some countries that do not have such strict regulations. Generic pills are those that contain the same ingredients as brand names like Viagra only they are made by lesser known companies after the original patent has expired. Although Pfizer holds the patent on Viagra until the year 2020, various companies located outside the United States manufacture generic tablets that contain the active ingredient sildenafil citrate and can be used to treat Erectile Dysfunction the same as brand Viagra pills.

NOTE: You should take care when ordering any type of medications from online stores. A large number of false places claiming to be legitimate pharmacies and to sell authentic sildenafil citrate medications have risen in recent years. Such places often claim to provide very inexpensive Viagra without the need for any type of medically provided prescription.

Most of these illegal pharmacies reside in third world countries (India, China) and are not controlled by the United States. Risks of Having No Prescription Although tablets containing sildenafil citrate can be purchased over the internet without a prescription, there are some risks of doing so that should be noted. First of all, according to U.S. law, it is illegal to sell this and various other drugs without having a prescription from a medical doctor. If you are unsatisfied with such products, you have no recourse for obtaining a refund. Also, because many generic versions of Viagra are not FDA-approved, they can be dangerous to take, causing serious health problems and even loss of life.

You should therefore know that when purchasing Viagra online without having a proper prescription, you do so with the possible health risks in mind. Any men 18 years of age or older that are experiencing problems with Erectile Dysfunction may benefit from tablets containing sildenafil citrate. Erection issues may be caused by physical, psychological, or a combination of these sources and generally last a prolonged period of time. It is recommended that you visit your doctor to discuss any problems with Erectile Dysfunction and have testing done to determine any conditions that may prevent you from taking the medication. If you have certain diseases affecting the heart, kidneys, or central nervous system, and are taking certain types of medication to treat such problems, then you may not be able to take Viagra which contains PDE5 inhibitors.

You should understand that Viagra and other ED drugs cannot be used as aphrodisiacs to boost the desire for sexual activity. Also, these medications do not prevent the transfer of STDs like the AIDs virus. Another reason that you should consult your health practitioner before taking Viagra is that taking the drug can produce various side effects. When Viagra was being tested, participants taking the medication experienced a variety of symptoms that included flushing (blood rushing to the head, neck and face), headaches, itchy skin, aching muscles, bleeding from the nose, indigestion, vision problems and diarrhea. Certain side effects can have adverse medical risks and require that you stop taking the medication and immediately consult trained health providers.

You should do this if you experience sudden rashes, difficulties with breathing, pains in your chest, drops in your ability to hear, blurry or complete loss of your sight, severe light headedness, problems when urinating, or if you lose consciousness. Viagra is dispensed in pills containing 25, 50 and 100 milligrams of the active ingredient sildenafil citrate. Doctors normally begin patients with the smallest dose to see how they respond since the effects vary between persons. If all goes well, doses are increased. Dosage can be further controlled by cutting the tablets into smaller pieces with cutters made especially for this purpose.

Viagra or generic pills containing sildenafil citrate are taken when sexual activity is anticipated approximately a half hour beforehand. However, you should not take more than one Viagra tablet in a period of 24 hours. The ability to have strong erections can as long as five hours after taking the medication, but sexual desire must be present before they will work effectively. If you experience an erection that endures longer than the expected timeframe, or you take too much of the medication, you should contact a medical professional as soon as possible.
