Before comparing "real" Viagra and "generic Viagra" formulas, it is important to get accustomed to the generic name of the drug: Sildenafil Citrate

Generic Viagra (Sildenafil Citrate) is chemically equivalent to the brand name drug Viagra (made by Pfizer).

Almost all of the ingredients in generic Viagra are in identical proportions to real Viagra, but is sold at a much lower price than real Pfizer Viagra.

Sildenafil Citrate is the generic name of the drug, and Sildenafil Citrate is used like real certified Viagra (made by Pfizer and distributed in the UK by official online supplier UKMeds4U.com, in addition to legally supplying other valid prescription medications to help combat Male Impotence [erectile dysfunction or ED] such as Cialis and Levitra).

Generic Viagra (Sildenafil Citrate) is available on the internet through online pharmacies. Because of the popularity of legitimate Viagra (Sildenafil Citrate, developed by Pfizer), many fake online pharmacies sell generic Viagra.

It is important to make sure that the purchase of ANY prescription medication, including branded Viagra and generic Viagra (Sildenafil Citrate), is from a reputable and legal source (like UKMeds4U.com).

Generic Viagra should have the same active ingredient (Sildenafil Citrate) formula as branded Viagra, and  work exactly the same.

Legal, branded Viagra is attainable at great value-for-money from UKMeds4U.com, the UK's leading internet merchant of authentic apportioned treatments to redress infecundity in males, along with other erectile dysfunction medicines, such as Levitra and Cialis.

The drugs can be identical in terms of quality, purity, strength, dosage and take the same amount of time to work.

However, there are MANY illegal and unregulated manufacturers and suppliers of generic medication on the Internet.

Therefore, it is ESSENTIAL to be sure that your supplier is COMPLETELY LEGAL & REGULATED (as UKMeds4u.com is, in the UK), otherwise the alleged generic Viagra you purchase may not work at all, or worse still, it may casue you to be ill, cause major inury, or even kill you.

Sildenafil Citrate

Generic Viagra (or Sildenafil citrate), is a medicine that works by enhancing blood flow into the penis to achieve and maintain an erection.

It is mandatory that the medicine (whether real, branded Viagra or generic Viagra) be taken only under the advice of your doctor, by prescription.

You should not take branded Viagra nor generic Viagra if you are taking nitroglycerin (or other nitrates) or any other recreational drug known as ‘poppers’, which contain amyl or butyl nitrate.

If you are not sure whether any drug that you are taking contains nitrate, you can contact your pharmacist or doctor to find out.

You need additional monitoring of your dose and medication if you are taking any other drug for medical conditions including impotence or high blood pressure.

If you are taking an HIV protease inhibitor, it is recommended that you do not take more than a 25mg dose of branded Viagra or generic Viagra in a 2-day period. You should not begin or stop any medication without your doctor’s approval.

FDA Guidelines

The FDA has come up with a few manufacturing standards, identical to the brand drugs, and includes a wide array of tests to ensure that generic Viagra is the same as the name brand drug.

According to FDA guidelines, once the patent of a medicine like Viagra expires, other pharmaceutical companies are free to make generic forms of it (Sildenafil Citrate, like Sildenafil Teva).

The American Medical Association has endorsed generic drugs (like Sildenafil Citrate) as acceptable for the American public. According to one study, 50% of prescriptions in US are filled by generic drugs. This number is expected to rise to 75-85%.
