Pfizer sildenafil : real or fake?

Question: Is pfizer sildenafil a fake generic?

Answer:No. Pfizer has just lost his patent for manufacturing Viagra, which means other pharmaceutical companies are now allowed to produce this medication as well. A copy of an original medication is called "generic". When a patent for a branded drug (such as Viagra) hasn't expired, it is illegal to produce this drug, When the patent has expired however, it is legal. Pfizer sildenafil is a generic version that Pfizer itself has launched. It is the same shape as the original Viagra pills, but these are now white instead of blue. That's why some people call it "White Diamond". This product is a cheaper version of Sildenafil. It is not available over the counter, you still need a prescription to buy it.
