The term "generic" refers to the active ingredient of a medicine or drug rather than to the advertised brand name under which the medicine is sold. It is a term referring to any drug marketed under its chemical name without advertising.
Pfizer made the originaltablet that is often referred to as the “blue pill”.The patent expired in 2013 which then allowed other pharmaceutical manufactures to make a generic version under the name of the active ingredient called Sildenafil. They are exactly the same medically and perform in the same way with the same side-effects.
As with most branded products, Viagra is sold at a higher price,therefore the generic tablets sold asare much cheaper.
Medically there is no difference between a generic medicine and the branded medicine, as they both have the same active ingredients to make them perform in the same way. They only differ in the “bulking” agents used to fill the tablet as the amount of active ingredient required, in this case Sildenafil, is very small. This makes the tablets bigger and easier to handle.
The main difference between generic andbranded named prescription medicines is cost with generics being much cheaper
Every pharmacy can choose what price they sell at, as there are no fixed prices. It will depend on what price the pharmacy can buy the drug from the wholesaler and the cost of their own overheads. They can they decide what mark-up they require and some pharmacies choose to sell some products at higher prices.
