What is the difference between Viagra and Sildenafil?

Chemically, Viagra and Sildenafil are the same drug. They both have the same ingredients list (sildenafil). The only difference is that Viagra has a brand name on it, which makes it more expensive, whereas Sildenafil is what is known as a “generic” drug. There is no difference in side effects, dosage, or interference with other medications between the two products.

However, if you have previously been taking Viagra, and are taking multiple medications that mean you may get them confused if you changed the name/packet type of your painkiller, you may wish to continue taking Viagra.

How does Sildenafil work?

Sildenafil contain the an ingredient of the same name, which belongs to a group of medicines called PDE5 inhibitors. The treatment works by relaxing blood vessels in the penis, allowing blood to flow more freely.

  • Headaches
