Sildenafil and Viagra work in the same way; they’re equally effective, take the same amount of time to work, and last the same amount of time.
Sildenafil and Viagra differ primarily in terms of branding and price. Viagra tablets will always be more expensive than generic Sildenafil.
Sildenafil and Viagra are, in essence, the same medication with the same active ingredient. The kamagra jelly is the generic (non-branded) version, whereas Viagra is the well-known little blue pill brand.
Despite the fact that Sildenafil appears to be a relatively new ED medication, there are no compelling reasons to choose Viagra over Sildenafil.
