Yes and loss it's effectiveness when expires. Any prescription drugs have expiration date same with viagra, but I doubt that not all viagra indicates expiration date so it is really hard to tell when does it expires if that's the case.
viagra
Expiration means that the drug is no longer effective after that date.
The active ingredient in Viagra is sildenafil citrate. "Viagra" is the trade name used by Pfizer.

You can use Viagra if you have herpes.
can i take viagra after bear...??
i never use Viagra
Never heard of Pro Viagra as such. If you mean to say generic Viagra,then 1] Both generic and brand Viagra gives same effect, both differ in price. Generic Viagra is cheap while brand is costly. 2] You require prescription for brand Viagra while generic doesn't require prescription. 3] Generic Viagra has more chance of showing side effect, while brand has less because you acquire Viagra prescription once doctor recommend you based on your health for brand Viagra.
using Viagra in regural base is not good.
