Hello,

Like all medications , yes it has an expiration date.-

As a drug sits around, it begins to degrade, thereby losing its effectiveness. The drug does not all degrade at the same time but rather over a period of time. The potency begins to decrease. The result is unpredictable results. The manufacturer puts an expiration date so that they can guarantee its effectiveness and potency through that date.

Take care an have a good weekend.-

Note: There is only 1 manufacture of the TRUE Viagra, and that is Pfizer Pharmaceuticals.-
