 The storage life of Viagra (Sildenafil Citrate), as stated by the manufacturer Pfizer, is four years. Cutting it in half does not affect this storage life or potency, as long as it is stored per directions. Of course, half a pill may not be as effective. Some men achieve acceptable results with a 100 mg pill cut in half.
