Why can't I find nuprin (ibuprofen) anywhere?

Discontinued. Nuprin was discontinued by bristol myers squibb many years ago. The remaining supply was sold in a few stores. However nuprin is just a brand name of ibuprofen. Nuprin, advil, Motrin all have the exact same medicine - ibuprofen. So just use advil or any other generic brand (like cvs, walmart, walgreens) - just check that it says the active ingredient is ibuprofen.
