Have you noticed Excedrin's absence from pharmacies?
On January 8, 2012, the pharmaceutical manufacturer Novartis announced a massive recall of its Excedrin, No-Doz, Bufferin and Gas-X products and six months later it is still off the shelves.
So have you noticed Excedrin's absence?
Novartis attributed the recall to problems at its Nebraska plant that could have led to contamination by other medications produced there, according to ABC News.
In a statement, Novartis said it was "working very hard to return products to store shelves." The company plans to restart production on a "line-by-line, product-by-product basis" to assure quality, and hopes to start restocking some products in the second half of the year.
There is no word yet on which of the recalled products will be manufactured first, but many people are beginning seek the product elsewhere, like eBay.
