Drug Update: Patent expirations of Levaquin, Singulair, Avelox and Xyzal

Let's review 2011 first.  No branded products were removed from the market, which is good.  Due to an earlier decision by the F.D.A., generic combinations of antihistamines and decongestants will not be available by prescription in the U.S.  The Allergy Dude can not vouch for medications bought outside of the U.S. since there may be issues about "who is responsible quality control of the product?".
