It was announced on December 4 that Mylan Pharmaceuticals has been granted tentative approval by the US Food and Drug Administration (FDA) to market a generic form of the fluoroquinolone antibiotic in 250, 500 and 750 mg tablets. It is not known when Mylan will bring its generic form of Levaquin to market.
Levofloxacin, a fluoroquinolone antibiotic, is a powerful drug used to treat a range of bacterial sinus and bronchial infections as well as certain genitourinary infections and bacterial skin infections. Critics have long derided the drug for its plethora of side effects ranging from tendon rupture to neurological disorders.
Will there be more Levaquin lawsuits?
With the inclusion of Levaquin in the ranks of the generics, it appears that things may get worse before they get better. Currently, Levaquin is out of reach to patients who cannot afford the expensive brand-name drug or whose health plan does not shoulder the cost. Generics, on the other hand, are usually less expensive. The generic version of Levaquin will undoubtedly introduce the antibiotic to a new sector of the population and a new generation of users.
There are other generic manufactures besides Mylan that have lined up for approval to manufacture and market fluoroquinolones. Ivax, Actavis and Lupin Pharmaceuticals have also gained tentative FDA approval to market generic versions of Levaquin.
