Levaquin Lawyer Argues that Johnson & Johnson Knew About Tendon Risks
A Levaquin side effects lawsuit filed on September 27, 2011, in U.S. District Court for the District of Colorado alleges that problems associated with Levaquin’s predecessor drug Ofloxacin should have made Johnson & Johnson aware of the increased risk of Levaquin side effects, including Levaquin tendon rupture.
Plaintiff files Levaquin side effects lawsuit
Plaintiff Richard McCullough claims he experienced Levaquin tendon rupture in both of his shoulders as a result of taking the broad-spectrum antibiotic for 10 years. The exact cause of Levaquin tendon rupture, which has prompted many patients to contact a Levaquin lawyer and file a Levaquin side effects lawsuit, is unknown, but physicians believe the drug contributes to cell death, which can lead to Levaquin tendon rupture. Plaintiffs in a Levaquin side effects lawsuit have complained of both rotator cuff tears, as well as tears of the Achilles heel. Levaquin tendon rupture can take six weeks to six months to heal and can lead to decreased mobility.
Levaquin lawyer: tendon side effects preceded Levaquin
McCullough and his Levaquin lawyer allege that Johnson & Johnson knew about the risk of Levaquin tendon rupture as a result of Levaquin’s predecessor, Ofloxacin, being pulled from the market.
According to the complaint in McCullough’s Levaquin side effects lawsuit, both Levaquin and Ofloxacin are fluoroquinolone antibiotics, which are known for having side effects that include a high incidence of muscle damage, such as Levaquin tendon rupture. Ofloxacin was introduced in Japan in 1985. It was introduced in the U.S. as Floxin in 1991.
The Japanese company that sold Ofloxacin created an international database to track the drug’s side effects. Johnson & Johnson had direct access to this database, according to McCullough’s Levaquin tendon rupture lawsuit. In 1992, many fluoroquinolones were removed from the market for causing dangerous side effects including tendonitis and muscle damage.
Elderly at higher risk of Levaquin tendon rupture
According McCullough’s Levaquin lawyer, as Johnson & Johnson was preparing to launch Levaquin, the company stated that the risks associated with the drug would be nearly identical to those associated with Ofloxacin. When Levaquin went on the market, Johnson & Johnson included tenotoxicity as a side effect but failed to mention the increased risk of Levaquin tendon rupture or a heightened risk of all Levaquin side effects in users over the age of 60, or those concurrently using corticosteroids.
McCullough and his Levaquin lawyer suggest that, based on the tendon issues with Ofloxacin, Johnson & Johnson knew about with the similar risks of Levaquin tendon rupture, but intentionally withheld this information about Levaquin side effects from users.
