Levaquin is a broad spectrum antibiotic, which means that it’s used to treat a long list of bacterial infections and is also approved for treatment of bronchitis and pneumonia. It was developed by Ortho-McNeil Pharmaceuticals. Levaquin belongs in the fluroquinolone class of drugs. It is used to treat bacterial infections of the skin, sinuses, kidneys, bladder, or prostate. It has also been prescribed to people who have been exposed to anthrax or plague.
The FDA originally approved Levaquin in its current brand name in 1996. After a few years on the market, Levaquin began to be linked to serious side effects.
After more than 12 years on the market, Levaquin had generated a high enough number of negative incidents that were reported to the FDA to warrant action. In July of 2008, the FDA issued a statement that it was ordering the makers of Levaquin to place a black box warning on the label about associated risks.
The fluroquinolone class has been associated with ruptured tendons and tendinitis. In 2011, healthcare experts had attributed 60 percent of all tendon injuries in the United States to the use of Levaquin. Ruptures of the Achilles tendon, hand, shoulder or other tendons requiring surgical treatment have been reported.
