Levaquin

The unit-dose packaging of the quinolone, Levaquin (Levofloxaein antibaeterial), is silver foil with black letters. The dose is reverse shaded. A reporter noted that the packages have to be held at just the right angle to be able to read the label. It was reported to be especially difficult to differentiate between the 250 and 500 mg strengths because the numbers were so diffieult to see. 

The quinoline antibiotics act by inhibiting bacterial DNA gyrase. These include Cipro, Levaquin, Floxacin, and Floxin.

The fluoroquinolone subclass of antibiotics is inspired by nalidixic acid (A.35), an older antibiotic commonly used for urinary tract infections (Figure A.10). Depending on the type of infection, fluoroquinolones inhibit DNA gyrase and/or topoisomerase IV. Both enzymes are vital for DNA replication and bacterial reproduction. Both ciprofloxacin (Cipro, A.36) and levofloxacin (Levaquin, A.37) are examples of fluoroquinolone antibiotics. Ciprofloxacin received national attention in the United States in 2001. Ciprofloxacin was used to treat many anthrax-infected patients after letters containing anthrax spores were sent through the U.S. postal service. 

Many other commonly used antibiotics can cause psychiatric symptoms, for example, clarithromycin (trade name, Biaxin)—which is frequently used to treat respiratory illness, ear infections, and skin infections—has been reported to cause mania in some patients. Metronidazole (trade name Flagyl), which is used to treat many types of infections—from parasites to vaginal infections and abscesses—has been reported to cause depression, agitation, confusion, hallucinations, and mania. Trimethoprim-sulfamethoxazole (trade names Bactrim and Septra)—which is used, for example, for bladder infections and sinus and ear infections—has been reported to cause delirium, psychosis, depression, and hallucinations in rare cases. The fluoroquinolone antibiotics—such as ciprofloxacin (trade name Cipro), levofloxacin (trade name Levaquin), ofloxacin (trade name Floxin), trovafloxacin (trade name Trovan), and others of this class—can cause psychiatric symptoms fairly often, including confusion, agitation, depression, insomnia, mania, paranoia, and psychosis.
