What is Tequin?
Tequin (gatifloxacin) is an antibiotic used to treat adults with lung, sinus, or urinary tract infections, as well as certain sexually transmitted diseases (STDs) caused by germs called bacteria. Tequin does not kill viruses which attack the lungs and sinuses, and while it treats gonorrhea, it does not treat other STDs like syphilis and non-gonococcal diseases.
Tequin is a drug made by Bristol-Myers Squibb Company and was approved for use by the U.S. Food and Drug Administration (FDA) in December 1999.
Tequin FDA Alert
In March 2006, the FDA announced that Bristol-Myers Squibb Company revised the labeling on Tequin because it caused some people to have serious blood sugar problems (low blood sugar or high blood sugar). Click here to see the FDA alert.

Other Recommendations When Taking Tequin
When taking Tequin, it is recommended that you:

Tequin - Getting Legal Help
While all medications have certain anticipated side effects, a drug manufacturer has a duty to make its products as reasonably safe as possible, and to inform the medical community and the public of known risks associated with its drugs. If a manufacturer fails to do so, it can be held legally responsible if patients are injured as the result of inadequate warnings or the unreasonably dangerous nature of the drug, under a legal theory called "product liability."
If you or a loved one have experienced any dangerous symptoms or unusual medical conditions while taking Tequin, you should first contact your doctor or other healthcare professional. You may also wish to meet with an experienced attorney to discuss your options and to protect your right to a legal remedy for any injury caused by Tequin use.
