The antibiotic Tequin, plagued by serious blood-sugar complications, is coming off the market.
Levin Papantonio is not currently accepting cases related to Tequin at this time.
Tequin, also known as gatifloxacin, is an antibiotic used to treat adults with lung, sinus, or urinary tract infections and also to treat certain sexually transmitted diseases caused by germs called bacteria. Sometimes viruses, rather than bacteria, may infect the lungs and sinuses (for example, the common cold). Tequin, like all other antibiotics does not kill viruses. Tequin treats the sexually transmitted disease called gonorrhea. Tequin does not treat other sexually transmitted diseases, including syphilis and non-gonococcal diseases.
Bristol-Myers Squibb manufactures Tequin, which belongs to the class of drugs known as fluoroquinolones. The U.S. Food and Drug Administration approved Tequin in 1999. On April 27, 2006 Bristol-Myers Squibb Co. announced that it would stop making & selling Tequin (gatifloxacin), as the drug has been associated with hyperglycemia (high blood sugar) and hypoglycemia (low blood sugar), both of which are potentially fatal blood-sugar disorders.
Potential side effects of Tequin include, but may not be limited to, nausea, vomiting, stomach pain, diarrhea, dizziness and headache.
Fluoroquinolones, such as Tequin, have been linked to serious side effects. The medication should stop being used immediately if a patient experiences any of the following symptoms:
- An allergic reaction (difficulty breathing; closing of the throat; swelling of the lips, tongue, or face; or hives)
- Central nervous system (CNS) side effects including: seizures, dizziness, confusion, tremors, hallucinations, depression, or suicidal thoughts
- Pain, inflammation, or rupture of a tendon
- Hematologic and immunologic adverse reactions
- Liver problems
In 2006, Bristol-Myers announced labeling changes for Tequin. The labeling changes, announced by the Tequin manufacturer in a letter to healthcare professionals, updated the prescription information as a result of continued reports of serious cases of hypoglycemia (low blood sugar) and hyperglycemia (high blood sugar) in patients receiving Tequin. Since the approval of Tequin in 1999, there have been rare cases of life-threatening events reported globally in patients treated with the drug. Most of these events were reversible when properly managed, but a few had fatal outcomes.
If you have taken Tequin, it may be advisable to seek both medical attention, to protect your health, and legal counseling, to protect your rights. Please keep in mind that there may be time limits within which you must commence suit.
