Tequin® (gatifloxacin)

Tequin (gatifloxacin) is an antibiotic medication used to treat adults with lung, sinus, or urinary tract infections, as well as certain sexually transmitted diseases caused by bacteria. Manufactured by Bristol-Myers Squibb Company, Tequin works by stopping the growth of bacteria and belongs to a class of drugs called quinolone antibiotics.

Tequin only treats bacterial infections. It does not work for viral infections, e.g., the common cold, flu. 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 warnings and alerts

In 2006, the FDA notified healthcare professionals about proposed changes being made to the prescribing label ‘Warnings’ section for Tequin, noting that hypoglycemia (low blood sugar) and hyperglycemia (high blood sugar) have been associated with use, and that the drug is contraindicated in diabetic patients. Other serious side effects include severe allergic reactions, seizures, dizziness, confusion, tremors, hallucinations, depression, suicidal thoughts, or pain, heart attack, stroke, and death. Public Citizen, the public interest group founded by Ralph Nader, filed a petition with the Food and Drug Administration demanding a Tequin recall. The petition made reference to 388 patients with blood-sugar irregularities associated with Tequin, including 20 deaths and 159 hospitalizations since January 2000.

Tequin FAQs

What is Hypoglycemia?

Hypoglycemia is the term used to describe the condition caused by abnormally low blood sugar levels. If you are taking Tequin, medical attention should be sought immediately if you experience:

  • Confusion
  • Seizures
  • Loss of consciousness

What is Hyperglycemia?

Hyperglycemia is the term used to describe abnormally elevated blood sugar levels, a condition classically associated with diabetes.

Has Tequin been recalled?

No. Although Bristol-Myers Squibb no longer manufactures the drug, there is no plan to recall existing product in the market. In fact, the manufacturer is warning Tequin users not to stop taking it without first discussing the matter with their doctor.

Who should NOT take Tequin?

You should not Tequin if you are allergic to it or any ‘quinolones’ such as:

  • Ciprofloxacin
  • Gatifloxacin (Tequin, Zymar)
  • Levofloxacin (Levaquin)
  • Lomefloxacin (Maxaquin)
  • Moxifloxacin (Avelox, Vigamox)
  • Gemifloxacin (Factive)

  • Take other prescription or non-prescription medicines, vitamins, or herbal supplements — especially those for controlling blood sugar, or treating irregular heartbeat, as well as antidepressant or antipsychotic medicines, diuretics (“water pills”), diabetes medicines, Videx (didanosine), or antacids and multivitamins that contain zinc, magnesium, or iron.

Can I file a lawsuit if I have suffered damages from taking Tequin?

Possibly. While all medications have certain, anticipated side effects, a drug manufacturer has a duty to inform physicians adequately regarding the known risks associated with its drugs. If a manufacturer fails to do so, it can be held responsible to patients who are injured as the result of inadequate warnings, under a legal theory known as “product liability.” Depending upon the particular circumstances of your case, damages may include recovery for any of the following:

  • Past and future medical expenses
  • Past and future pain and suffering
  • Lost wages
  • Loss of future earning capacity
  • Emotional distress

If you or a loved one has experienced any health problems while taking Tequin, you should contact your doctor immediately. You may also wish to contact an experienced Tequin lawyer to discuss your legal options. As all legal claims are subject to time limits, however, you may risk forfeiture of your right to financial compensation if you delay.
