Levofloxacin lactate Injection
What is levofloxacin?
Levofloxacin is an antibiotic that that may be used to treat different types of bacterial infections. Levofloxacin may also be used to treat people who have been exposed to anthrax or certain types of plague.
Levofloxacin is usually only used for bacterial infections that cannot be treated with safer antibiotics. This is because levofloxacin is a fluoroquinolone (flor-o-KWIN-o-lone) antibiotic and fluoroquinolone antibiotics can cause serious or disabling side effects.
Before taking this medicine
You should not use levofloxacin if you are allergic to it or other fluoroquinolones (such as ciprofloxacin, gemifloxacin, moxifloxacin, norfloxacin, ofloxacin, and others).
Levofloxacin may cause swelling or tearing of a tendon (the fiber that connects bones to muscles in the body), especially in the Achilles’ tendon of the heel. This can happen during treatment or up to several months after you stop taking levofloxacin. Tendon problems may be more likely in certain people (children and older adults, or people who use steroid medicine or have had an organ transplant).
Tell your doctor if you have ever had:
- tendon problems, bone problems, arthritis or other joint problems (especially in children);
- blood circulation problems, aneurysm, narrowing or hardening of the arteries;
- heart problems, high blood pressure;
- a genetic disease such as Marfan syndrome or Ehler’s-Danlos syndrome;
- a muscle or nerve disorder, such as myasthenia gravis;
- kidney disease;
- seizures or epilepsy;
- a head injury or brain tumor;
- long QT syndrome (in you or a family member); or
- low levels of potassium in your blood (hypokalemia).
Do not give this medicine to a child without medical advice.
How should I take levofloxacin?
Follow all directions on your prescription label and read all medication guides or instruction sheets about levofloxacin.
Take levofloxacin with water, at the same time each day. Drink extra fluids to keep your kidneys working properly while taking levofloxacin.
